the person who wants to fool others begins by fooling themselves
Maybe it’s true, but I’d like to see evidence. Introspection is evidence. But you only claim to conclude from introspection that lying has costs, both internal psychic costs and leakage. That’s very far from claiming that people avoid those costs by fooling themselves. Which is independent of the claim that it’s the best way to do it, which is an evolution-ish claim from the link.
Also, I have no idea what “lie” means in this context. I’m pretty sure from other exchanges on this site that it does not lead to much successful communication. Maybe the general population, or even psychologists, can use the word uniformly clearly. But do they? I did once read a fairly specific EEA just-so story about this where it seemed to be purely about projecting confidence / arete and pretty far from the kind of declarative statement that I associate with lying. “I am the greatest” seems precise enough to be false, but I suspect that appearance is due to my speaking “nerd” rather than English. I don’t think most politicians have specific enough beliefs that they have to change them to say that. (But boxers, yes.)
