Psychology isn't necessarily about therapy. It is the broad study of how minds work. I have studied a lot of it and the knowledge has come in very handy when it comes to getting people to do what I want them to.
Didn't bother with a degree in it though....you can learn all you need from reading and experimenting.
NB: Massively off original topic.
Assuming the subject hasn't changed since I studied over 40 years ago (I got two degrees in it and worked in area for a couple of years after that), I think its one of the subjects that are most misunderstand by laymen. And the one that most people fondly believe they are experts in.
For a start the thing most people forget is that psychology primarily studies normal behaviour, and all animal behaviour is studied not just human. There's a massive body of knowledge that's got nothing to do with mind. (Indeed many psychologists in my time thought considering "mind"was pointless, that you can predict behaviour without studying internal thought. That may seem bizarre…. but remember a lot of it can be about finding out what quite simple organisms do.)
After several years targeted study… reading widely, attending lectures and tutorials, and designing and carrying out controlled experiments in area…. I fondly believed I knew something about the subject. And a lot of it was about what happened to rats, not people.
But I was probably wrong… certainly every time I told people at a party what I studied, they corrected my beliefs on the subject because "No, I've read a book on subject and know you're wrong". Or even better (from a physicist) "Everybody can just work out psychology by studying their own thoughts".
