The sexual overperception bias: Evidence of a systematic bias in men from a survey of naturally occurring events

According to error management theory (Haselton & Buss, 2000), natural selection will often produce adaptively biased systems of judgment, even when these systems produce more errors than alternative designs. In a study of naturally occurring events, evidence of one such bias in men-the sexual overperception bias-was documented. Women (n = 102) and men (n = 114) reported past experiences in which a member of the opposite sex erroneously inferred their sexual interest. Women reported significantly more false-positive errors committed by men than false-negative errors. Men reported roughly equal numbers of false-positive and false-negative errors committed by women, suggesting no bias in women's sexual inferences. Several within-sex predictors of misperceptions were identified; for example, individuals high in self-perceived mate value reported more false-positive inferences by others than did individuals lower in mate value.
