Why does the uncanny valley[1] exist? (If it truly does.) What in our evolutionary history gave us a reflexive rejection of things that seem human but aren't? 1. https://en.wikipedia.org/wiki/Uncanny_valley
Perhaps it's down to the fact that a lot of communication is contextual/ group bonding? You are expected to behave a certain way. If you laugh at something the group doesn't find funny, you are excluded from the group. Visa versa. If something does behave quite right, it doesn't belong in the group?
I'm autistic for what it's worth. I'm not sure if that gives me better of worse insight into group dynamics.
