Why fatties think they have wonderful personalities We all know they don't, so where does this myth come from of "beautiful on the inside"?  Fatties are pretty much universally every bit as ugly on the inside as they are outside. I have two complementary theories: Most All fatties are just awful people and rotten to everyone.  Therefore, if a fatty acts even remotely human, it is celebrated as being a great person.  Everything is relative and so when you're expecting the fatty to just be an obnoxious asshat and it is only as much of an asshole as a normal person, you may be tempted to think it's got a great personality.  In reality, it's just like if you were expecting to get hit with a sledgehammer and just got hit with a stick instead.   The Just world theory.  The application here is that if someone is a disgusting, unattractive blob, they must be able to make up for it somewhere else.  This, of course, goes hand in hand with how most of society tries not to blame fatties for their fatness and assumes they are fat because of bad luck.
