> Many people are saying that they only look angry, and that they actually aren't angry. This may be 100% true, but the facial feedback hypothesis suggests I used to know someone like that; even when she smiled, her eyes seemed to have a pained crinkle around the edges. She insisted that she felt fine, that it was just a trick of her facial features - but she tended to get aggravated by other people so easily that it was hard to believe her. I suspect that she was simply accustomed to a baseline feeling of irritation and didn't really notice its presence. (Validating the facial-feedback hypothesis further, I knew someone else who got botox treatment for her forehead, so she could no longer scowl; this notably improved her mood.)
