We asked Professor Bruce Hood (Psychology Department, University of Bristol), to comment on his current work and ideas that have influenced him…

Which of your own ideas have you been thinking about most recently?
In [my new book] SuperSense, I talk about psychological essentialism as the basis for a common supernatural belief where we attribute some invisible property to the material world. For example, people are repelled by the thought of wearing a killer’s cardigan. I think of this as moral contagion but critics simply dismiss this as a learned association, that is, avoid bad things. Somehow learned association doesn’t capture the repugnance generated by the cardigan example and so I struggle to keep finding better ways to explain it.

What idea of someone else has made most impact on you recently?
After a previous Bristol Festival of Ideas event, Steven Pinker told me about the work of economic psychologist, Philip Tetlock over dinner. Tetlock proposes that societies have sacred values to generate group cohesion and that individuals who violate these sacred values are ostracised.This idea forms a core explanation in why our ‘SuperSense’ is so common and how it can make sacred things profound by evoking the supernatural.

What is the most important book/article of ideas that everyone shouldread and why?

I have to say that Richard Dawkins’ The Selfish Gene changed my thinking for ever and set me out on the path of behavioural science.
