Do unattractive people really think they are attractive?

Seems like physically unattractive people are so vain. I noticed most attractive guys and girls are more insecure compared to unattractive people. I can totally understand a butterfaced girl being appealing but fat old guys think they are hot shit and keep chasing attractive 18-25 year old females around.
