PERFECT Year Two: Ema

Ema Sullivan-Bissett



In this post I give an overview of what I did as a Research Fellow in the first year of project PERFECT, as well as my plans for the coming year.

My research for the duration of my time working on PERFECT will focus on belief. Last year, Lisa and I worked together on three papers. The first, together with Matthew Broome and Matteo Mameli, was on the moral and legal implications of the continuity between delusional and non-delusional beliefs. The second, together with Rachel Gunn, was on what makes a belief a delusional belief. The third paper was on the status of beliefs from fiction and the teleological account of belief.

My main focus this year though was on defending the one-factor account of monothematic delusion formation. According to this view, the only abnormality we need to appeal to in order to explain why a subject comes to hold a delusional belief, is the anomalous experience she has. We do not need to appeal to any abnormal deficit or bias in the subject’s mechanisms of belief production or belief evaluation, since the psychology involved in these processes is within the normal range. I have worked on defending this view via an investigation into alien abduction belief. My view is that the delusion formation debate can be informed by this phenomenon. Last October we published my interview with Max Coltheart on this topic, split into two parts: the first on delusion formation, and the second on alien abduction belief.

Also this year, Lisa and I organized an event at the Arts and Science Festival in Birmingham on Sight, Sound, and Mental Health. Here I gave a short talk entitled 'A Strange Encounter: Explaining Alien Abduction Belief'. Project PERFECT also sponsored the Philosophy of Psychology strand at the mentoring and networking workshop for women in philosophy which I co-organised (reports from the workshop were published on the blog here and here). This strand featured Imperfect Cognitions network members Hanna Pickard (mentor) and Anna Ichino (mentee) discussing Anna’s paper which argued for a non-doxastic account of religious attitudes (a topic Anna has written on in a post for Imperfect Cognitions).

Last year I was research posts editor for this blog, commissioning and publishing posts every Tuesday, and I’ll continue to do this in the year to come. Do get in touch if you have ideas for blog posts on your recent research!

In the coming year I want to focus on three things. Firstly, I will continue working on defending the one-factor account of delusion formation, and in particular looking at the implications a successful defence of this account has for certain philosophical views of perception and the relationship between belief and truth.

Secondly, I want to work on the relationship between accounts of delusion formation and epistemic innocence, since I think that if delusions are epistemically innocent, as Lisa has argued (here and here), this might be something which all sides of the delusion formation debate can accept.

Finally, I want to think about the biological function of beliefs about epistemic normativity. My thought is that such beliefs are biologically useful, but not as an approximation to truth, since I think they are false. I’ll be developing this idea in time for presentation at our workshop on False but Useful Beliefs in February next year.

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...
