People are continually alert to the odd - we have a better memory for things that seem different from others. We will pay more attention to strange events than equally bad normal events. So the more used we become to a 'bad thing', the less we are unsettled by it. Which might mean that the impact of terrorism is diminished the more common it becomes. Michael Blastland explores this concept, with Nick Chater.

First broadcast on The Human Zoo, 26 July 2016.
