How to have a constructive conversation with vaccine skeptics
Jonathan Berman wants us to have better dialogues.
- In his book, "Anti-vaxxers," science educator Jonathan Berman aims to foster better conversations about vaccines.
- While the anti-vax movement in America has grown, more Americans now say they'll get a COVID-19 vaccine.
- In this Big Think interview, Berman explains why he's offering an ear to the anti-vax movement.
As two COVID-19 vaccines roll out in America, Pew Research reported a rare glimmer of hope in the ongoing saga of vaccine disinformation: the number of citizens willing to get a vaccine increased to 60 percent. The trend is moving in the right direction, course-correcting anti-vaccination rhetoric that led to the first increase in measles cases (and the highest number of measles deaths) in the modern era.
While we have fabricated research by disbarred doctor Andrew Wakefield to thank for this trend, anti-vaccination efforts are tethered to the first vaccinations. As with seemingly every topic, vaccines are a wedge issue, with a fervent cohort of anti-vaxxers going so far as to be "single-issue voters."
Jonathan Berman, an assistant professor in the Department of Basic Sciences at NYITCOM-Arkansas, grew tired of seeing all of the "dunking on anti-vaxxers." As with many science advocates, he grew skeptical of the anti-vaxx movement while studying for his degree in the aughts. Though he agreed with Richard Dawkins and Christopher Hitchens, he recognized them as bullies. Berman wanted to grapple with the underlying reasons for opposing vaccination rather than just write them off.
Those reasons, which comprise a chapter of his recent book, "Anti-vaxxers: How to Challenge a Misinformed Movement" (MIT Press), include issues of social class, race, individual liberties, individual and collective rights, distrust of authority, and changing ideas about health and medicine. Instead of exhibiting knee-jerk reactions, he wants to offer compassion and empathy while expressing critical thinking when analyzing the science of vaccines. As Berman recently explained of anti-vaxxers,
"They're making a risk evaluation just like we're making a risk evaluation. They're doing it in a less reasonable and healthy way and arriving at the wrong decision. That doesn't mean that we have to call them stupid or act like they're foolish. It means we can have a conversation with them. Hopefully, that's a more productive way to go about it."
Conspirituality 31 interview: Jonathan Berman
As he wrote the book before the pandemic hit, Berman is a bit dismayed (though not surprised) by the growth of the anti-vaccine movement. He noticed a convergence point this year: anti-mask and anti-lockdown proponents (as well as QAnon devotees) learned a set of tactics from the longstanding anti-vax movement, while anti-vaxxers took the energy of "personal liberty" and "bodily sovereignty" being expressed by those groups.
There have been a number of anti-vax leaders whose star has risen this year: Mikki Willis has surged since the release of his Plandemic film; Del Bigtree, whose show "The Highwire" is in large part funded by hedge fund managers, is growing more influential; and gynecologist Christiane Northrup, who has used her social media platforms to promote QAnon-related and anti-vax sentiments, is also seeing a rise in followers. As Berman writes, celebrities are not the best sources of information, and their intentions might not be as benevolent as they seem.
"There's a degree of grift in what they're doing. They're collecting donations from their audience of anti-vaccine people they've built up."
Science sometimes suffers from lack of celebrity. Paul A. Offit will never be Neil deGrasse Tyson or Bill Nye. While a select few science educators break through, vaccination advocates are unlikely to achieve that level of star power. Berman, one of the founders of the "March for Science" movement—a rare mainstream moment of science advocacy in the Trump era—knows the difficulty of spreading the gospel of sound scientific methods.
Navigating the tricky terrain of vaccines is difficult. Thankfully, Berman's excellent book offers hope. Twenty-two concise chapters pack a lot of punch: the history of both vaccines and the anti-vax movement; dangerous ploys by grifters; the science of vaccines; and a chapter on vaccine ingredients, like adjuvants.
While Berman is pro-vaccine, he believes Pfizer and Moderna deserve scrutiny. Commentary from outside organizations and researchers should be offered. That said, while pharmaceutical companies certainly have a track record of corporate greed, vaccines only account for 2 percent of profits—hardly cash cows like painkillers and antidepressants.
Berman laughs off the occasional criticism that he's a paid shill. "I'm still on the negative on the book—just because of caffeine purchases while I was writing it."
Disinformation abounds in the modern era. Posts about the dangers of thimerasol and aluminum persist even though neither are in the Pfizer vaccine. Berman advocates for pushing back against misinformation with better data.
"The coronavirus vaccine—these are very simple formulations. There's salt, RNA, and a lipid to help the RNA cross cell membranes. If someone says there's aluminum in that, you can say, 'not in this one.' And if someone says there's mercury in that, you can say, 'not in this one.'"
He knows the challenges that lie ahead. Still, as Pew shows, more Americans understand the role that vaccines play in reaching a post-pandemic world. Berman concludes our talk on what you might say is a hopeful note.
"We're not going to get everyone on board. We just need to get enough people on board."

A new study finds that dogs fed fresh human-grade food don't need to eat—or do their business—as much.
- Most dogs eat a diet that's primarily kibble.
- When fed a fresh-food diet, however, they don't need to consume as much.
- Dogs on fresh-food diets have healthier gut biomes.
Four diets were tested<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTU5ODI1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NjY0NjIxMn0._w0k-qFOC86AqmtPHJBK_i-9F5oVyVYsYtUrdvfUxWQ/img.jpg?width=980" id="1b1e4" class="rm-shortcode" data-rm-shortcode-id="87937436a81c700a8ab3b1d763354843" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="960" />

Swanson</a> of U of I's Department of Animal Sciences and the Division of Nutritional Sciences, was a bit surprised at how much better dogs did on people food than even refrigerated dog chow. "Based on past research we've conducted I'm not surprised with the results when feeding human-grade compared to an extruded dry diet," he <a href="https://aces.illinois.edu/news/feed-fido-fresh-human-grade-dog-food-scoop-less-poop" target="_blank">says</a>, adding, "However, I did not expect to see how well the human-grade fresh food performed, even compared to a fresh commercial processed brand."</p>

This resulted in their producing 1.5 to 2.9 times the amount of poop produced by dogs on the fresh diets.</p><p>Says Swanson, "This is consistent with a 2019 National Institute of Health study in humans that found people eating a fresh whole food diet consumed on average 500 less calories per day, and reported being more satisfied, than people eating a more processed diet."</p><p>Maybe even more interesting was the effect of fresh food on the gut biome. Though there remains much we don't yet know about microbiota, it was nonetheless the case that the microbial communities found in fresh-food poo was different.</p><p>"Because a healthy gut means a healthy mutt," says Swanson, "fecal microbial and metabolite profiles are important readouts of diet assessment. As we have shown in <a href="https://academic.oup.com/jas/article/92/9/3781/4702209#110855647" target="_blank">previous studies</a>, the fecal microbial communities of healthy dogs fed fresh diets were different than those fed kibble. These unique microbial profiles were likely due to differences in diet processing, ingredient source, and the concentration and type of dietary fibers, proteins, and fats that are known to influence what is digested by the dog and what reaches the colon for fermentation."</p>
How did kibble take over canine diets?<p>Historically, dogs ate scraps left over by humans. It has only been <a href="https://www.thefarmersdog.com/digest/the-history-of-commercial-pet-food-a-great-american-marketing-story/" target="_blank">since 1870</a>, with the arrival of the luxe Spratt's Meat Fibrine Dog Cakes—made from "the dried unsalted gelatinous parts of Prairie Beef", mmm—that commercial dog food began to take hold. Dog bone-shaped biscuits first appeared in 1907. Ken-L Ration dates from 1922. Kibble was first extruded in 1956. Pet food had become a great way to turn <a href="https://www.dogfoodadvisor.com/choosing-dog-food/animal-by-products/" target="_blank">human-food waste</a> into profit.</p><p>Commercial dog food became the norm for most household canines only after a massive marketing campaign led by a group of dog-food industry lobbyists called the Pet Food Institute in 1964. Over time, for most households, dog food was what dogs ate — what else? Human food? These days more than half of U.S. dogs are <a href="https://www.nytimes.com/2014/08/03/magazine/who-made-that-dog-biscuit.html" target="_blank">overweight or obese</a>, and certainly their diet is a factor.<span></span></p><p>We're not so special among animals after all. If something's healthy for us to eat—we're <em>not</em> looking at you, chocolate—maybe we should remember to share with our canine compatriots. Not from the table, though.</p>
New study suggests the placebo effect can be as powerful as microdosing LSD.
- New research from Imperial College London investigated the psychological effects of microdosing LSD in 191 volunteers.
- While microdosers experienced beneficial mental health effects, the placebo group performed statistically similar to those who took LSD.
- Researchers believe the expectation of a trip could produce some of the same sensations as actually ingesting psychedelics.

Volunteers were already microdosing LSD, so there was no true control. Each volunteer was given instructions on creating their own low-dose gel capsules, some containing LSD, others not. Then they mixed the capsules in envelopes so they didn't know if they were taking the real thing or not.</p><p>The trial design was ingenious: each capsule featured a QR code that was scanned after the addition of ingredients but before they were placed in the envelope so that researchers knew what they were ingesting.</p><p>The problem: volunteers sourced their own LSD. Lack of quality control could have had a profound effect on the results. </p><p>The results: LSD microdosers reported feeling more mindful, satisfied with life, and better overall; they also noticed a reduction in feelings of paranoia. </p><p>The catch: the control group felt the same thing, with no statistical difference between the groups. </p><p>Lead author Balázs Szigeti comments on the findings: "This suggests that the improvements may not be due to the pharmacological action of the drug but can instead be explained by the placebo effect." </p>
Credit: Alexander / Adobe Stock<p>Psychedelics are notoriously difficult to control for given the intensity of the experience. Yet there is precedent for the above findings. A <a href="https://link.springer.com/article/10.1007/s00213-020-05464-5" target="_blank">2019 study</a> found that 61 percent of volunteers that took a placebo instead of psilocybin felt some psychedelic effects, with a few volunteers experiencing full-on trips.</p><p style="margin-left: 20px;">"Several stated that they saw the paintings on the walls 'move' or 'reshape' themselves, others felt 'heavy. . . as if gravity [had] a stronger hold', and one had a 'come down' before another 'wave' hit her."</p><p>The Imperial team believes the expectation of a trip might have been enough to produce similar results. Senior author David Erritzoe is excited for future studies on the topic, believing they tapped into a new wave of citizen science that could push forward our knowledge of psychedelic substances.</p><p style="margin-left: 20px;">"Accounting for the placebo effect is important when assessing trends such as the use of cannabidiol oils, fad diets or supplements where social pressure or users' expectations can lead to a strong placebo response. Self-blinding citizen science initiatives could be used as an inexpensive, initial screening tool before launching expensive clinical studies."</p><p>As investments into the psychedelics market explode, with one company <a href="https://www.bloomberg.com/news/articles/2021-03-03/thiel-backed-magic-mushroom-firm-atai-hits-2-billion-valuation" target="_blank">reaching a $2 billion valuation</a>, a recurring irony appears in the long arc of psychedelics and research: the power of our minds might be enough to feel greater life satisfaction and a deeper sense of mindfulness. If that's possible with a placebo, we have to question why the rush to create more pharmacology is necessary. </p><p>This is, mind you, a separate conversation over the role of psychedelics and rituals for group bonding. The function of group cohesion around consciousness-altering substances will continue to play an important role in many communities. </p><p>Of course, we should continue to explore the efficacy of psychedelics on anxiety, depression, suicidal ideation, PTSD, and addiction. <a href="https://bigthink.com/surprising-science/antidepressant-effects" target="_self">Pharmacological dependence</a> is a stain on the psychiatry industry.

What makes some people more likely to shiver than others?
Some people just aren't bothered by the cold, no matter how low the temperature dips. And the reason for this may be in a person's genes.
