Behaviourism
For a few years now I've been pointing out in various discussions that a lot of govt. policy has been based on behaviourism. A belief that we can be taught, controlled and "nudged" using these ideas. Much of education has been taken over by that sort of policy. Everything has been broken down into mechanical skills that are taught individually in sequence, tested individually before passing onto the next level. It has a pseudo-logical "stands to reason" attractiveness that ignores the messy, complicated way that we do actually learn.
Ditto how we behave. We don't really behave in that selective, logical, individual decision way and behaviourism can only have a limited influence on our decisions. Other things get in the way, like how we see other people behaving.
