according to research, attractive people are more successful in life

being more attractive leads to people being nicer to you
people being nicer to you makes you think the world is a nice place
thinking the world is a nice place makes you a happier person
being happier makes you able to concentrate on your life more easily and complete tasks quickly

being ugly makes people ignore you or act rude to you
this makes you think the world is a shitty place
as a result you're always irritated and can't concentrate on tasks or make as much progress in life

"more attractive people are more successful" is a self-fulfilling prophecy
by thinking they're more successful, people give them more options
by getting more options, they become more successful

with this in mind,

why is not everybody using the latest and greatest booth avatars as their vrchat model? why would you gimp yourself by being less beautiful than the best option available to you?

it is no secret to anybody that by using a prettier avatar, people are nicer to you, have more patience for you, are willing to forgive your mistakes more easily, and want to be around you more often

unlike rl, in vr you can actually pick how you look

why would you pick anything but the most beautiful avatars available?
so why not use it?
