A new theory of cognitive biases, called error management theory (EMT), proposes that psychological mechanisms are designed to be predictably biased when the costs of false-positive and false-negative errors were asymmetrical over evolutionary history. This theory explains known phenomena such as men's overperception of women's sexual intent, and it predicts new biases in social inference such as women's underestimation of men's commitment. In Study 1 (N = 217), the authors documented the…

Testing Error Management Theory: Exploring the Commitment Skepticism Bias and the Sexual Overperception Bias
Research on error management theory indicates that men tend to overestimate women's sexual interest and women underestimate men's interest in committed relationships (Haselton & Buss, 2000). We test
Error management and the evolution of cognitive bias.
Error management theory (EMT) proposes that when the costs of different types of errors are asymmetrical in their fitness consequences, natural selection will create biased cognitive mechanisms that
Could there be a male commitment skepticism bias and a female sexual overperception bias? Novel hypotheses based on Error Management Theory
Error management theory is an important and fruitful scientific theory. However, it might be useful to revisit the way we conceptualize the commitment skepticism bias and the sexual overperception

This article elaborate error management theory (EMT), predicting that if judgments are made under uncertainty, and the costs of false positive and false negative errors have been asymmetric over evolutionary history, selection should have favored a bias toward making the least costly error.

Error management theory (EMT) posits that when there are asymmetrical costs of falsepositive and false-negative errors over evolutionary history, selection will favor psychological mechanisms biased

This study was carried out as a direct replication of Haselton's (2003) original study of naturally occurring events of sexual misperception, showing that women reported being subject to opposite-sex sexual overperception far more often relative to underperception and that this difference was small for men.
Cognitive Biases and Emotional Wisdom in the Evolution of Conflict Between the Sexes
Two recent theories within evolutionary psychology have produced novel insights into conflict between the sexes. According to error management theory (EMT), asymmetries over evolutionary time in the

The article responds to Gigerenzer's critique and shows that it misrepresents the authors' theoretical position and ignores critical evidence.
Persistence of Men's Misperceptions of Friendly Cues Across A Variety of Interpersonal Encounters
This study examined whether gender differences in sexually based perceptions of social interactions persist when traditional male-female power roles are reversed, when the interaction becomes
Ten years of research on the false-consensus effect: an empirical and theoretical review
Ten years of research on the false-consensus effect (Ross, Greene, & House, 1977) and related biases in social perception (e.g., assumed similarity and overestimation of consensus) are examined in

Although errors can be highly informative about the process of judgment in general, they are not necessarily relevant to the content or accuracy of particular judgments, because errors in a laboratory may not be mistakes with respect to a broader, more realistic frame of reference and the processes that produce such errors might lead to correct decisions and adaptive outcomes in real life.

It is concluded that fear may be linked to biases that serve to confirm fear and the relevance of the present findings to preparedness theory is discussed.
Misperceptions of Friendly Behavior as Sexual Interest: A Survey of Naturally Occurring Incidents
The studies described in this article examine retrospective reports of naturally occurring misperceptions of friendliness as sexual interest. Previous research has demonstrated that men perceive
