David Marchese in the New York Times:
Your new book is driven by the idea that it would be good if more people thought more rationally. But people don’t think they’re irrational. So what mechanisms would induce more people to test their own thinking and beliefs for rationality?
Ideally there’d be a change in our norms of conversation. Relying on an anecdote, arguing ad hominem — these should be mortifying. Of course no one can engineer social norms explicitly. But we know that norms can change, and if there are seeds that try to encourage the process, then there is some chance that it could go viral. On the other hand, a conclusion that I came to in the book is that the most powerful means of getting people to be more rational is not to concentrate on the people. Because people are pretty rational when it comes to their own lives. They get the kids clothed and fed and off to school on time, and they keep their jobs and pay their bills. But people hold beliefs not because they are provably true or false but because they’re uplifting, they’re empowering, they’re good stories. The key, though, is what kind of species are we? How rational is Homo sapiens? The answer can’t be that we’re just irrational in our bones, otherwise we could never have established the benchmarks of rationality against which we could say some people some of the time are irrational.
