Abstract:
Self-harm among young people is rising worldwide and spreads through peer networks. We apply Tinbergen's four questions - a framework from evolutionary biology applicable to all biological phenomena - to argue that group self-harm may be an ancient ritual process that has become dangerous when severed from the cultural structures that once contained it.
