Groundbreaking study exposes hidden struggles of ex-Jehovah’s Witnesses in the UK

Humanists: Groundbreaking study exposes hidden struggles of ex-Jehovah’s Witnesses in the UK

A groundbreaking study published in The International Journal for the Psychology of Religion has shed light on the profound and long-lasting challenges faced by people leaving the Jehovah’s Witnesses and ways in which targeted support can assist their recovery.

Conducted by a national group of academic researchers in collaboration with Faith to Faithless, the Humanists UK programme supporting people who leave high-control religions, the research involved in-depth interviews with 20 ex-Jehovah’s Witnesses in the UK. Participants described significant emotional, social, and practical struggles after leaving – often compounded by shunning, loss of identity, and a lack of understanding from professionals.

The study found:
• Many experience acute mental health issues, including anxiety, depression, and PTSD, linked both to life inside the religion and to the process of leaving.
• Social isolation is common, with loss of family and friends leaving some feeling like ‘a little baby’ navigating the outside world for the first time.
• Professional help is often ineffective due to a lack of awareness about religious trauma.
• Recovery is possible – but requires specialist understanding, safe environments, and supportive relationships.

The authors emphasise that leaving a high-control religion is not a single event but ‘a complex, ongoing process of rebuilding identity and worldview.’ With the right support from trained mental health professionals, informed social services, and community networks, former members can ‘piece everything together again’ and go on to live fulfilling lives.

Caring in the Shadows: Emotional and Caregiving Challenges Faced by Families of Individuals in Coercive Controlling Groups and Relationships

Journal of Family Violence: Caring in the Shadows: Emotional and Caregiving Challenges Faced by Families of Individuals in Coercive Controlling Groups and Relationships

Carmen Almendros, Francisco González-Espejito, …Rubén García-Sánchez

Abstract
Purpose
Studies on families of individuals experiencing coercive control have generally considered them as informants or supporters, often overlooking their own difficulties and needs. Evidence from other areas highlights the importance of acknowledging family emotions and caregiving experiences, emphasizing their impact on family mental health and the progression of their relatives’ condition. This study aimed to explore the emotional and caregiving challenges faced by family members and friends of individuals in coercive controlling groups and relationships, along with their associations with distress, well-being, and mastery.

Methods
Using data from the Family Caring Survey, a quantitative study investigating family members’ experiences and needs, we examined the factor structure, internal reliability, measurement invariance across gender, and criterion-related validity of the Family Questionnaire (FQ) and the Brief Experience of Caregiving Inventory (BECI) in a convenience sample of 264 family members of individuals in coercive controlling groups or relationships.

Results
Interpretable and well-fitting factor structures emerged for both the FQ (intense emotional expression, over-concern, critical comments, monitoring) and BECI (stigma, difficult behaviors, positive personal experiences). Families face substantial emotional turmoil and caregiving challenges, significantly related to distress, anxiety, depression, and lower mastery. Stigma and Intense Emotional Expression were notably linked to poorer mental health outcomes. Strong ties existed between Difficult Behaviors and Critical Comments, both strongly associated to potential family separation. Gender differences in caregiving experiences and expressed emotion were mostly nonsignificant, though women exhibited a slightly heightened Over-Concern.

Conclusions
The findings provide insights to understand the unique challenges these families face, underscoring the importance of developing family-based intervention programs and enhancing support for a population traditionally marginalized in scientific literature.

Paranormal Phenomena Met With Skepticism in U.S.

Paranormal Phenomena Met With Skepticism in U.S.

Two-thirds of Americans are skeptical of paranormal beliefs; none of eight concepts are believed by a majority.

"Americans are broadly skeptical about each of eight paranormal phenomena tested in a recent Gallup poll. Nearly half of U.S. adults, 48%, believe in psychic or spiritual healing. Slightly fewer, 39%, express a belief in ghosts, while between 24% and 29% say they believe in six other supernatural phenomena, including telepathy, communication with the dead, clairvoyance, astrology, reincarnation and witches.

For each of these paranormal phenomena, respondents were asked whether or not they believe in it or are unsure. Roughly one in five Americans are unsure about each of them, while at least half say they don’t believe in clairvoyance (50%), reincarnation (50%), astrology (55%) or witches (60%)."

" ... These findings are based on a Gallup poll conducted May 1-18, 2025.

Americans’ levels of belief in five of the eight paranormal phenomena are statistically similar to Gallup’s 2001 readings. Gallup has previously asked about various paranormal phenomena in 1990, 1991, 1994, 1996, 2001 and 2005 surveys. Comparisons to some of these past data are complicated by whether the paranormal questions were preceded by questions about religion, which appear to influence the way people think about communicating with the dead and ghosts or spirits.

The 1994, 2001 and 2025 surveys included religion questions. A comparison of the 2025 results with those from 2001 shows that Americans’ beliefs in paranormal phenomena are largely unchanged. The exceptions are six-percentage-point declines in belief in psychic or spiritual healing and clairvoyance, and a seven-point drop in belief in telepathy."

Conspiracy Beliefs and Consumption: The Role of Scientific Literacy

Conspiracy Beliefs and Consumption: The Role of Scientific Literacy

Abstract

Conspiracy theories pose risks to consumers, businesses, and society. The present research investigates the role of scientific literacy in a variety of conspiracy beliefs with implications for consumer well-being and sustainability (e.g., regarding coronavirus disease 2019 [COVID-19], genetically modified organisms, and climate change). In contrast to the mixed effects of education in prior work, we find that scientific literacy undermines conspiracy beliefs and, in turn, conspiracy-related behaviors. This finding is explained by people’s ability to use two dimensions of scientific literacy—scientific knowledge and reasoning—to accurately assess conspiracy evidence. For robustness, we assess scientific literacy through both measurement and manipulation (i.e., interventions), identify two moderators (evidence strength and narration) that attenuate the effect, and further validate our theorizing using national and international datasets (regarding COVID-19 vaccination and Google search, respectively). We discuss the implications of our findings for consumers, companies, nonprofit organizations, and governments.

Have we reached peak yoga in the U.S.? The CDC wants to know

Have we reached peak yoga in the U.S.? The CDC wants to know

June 12, 2024

In the U.S., about 1 out of 6 adults say they practice yoga, according to new survey data published Wednesday by the Centers for Disease Control and Prevention.

About 80% are practicing to improve their health, and some 30% are using it to treat and manage pain.

“Yoga is a complementary health approach used to promote health and well-being,” says Nazik Elgaddal, an IT specialist at the CDC’s National Center for Health Statistics who co-authored a data brief on the topic.” The stretching and strengthening exercise has been shown to reduce stress and help with some types of neck and back pain.

The survey also found that women are twice as likely to do yoga than men – with more than 23% of U.S. women practicing it. Yoga is most popular among people who are Asian or White, though there are plenty of people who are Black, Hispanic or of other races doing yoga too. People with higher incomes were more likely to do yoga.

The survey did not distinguish between yoga done in person or online, notes Elgaddal, who takes yoga classes offered by her workplace on Zoom. It found that more than half of the respondents also meditate as a part of their practice.

The data comes from the 2022 National Health Interview Survey, and is published in a June 2024 data brief. Every five years, the NHIS includes questions on complementary health, including yoga.

A previous analysis showed that complementary approaches in the U.S. have grown in popularity over the past twenty years. Yoga experienced the largest increase in that time, going from being practiced by 5% of the adult population in 2002 to 16% in 2022.

In that time, yoga has become so ubiquitous that it’s hard to parse, says Ophelia Yeung, a senior research fellow at the Global Wellness Institute, which studies the economics of the $5.6 trillion global wellness industry. “There are lots of people doing [yoga] on different online platforms – Peloton, Apple Fitness, Netflix, Youtube” to name a few, Yeung says, “If you ask a consumer which part of their [subscription] spending is for fitness and which part is for entertainment, it’s all bundled,” she says.

It has also become more accessible over time, Yeung says, noting that there's now versions adapted for back injury, for inflexibility, for practicing with goats and dogs. There are also yoga classes designed to be welcoming for larger bodies, for those with disabilities and for populations such as school kids and veterans.

Yoga’s mainstream popularity has spawned yoga-influenced offshoots, such as mobility workouts and mindfulness, which are so evolved from its roots that the people who practice them may not realize they are related, says Rebecca D’Orsogna, a high school social studies teacher in New York who wrote a doctoral dissertation on the history of yoga in the U.S.

“Parts of the yoga practice are taken out of the context of yoga and put somewhere else…to the point where people are almost unwittingly doing it,” she says.

D’Orsogna traces the current yoga wave to the late 1960’s, when The Beatles brought an explosion of interest to the work of the Maharishi Mahesh Yogi and his Transcendental Meditation after a trip to India.

“[Western adopters] considered it to be ‘more authentic’ yoga because it is connected directly to India, as opposed to what had been cobbled together within the United States [before that],” she says, noting a periodic cropping up of interest in yoga in U.S. pop culture that stretches back to the naturalist philosophers of the 1800’s.

That thread of interest waxed with the new age movement in the 1970’s, and waned with the aerobics fitness trend in the 80’s, but it’s since gained a firm foothold in U.S. mainstream culture, D’Orsogna says. She says the practice is linked with women’s empowerment and self-actualization. “The overarching history of yoga in the United States is that people who popularize it use it for whatever the cultural moment calls for,” she says.

Yoga has become big business – the largest contributor to the “mindful movement” market, which also includes practices such as pilates and tai chi, worth $12.7 billion in the U.S. in 2022, according to data from the Global Wellness Institute. Mindful movement soared in popularity during the COVID-19 pandemic – spending increased by 17% from 2019 to 2022 on things like classes, equipment and retreats – as people looked to it as a way to maintain fitness and alleviate stress, says Yeung.

Still, the benefits of yoga – stress relief, pain relief and cultivating a connection between the mind and the body – can be obtained for little to no money, Yeung says.

“There are tons of free opportunities online and in communities,” she says, such as videos on Youtube that offer high quality instruction. At its core, practicing yoga postures requires a clear surface and a willingness to stretch.

I like it because it hurts you: On the association of everyday sadism, sadistic pleasure, and victim blaming.

Citation
Sassenrath, C., Keller, J., Stöckle, D., Kesberg, R., Nielsen, Y. A., & Pfattheicher, S. (2024). I like it because it hurts you: On the association of everyday sadism, sadistic pleasure, and victim blaming. Journal of Personality and Social Psychology, 126(1), 105–127.

Abstract
Past research on determinants of victim blaming mainly concentrated on individuals’ just-world beliefs as motivational process underlying this harsh reaction to others’ suffering. The present work provides novel insights regarding underlying affective processes by showing how individuals prone to derive pleasure from others’ suffering—individuals high in everyday sadism—engage in victim blaming due to increased sadistic pleasure and reduced empathic concern they experience. Results of three cross-sectional studies and one ambulatory assessment study applying online experience sampling method (ESM; overall N = 2,653) document this association. Importantly, the relation emerged over and above the honesty–humility, emotionality, extraversion, agreeableness, conscientiousness, and openness personality model (Study 1a), and other so-called dark traits (Study 1b), across different cultural backgrounds (Study 1c), and also when sampling from a population of individuals frequently confronted with victim–perpetrator constellations: police officers (Study 1d). Studies 2 and 3 highlight a significant behavioral correlate of victim blaming. Everyday sadism is related to reduced willingness to engage in effortful cognitive activity as individuals high (vs. low) in everyday sadism recall less information regarding victim–perpetrator constellations of sexual assault. Results obtained in the ESM study (Study 4) indicate that the relation of everyday sadism, sadistic pleasure, and victim blaming holds in everyday life and is not significantly moderated by interpersonal closeness to the blamed victim or impactfulness of the incident. Overall, the present article extends our understanding of what determines innocent victims’ derogation and highlights emotional mechanisms, societal relevance, and generalizability of the observed associations beyond the laboratory.

Many people believe at least one conspiracy theory. And that isn't necessarily a bad thing – conspiracies do happen.

To take just one example, the CIA really did engage in illegal experiments in the 1950s to identify drugs and procedures that might produce confessions from captured spies.

However, many conspiracy theories are not supported by evidence, yet still attract believers.

For example, in a previous study, we found about 7% of New Zealanders and Australians agreed with the theory that visible trails behind aircraft are "chemtrails" of chemical agents sprayed as part of a secret government program. That's despite the theory being roundly rejected by the scientific community.

The fact that conspiracy theories attract believers despite a lack of credible evidence remains a puzzle for researchers in psychology and other academic disciplines.

Indeed, there has been a great deal of research on conspiracy theories published in the past few years. We now know more about how many people believe them, as well as the psychological and political factors that correlate with that belief.

But we know much less about how often people change their minds. Do they do so frequently, or do they to stick tenaciously to their beliefs, regardless of what evidence they come across?

From 9/11 to COVID

We set out to answer this question using a longitudinal survey. We recruited 498 Australians and New Zealanders (using the Prolific website, which recruits people to take part in paid research).

Each month from March to September 2021, we presented our sample group with a survey, including ten conspiracy theories, and asked them how much they agreed with each one.


All of these theories related to claims about events that are either ongoing, or occurred this millennium: the September 11 attacks, the rollout of 5G telecommunications technology, and COVID-19, among others.

While there were definitely some believers in our sample, most participants disagreed with each of the theories.

The most popular theory was that "pharmaceutical companies ('Big Pharma') have suppressed a cure for cancer to protect their profits". Some 18% of the sample group agreed when first asked.

The least popular was the theory that "COVID-19 'vaccines' contain microchips to monitor and control people". Only 2% agreed.


Conspiracy beliefs probably aren't increasing

Despite contemporary concerns about a "pandemic of misinformation" or "infodemic", we found no evidence that individual beliefs in conspiracy theories increased on average over time.

This was despite our data collection happening during the tumultuous second year of the COVID-19 pandemic. Lockdowns were still happening occasionally in both Australia and New Zealand, and anti-government sentiment was building.

While we only tracked participants for six months, other studies over much longer time frames have also found little evidence that beliefs in conspiracy theories are increasing over time.

Finally, we found that beliefs (or non-beliefs) in conspiracy theories were stable – but not completely fixed. For any given theory, the vast majority of participants were "consistent sceptics" – not agreeing with the theory at any point.

There were also some "consistent believers" who agreed at every point in the survey they responded to. For most theories, this was the second-largest group.

Yet for every conspiracy theory, there was also a small proportion of converts. They disagreed with the theory at the start of the study, but agreed with it by the end. There was also a small proportion of "apostates" who agreed with the theory at the start, but disagreed by the end.

Nevertheless, the percentages of converts and apostates tended to balance each other pretty closely, leaving the percentage of believers fairly stable over time.



Inside the 'rabbit hole'

This relative stability is interesting, because one criticism of conspiracy theories is that they may not be "falsifiable": what seems like evidence against a conspiracy theory can just be written off by believers as part of the cover up.

Yet people clearly do sometimes decide to reject conspiracy theories they previously believed.

Our findings bring into question the popular notion of the "rabbit hole" – that people rapidly develop beliefs in a succession of conspiracy theories, much as Alice tumbles down into Wonderland in Lewis Carroll's famous story.

While it's possible this does happen for a small number of people, our results suggest it isn't a typical experience.

For most, the journey into conspiracy theory belief might involve a more gradual slope – a bit like a real rabbit burrow, from which one can also emerge.

Work wellness programs have zero mental health benefits, study says

People who participate in work-led mindfulness trainings, apps and more see no benefit, according to Oxford University.

Victoria Wells
Financial Post
January 23, 2024

Employers sinking money into workplace wellness programs such as mindfulness training, on-site massages and meditation apps might want to think again because new research suggests the programs do absolutely nothing to buoy mental health.

People who take part in well-being programs aimed at teaching them how to firm up their mental health get zero benefits when compared to employees who don’t participate, according to an Oxford University study of more than 46,000 British employees at over 200 companies. The research, released Jan. 10, examined how workers’ well-being fared after participating — or not — in programs ranging from volunteering and charity work to mindfulness classes to apps promoting well-being and healthy sleep habits.

Oxford researcher William Fleming then compiled data from employees across a wide range of industries and positions who had anonymously answered survey questions about their stress levels, job satisfaction and sense of belonging, among other indicators. “Across multiple subjective well-being indicators, participants appear no better off,” Fleming said in the report. “Results show that those who participate in individual-level interventions have the same levels of mental well-being as those who do not.”

The findings are the exact opposite of a narrative that has helped fuel the adoption of workplace wellness initiatives in the United Kingdom, Canada and beyond. “It’s a fairly controversial finding, that these very popular programs were not effective,” Fleming said in the New York Times.
Only one program appeared to boost mental health: volunteering. That could be because charity work helps give people a greater sense of purpose, which increases feelings of belonging, Fleming said. But even then, he sounded a note of caution. “The estimated effects are small, probably selection-biased and these initiatives would not engage with the job demands and resources central to theoretical and empirical understandings of work well-being.”

The findings will no doubt concern some business leaders who’ve sunk large amounts of money and effort into wellness programs to stem increased mental health complaints among workers. Canada is in the midst of a mental health crisis, the Centre for Addiction and Mental Health (CAMH) said, with more than one in two people experiencing a mental illness by the time they’re 40. Indeed, diagnoses have “significantly” grown over the past 10 years, with the pandemic exacerbating depression and anxiety, according to a recent Statistics Canada report.
The economic toll is also enormous. Poor mental well-being costs the country an estimated $51 billion a year in extra health-care costs, lost productivity and quality of life, CAMH estimates. The rising cost of living also hasn’t helped. As inflation increases the cost of food and high interest rates bring heftier mortgage payments, more Canadian workers say they’re under stress. The resulting “financial stress storm” has made people less productive and more prone to absences at work, according to the National Payroll Institute. That’s also expensive since the time people waste at work worrying about money adds up to around $45 billion a year in lost productivity.

At the same time, employees have made it clear they expect their employers to help them manage their mental well-being. For example, three-quarters of Canadians believe workplaces should make their mental health a priority, according to a 2022 study by Capterra Inc. That’s left bosses with the difficult task of finding fixes that actually help people, while also stemming some of the balance-sheet bleeding.
But the Oxford study offers a possible solution for employers wondering what to do — and it’s not a companywide volunteering initiative. “There’s growing consensus that organizations have to change the workplace, not just the worker,” Fleming said.

There’s growing consensus that organizations have to change the workplace, not just the worker - WILLIAM FLEMING, OXFORD UNIVERSITY

Changing the workplace could involve improving flexibility, conducting performance reviews and making jobs better overall, Fleming said. For example, employers could ensure staffers aren’t saddled with too much work, allowing them to complete tasks on time while also eliminating useless time-management training. Some companies may also want to consider pay hikes, he said.

Not all employers are able to hand out raises, of course, but allowing flexible schedules could be a cost-effective fix. Plus, research shows it’s a key want of workers seeking to improve their well-being. As just one example, 81 per cent of Canadians cited a flexible schedule as the top mental health benefit their employer could offer, topping days off for self-care, professional counselling and wellness stipends, Capterra’s survey said. Along those same lines, studies show a four-day workweek brings improved employee satisfaction, happiness and productivity.

Despite the Oxford study’s findings, some companies may be keen to hold onto the wellness initiatives they already have in place. That’s fine, Fleming said, but they’ll still need to make changes if they want mental health to improve. “If employees do want access to mindfulness apps and sleep programs and well-being apps, there is not anything wrong with that,” he said in the Times. “But if you’re seriously trying to drive employees’ well-being, then it has to be about working practices.”

Believers in conspiracy theories are more prone to taking alternative medicines

Vladimir Hedrih
PsyPost
December 12, 2023

New research conducted in France has found that people with more pronounced conspiracy beliefs showed lower intentions to take conventional medicines and higher intentions to take alternative medicines. Individuals with stronger beliefs in generic conspiracy theories also held stronger conspiracy beliefs specifically related to chemotherapy. The study was published in the British Journal of Health Psychology.

Conspiracy beliefs are defined as attempts to explain ultimate causes of significant political and social events with claims of secret plots, collusion, or manipulation by powerful individuals or other entities. These explanations may or may not be true. Conspiracy beliefs often arise in response to perceived inconsistencies, uncertainties, or distrust in official narratives, typically regarding events that represent a threat to the individual.

People who hold conspiracy beliefs may be motivated by a desire to make sense of complex events, regain a sense of control, or express skepticism toward authorities. Conspiracy beliefs can encompass a wide range of subjects, including politics, science, health, and social issues. While some conspiracy beliefs may be rooted in genuine concerns or unanswered questions, others may lack substantial evidence and contribute to the spread of misinformation. Studies indicate that individuals endorsing specific conspiracy beliefs also tend to endorse other conspiracy beliefs, reflecting a generalized conspiracy mindset.

As health is an important topic for most people, many conspiracy beliefs revolve around health issues. For example, the recent COVID-19 pandemic proved to be a very fruitful ground for the development of various conspiracy beliefs, ranging from beliefs about powerful entities hiding effective medicines, or inventing the pandemic itself, to various beliefs about secret sinister plans behind vaccination.

Study authors Valentyn Fournier and Florent Varet wanted to explore the links between generic and specific conspiracy beliefs and intentions to use conventional or complementary and alternative medicines. They hypothesized that the general tendency to endorse conspiracy beliefs will make individuals more likely to endorse specific conspiracy beliefs about chemotherapy. These authors also expected that individuals endorsing conspiracy beliefs would be less willing to use conventional medicine, but more willing to use alternative and complementary medicine. They conducted two surveys.

The first study examined the link between generic and specific chemotherapy-related conspiracy beliefs and their links with the intention to use conventional or alternative medicines. Participants were 291 French adults recruited through social media. They completed assessments of generic conspiracy beliefs (the Generic Conspiracy Belief Scale), chemotherapy-related conspiracy beliefs (created by authors), and intention to use conventional and complementary and alternative medicines (one item for each type of medicine).

The second study replicated the first one with certain changes in how conspiracy beliefs were assessed. Study authors divided conspiracy beliefs into upward and downwards conspiracy beliefs depending on the status of the group behind the conspiracy. Upward conspiracy beliefs are beliefs that organizers of the conspiracies are powerful groups (e.g. governments, big companies), while downward conspiracy beliefs attribute conspiracies to powerless groups (e.g. immigrants, LGBT+). Study participants were 346 French adults recruited through social media.

The results of the first study confirmed the authors’ expectation – there was a very strong association between generic conspiracy beliefs and conspiracy beliefs that were specifically about chemotherapy. Participants with more pronounced generic conspiracy beliefs and chemotherapy-specific conspiracy beliefs tended to declare lower intent to use conventional medicine and higher intent to use alternative medicine. They were also more prone to using complementary medicine, but this association was weaker.

The researchers tested a statistical model suggesting that generic conspiracy beliefs give rise to chemotherapy-specific conspiracy beliefs, which then influence the intentions to use conventional or alternative medicines. The results substantiated the feasibility of this model, confirming the interrelationships among these factors.

The results of the second study confirmed the results of the first. Upward and downward conspiracy beliefs had the same relationships with intention to use alternative and conventional treatments as generic conspiracy beliefs. However, the associations were weaker and the association between downward conspiracy beliefs and the intent to use conventional medicine was too weak to be generalized outside the study sample (was not statistically significant).

“This work shows promising results for the investigation of the links between generic conspiracy beliefs, chemotherapy-related conspiracy beliefs and the intention to use conventional medicine and/or complementary/alternative medicine in an oncology setting. It has shown that generic conspiracy beliefs were strongly related to chemotherapy-related conspiracy beliefs and that both were linked with the intention to use conventional medicine and/or complementary/alternative medicine in two vignette studies,” the study authors concluded.

The study sheds light on links between conspiracy beliefs and medication intentions. However, it should be noted that the design of these studies does not allow any cause-and-effect inferences to be drawn from the results. Additionally, the study survey asked about beliefs and behaviors related to cancer, while none of the survey participants suffered from cancer.

The paper, “Conspiracy beliefs and intention to use conventional, complementary and alternative medicines: Two vignette studies”, was authored by Valentyn Fournier and Florent Varet.

Social isolation linked to changes in brain structure and lower cognition ability

Social isolation linked to changes in brain structure and lower cognition ability

Why do we get a buzz from being in large groups at festivals, jubilees and other public events? According to the social brain hypothesis, it’s because the human brain specifically evolved to support social interactions. Studies have shown that belonging to a group can lead to improved wellbeing and increased satisfaction with life.

Unfortunately though, many people are lonely or socially isolated. And if the human brain really did evolve for social interaction, we should expect this to affect it significantly. Our recent study, published in Neurology, shows that social isolation is linked to changes in brain structure and cognition – the mental process of acquiring knowledge – it even carries an increased risk of dementia in older adults.

There’s already a lot of evidence in support of the social brain hypothesis. One study mapped the brain regions associated with social interaction in approximately 7,000 people. It showed that brain regions consistently involved in diverse social interactions are strongly linked to networks that support cognition, including the default mode network (which is active when we are not focusing on the outside world), the salience network (which helps us select what we pay attention to), the subcortical network (involved in memory, emotion and motivation) and the central executive network (which enables us to regulate our emotions).

We wanted to look more closely at how social isolation affects grey matter – brain regions in the outer layer of the brain, consisting of neurons. We, therefore, investigated data from nearly 500,000 people from the UK Biobank, with a mean age of 57. People were classified as socially isolated if they were living alone, had social contact less than monthly and participated in social activities less than weekly.

Our study also included neuroimaging (MRI) data from approximately 32,000 people. This showed that socially isolated people had poorer cognition, including in memory and reaction time, and lower volume of grey matter in many parts of the brain. These areas included the temporal region (which processes sounds and helps encode memory), the frontal lobe (which is involved in attention, planning and complex cognitive tasks) and the hippocampus – a key area involved in learning and memory, which is typically disrupted early in Alzheimer’s disease.

We also found a link between the lower grey matter volumes and specific genetic processes that are involved in Alzheimer’s disease.

There were follow-ups with participants 12 years later. This showed that those who were socially isolated, but not lonely, had a 26% increased risk of dementia.

Underlying processes

Social isolation needs to be examined in more detail in future studies to determine the exact mechanisms behind its profound effects on our brains. But it is clear that, if you are isolated, you may be suffering from chronic stress. This in turn has a major impact on your brain, and also on your physical health.

Another factor may be that if we don’t use certain brain areas, we lose some of their function. A study with taxi drivers showed that the more they memorised routes and addresses, the more the volume of the hippocampus increased. It is possible that if we don’t regularly engage in social discussion, for example, our use of language and other cognitive processes, such as attention and memory, will diminish.

This may affect our ability to do many complex cognitive tasks – memory and attention are crucial to complex cognitive thinking in general.

Tackling loneliness

We know that a strong set of thinking abilities throughout life, called “cognitive reserve”, can be built up through keeping your brain active. A good way to do this is by learning new things, such as another language or a musical instrument. Cognitive reserve has been shown to ameliorate the course and severity of ageing. For example, it can protect against a number of illnesses or mental health disorders, including forms of dementia, schizophrenia and depression, especially following traumatic brain injury.

There are also lifestyle elements that can improve your cognition and wellbeing, which include a healthy diet and exercise. For Alzheimer’s disease, there are a few pharmacological treatments, but the efficacy of these need to be improved and side effects need to be reduced. There is hope that in the future there will be better treatments for ageing and dementia. One avenue of inquiry in this regard is exogenous ketones – an alternative energy source to glucose – which can be ingested via nutritional supplements.

But as our study shows, tackling social isolation could also help, particularly in old age. Health authorities should do more to check on who is isolated and arrange social activities to help them.

When people are not in a position to interact in person, technology may provide a substitute. However, this may be more applicable to younger generations who are familiar with using technology to communicate. But with training, it may also be effective in reducing social isolation in older adults.

Social interaction is hugely important. One study found that the size of our social group is actually associated with the volume of the orbitofrontal cortex (involved in social cognition and emotion).

But how many friends do we need? Researchers often refer to “Dunbar’s number” to describe the size of social groups, finding that we are not able to maintain more than 150 relationships and only typically manage five close relationships. However, there are some reports which suggest a lack of empirical evidence surrounding Dunbar’s number and further research into the optimal size of social groups is required.

It is hard to argue with the fact that humans are social animals and gain enjoyment from connecting with others, whatever age we are. But, as we are increasingly uncovering, it also crucial for the health of our cognition.

Inventing Conflicts of Interest: A History of Tobacco Industry Tactics

American Journal of Public Health
American Public Health Association
Allan M. Brandt, PhD

Abstract
Confronted by compelling peer-reviewed scientific evidence of the harms of smoking, the tobacco industry, beginning in the 1950s, used sophisticated public relations approaches to undermine and distort the emerging science.

The industry campaign worked to create a scientific controversy through a program that depended on the creation of industry–academic conflicts of interest. This strategy of producing scientific uncertainty undercut public health efforts and regulatory interventions designed to reduce the harms of smoking.

A number of industries have subsequently followed this approach to disrupting normative science. Claims of scientific uncertainty and lack of proof also lead to the assertion of individual responsibility for industrially produced health risks.

ANY SYSTEMATIC INVESTIGATION of the modern relationship of medicine and science to industry must consider what has become the epiphenomenal case of the tobacco industry as it confronted new medical knowledge about the risk of cigarette smoking in the mid-20th century. This, of course, is not to argue that the approach and strategy undertaken by big tobacco are necessarily typical of conventional industry–science relationships. But the steps the industry took as it fashioned a new relationship with the scientific enterprise have become a powerful and influential model for the exertion of commercial interests within science and medicine since that time.

As a result, industrial influence on scientific research and outcome has been a powerful legacy of the tobacco story. In this sense, the tobacco industry invented the modern problem of conflicts of interest at midcentury.1 Before that time, there had been a widespread perception, both within science and among the public, that scientific endeavors constituted a set of activities that were in large measure insulated from “interests.” Institutions have struggled over recent decades to discern new policies and approaches to mitigate the increasingly powerful influence of industries as they affect scientific investigation and the public good.2

THE TOBACCO INDUSTRY IN CRISIS MODE
By late 1953, the tobacco industry faced a crisis of cataclysmic proportions. Smoking had been categorically linked to the dramatic rise of lung cancer. Although health concerns about smoking had been raised for decades, by the early 1950s there was a powerful expansion and consolidation of scientific methods and findings that demonstrated that smoking caused lung disease as well as other serious respiratory and cardiac diseases, leading to death. These findings appeared in major, peer-reviewed medical journals as well as throughout the general media.

As a result, the tobacco industry would launch a new strategy, largely unprecedented in the history of US industry and business: it would work to erode, confuse, and condemn the very science that now threatened to destroy its prized, highly popular, and exclusive product. But this would be no simple matter. After all, in the immediate postwar years—the dawn of the nuclear age—science was in high esteem. The industry could not denigrate the scientific enterprise and still maintain its public credibility, so crucial to its success.

The tobacco industry already had a long history of innovative advertising, marketing, and public relations that had centered on making smoking universal. Starting in the late 19th century, the industry transformed itself to become a model of modern industrial organization and consumer marketing. The industry took a product that had existed at the cultural periphery and remade it into one of the most popular, successful, and widely used items of the early 20th century. The basic tenet of the highly articulated public relations approach the companies deployed centered on the notion that if the current cultural context was inhospitable to the product, one could—through shrewd and creative public relations interventions—change the culture to fit the product.

In the course of this transformation, the tobacco companies successfully defined and exploited critical aspects of a new consumer culture. Within the industry, marketing experts had developed a powerful notion of social engineering, what early public relations theorist Edward Bernays had called the “engineering of consent.”3 According to the logic of this approach, society and culture could be manipulated through public relations to create a marketing environment that favored a particular product, in this instance the cigarette. Individuals’ purchase of a particular product constituted their consent to the underlying meaning-centered campaigns.

It was this approach to “engineering” that would fundamentally inform the industry's approach to the crisis of the 1950s. After all, if public relations could engineer consent among consumers, so too could it manage the science that was now threatening to undermine the tobacco industry's product and the entire industry itself. And yet, as subsequent history would show, the management of culture and social meaning was considerably different from the management of science.

ENGINEERING SCIENCE
The tobacco industry's program to engineer the science relating to the harms caused by cigarettes marked a watershed in the history of the industry. It moved aggressively into a new domain, the production of scientific knowledge, not for purposes of research and development but, rather, to undo what was now known: that cigarette smoking caused lethal disease. If science had historically been dedicated to the making of new facts, the industry campaign now sought to develop specific strategies to “unmake” a scientific fact.4,5

Such a campaign required new tactics and strategies.6,7 The goal was to disrupt the normative processes of knowledge production in medicine, science, and public health. In the conduct of this public relations campaign, the tobacco industry would markedly alter the historical trajectory of industry–science relationships. Although medicine and science had never been sacrosanct from a range of social and commercial interests,8–11 the tobacco industry campaign crossed into new terrain to build a powerful network of interests and influence.

Today, as a result of litigation, journalistic exposure, and historical investigation, this story is relatively well known.3,12–15 Here I deploy what we know about the tobacco industry science program to suggest why and how it would become so influential after its development. Indeed, the tobacco industry constructed a program that had a number of effects within the broader culture of science, knowledge, and policy. For this reason I make the somewhat provocative claim that the industry invented the modern conflicts of interest that now are the subject of such intensive contention in the world of science and medicine as well as media, politics, law, and policy.

The industry well understood the power of interests and the levers of influence. Indeed, the ability to use interests and influence had been key aspects of its past success. Early-20th-century tobacco advertisements centered on the endorsement of public figures of influence and authority who would help to bring smoking into the mainstream. In this respect, the tobacco industry played an important role in constructing a culture of celebrities who would help influence social mores and consumer spending through brand endorsements.3 Although the industry brought extensive experience to the manipulation of culture, its public efforts to control tobacco science had been relatively limited and mostly promotional.

INDUSTRY RESPONSE TO EMERGING TOBACCO SCIENCE
By the early 1950s, the emerging science on tobacco's harms documented in the elite peer-reviewed literature, especially the causal linkage to lung cancer, threatened to undo more than a half century of unprecedented corporate success. With considerable anxiety and rancor within the tobacco industry, the industry's highly competitive CEOs came together in December 1953 at the Plaza Hotel in New York City to map a strategy. They realized that the threat they now faced was unprecedented and would require new, collaborative approaches and expertise. Not surprisingly, given their history, they turned again to the field of public relations that had served them so well in the past. They called upon John W. Hill, the president of the nation's leading public relations firm, Hill & Knowlton.

The public confidence the industry required could not be achieved through advertising, which was self-interested by definition. It would be crucial for the industry to assert its authority over the scientific domain; science had the distinct advantage of its reputation for disinterestedness.16 Hill shared with his public relations predecessor Bernays a deep skepticism about the role of advertising in influencing public perceptions of tobacco. To those schooled in public relations, advertising ran the risk of exposing corporate self-interest. Good public relations relied on scrupulous behind-the-scenes management of media. As Bernays had demonstrated in the 1920s and 1930s, the best public relations work left no fingerprints.3

Hill offered the companies powerful advice and guidance as they faced their crisis. Hill understood that simply denying emerging scientific facts would be a losing game. This would not only smack of self-interest but also ally the companies with ignorance in an age of technological and scientific hegemony. So he proposed seizing and controlling science rather than avoiding it. If science posed the principal—even terminal—threat to the industry, Hill advised that the companies should now associate themselves as great supporters of science. The companies, in his view, should embrace a sophisticated scientific discourse; they should demand more science, not less.

Of critical importance, Hill argued, they should declare the positive value of scientific skepticism of science itself. Knowledge, Hill understood, was hard won and uncertain, and there would always be skeptics. What better strategy than to identify, solicit, support, and amplify the views of skeptics of the causal relationship between smoking and disease? Moreover, the liberal disbursement of tobacco industry research funding to academic scientists could draw new skeptics into the fold. The goal, according to Hill, would be to build and broadcast a major scientific controversy. The public must get the message that the issue of the health effects of smoking remains an open question. Doubt, uncertainty, and the truism that there is more to know would become the industry's collective new mantra.

Hill was above all a cynic, deeply committed to the instrumental ideals of public relations. He was profoundly confident that public relations strategies, well developed and implemented, could effectively serve the needs of his clients. He believed—and he convinced the companies’ leadership—that by calling for more research and offering funding, they could take high ground in their public pronouncements. Although he had quit smoking himself, he had no interest in examining and assessing the data or the emerging science. For Hill, science would be a means to a public relations end. The executives of the 5 major companies endorsed his strategic plan and hired Hill & Knowlton to manage their burgeoning corporate crisis.

THE TOBACCO INDUSTRY RESEARCH COMMITTEE
Hill and his colleagues set to work to review the full range of approaches open to them. Dismissing as shortsighted the idea of mounting personal attacks on researchers or simply issuing blanket assurances of safety, they concluded instead that seizing control of the science of tobacco and health would be essential to seizing control of the media. Although public relations practitioners had considerable experience manipulating the media, what was radical about Hill's proposed strategy was the desire to manipulate scientific research, debate, and outcomes. It would be crucial to identify scientists who expressed skepticism about the link between cigarettes and cancer, those critical of statistical methods, and especially those who had offered alternative hypotheses for the causes of cancer.

Hill set his staff to identifying the most vocal and visible skeptics of the emerging science of smoking and disease. These scientists (many of whom turned out to be smokers themselves) would be central to the development of an industry scientific program in step with larger public relations goals. Hill understood that simply denying the harms of smoking would alienate the public. His strategy for ending what the tobacco CEOs called the hysteria linking smoking to cancer was to insist that there were 2 sides in a highly contentious scientific debate. Just as Bernays had worked to engineer consent, so Hill would engineer controversy. This strategy—invented by Hill in the context of his work for the tobacco industry—would ultimately become the cornerstone of a large range of efforts to distort scientific process for commercial ends during the second half of the 20th century.3,6,7

Individual tobacco companies had sought to compile information that cast doubt on the smoking–cancer connection even before Hill & Knowlton became involved. One R.J. Reynolds official announced to other industry executives in November 1953 that the company had formed a bureau of scientific information to “combat the propaganda which is being directed at the tobacco industry.”17 At the same time, American Tobacco began to collect the public statements of scientists who had expressed skepticism about the research findings indicting tobacco. The company's own public relations counsel understood that it would be critical to create questions about the reliability of the new findings and to attack the notion that these studies constituted proof of the relationship of smoking to cancer.18

Pooling these efforts, Hill & Knowlton produced a compendium of statements by physicians and scientists who questioned the cigarette–lung cancer link. This compendium became a fundamental component of Hill & Knowlton's initial attempts to shape and implement its public relations strategy.

After the December 15 meeting that formally brought Hill & Knowlton into the picture, its executives spent the next 2 weeks meeting with various industry staff. During this time, Hill & Knowlton operated in full crisis mode. Executives and staff canceled all holiday plans as they worked to frame and implement a full-scale campaign on behalf of the industry.19,20 They made no independent attempt to assess the state of medical knowledge, nor did they seek informed evaluations from independent scientists. Their role was exclusively limited to serving the public relations goal of their collective clients.

During these meetings, both Hill & Knowlton staffers and tobacco executives continued to voice the conviction that the industry's entire future was threatened by the medical and scientific findings linking cigarette smoking to lung cancer and the consequent widespread public anxieties about smoking and health.

Because of the serious nature of the attack on cigarettes and the vast publicity given them in the daily press and in magazines of the widest circulation, a hysteria of fear appears to be developing throughout the country,

Hill wrote in an internal memorandum. “There is no evidence that this adverse publicity is abating or will soon abate.” According to his media intelligence, at least 4 major periodicals (Look Magazine, Cosmopolitan, Woman's Home Companion, and Pageant) were planning articles on smoking and health.21a

It was Hill who hit on the idea of creating an industry-sponsored research entity. Ultimately, he concluded, the best public relations approach was for the industry to become a major sponsor of medical research.21b This tactic offered several essential advantages. The call for new research implied that existing studies were inadequate or flawed. It made clear that there was more to know, and it made the industry seem a committed participant in the scientific enterprise rather than a self-interested critic.

The industry had supported some individual research in recent years, but Hill's proposal offered the potential of a research program that would be controlled by the industry yet promoted as independent. This was a public relations masterstroke. Hill understood that simply giving money to scientists—through the National Institutes of Health or some other entity, for example—offered little opportunity to shape the public relations environment. However, offering funds directly to university-based scientists would enlist their support and dependence. Moreover, it would have the added benefit of making academic institutions “partners” with the tobacco industry in its moment of crisis.

The very nature of controlling and managing information in public relations stood in marked contrast to the scientific notion of unfettered new knowledge. Hill and his clients had no interest in answering a scientific question. Their goal was to maintain vigorous control over the research program, to use science in the service of public relations. Although the tobacco executives had proposed forming a cigarette information committee dedicated to defending smoking against the medical findings, Hill argued aggressively for adding research to the committee's title and agenda. “It is believed,” he wrote, “that the word ‘Research’ is needed in the name to give weight and added credence to the Committee's statements.”21a Hill understood that his clients should be viewed as embracing science rather than dismissing it.

Hill also advised the industry that continued competitive assertions about the health benefits of particular brands would be devastating. Instead, the industry needed a collective research initiative to demonstrate its shared concern for the public. Rather than using health research to create competitive products as they had been doing, the companies needed to express—above all else—their commitment to public well-being. Hill believed that the competitive fervor over health claims had harmed the industry's credibility. No one would look for serious information about health from an industry that was making unsubstantiated claims about its product.

The future of the industry would reflect its acceptance of this essential principle. From December 1953 forward, the tobacco companies would present a unified front on smoking and health; more than 5 decades of strategic and explicit collusion would follow.22 The Tobacco Industry Research Committee (TIRC), a group that would be carefully shaped by Hill & Knowlton to serve the industry's collective interests, would be central to the explicit goal of controlling the scientific discourse about smoking and health. The public announcement of the formation of the committee came in a full-page advertisement run in more than 400 newspapers across the country, soon known as the “frank statement.” The ad promised that the companies would aggressively pursue the science of tobacco and ensure the well-being of their consumers:

We accept an interest in people's health as a basic responsibility, paramount to every other consideration in our business. We believe the products we make are not injurious to health. We always have and always will cooperate closely with those whose task it is to safeguard the public health.23

The frank statement remains a powerful illustration of how Hill was prepared to use science in the interest of his clients. It is a model of the “new” public relations that he established at midcentury.

Hill carefully outlined the plans for a research program before a single scientist was consulted. The utility of such a strategy was its apparent commitment to objective science and its search for the truth. As one colleague argued,

A flamboyant campaign against the anti-smoking propagandists would unquestionably alienate much of the support of the moderates in both scientific and lay publics.”24

Instead, tobacco companies had to respect the moral valence of science in American culture at midcentury. If science now threatened the industry, the industry must “secure” science.

The TIRC, from its inception, was dominated by its public relations goals. Alton Ochsner, the well-known thoracic surgeon who had conducted research on the relationship of smoking to heart disease, saw his own hopes for funding support from the industry fade as the TIRC's research agenda quickly became clear. He noted,

Of course, the critical areas of investigation, as every research scientist knows, have to do with the problem of how to make smoking a less lethal agent in lung cancer incidence and a less deadly killer in heart disease… . Yet it is precisely these areas that apparently have been declared out of bounds for the industry's research committee.25(p72)

Internal industry assessments confirmed Ochsner's view. As one internal industry evaluation would conclude a decade later, “most of the TIRC research has been of a broad, basic nature not designed to specifically test the anti-cigarette theory.”26 From the outset, Hill & Knowlton exerted full control over the industry's collaborative research program. The TIRC administrative offices were even located at Hill & Knowlton's New York office. W.T. Hoyt, executive director of the TIRC, came to the position with no scientific experience whatsoever. Before joining Hill & Knowlton, he sold advertising for the Saturday Evening Post. At Hill & Knowlton, where he began work in 1951, he had run the iron and steel industry's Scrap Mobilization Committee. In early 1954, he assumed a dominant role in the day-to-day operations of the tobacco industry research program. Ultimately, Hoyt would become a full-time employee, remaining integral to the TIRC until he retired in 1984.27

Tobacco company leaders also played important roles in the organization. In the early months of operation, Paul Hahn of American Tobacco and Parker McComas of Philip Morris served as its acting chairs. The first full-time chairman of TIRC was Timothy Hartnett, the retired CEO of Brown & Williamson. The press release announcing his appointment read, in part, as follows:

It is an obligation of the Tobacco Industry Research Committee at this time to remind the public of these essential points:

1. There is no conclusive scientific proof of a link between smoking and cancer.

2. Medical research points to many possible causes of cancer… .

5. The millions of people who derive pleasure and satisfaction from smoking can be reassured that every scientific means will be used to get all the facts as soon as possible.28

Hartnett and his successors would reiterate this message for the next 40 years.

The first scientific director of the TIRC was noted biologist, geneticist, and eugenicist Clarence Cook Little. Little came to the position as an aggressive and uncompromising skeptic of the epidemiological work that had demonstrated the relationship of smoking to lung cancer. He had strong a priori views that cancer must be essentially genetic and that ultimately this would be demonstrated. Given his scientific pedigree, national standing, and propensity for public conflict, he was extremely well chosen from a public relations perspective. Although Little favored basic science investigations into the mechanism of cancer, often using animal models, he never confronted the critical issue of the relationship of translating such research from the laboratory to humans.3

Cancer researchers reacted to Little's appointment as scientific director of the TIRC with surprise and distaste. “You may be surprised to know that Dr. C. C. Little was willing to become the chairman of that Committee,” noted Evarts Graham, a leading American thoracic surgeon in a 1956 letter to A. Bradford Hill, whose research had been crucial to linking smoking to lung cancer.

It seems astonishing to me that a man of his eminence in the field of cancer and genetics would condescend to take a position like that.”29

Graham went on to express his frustration with Little's persistent skepticism in the face of mounting scientific evidence. “Isn't the evidence at hand sufficient to convince anybody with an open mind?” asked Graham.

When the TIRC had announced its first set of grants almost 2 years earlier in November 1954, Ochsner called the TIRC program “tapeworm research into the physical and chemical composition of tobacco.” According to Ochsner, the industry “sought to postpone a day of reckoning for the irresponsible advertising and sale of its products.”30(p23) The industry had demonstrated the power of its influence over science in its ability to secure Little to lead its program. Blurring the boundaries between industrial public relations and academic science was critical to the industry's interests.

SECURING ACADEMIC SUPPORT
In 1954, the committee's first year of operation, the TIRC budget approached $1 million, almost all of which went to Hill & Knowlton, media ads, and administrative costs. Funding for the grant program increased substantially in later years, reaching $800 000 by 1963. Under Little's leadership and with the meticulous interventions of the Hill & Knowlton team, the Scientific Advisory Board (SAB), made up mostly of academic researchers, conducted peer reviews of grant proposals after they had been carefully screened by the staff. The SAB had been hand-picked by Hill & Knowlton, which was always on the lookout for skeptics (and, even better, skeptics who smoked).

The TIRC settled into a program of funding research principally on the basic science of cancer, with little or no relevance to the critical questions associated with the medical risks of smoking. Most of the TIRC's program centered on basic questions in immunology, genetics, cell biology, pharmacology, and virology. This focus apparently suited all concerned. It was certainly ideal from a public relations standpoint because research unrelated to smoking would not condemn cigarettes. SAB members could assert that they were offering valuable resources to important scientific questions yet distance themselves from the specific question of the harms of tobacco and thus avoid accusations of bias.

SAB members frequently told the TIRC staff that they did not wish to be associated with the TIRC's frequent public statements about smoking and health. They were generally skeptical or agnostic concerning the harms of smoking but believed that their direct association with the frequent TIRC statements asserting “no proof ” would make them appear ignorant, prejudiced, and partisan.3

In February 1958, a number of SAB members communicated that they were “disturbed by a misunderstanding of the relationship between the TIRC and the SAB.” Several board members expressed concern about the public statements of the TIRC. Physiologist Julius Comroe apparently threatened to resign because he and other SAB members had been placed in the “awkward position of unwittingly endorsing everything that the TIRC said.” Leon Jacobson of the University of Chicago, another SAB member, echoed this worry and, according to the minutes of the meeting, explained that “he did not wish to be linked with any of the statements made by the TIRC.”31

Although the founding members of the SAB would steadfastly defend their independence from the industry, the reality is that under the Hill & Knowlton plan, they had been manipulated for effective public relations, a fact they periodically acknowledged with some bitterness.32 Indeed, the very structures of scientific advisory boards—now ubiquitous in industry–science activities—were largely the invention of the tobacco industry under Hill's careful guidance. The SAB cemented the relationship between academic researchers and industrial interests.

By steering funds away from the effects of tobacco toward basic science in cancer, the TIRC avoided the implication that it served industry interests. SAB members were frequently in a position to secure funding from the industry to support the work of colleagues and associates, as well as other research at their home institutions. Such arrangements gave them considerable influence and clearly sustained their loyalty to the TIRC. As Hill anticipated, researchers associated with the TIRC typically avoided taking any position on the tobacco controversy. The companies had effectively “chilled” a major scientific and public health finding through the distribution of research funding. At the same time, the funds provided by the TIRC had purchased both entrée and legitimacy for the industry within the academic science community.

Little and his Hill & Knowlton colleagues constructed a basic science research program into aspects of carcinogenesis that had no potential to resolve the question that the tobacco industry had promised the American public would be at the center of attention: do cigarettes cause serious disease? Little became the industry's primary spokesman in obscuring this question. The sharp disjuncture between the research agenda of the TIRC and the commitment to resolving the controversy about smoking and health is a major indicator of the committee's essential public relations goals. In the end, the TIRC was designed to direct attention away from the issue of immediate concern to the American public and American medicine: the health effects of smoking.

In this way, the tobacco industry managed to sustain the widespread perception of an active and highly contested scientific controversy into the 1960s despite overwhelming evidence and scientific consensus that smoking caused serious disease. According to the TIRC, many independent and responsible scientists continued to voice opposition to these findings. In reality, over the course of the decade, such views were increasingly marginal and limited to those with financial ties to the TIRC.

But skepticism does not indicate that there is not consensus. With each passing year, skepticism concerning the relationship between smoking and cancer was increasingly dominated by industry resources and public media. Doubt was no longer a matter of culture or training but the carefully crafted centerpiece of an industry effort to sow confusion and heighten debate through explicit attempts to disrupt the process of normative science. The TIRC marks one of the most intensive efforts by an industry to derail independent science in modern history. And, as shown subsequently, others would follow the tobacco industry's road map, drawn in the 1950s.33

In 1974, Alexander Spears, then director of research and development at Lorillard (he became CEO and chairman in 1995), offered this assessment:

Historically, the joint industry funded smoking and health research programs have not been selected against specific scientific goals, but rather for various purposes such as public relations, political relations, position for litigation, etc. Thus, it seems obvious that reviews of such programs for scientific relevance and merit in the smoking and health field are not likely to produce high ratings. In general, these programs have provided some buffer to the public and political attack of the industry, as well as background for litigious strategy.34

The industry–science connection was the foundation of Hill's public relations architecture; it was crucial to the ability of the industry to influence the media, public opinion, policy, regulation, and the law.

THE MEDIA
At the same time that Hill and his colleagues were establishing the TIRC, they worked aggressively to reshape the media environment. Hill & Knowlton's public relations strategy relied on intensive contact with authors, editors, scientists, and opinion makers. Hill understood that the success of any public relations strategy was highly dependent on face-to-face interpersonal relations with important media outlets. Each time the TIRC issued a press release, the Hill & Knowlton organization would initiate a “personal contact.” The firm systematically documented the courtship of newspapers and magazines wherein it could urge balance and fairness to the industry.

In these entreaties on behalf of the industry, the firm's staffers repeated several key themes. First, they would note that the industry completely understood its important public responsibilities. Second, they would affirm that the industry was deeply committed to investigating all of the scientific questions relevant to resolving the controversy. Third, they urged skepticism regarding statistical studies. Finally, they offered members of the media a long list of “independent” skeptics to consult to ensure balance in their presentations.3

The primary independent skeptic, of course, was the TIRC's Little. Given the penchant of the press for controversy and its often naive notion of balance, these appeals were remarkably successful. Hill & Knowlton expertly broadcast the arguments (typically not based on substantive research of any kind) of a small group of skeptics as if their positions represented a dominant perspective on the medical science of the cigarette. In this sense, the public relations campaign advantaged 2 critical aspects of midcentury media practice. First, journalists favored reporting on controversy. Second, by providing opposing positions (as if they were equal) they affirmed their commitment to balance.

The problem in this formulation was that science was treated as the analog of common political debate and social controversy. At that time, few journalists had any sophisticated scientific education or training. By fashioning a controversy, Hill & Knowlton successfully secured media coverage that maintained, by its very nature, that tobacco science was “unresolved.”35

Another strategy deployed throughout the 1950s by the firm was to learn about new scientific findings and consensus reports and to be ready to attack when they were released. The agency took pride in its extensive network of scientific informants. At its headquarters in New York, the TIRC developed a large, systematically cross-referenced library on all issues tobacco related. As one Hill & Knowlton executive explained:

One policy that we have long followed is to let no major unwarranted attack go unanswered. And that we would make every effort to have an answer in the same day—not the next day or the next edition. This calls for knowing what is going to come out both in publications and in meetings.36

In many instances, the TIRC offered a rebuttal of new findings even before they had become available. They could be so nimble because they aggressively solicited a small group of doubters and broadcast their misgivings as if they were based on rigorous and systematic research. So long as skepticism survived (and of course it would), the industry possessed the basis for its aggressive defense. By 1962, after nearly a decade of work, Hill & Knowlton was eager to be able to explicitly demonstrate the impact of its interventions on its client's behalf.

Now—can we, from this experience, answer this fundamental public relations question: Is such preparation and effort for simultaneous comment on attacks on your client worth the effort it requires?

We say the answer is unequivocally yes!

Proof? Well, how do you prove it?

From time to time, man-on-the-street interviews ask about the smoking question. In almost every one of these, there will be a quotation that is almost an exact paraphrase of some statement issued for the tobacco accounts.36

INDUSTRIAL BENEFITS OF SCIENTIFIC UNCERTAINTY
Hill & Knowlton had successfully produced uncertainty in the face of a powerful scientific consensus. So long as this uncertainty could be maintained, so long as the industry could claim “not proven,” it would be positioned to fight any attempts to assert regulatory authority over the industry. Without their claims of no proof and doubt, the companies would be highly vulnerable in 2 crucial venues: regulatory politics and litigation.37

John Hill thus advised the establishment of another unit, separate from the TIRC, that would explicitly act as a trade association and lobby for the industry's growing political and public relations needs. After all, the TIRC had been explicitly developed to sustain claims of independence, commitment to science, and pursuit of the “truth” about tobacco. Its credibility and influence rested on perceptions of restraint and a narrow scientific mission. As noted, the scientists Hill & Knowlton had recruited to serve on the SAB had expressed repeated concerns about the board's independence and their personal credibility among scientific peers. In the words of an industry attorney,

the creation of a separate organization for public information was hit upon as a way of keeping Little inviolate and untainted in his ivory tower while giving a new group a little more freedom of action in the public relations field.26

This approach would protect the public relations capital invested in the TIRC while creating an unencumbered unit that could engage in both political lobbying and a more aggressive brand of public relations. Freed of the constraint of the TIRC's scientific mission, Hill & Knowlton worked to create a state-of-the-art political and public relations operation to address the regulatory initiatives on the horizon in the wake of early congressional hearings. After its founding in 1958, the Tobacco Institute quickly emerged as one of Washington's most powerful, well-heeled, and effective political lobbies. Just as the industry had made critical innovations in advertising and public relations, it now pioneered new and aggressive approaches to managing its regulatory and political environment.

In 1964, using a combination of skills, resources, and Washington insiders, the Tobacco Institute assiduously prepared for the political fights that would follow in the wake of the first surgeon general's report on smoking and health. The institute anticipated that the ground on which the tobacco wars were fought would shift, at least in part, from the scientific realm to the political. Certainly, these battles would engage scientific questions, but Congress would be the new primary site of conflict. It was terrain that greatly favored the tobacco industry, with its lobbying largesse and the strong geopolitical interests of tobacco-growing states.

Indeed, looking back at the half-century that followed the path-breaking science clearly linking cigarettes to disease and premature death, it is striking to note the utter lack of serious and effective regulatory action on the part of the federal government. It is also critical to note that the lobbying and public relations efforts of the Tobacco Institute rested fundamentally on the claims of the scientific doubt and uncertainty generated by the TIRC.

LAW
Without regulatory intervention, some smokers turned to the courts for redress. By 1964, more than 30 lawsuits accusing the industry of negligence and other malfeasance had been filed in American courts. Although most had been dismissed or dropped, the risks associated with liability litigation were considered potentially disastrous. Again, the efforts of the Hill campaign were used on behalf of the legal program of the companies. The SAB and other physicians and scientists identified by the TIRC, including C.C. Little himself, were frequently deployed as expert witnesses in the industry's uniformly effective legal defenses in civil litigation. Defending such litigation required that the companies continue to rely on the no-proof strategy. According to 2 British tobacco executives38:

In consequence of the importance of the lawsuits, the main power in the smoking and health situation undoubtedly rests with the lawyers….The leadership in the U.S. smoking and health situation therefore lies with the powerful Policy Committee of senior lawyers advising the industry, and their policy, very understandably, in effect is “ don't take any chances.” It is a situation that does not encourage constructive or bold approaches to smoking and health problems, and it also means that the Policy Committee of lawyers exercises close control over all aspects of the problems.38

After the 1964 surgeon general's report, even as some industry executives (including lawyers) offered proposals for modifying the decade-old “not proven” claim, the Policy Committee strongly resisted any deviation from this traditional position, which it deemed crucial to an effective defense against liability actions. The committee feared that any discussion of modifying the product or openly researching its biologically active properties could be viewed in the courts as an “implied admission” that the manufacturer knew the product was harmful.38

Any move away from an agnostic public posture could, it was argued, lead to high-risk litigation. Even as the industry's insistence on a continuing controversy became increasingly untenable from a scientific and public relations perspective, the companies remained wedded to it for legal reasons.39,40 This dilemma would shape tobacco politics into the 21st century.

THE CHILLING EFFECTS OF INDUSTRY FUNDING
In their work to control the science, the companies had also found that they had secured considerable advantages in the realms of media, law, and public opinion. All of this was dependent on maintaining the notions of controversy, uncertainty, and doubt. In 1961, Hill & Knowlton celebrated its successes on behalf of its tobacco client. The total number of cigarettes sold annually had risen from 369 billion in 1954, the company's first full year of service to the industry, to 488 billion. Per capita consumption had risen from 3344 a year in 1954 to 4025 in 1961, the highest ever. “From a business standpoint,” Hill & Knowlton crowed, “the tobacco industry has weathered this latest spate of health attacks on its products.”36

In less than a decade, the industry had been stabilized and was thriving. As noted journalist Joseph Lelyveld concluded in the New York Times,

Surprisingly, the furor over smoking and health failed to send the industry into a slump. Instead, it sent it into an upheaval that has resulted in unforeseen growth and profits.

He went on to quote an unnamed American Cancer Society official who claimed,

When the tobacco companies say they're eager to find out the truth, they want you to think the truth isn't known…. They want to be able to call it a controversy.41(p59)

The TIRC, under Hill & Knowlton's guidance, had turned tobacco science into yet one more political controversy on which people could differ. So long as it could maintain this “liberal” notion of scientific knowledge, the industry remained free to promote tobacco use aggressively without regulation or liability. This explains, in part, why the industry would so tenaciously cling to the notion of scientific controversy.

CONCLUSIONS
By the early 1960s—despite categorical research findings indicating the harms of smoking—a significant “controversy” had arisen (at the behest of the tobacco industry) over the validity and meaning of these findings. Indeed, given the widespread acceptance of the conclusion, especially among those who had analyzed and evaluated the research most closely, the persistence of debate about the harms of smoking is a striking demonstration of the powerful impact of the tobacco industry's public relations campaign. The industry insistence, at the direction of Hill & Knowlton, on the notion of no proof and the need for more research was an inspired if cynical manipulation of the natural tendencies within science to encourage skepticism and seek more complete answers to important questions.

Hill & Knowlton had served its tobacco clients with commitment and fidelity and with great success. But the firm had also taken its clients across a critical moral barrier that would have 2 important effects on American science and society. Trust in science, confidence in the media, and the social responsibility of the corporate enterprise were all substantially harmed by Hill & Knowlton's efforts on behalf of the tobacco industry. By making science fair game in the battle of public relations, the tobacco industry set a destructive precedent that would affect future debates on subjects ranging from global warming to food and pharmaceuticals.33 In addition, by insinuating itself so significantly into the practice of journalism, Hill & Knowlton compromised the legitimacy and authority of the very instruments upon which public relations depended.

The tobacco industry's public relations campaign permanently changed industry–science relationships and public culture. Their disinformation campaign, built on a foundation of conflicts of interest, demonstrates a series of problems that continue to evolve regarding the relationship between medical science and industrial influence. Indeed, the exposure of this strategy is among the factors that have drawn such suspicion and mistrust to industry-sponsored science since the 1990s. Certainly every industry does not have the attributes and character of big tobacco, deeply committed to continuing to market a deadly product throughout the world. In this sense, tobacco is unique. At the same time, however, the significance of industrial interests in shaping scientific discourse and outcomes remains undeniable.

Conflicts of interest—such as those invented by the tobacco industry—have the potential to undermine and corrupt the scientific enterprise in ways that do significant damage to what we know and how we deploy the knowledge we possess. The impact of the relationships that the industry built and developed during the 1950s (and afterward) were of truly great significance for public health. The industry had bought not only critical time but a new generation of smokers who would succumb to the multiple harms of its product.42 The industry program disrupted normative scientific processes at the same time that it generated new legitimacy and credibility for the companies by associating them with “university-based” science, an irony not lost on John Hill and his corporate clients.

While undermining public health and regulatory intervention, the convention of scientific uncertainty also possessed one other critical advantage for the industry: it served to reify the notion that smoking is an “individual” risk taken on at the discretion of the smoker. If, in fact, it could not be known whether smoking was a serious risk to health, the companies argued that it would be up to consumers to decide whether to smoke in this context. As a result, the companies insisted that any risks associated with their product were now the responsibility of the individual smoker.43

In other words, creating scientific uncertainty permitted the companies to attribute the very risks imposed by their product to individuals rather than to the companies themselves. In this framework, all liabilities would rest with the individual smoker, who now “agreed” to assume all risks that “might” be associated with the product. The companies would repeatedly use this argument to avoid liability in litigation as well as regulation. The presumption of personal responsibility for the harms of smoking has underscored all tobacco promotion and sales since the 1950s. This cultural assumption, which the tobacco industry has aggressively promoted, rests heavily on the Hill & Knowlton scientific campaign of the 1950s. Without a robust notion of scientific uncertainty, such claims would have been impossible.3

The story of the tobacco “controversy” and the industry's deliberative attempts to disrupt science is now, fortunately, fairly well known. In large measure, this story emerged only as a result of whistle blowers and litigation that led to the revelation of millions of pages of internal tobacco documents that both laid out this strategy and documented its implementation.39 But what has often gone overlooked in the assessment of the tobacco episode was the highly articulated, strategic character of seizing the scientific initiative, the engineering of science. This, however, was a factor well understood by John Hill and the public relations teams that advised the companies. They carefully documented what the scientific investment would buy and how best for the companies to protect and defend that investment.

A wide range of other industries have carefully studied the tobacco industry strategy. As a result, they have come to better understand the fundamentals of influence within the sciences and the value of uncertainty and skepticism in deflecting regulation, defending against litigation, and maintaining credibility despite the marketing of products that are known to be harmful to public health. Also, they have come to understand that the invention of scientific controversy undermines notions of the common good by emphasizing individual assessment, responsibility, and judgment.
