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 cost-benefit consequences of specific social inferences have produced predictable cognitive biases. Women, for example, appear to underinfer commitment in response to signals of resource display. Men often overinfer a woman's sexual desire when she merely smiles at or casually touches them. These inferential biases, according to EW, represent functional adaptations rather than markers of irrationality in information processing. According to strategic interference theory, certain "negative emotions" function to motivate action to reduce conflict produced by impediments to preferred social strategies. Emotions such as jealousy and anger, rather than reducing rationality, may embody inherited ancestral wisdom functional in dealing with interference inflicted by other individuals. These evolution-based theories have produced novel empirical discoveries and challenge traditional theories anchored in the premise that cognitive biases and negative emotions necessarily lead to irrationality.
