30 minutes long. Broadcast on Friday 30/7, 11am as part of a series of conversations called The Spark, presented by Helen Lewis.
Karen Stenner is a former academic, now independent consultant, who has researched authoritarianism. She thinks there is a genetic/heritable predisposition towards this in about a third of the population, and it doesn't correlate to having right or left-leaning political views, or being of a conservative disposition. A lot of it is about being afraid of difference and diversity, not coping well with complexity and ambiguity, and lacking the trait of 'openness to experience'.
She mentioned in passing that some extremely left-wing people and others with very liberal views can be authoritarian because they are convinced they are right and therefore divergence from their world view must be punished. This rings true for me. Many of the young fanatics on Twitter on any of a range of subjects are incredibly intolerant of difference, and as we know if anybody puts a foot wrong on anything they must be 'cancelled'.
