One thing I am going to remember from Psychology 1001 is the concept of determinism. I think a large part of that has to do with the fact that I think it's really strange. Determinism is basically the idea that free will doesn't actually exist (p. 595). Determinism holds that our actions are pre-determined by our genetic make-up and life experiences. The work that psychologists do is essentially done off the assumption that determinism is correct. Psychology rests on the idea that someone's actions can be explained either by genetics or their environment. I can't really find anything wrong with that. What else could factor into why someone would do something?
Because before Psychology 1001 I felt pretty strongly that free will did exist, this process of changing my mind is something that I won't forget. Which I guess means that I won't forget about belief perseverance either. The fact that I changed my mind in light of new evidence means that I didn't succumb to belief perseverance. Hopefully, I won't in the future either now that I'm aware of it.
This is funny sign about determinism I found:

And this is some of what our book has to say about free will and determinism (p. 595):


My adviser and I actually debate on this quite frequently and I have some ideas that may pull you back to the idea of free will or at least a bit more of a combination.
