adlerian psychology is beneficial in helping individuals understand the root of their behavior because behaviors are reflections of someone's goal and goals are simply someone thriving for superiority. Inferiority and superiority are completely objective because let's say one is penurious but if he/she doesn't believe that the amount of wealth defines him/her, he/she might not feel inferior. on the other hand one might feel inferior on something that society doesn't even give a damn about. that person therefore feels inferior when people don't actually think of him/her that way. there's a lot to this theory tho but i mentioned this part of it specifically for a reason. although adler wrote about this in hopes to understand people's behavior based on the subconscious, conscious, goals, inferiority and superiority complexes, n all those, if you're asking my thoughts, i learned that inferior feelings that people have might be an illusion... apart from that i have no thoughts on it, im no psychologist lol
