The mental signature for extremism across the board is a blend of conservative and dogmatic psychologies.

Psychologists found that conservatism is linked to cognitive “caution”: slow-and-accurate unconscious decision-making, compared to the fast-and-imprecise “perceptual strategies” found in more liberal minds.īrains of dogmatic people are slower to process perceptual evidence, but they are more impulsive personality-wise. The study also maps the psychological signatures that underpin fierce political conservatism, as well as “dogmatism”: people who have a fixed worldview and are resistant to evidence. This combination of cognitive and emotional attributes predicts the endorsement of violence in support of a person’s ideological “group”, according to findings published in the journal Philosophical Transactions of the Royal Society B.

These mental characteristics include poorer working memory and slower “perceptual strategies” – the unconscious processing of changing stimuli, such as shape and colour – as well as tendencies towards impulsivity and sensation seeking.

A new study suggests that a particular mix of personality traits and types of unconscious cognition – the ways our brain takes in basic information – is a strong predictor for extremist views across a range of beliefs, including nationalism and religious fervour.
