What is 'overperception bias' in Psychology?

Also known as the sexual overperception bias, this refers to the tendency among people to overestimate the level of sexual interest that others have in them. It is believed that men are more likely to overestimate the interest level of women. On the other hand, women are said to underestimate men’s interest level. This is attributed to the fact that the evolutionary cost of underestimation is relatively high for men when compared to women. The overperception bias is considered to be a corollary of the sexual underperception bias which refers to the tendency among people, mostly women, to underestimate the interest level of people of the opposite sex.
