A scar experiment done at Dartmouth University painted disfiguring scars on subjects to determine how people would react to them. But in a twist, the scars were actually removed before the interactions without the subjects knowing.
The subjects, thinking they were disfigured but actually not, "overwhelmingly reported back that people stared at their scars, and were mean and rude to them."
As I say I am still trying to figure out what this means. Maybe being uncomfortable with your looks makes you feel discriminated agaisnt even when you are not. And conversely being comfortable in you looks makes you more likely to feel you are treated fairly.
And I suppose it might extend to more than looks. Intelligence, wealth, or basically nay thing you feel uncomfortable about.
But take it with a grain of salt as it was a very small study.
