Why Science Must Embrace Imagination, Intuition, and Evidence
All science begins with a leap of intuition, says Richard Dawkins, but we can only ever find objective truths by knowing when to let evidence take over from emotion.
Richard Dawkins is an evolutionary biologist and the former Charles Simonyi Professor of the Public Understanding of Science at Oxford University. He is the author of several of modern science's essential texts, including The Selfish Gene (1976) and The God Delusion (2006). Born in Nairobi, Kenya, Dawkins eventually graduated with a degree in zoology from Balliol College, Oxford, and then earned a masters degree and the doctorate from Oxford University. He has recently left his teaching duties to write and manage his foundation, The Richard Dawkins Foundation for Reason and Science, full-time.
Richard Dawkins: The first chapter of 'Science in the Soul' is called 'The Values of Science and the Science of Values'. And it does, of course, give prominence to objective truth. There is a kind of whispering campaign—more than a whispering campaign, sometimes a yelling campaign—against the value of objective truth. Science, I think, is committed to objective truth; we’re committed to the view that truth is independent of the cultural background of the scientist, for example. So as I said in the book, an experiment done in a lab in New York can be replicated in a lab in New Delhi, and if it’s all done correctly in the same way they’ll get the same result. Science’s belief in objective truth works. Engineering technology based upon the science of objective through achieves results: it manages to build planes that get off the ground, it manages to send people to the moon and explore Mars with robots, and land robotic vehicles on comets. Science works. Science produces antibiotics, it produces vaccines that work. So anybody who chooses to say, “Oh, there’s no such thing as objective truth, it’s all subjective, it’s all socially constructed,” tell that to a doctor, tell that to a space scientist.
Manifestly, science works and the view that “there is no such thing as objective truth” doesn’t. Science proceeds, I believe, in the sort of Popperian view that science proceeds by intuitive leaps of the imagination, building an idea of what might be true and then testing it by experiment, by observation, in the second phase. It’s a kind of Darwinian selection of mutation, which is provided by the imagination.
So intuition is very important, but it is important that scientists should not be so wedded to their intuition that they omit the very important testing phase, and if their hypothesis is disproved they should regard that as a reason to reject the hypothesis or modify it, not a reason to just carry on doggedly sticking to the hypothesis because they are intuitively committed to it.
The phrase 'critical thinking' is quite a cliché but it is immensely important. And so I think that I really could sum it up by saying what we need is critical thinking; we need to respect evidence, we need to respect the fact that the only reason to believe anything about the real world is evidence. The evidence must be assessed critically, preferably statistically and logically. You cannot derive truths about the real world by intuition alone, by feelings alone, by what feels good.
People who say things like, “All opinions are equally valid,” or, “Well, it’s true for me, it may not be true for you.” Never tolerate that kind of thing. The only reason to believe anything is true is that there’s evidence, and everybody should either look at the evidence for themselves or they should trust that the person they’re talking to has looked at the evidence in a scientific, logical, rational, critical way.
Just for example, I’m not qualified to assess the evidence of modern physics experiments, I’m just not qualified. So I have to trust—this is not trusting authority so much as trusting the scientific method, which I know has been used by physicists whom I can’t directly assess, it has been used by physicists who are using the same techniques as I know work in my own field of biology.
You can be committed to science, but as soon as you're committed to a hypothesis, you've walked off the trail of objective truth, says Richard Dawkins. For him, that is the mission of science and the purpose of the scientific method: these truths exist—they are the foundations of innovations like vaccinations, antibiotics, and space travel, because they are built on something solid: evidence. Einstein is known for highly valuing the role of imagination in science, and Dawkins agrees: imagination and intuition are the springboards scientific progress depends on—but when evidence refutes a hypothesis or a feeling, that's the end of the line. Dogged persistence doesn't get you any closer to the truth, says Dawkins, only critical thinking can do that. Richard Dawkins' latest book is Science In The Soul: Selected Writings of a Passionate Rationalist.

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

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.
