CRASSH Moral Psychology Conference



On 9th October CRASSH organised a Moral Psychology Interdisciplinary Conference in Cambridge, featuring keynote talks, panel discussions and discussion groups. This is a brief report on the sessions in which I participated.

The first session was a panel symposium with Josh Greene (Harvard) and Molly Crockett (Oxford) on the future of moral psychology chaired by Richard Holton. Josh started discussing the assumption in popular culture and the media that there is a “moral faculty” where all moral beliefs and decisions can be found, somewhere in the brain. But this is a myth according to him: morality is like a vehicle. “Vehicle” is a category, but what makes something a vehicle is not its internal mechanics. What makes something a vehicle is its function. Same with morality. If morality is a thing, people who study morality are interested in its function. The processes, operating principles and behavioural patterns involved in moral thinking are not distinct to morality.

Molly made the point that no study so far has examined in the same sample social and non-social computation, moral and non-moral decision-making in the scanner, so there is still room to argue that there is something distinctive about morality. For Josh, morality is about cooperation and thus it is predominantly social. There may be a distinction between social and non-social pathways, but not about moral and non-moral over and beyond the social.

But are there discreet emotions? Probably not, emotions as we know them are probably just a blend of different elements (e.g., guilt is a mixture of arousal and fear). Molly argued that the peculiarities of guilt (how we feel about it, in what circumstances it emerges, etc.) partially depend on our way of living, and would manifest differently in a radically different culture. For both Molly and Josh, morality is about warmth and competence, where warmth is more important than competence.

The discussion then moved to how we learn. There are different systems for learning that are psychologically dissociable.
  • Goal-directed/model-based system: decisions and actions are based on a model of the world (controlled); more reason-based and cold. 
  • Model-free system: decisions and actions themselves take on positive or negative value (controlled); more emotional as it relies on affective weighing. 
  • Pavlovian system: approaching rewards and avoiding punishment (automated). 
Consequentialist thinking tends to be more commonly adopted as part of the goal-directed system, and deontological thinking tends to be favoured by the the model-free system.

In the next session, Jill Craigie (King’s College London) and I talked about responsibility and control, in two different contexts. Jill (pictured below) focused on mental capacity and legal capacity in addiction, and in particular alcohol dependance. I focused on responsibility over actions motivated by delusional beliefs in people affected by schizophrenia, and responsibility for adopting delusional beliefs.



Talking about mental capacity and its assessment, Jill asked whether cognitive tests are sufficient to judge whether someone can be guided by reason. Are such tests contrued in a way that is sufficiently broad to assess all the relevant capacities? Addiction does not fall under the Mental Health Act but it falls under the Mental Capacity Act. Among the capacities included in the notion of mental capacity, there is the capacity to make one’s own treatment decisions. Criteria for mental capacity are the ability to understand, retain and weigh up relevant information, and make a decision on the basis of that information.

Jill reported a case of Ms X who was suffering from alcohol dependance and anorexia. She had a number of involuntary hospital admissions. The court considered her capacity both in relation to alcohol dependance and anorexia. They decided that she lacked capacity when it came to her anorexia (e.g., she lacked the capacity to weigh information about the consequences of treatment, and the compulsion not to eat was too strong for her to ignore), but she had capacity in relation to her alcohol dependance (e.g., she was choosing when and what to drink, and her drinking was responsive to events).

Although alcohol dependence could fall under the Mental Capacity Act, in fact it has been judged not to compromise mental capacity in England and Wales (but interestingly it has in US and Australia). It is not clear what justifies treating anorexia and alcohol dependence differently in some of these cases. Anorexia is seen as a habit one cannot break and implying an inability to weigh consequences of not eating. But alcohol dependence is not seen in the same way.

I discussed some case studies showing that the presence of psychotic symptoms in general and delusions in particular should not rule out by default that a person is responsible for behaviour that is motivated by such symptoms. I also referred to the high-profile case of Breivik.

After the lunch break, I attended the discussion group on psychopathy and moral motivation, led by Marion Godman (University of Helsinki). Marion (pictured below) introduced one of the main issues surrounding psychopathy, the high prevalence of psychopathic traits in people who are incarcerated for serious, violent crimes. She discussed the empirical finding according to which psychopathy is associated with spontaneous as opposed to reactive aggression.




From the data, she moved on to the analysis of different interpretations, and talked about a recent debate about whether the behaviour of people of psychopathy should be regarded as ‘mad’ or ‘bad’. Marion found that both ways of categorising psychopathy are characterised by unattractive consequences. An intense discussion followed, where some interesting parallales were made between psychopathy and autism (the former being associated with a compromised capacity to be motivated by punishment, and the latter with a compromised capacity to be motivated by rewards).

The conference was very stimulating and I had the pleasure to meet many young researchers in philosophy, psychology, and neuroscience, testifying to the genuinely interdisciplinary nature of the event.

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.

Rationalization: Why your intelligence, vigilance and expertise probably don't protect you

Today's post is by Jonathan Ellis , Associate Professor of Philosophy and Director of the Center for Public Philosophy at the University of California, Santa Cruz, and Eric Schwitzgebel , Professor of Philosophy at the University of California, Riverside. This is the first in a two-part contribution on their paper "Rationalization in Moral and Philosophical thought" in Moral Inferences , eds. J. F. Bonnefon and B. Trémolière (Psychology Press, 2017). We’ve all been there. You’re arguing with someone – about politics, or a policy at work, or about whose turn it is to do the dishes – and they keep finding all kinds of self-serving justifications for their view. When one of their arguments is defeated, rather than rethinking their position they just leap to another argument, then maybe another. They’re rationalizing –coming up with convenient defenses for what they want to believe, rather than responding even-handedly to the points you're making. Yo...

A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind

Today's post is by  Karen Yan (National Yang Ming Chiao Tung University) on her recent paper (co-authored with Chuan-Ya Liao), " A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind " ( Synthese 2023). Karen Yan What drives us to write this paper is our curiosity about what it means when philosophers of mind claim their works are informed by empirical evidence and how to assess this quality of empirically-informedness. Building on Knobe’s (2015) quantitative metaphilosophical analyses of empirically-informed philosophy of mind (EIPM), we investigated further how empirically-informed philosophers rely on empirical research and what metaphilosophical lessons to draw from our empirical results.  We utilize scientometric tools and categorization analysis to provide an empirically reliable description of EIPM. Our methodological novelty lies in integrating the co-citation analysis tool with the conceptual resources from the philosoph...
