The thing about psychology is that it is the best study of humanity.
Unlike archeology or history or evolution,etc., the study of psychology is studying the one thing that makes us human and makes us alive.
If we were really dumb animals without consciousness then humanity would be equal to nothing - or in fact equal to dirt.
It is out thinking and our mental processes that makes us alive, and psychology studies that - psychology is the study of humanity in our purest form.
Yet most people seem to go through life with out-of-control emotions and unrecognized feelings like sheep doing their master's biddings.
Learn meaningless crud like all about sports, learn all about money and averice, learn science and medicine, but just mention the terminology like "mental illness" or "mental health" and the majority will run and hide from the idea of it.
I find the vast majority of humanity to be rather irritating and in the likeness of animal.
