Lying by Asserting What You Believe is True: a Case of Transparent Delusion

This week's post is from Vladimir Krstic (a philosopher at the United Arab Emirates University) on his recently published paper Lying by Asserting What You Believe is True: a Case of Transparent Delusion (Review of Philosophy and Psychology). 

Imagine that I tell you that I believe that I am Hitler but that I am not Hitler since he is dead and I am not. You would probably think that you did not hear me correctly. But, if — upon your request for clarification — I tell you specifically that I believe that I am Hitler but that this is not possible and that, thus, my belief is obviously false, you might think that I am toying with you. Many people, following Moore, think that these claims are absurd.

However, this impression is misleading. One can confidently believe that p and ascribe this belief to oneself, while judging that not-p. This is what happens to transparently delusional people. They suffer from a delusional belief, they correctly ascribe this belief to themselves,but they also judge that their belief is false. There are also cases of non-pathological yet transparently irrational beliefs that people correctly ascribe to themselves while judging that the opposite proposition is true.

In this paper, I argue that analysing this condition generates many important insights regarding the nature of lying and sincerity. Most obviously, it suggests that people can lie by asserting propositions they confidently and consciously believe are true as long as they concurrently judge them to be false. More importantly, it suggests that the judgement about whether p and the self-ascribed belief about whether p can come apart and that judging that pdoes not entail believing that p. These hypotheses allow us to better understand many phenomena that seem paradoxical, like some cases of self-deception that involve a tension between the person’s professed belief and her behaviour.

Two ‘faults’ in one’s thought-evaluation processes explain transparent irrationality. Briefly, people evaluate their thoughts in two simple steps. In the first step, they purge the thought of all contextual or narrative associations (e.g., emotional importance) — the so-called thought-decontextualisation. Once the thought is decontextualized, the person can effectively run it through different domains of reality to test it for consistency (i.e., to see how probable it is considering various aspects of the world) — the so-called reality test (the second step). Athought that passes both steps is marked as correct.

Transparently irrational thoughts are caused and maintained by an error in one or both of these steps; as a result, the thought passes the test when it should not. A step 1 error is when the thought does not get decontextualized properly and certain subjective associations interfere with its reality-testing. Thus, some parents cannot believe that their child is abusing drugs even while looking at its bong. A step 2 error is when the thought does not get rendered through the relevant domain of reality and so it is never put together with the judgement to the contrary in a way that would result in the thought’s revision. I consciously believe that I am Hitler and judge that I am not Hitler because, due to a step-2 failure, I cannot realize that my judgement is a reason to revise or abandon my belief.

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...

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...
