3 Things Economics Can’t Solve
Kate Pickett is a Professor of Epidemiology at the University of York and a National Institute for Health Research Career Scientist. She studied physical anthropology at Cambridge, nutritional sciences at Cornell and epidemiology at Berkeley before spending four years as an Assistant Professor at the University of Chicago. Her work, with Richard Wilkinson, on "The Spirit Level" was shortlisted for Research Project of the Year 2009 by the Times Higher Education Supplement, and their book was chosen as one of the Top Ten Books of the Decade, by the New Statesman.
Question: What is the relationship between economic growth and life expectancy?
Kate Pickett: What we find is, in the rich developed market democracies, there’s no longer any relationship between average levels of income in a country and life expectancy. So, you can have a country like the USA, or Norway, that’s twice a rich as another country like Greece for instance, and that doesn’t seem to affect life expectancy at all. And the same is true of happiness. Happiness isn’t related to average levels of income in a country either. Now, that’s not true of the developing world when you don’t have enough, when people are lacking food or shelter, or the basic material necessities. Then economic growth is really important. But in our rich, developed democracies, it no longer makes any difference. So, we seem to have come to an end of what economic growth can do for us in terms of life expectancy, happiness, well-being and that sort of thing.
If you look at the United States, over the past few decades, you’ve become twice, three times a rich as you used to be, levels of happiness haven’t improved at all.
Question: How does social inequality affect our health?
Kate Pickett: I think this is where it helps that Richard Wilkinson, my co-author and I, we’re epidemiologists, and so we study levels of population health. And one thing we really learned over the past 30 years in epidemiology is the importance of psycho-social factors for health. Things like low social status, or social affiliation, social networks, whether or not you have friends, and the stresses of early childhood. All of those things have turned out to be really important for health. And we have quite a good understanding now of the biology of chronic stress. So, all of these things are working as stresses, low social status, lack of friends or social networks, stress in early childhood. And chronic stress affects our biology, our physiology in lots of different ways. It affects our immune system, our hormonal responses, it affects our cardiovascular health. And that’s quite well understood. And so we have also known for a long time that the people at the bottom of society, the poorer people in our societies, people living in the most deprived neighborhoods have much higher levels of stress and much worse health than those who are more affluent or have higher social status.
Question: Is there a threshold for when economic growth stops affecting life expectancy?
Kate Pickett: Yeah, it’s not so much about the threshold, the threshold changes over time. It’s really just seeing that although life expectancy continues to improve over time, that’s not related to average levels of income anymore in the rich countries. Instead, what we find is really important is the level of income and equality that is the gap between the rich and the poor. That’s what seems to matter these days for our health and social well being.
An epidemiologist explains the evidence that life expectancy, happiness, and well-being do not increase with income and national wealth.
Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.
A time for sleep<div class="rm-shortcode" data-media_id="Mt29uUqI" data-player_id="FvQKszTI" data-rm-shortcode-id="931343dee3c02121445e51e94ba22446"> <div id="botr_Mt29uUqI_FvQKszTI_div" class="jwplayer-media" data-jwplayer-video-src="https://content.jwplatform.com/players/Mt29uUqI-FvQKszTI.js"> <img src="https://cdn.jwplayer.com/thumbs/Mt29uUqI-1920.jpg" class="jwplayer-media-preview" /> </div> <script src="https://content.jwplatform.com/players/Mt29uUqI-FvQKszTI.js"></script> </div> <p>Previous studies had already suggested a link between persistent nightmares in childhood and psychosis and borderline personality disorder (BPD) by adolescence, but researchers at the University of Birmingham's School of Psychology wanted to see if a similar connection existed between these mental disorders and other childhood behavioral sleep problems.</p><p>To do this, they scoured data from the Avon Longitudinal Study of Parents and Children, a longitudinal cohort study that followed approximately 14,000 children born in Avon, England, in the early 1990s. The study followed the children for more than 13 years. During that time, mothers filled out questionnaires asking about the children's lives. Factors looked at included housing, parenting, nutrition, physical health, mental wellbeing, environmental exposures, and so on. </p><p>The cohort study inquired about sleep routines, sleep duration, and awakening frequency when the children were 6, 18, and 30 months old, and then again at 3.5, 4.8, and 5.8 years. It also assessed mental health in adolescence using semi-structured interviews, such as the Psychosis-Like Symptom Interview.</p><p>"We know that adolescence is a key developmental period to study the onset of many mental disorders, including psychosis or BPD. This is because of particular brain and hormonal changes which occur at this stage," <a href="https://www.birmingham.ac.uk/staff/profiles/psychology/marwaha-steven.aspx" target="_blank">Steven Marwaha</a>, professor of psychiatry at Birmingham and senior author on the study, <a href="https://www.sciencedaily.com/releases/2020/07/200701125431.htm" target="_blank">said in a release</a>. "Sleep may be one of the most important underlying factors—and it's one that we can influence with effective, early interventions, so it's important that we understand these links."</p><p>After compiling the data, the researchers discovered an association between children with irregular sleeping patterns and teenagers with <a href="https://www.mind.org.uk/information-support/types-of-mental-health-problems/psychosis/about-psychosis/" target="_blank">psychotic experiences</a>—that is, episodes when the person perceives reality differently than those around them. Even when depression at 10 years old was considered as a mediating factor, their findings still suggested "a specific pathway between these childhood sleep problems and adolescent psychotic experiences." </p><p>Toddlers with shorter nighttime sleep duration and late bedtimes were likewise associated with a <a href="https://www.nimh.nih.gov/health/topics/borderline-personality-disorder/index.shtml" target="_blank">borderline personality disorder</a>—a disorder marked by a pattern of varying moods, self-images, and behaviors—in their teenage years. Depression at age 10 did not mediate this particular association, suggesting a separate and more specific pathway. </p>
A more restful tomorrow<p>While the sample size was large and mental health was assessed with a validated interview, there nevertheless remain limitations to this data. For starters, sleep habits were based on mothers' reports. Because they came from memory, versus a more direct observation method such as actigraphy, these data may be prone to imperfect recollection and reporting error. There are also many confounders that could be secretly nudging the results, such as family conditions, prenatal medicines, and a host of environmental factors. Finally, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6024884/#:~:text=Sleep%20difficulties%20in%20youth%20with,fear%20of%20dark%20%5B13%5D." target="_blank">the relationship between sleep problems and mental disorders</a> is both complex and two-way.</p><p>As such, the study shows an association between poor childhood sleep later mental disorders but does not prove a causal link. Parents need not worry that a string of nightmares or the eternal struggle settle into bed will be the first ingredients in a witches' brew of debilitating mental disorders. The goal of the study, the researchers point out, is not to create undue worry but improve our ability to recognize the signs of at-risk children and deliver necessary interventions earlier.</p><p>"The results of this study could have important implications for helping practitioners identify children who might be at higher risk for psychotic experiences or BPD symptoms in adolescence, and potentially lead to the design of more effectively targeted sleep or psychological interventions to prevent the onset or attenuate these mental disorders," Isabel Morales-Muñoz, the study's lead researcher, <a href="https://www.healio.com/news/psychiatry/20200702/childhood-sleep-problems-linked-to-adolescent-psychosis-borderline-personality-disorder#:~:text=Sleep%20problems%20during%20early%20childhood,study%20published%20in%20JAMA%20Psychiatry." target="_blank">told Healio Psychiatry</a><u>.</u></p><p>If a parent reading this is worried that their child's sleep patterns are deleterious, the take away should not be despair over an unyielding fate. It should be to seek professional help as soon as possible to begin improving sleep duration and quality. Even if you aren't worried, it's worth remembering that childhood experiences lay the foundation for a lifetime of salubrious sleeping habits. It's so much more than beauty rest.</p>
Are we genetically inclined for superstition or just fearful of the truth?
- From secret societies to faked moon landings, one thing that humanity seems to have an endless supply of is conspiracy theories. In this compilation, physicist Michio Kaku, science communicator Bill Nye, psychologist Sarah Rose Cavanagh, skeptic Michael Shermer, and actor and playwright John Cameron Mitchell consider the nature of truth and why some groups believe the things they do.
- "I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking," argues Kaku. The theoretical physicist says that science goes against "natural thinking," and that the superstition gene persists because, one out of ten times, it actually worked and saved us.
- Other theories shared include the idea of cognitive dissonance, the dangerous power of fear to inhibit critical thinking, and Hollywood's romanticization of conspiracies. Because conspiracy theories are so diverse and multifaceted, combating them has not been an easy task for science.

COVID-19 and the brain<p>A growing body of research reveals alarming neurological complications among COVID-19 patients. On Wednesday, for example, researchers from University College London published a <a href="https://academic.oup.com/brain/article/doi/10.1093/brain/awaa240/5868408" target="_blank">study</a> in the journal Brain that describes how some patients have suffered temporary brain dysfunction, strokes, nerve damage, and other neurological problems concurrent with COVID-19.</p><p>Some patients suffered brain inflammation as a result of a rare disease called acute disseminated encephalomyelitis, which can cause numbness, seizures, and confusion. One patient in the study even hallucinated monkeys and lions in her home.</p>
