Perpetrator Disgust

Ditte Marie Munch-Jurisic is a research associate at the Moral Injury Lab, University of Virginia and a Teaching Associate Professor at the University of Copenhagen. In this post, she tells us about her new book, Perpetrator Disgust (OUP 2023).




What is the significance of our gut feelings? Can they disclose our deep selves or point to a shared human nature? My book identifies and analyzes the phenomenon of “perpetrator disgust”. Across time and cultures, soldiers who participate in war crimes sometimes feel ill. They start to shake, feel nausea and sometimes even retch and vomit. As a philosopher, I’ve been interested in the many moralized interpretations that scholars and journalists have applied to the phenomenon.

In a nutshell, many have thought that such reactions demonstrate a sort of bodily morality, a physical revolt against the act being committed. But such interpretations are often wrong, especially when grounded in nativist ideas about morality and human emotions. As an alternative explanation, I draw on recent developments in the study of emotions to detail a comprehensive portrait of the phenomenon. I argue for a contextual understanding of human emotions as biological templates that can be hitched to a range of different values and morals.

In every culture, the pedagogy of disgust draws subtle lines of demarcation between us and them: Who should we care for? Who is repulsive and unworthy of concern? As revealed by the recent surge of research in implicit biases, feelings of disgust and discomfort can convey internalized moral values, including values that we may not endorse or believe in, even values we have forgotten about.

My central claim is that, in such cases, our feelings have merely a signaling function: they point toward some transgression of internalized values but do not necessarily reflect a moral judgment. Our feelings may make us aware that something is amiss before we are able to put words to the discomfort, but the bodily feeling itself does not entail a moral evaluation (though it may influence and even distort whatever judgments, decisions, or motivations that follow it). The book considers numerous examples to demonstrate the operation and complexities of this process.

The dominant trend shows that most soldiers are able to overcome the initial shock of killing and adapt to their new circumstances—and this applies even to soldiers who experience perpetrator disgust with explicit feelings of compunction. Soldiers who are altogether unable to cope with killing or who explicitly refuse or protest the atrocities are a rare, anomalous set. Even when a soldier can be said to feel some empathic concern for a victim, the specific context constrains the range of available actions in response to their empathetic impulse; often, the soldier’s actions become more atrocious with time.

There is thus no inherent direction or moral value in visceral feelings of disgust or horror. Through conditioning, the bodily capacity for such reactions can be molded in many different directions, to many different purposes, depending on ideological and moral circumstances. Our physiological reactions and gut feelings are biological templates onto which societies and circumstances imprint their particular values. Instead of reflections of morality, nature, or a revelation of our true self, gut feelings speak primarily to the facts of our time and place.

Delusions in the DSM 5

This post is by Lisa Bortolotti. How has the definition of delusions changed in the DSM 5? Here are some first impressions. In the DSM-IV (Glossary) delusions were defined as follows: Delusion. A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith). When a false belief involves a value judgment, it is regarded as a delusion only when the judgment is so extreme as to defy credibility.

Motivated Reasoning in Science

Today's post is by Josh May (University of Alabama, Birmingham). In this post, he talks about one of his papers published in Synthese and entitled " Bias in Science ". Josh May Much discussion of the replication crisis in science has focused on the social sciences, particularly psychology. A common narrative is that the social sciences are particularly susceptible to powerful biases, such as moral and political ideology. I argue instead for a parity thesis: all areas of science are subject to bias, through the general psychological mechanism of motivated reasoning . This provides a unified framework for understanding how values influence the entire scientific enterprise. The scientific process involves numerous decisions that can be influenced by one's values--including moral, political, and prudential values--which manifest as goals or motivations. A researcher wants badly, say, to publish in a prestigious journal in order to either advance her career or maintain ...

Models of Madness

In today's post John Read  (in the picture above) presents the recent book he co-authored with Jacqui Dillon , titled Models of Madness: Psychological, Social and Biological Approaches to Psychosis. My name is John Read. After 20 years working as a Clinical Psychologist and manager of mental health services in the UK and the USA, mostly with people experiencing psychosis, I joined the University of Auckland, New Zealand, in 1994. There I published over 100 papers in research journals, primarily on the relationship between adverse life events (e.g., child abuse/neglect, poverty etc.) and psychosis. I also research the negative effects of bio-genetic causal explanations on prejudice, and the role of the pharmaceutical industry in mental health. In February I moved to Melbourne and I now work at Swinburne University of Technology.  I am on the on the Executive Committee of the International Society for Psychological and Social Approaches to Psychosis and am the Editor...
