Why people deceive themselves

A philosophy team from Ruhr-Universität Bochum (RUB) and the University of Antwerp analysed the role self-deception plays in everyday life and the strategies people use to deceive themselves. In the journal Philosophical Psychology, Dr. Francesco Marchi and Professor Albert Newen describe four strategies used to stabilise and shield the positive self-image. According to their theory, self-deception helps people to stay motivated in difficult situations. The article was published on 6 January 2022.

Four strategies of self-deception

"All people deceive themselves, and quite frequently at that," says Albert Newen from the RUB Institute of Philosophy II. "For instance, if a father is convinced that his son is a good student and then the son brings home bad grades, he may first say that the subject isn't that important or that the teacher didn't explain the material well." The researchers call this strategy of self-deception the reorganisation of beliefs. In their article, they describe three more frequently used strategies that come into play even earlier in order to prevent unpleasant facts from getting to you in the first place.

This includes selecting facts through purposeful action: people avoid places or persons that might bring problematic facts to their attention, such as the parent-teacher conference. Another strategy is to reject facts by casting doubt on the credibility of the source. As long as the father hears about his son's academic problems only indirectly and does not see the grades, he can ignore the problems. The last strategy is what Newen and Marchi call generating facts from an ambiguous state of affairs: "For instance, if the kind mathematics teacher gently suggests that the son is not coping, and the father would have expected a clear statement in case of difficulties, he may interpret the considerable kindness and the gentle description as a positive assessment of his son's abilities," Francesco Marchi elaborates on the example.

The researchers describe all four strategies as typical psychological thinking tendencies. Self-deception is neither unreasonable nor detrimental to people in the short term, but always in the medium and long term. "These are not malicious ways of doing things, but part of the basic cognitive equipment of humans to preserve their established view of themselves and the world," says Newen. In normal times with few changes, the tendency to stick to proven views is helpful and also deeply rooted in evolution. "However, this cognitive tendency is catastrophic in times of radically new challenges that require rapid changes in behaviour," adds the Bochum researcher.
