I love thinking about human psychology. In particular, I love thinking about things humans do that are non-obvious, but pervasively drive their behaviour.
I can think of two general principles that drive a great deal of human behaviour, yet are non-obvious.
I have to start this post with some self-reflection. It's easy to believe that only stupid people get swept up in cults. I heard a few years ago, however, that in fact intelligent people are in fact more likely to join a cult (article, reference).
As a practising Christian, I've therefore spent a lot of time considering whether I'm just another naive cult member.
