not enough
like children, teenagers are not adults, and road anger is pretty much in the realm of instinctual behavior. but why do some people institutionalize the torture of captives, engineer wars of discretion, and create toxic mortgages? those are not instinctive behaviors; they require long periods of planning and execution by adults. and why do some nations specialize in them, but not others? do some populations have more genes of one sort than others? is history therefore a matter of genes, distributed at random? it seems that many factors not considered by nicholson are at work.
