> If you look at how people act in work, family and love life, signalling explains 90% of it. But it equally explains why I don't buy a car (because I want to signal that I'm not the sort of person who would) as much as explains why I do by a car (ditto). So of course it "explains" 90% of how people behave, but only after the fact. Which is suspicious.
