Consumption, contact and copulation: how pathogens have shaped human psychological adaptations

Consumption, contact and copulation: how pathogens have shaped human psychological adaptations. Debra Lieberman, Joseph Billingsley, Carlton Patrick. Philosophical Transactions of the Royal Society B: Biological Sciences, July 19 2018, Volume 373, issue 1751. DOI: 10.1098/rstb.2017.0203

Abstract: Disgust is an emotion intimately linked to pathogen avoidance. Building on prior work, we suggest disgust is an output of programmes that evolved to address three separate adaptive problems: what to eat, what to touch and with whom to have sex. We briefly discuss the architecture of these programmes, specifying their perceptual inputs and the contextual factors that enable them to generate adaptive and flexible behaviour. We propose that our sense of disgust is the result of these programmes and occurs when information-processing circuitries assess low expected values of consumption, low expected values of contact or low expected sexual values. This conception of disgust differs from prior models in that it dissects pathogen-related selection pressures into adaptive problems related to consumption and contact rather than assuming just one pathogen disgust system, and it excludes moral disgust from the domain of disgust proper. Instead, we illustrate how low expected values of consumption and contact as well as low expected sexual values can be used by our moral psychology to provide multiple causal links between disgust and morality.
