I'll always regret not taking those Psych general interest courses when I was focused on maths and sciences. It would have been helpful in spotting and dealing with the sociopaths hiding in plain sight.
Having said that, it's important to remember that every society is composed of individuals who reflect the full range of human behaviour, so try not to generalize or label.
It only feeds into the polarizing Partisanship and makes it easy to push your buttons.
Hope for the best and plan for the worst.
