I'd just like to take this to task for how much supposition is floating around. Early on we are introduced to the idea of snapping via an anecdote. We are given a neuronal hook via something called a 'hypothalamic attack region', which produces rage in rats. Is this region responsible for the opening episode of rage? We have no idea; it is pure speculation to assume it is. All of the subsequent examples (crime, heroism) are imputed to this circuit similarly without evidence. Then we are given a model (LIFEMORTS), which is extended to cover race relations and much else. We are told our thinking is 'tribal'; we are expected to believe this is science, because recall the existence of the hypothalamus attack region! But there is no evidence chaining these three together (neurons, the model, the behavior) - we have zero reason to accept the model view of what happened in Baltimore. It is pure speculation.
