Disgust is characterized by a remarkably diverse set of stimulus triggers, ranging from extremely concrete (bad tastes and disease vectors) to extremely abstract (moral transgressions and those who commit them). This diversity may reflect an expansion of the role of disgust over evolutionary time, from an origin in defending the body against toxicity and disease, through defense against other threats to biological fitness (e.g., incest), to involvement in the selection of suitable interaction… 
Developing Disgust: Theory, Measurement, and Application
Disgust is a complex and uncharacteristic emotion. Despite being frequently classified as a “basic” emotion, disgust has a wide range of elicitors, many competing functional theories, and a

Social neuroscience of disgust
Findings on the social neuroscience of disgust have a direct bearing on the understanding of the roles of disgust in shaping human and nonhuman social behavior.
Things rank and gross in nature: a review and synthesis of moral disgust.
Evidence is reviewed that moral transgressions do genuinely evoke disgust, even when they do not reference physical disgust stimuli such as unusual sexual behaviors or the violation of purity norms, and 3 models of moral disgust are described, each of which aims to provide an account of the relationship between moral and physical disgust.
The Relationship Between Ideology and Disgust Sensitivity
The aim of the current paper is to examine the association between ideology and disgust sensitivity. Studying disgust offers psychologists an opportunity to assess how judgments have evolved over
Temporal Dynamics of Disgust and Morality: An Event-Related Potential Study
The results implicate that physical disgust emotion may not be necessary for people to make moral judgments, and suggest that some of the authors' moral experience may be more fundamental to their survival and development, as humans spend a considerable amount of time engaging in social interaction.
Consumption, contact and copulation: how pathogens have shaped human psychological adaptations
It is illustrated how low expected values of consumption and contact as well as low expected sexual values can be used by the moral psychology to provide multiple causal links between disgust and morality.
Does inappropriate behavior hurt or stink? The role of pain and disgust on moral decisions
Our study aimed to elucidate if moral cognition is grounded in sensory-specific aspects of disgust or in representations of supramodal dimensions (such as valence or arousal) that we also find in
Exploring the Emotion of Disgust: Differences in Smelling and Feeling
Disgust evolved to motivate humans away from disease cues and may heighten discernment of these cues. Disease cues are often best perceived through our sense of smell, however very few studies have
Oxytocin, social factors, and the expression of conditioned disgust (anticipatory nausea) in male rats
It is suggested that OT may play a role in the modulation and expression of socially mediated conditioned disgust in rats, which is a learned response observed following chemotherapy treatment.


Disgust as a disease-avoidance mechanism.
The authors find strong support for a disease-avoidance account of disgust and suggest that it offers a way to bridge the divide between concrete and ideational accounts of disgust.
Infection, Incest, and Iniquity: Investigating the Neural Correlates of Disgust and Morality
Support is provided for the view that the biological response of disgust is intimately tied to immorality, and it is demonstrated that there are at least three separate domains of disgust, to suggest strongly that morality is not a unified psychological or neurological phenomenon.
Evidence that disgust evolved to protect from risk of disease
Evidence is provided that the human disgust emotion may be an evolved response to objects in the environment that represent threats of infectious disease.
Body, Psyche, and Culture: The Relationship between Disgust and Morality
"Core disgust" is a food related emotion that is rooted in evolution but is also a cultural product. Seven categories of disgust elicitors have been observed in an American sample. These include
The Moral Affiliations of Disgust: A Functional MRI Study
Results indicated that emotional stimuli may evoke pure disgust with or without indignation, and these different aspects of the experience of disgust could be elicited by a set of written statements, and pure disgust and indignation recruited both overlapping and distinct brain regions, mainly in the frontal and temporal lobes.
Microbes, mating, and morality: individual differences in three functional domains of disgust.
This work investigates a 3-domain model of disgust and introduces a new measure of disgust sensitivity, which shows predictable differentiation based on sex, perceived vulnerability to disease, psychopathic tendencies, and Big 5 personality traits.
Dirt, Disgust, and Disease: Is Hygiene in Our Genes?
Anthropologists have long puzzled over why certain objects and activities are avoided, reviled, or proscribed in many cultures, but as Reinhart (1990) suggests, a full explanation remains elusive.
In Bad Taste: Evidence for the Oral Origins of Moral Disgust
It is found that immorality elicits the same disgust as disease vectors and bad tastes, and all three states evoked activation of the levator labii muscle region of the face, characteristic of an oralnasal rejection response.
Moral hypervigilance: the influence of disgust sensitivity in the moral domain.
It is proposed that highly disgust-sensitive individuals would be particularly repelled by exposure to transgressors and, consequently, would think and behave in ways aimed at reducing the risk of such exposure occurring--a syndrome the authors call moral hypervigilance.
A perspective on disgust.
The ontogeny of disgust, which the author believes develops during the first 8 years of life, is considered and the idea that feces, the universal disgust object, is also the first is explored, and the mechanisms for the acquisition of disgust are examined.
