Third, the humour we have seen in response to London and Manchester is also important. Humour has been linked to evolutionary responses where violence is no longer appropriate – humour enables us to ‘let off steam’ and redirect anger in more productive and less dangerous ways. However, it is more than that, humour is a positive emotion, not merely a ‘coping’ mechanism, one which creates social bonds. Humour also helps makes sense of the world; it talks truth to power, and operates as an act of resistance. Therefore, hashtags such as #ThingsThatGetBritainsReeling,#ISISClaims, and the mocking of the idea that Londoners are ‘in fear’ (and never spilling a pint) are important to resilience. Humour has also been used as a deliberate strategy to productively talk about, and teach young people about issues such as terrorism. The film Four Lions was a successful comedic vehicle that challenged stereotypes around terrorism and radicalisation.
