TLDR
It is suggested that in addition to motivating pathogen avoidance, disgust evolved to regulate decisions in the domains of mate choice and morality and is recast into a framework that can generate new lines of empirical and theoretical inquiry.Abstract:
Interest in and research on disgust has surged over the past few decades. The field, however, still lacks a coherent theoretical framework for understanding the evolved function or functions of disgust. Here we present such a framework, emphasizing 2 levels of analysis: that of evolved function and that of information processing. Although there is widespread agreement that disgust evolved to motivate the avoidance of contact with disease-causing organisms, there is no consensus about the functions disgust serves when evoked by acts unrelated to pathogen avoidance. Here we suggest that in addition to motivating pathogen avoidance, disgust evolved to regulate decisions in the domains of mate choice and morality. For each proposed evolved function, we posit distinct information processing systems that integrate function-relevant information and account for the trade-offs required of each disgust system. By refocusing the discussion of disgust on computational mechanisms, we recast prior theorizing on disgust into a framework that can generate new lines of empirical and theoretical inquiry.read more

The Righteous Mind: Why Good People Are Divided by Politics and Religion
TL;DR: Haidt as mentioned in this paper argues that the visceral reaction to competing ideologies is a subconscious, rather than leaned, reaction that evolved over human evolution to innate senses of suffering, fairness, cheating and disease, and that moral foundations facilitated intra-group cooperation which in turn conferred survival advantages over other groups.

TL;DR: In this paper, the authors consider the underlying evolutionary motivations for consumption and choice from an evolutionary perspective, highlighting that many consumer choices ultimately function to help fulfill one or more of these evolutionary needs.

TL;DR: It is argued that harm should be redefined as an intuitively perceived continuum, and this redefinition provides a new understanding of moral content and mechanism—the constructionist Theory of Dyadic Morality.

The emotional dog and its rational tail: a social intuitionist approach to moral judgment.
TL;DR: The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached.

Vision: A Computational Investigation into the Human Representation and Processing of Visual Information
TL;DR: Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field of visual perception as discussed by the authors, where the process of vision constructs a set of representations, starting from a description of the input image and culminating with three-dimensional objects in the surrounding environment, a central theme and one that has had farreaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis.
