You can probably guess what drew me to this book. As a pastor and public theologian, it has become imperative that I know how to communicate with anti-vax, anti-mask, Qanon conspiracy theorists. And it’s not just because these are people I, as an evangelical Christian leader, need to counter. It’s because these are my people. Somehow, in some way—and you can trace it back to Scopes monkey trial—evangelical Christians became wary of science. (And in the secular realm, McIntyre traces it to cigarette and oil companies trying to effect public opinion on smoking and climate science, respectively.) In recent years, that occasionally healthy skepticism has blown into full-on denial and conspiracy in everything from climate change to COVID. How to Talk to A Science-Denier is a memoir/guidebook that tries to understand why people genuinely and earnestly believe in conspiracy theories and how we can best bring them back to reason.
Author Lee McIntyre is a research fellow at the Center for Philosophy and History of Science at Boston University and an Instructor in Ethics at Harvard Extension School. He has a Ph.D. in philosophy from University of Michigan and his professional interest has always been with the nature of how we obtain and validate scientific knowledge. The very first chapter sets the tone for the book, detailing McIntyre’s experience at a Flat Earth Convention. The conversations he relates range from the normal to the bizarre, highlighting how science-deniers aren’t all mentally ill, stupid, or brainwashed. Many of them live otherwise normal lives. This human element is one that McIntyre latches on. Talking to science-deniers as equals and as people, conversing with a genuine desire to understand their perspective and respecting their position becomes the best way to have any real effect on their beliefs and actions.
How to Talk to a Science-Denier is a thorough, philosophical, and thoughtful. Even though his Ph.D. is in philosophy, McIntyre writes like a sociologist—think of a more-academic and not quite as charismatic version of Malcolm Gladwell. The book is published by a MIT Press and is at about the level you’d expect from an academic publication. It sort of wavers between your typical lay-level, accessible style of writing and true academic treatise. It’s denser than Malcolm Gladwell but its hardly post-graduate philosophy. It’s a bit of a slow read as a result and while I enjoyed it, I think that if McIntyre had reworked this to a more popular-level style, it may have gained more traction. But academic publishing is McIntyre’s wheelhouse, so go with what you know, I guess.
Early on, he makes the case that both content rebuttal and technique rebuttal can be effective in countering science-deniers, if it is done in compassionate manner as a part of genuine conversation. Yelling out talking point and smug gotchas does nothing. Sincerely asking “oh, how do you account for…” actually forces the individual to consider a response. (Theologian sidenote: Jesus was super good at questions like this. ‘Whose face is on this coin?’ ‘Which of these was a neighbor?’)
One thing I wish How to Talk to a Science-Denier had covered more thoroughly is how to talk to a science-denier who themselves are science-experts. Science is a very broad field and experts in science are, by necessity, experts in only narrow, narrow slice of science and may be as ignorant as anyone else in other areas. Yet, having the title of “Doctor” often gives individuals carte blanche for opinions all over the place. COVID has seen a number of doctors promote disproven cures or doctors and nurses be strongly anti-vax. They may the minority, but those are the voices science-deniers lift up as saying “Look, here is a scientist and they agree.”
Overall, How to Talk to a Science-Denier isn’t a cure-all. But it might help you begin some conversations. It’s a not a magic incantation to make the other side see reason, but it just might help you see the other side as human—and understand their motives and reasons. And it might help them understand yours as well.
