actually, (im a self taught student of psychology, so i could be wrong) A mindset that i've found in all the people i've ever met, (tbh, they're american, so I cant vouch for other countries or other individuals) They are so focused on categories. I call it the box syndrome
Example: Villains are automatically evil. Heroes are automatically good. Racist people are stupid.
instead of: Villains are traumatized. Heroes just fight the villain, they're neutral. Racist people were raised in that mindset, and should be gently educated in their wrongdoings.
Think about it. We have boxes in our minds where we put our feelings. Alone is sad. Angry is bad. Because of that, I see many adults, even the wisest among them, closed-minded, boxing everything.
It's kinda why I like kids better. They don't box things. They don't have to be right. They just be, letting their emotions and thoughts about people flow in a river, unboxed, untangled, and open-minded. I don't know though. Maybe I just take comfort in the grey areas of life.
