Humour: A Very Short Introduction, by Noël Carroll (Oxford)
Trying to explain a joke has long been considered a paradigm of pedantic futility. That hasn’t stopped thinkers through the ages erecting vast and subtle theories of comedy. But none of them had brain-scanners. Perhaps cognitive neuroscientist Scott Weems can explain once and for all why Louis CK is funny and David Cameron isn’t.
Very early on, the book’s ultramodern tone is set. We are invited to agree that no one could ever have properly known anything about a complex sociocultural phenomenon before lab volunteers started being rolled gently into fMRI tubes. “Humour has some very clear ingredients,” Weems says, “ones that science is just now beginning to reveal.” That sounds exciting. Let’s see what they are. When people in scanners found certain cartoons funny, Weems explains, various parts of their brains increased in activation, and those parts are associated with the “dopamine reward circuit”. What does this reveal to us about the nature of humour? Sweet FA, unless it had never occurred to you that it is pleasurable to be amused. The “dopamine reward circuit”, according to other studies, also gets a jolly workout from cocaine, chocolate and video games. So: nothing new about humour here.
