So here it is: I look at the left half and think "Boring pain in the ass", I look at the right and think "She's so nice".
I reverse discriminate. I didn't know. I really didn't know until I saw that this is literally the same person and how she looks affects my perception of her.
Lots of college girls do this. Lots of my students like doing this. I have half a dozen girls that look like the left in every single class I have. Sure, some of them are so great they rise to the top, but how many were just average until something I did subconsciously, made them disengage?
It gets worse. How many needed my help and didn't get it?
I might cry. Or throw up.
