Invisible Mind
Why do people engage in pro and anti-social behaviour? Invisible Mind takes an interdisciplinary approach to address this question, among others, by focussing on the spontaneous psychological ability social cognition, and its inherent flexibility. People get inside the minds—infer the mental states—of others, including non-human agents and animals. Such social cognition is necessary for recognising another as a full human being, deserving of being included in the boundaries of moral protection, encouraging obedience to moral and social rules during social interactions. People can also withhold social cognition from other people, resulting a dehumanized perception, or extend it to non-human agents, resulting anthropomorphism. Harris argues that this flexibility is functional; social cognition evolved when people lived in much smaller groups, suggesting flexibility provided a fitness advantage specific to such a social environment, but may be occasionally maladaptive in modern societies. He reviews social, cognitive, evolutionary, and developmental psychology that supports this claim, before considering the implications of flexible social cognition for economics, legal theories, practice, and policy, international disputes, and athletic competition. He then explores what might be the consequences of flexible social cognition in modern societies where technology facilitates social communication and interaction.
