Alex Crossman, headteacher of the London Academy of Excellence (left) and Jamie from Adolescence (right)The Prime Minister has called for the Netflix drama Adolescence to be shown in schools. His impulse to inoculate boys and young men against the online pandemic of toxic masculinity is laudable.But his recommendation is misplaced.  Adolescence will only serve as a warning if teenage boys at risk of radicalisation recognise the behaviours it portrays onscreen as aberrant and nihilistic.They may not. Indeed, it is likely that many will not.Research warns us against ‘negative social norming’, the risk that education unintentionally normalises the thing it is trying to eliminate.For those engaged in – even on the fringe of – bullying, misogyny and violence, watching Adolescence could positively reinforce those tendencies, while sending other students off in search of the very content the series warns about.
