Let’s not forget the converse: Fear that the other person will be creeped out.
I suspect that’s not a true answer. You could hypothetically feel pleased when you creep someone out. That’s a possible state for a human.
So it may not be “them feeling creeped out” that you avoid, but “you having an obligation to feel bad when you creep someone out”, and you avoid that state of feeling bad. Which is slightly different.
Do you have any evidence of this?
Or, since that is a bit tautological, do you have any evidence that the things we want to change (social interaction fears, for instance) are the unchangable “hardwired results of evolution”, and not the malleable program running on top (for want of a better description)?
