>>325529your appearance is the first thing people judge you for and changes how people treat you. it directly affects how competent or intelligent you are believed to be, hence people internalise their looks as an extension of, or decider of, their self-worth. this is the halo effect, and it's not easy to overcome how entrenched it is within every life experience and interaction. if someone's pretty as a child people offer them increased opportunities to socialise and they're given better attention from teachers as well as parents, which goes on to influence a person's future. it's the thing that people care about the most - so people act like it, and take any hint that they're considered ugly as a deep violation of their dignity.
literally everything depends on how things "look" to people, because deciding based on visual cues is the path of least resistance, which our brain loves. individuals are less inclined to think of you as someone worthy of self-pride or attention if you're ugly, because your features disgust them. everyone is implicated in this. if someone finds your appearance repulsive then they subconsciously & consciously tend to opt you out of a more humane treatment/experience. they overlook you in favour of beauty. or worse, they treat you like a retard that needs to be pitied
this abuse based on looks can also impact growth. bullying can stunt development, and distract a person from learning or becoming competent due to poor mental health. it's all connected. though obviously the best approach is to do oneself the favour of caring about yourself and not wallowing time away in self pity forever
