Flat earth beliefs

It is surprising there are not more anti-science beliefs.
1. Science isn’t static, there’s not much canon.
2. Science is mostly not a putting-a-man-on-the-moon problem.
3. Science communication persuasion is difficult, especially relative to cultures, norms, and habits.
4. Science belief doesn’t follow formal logic, it is contextual. There are plenty of people who don’t trust a medical engineering but trust engineered medicine, or vice versa.

One way to think about all the non-science beliefs is as three states of the world: -1, 0, and 1. Put another way: anti-science, ignorant, pro-science.

Sometimes science denial is an information problem. If people only knew…. But that’s not quite it. Yes, sometimes scientific knowledge is zero, ‘they just don’t know the facts’.

“The other thing I think is wrong about how the media portrays it (science denial) is as misinformation. Science denial is about disinformation. Someone has intentionally created the theory that rebreathing into a mask will give you CO2 poisoning. Someone has made that up and filtered it out through the internet where it hits someone’s cognitive bias and they start to believe it.” – Lee McIntyre, Behavioral Grooves, November 2021

Most of life is not a ‘they just know the facts’ situation. C’mon, how many things do you dear reader not hold an opinion on. More often, it’s not non-consumption, but belief in something else. Weight Watchers and financial education are also examples of this state. Plus, our views on science and medicine, finances, and diet-health-lifestyle all have a strong identity component. If someone said, “Look, I hear what you are saying but I don’t trust the experts and this online community are my people,” you would have no idea if they were a Boglehead, a CrossFit participant, or anit-vax father of two.

The case at hand is like an errant Sudoku puzzle, there’s something else in that spot and it’s attached to a person’s identity.

Around here we try to skip the ‘they just don’t know the facts’ stage and go right to designing change. Personal finance is about shifting what we buy, often time rather than stuff. Heath is about shifting what we eat and what we do, replacing one thing with a healthier option. Anti-science persuasion then must replace the anti-science beliefs with something else. The trick here, says McIntyre is to plant a seed. Rather than ‘the facts’, be empathetic and offer suggestions. Reframe your aim from conversion to combustion, be the spark but let them do the work.


It is wild how many things we do become part of our identity.

Update February 15, 2022. Even ‘hard’ sciences are hard. Only forty percent of cancer biology studies replicated and eighty percent of pharmaceutical studies in academic labs cannot be replicated in industrial ones. Also, plastic recycling has (always?) been a sham: NPR Planet Money.
