Before any of this, one thing needs saying: I am not presenting myself as somebody immune to it.
I have owned a lucky shirt. I have knocked on wood.
The difference between me and the people in this book is not that I am incapable of irrational thinking. It is that I have never let irrational thinking kill anyone. That bar, depressingly, turns out to be higher than you would expect.
Why does that distinction matter so much?
Because it is the whole line, and almost nobody draws it in the right place.
People imagine a boundary between rational persons and irrational ones, with themselves comfortably on the correct side. That boundary does not exist. Almost everybody carries beliefs that would not survive examination, and most of them are harmless because nothing has been built on top of them.
The lucky shirt decides nothing. It costs nothing. If I wear it and things go badly, I do not adjust anything except possibly my choice of shirt.
The beliefs in this book are structurally identical and load-bearing. Somebody has decided what treatment to take, who to trust, which family members to stop speaking to. The reasoning is not worse than mine about the shirt. The consequences are enormously different.
Why do intelligent people believe absurd things?
Because the belief is doing a job that has nothing to do with evidence.
It explains something painful that otherwise has no explanation. It supplies membership of a group that takes you seriously. It offers control over a situation where you have none, which is the most powerful of the three and the least discussed.
Intelligence does not protect against any of that. What intelligence does is improve the quality of the justification. A clever person constructs a better defense of a conclusion they arrived at for reasons that were never argumentative in the first place.
This is why credentials in the audience change so little. The reasoning is downstream of the need.
Why is evidence demanded so selectively?
One pattern recurs throughout the book.
The same person will demand peer-reviewed evidence for the safety of a medical treatment, and accept a blurry video of keys apparently sticking to somebody’s arm as definitive proof of magnetism. They will dismiss decades of development as untrustworthy while completely trusting anonymous posts and videos by people whose scientific credentials consist of having done their own research.
From outside, that looks like hypocrisy. It is not, and treating it as hypocrisy guarantees you will get nowhere. The standard of evidence is being set by which conclusion is wanted, and the person applying it experiences no contradiction at all, because they are not running an evidential process. They are running a social and emotional one that borrows evidential language.
The book on this: Ridiculous Things People Actually Believe is 18 chapters through flat earth, medical delusion, secret societies and the rest, looking at what the belief is doing for the believer.
Does debunking help?
Usually it makes things worse, and this is the finding that changed how I write about the subject.
Direct contradiction from outside the group confirms something the belief already contains: that outsiders are hostile and cannot be trusted. Every fact you present is evidence for the thing you are trying to disprove.
That does not mean saying nothing. It means recognizing that the argument is not where the work happens. What moves people, in the accounts I have read and the cases I have watched, is almost never a decisive fact. It is a relationship that stayed intact long enough for them to have somewhere to go when the belief stopped serving them.
What about beliefs that hurt people?
Some of these are genuinely dangerous, and the medical ones are the clearest case.
A flat earth belief costs the believer very little. Somebody’s cousin is out fifty dollars on a laser. A belief that a proven treatment is poison and an unproven one is a cure decides whether a person is alive in two years, and it frequently decides it for their children as well.
I do not think mockery has any role there, and not on grounds of politeness. Mockery hardens the position and removes you as somebody they might listen to later. It is the least effective available response and it is enormously satisfying, which is why it is the most common.
What is worth doing?
Ask what the belief is providing. Explanation, belonging, or control. The answer tells you what would have to be replaced.
Notice your own version. Everybody has one. Mine is a shirt.
Check what you have built on top of it. That is the real question, not whether the belief is true.
Do not debunk from outside the relationship. It confirms the thing you are arguing against.
Stay in contact. The people who come back are the ones who had somebody to come back to.
The lucky shirt is still somewhere in a drawer. I do not believe it works and I have not thrown it out, and holding both of those at once is roughly the human condition.
