Read it. Think it through. I don't think it's unreasonable. Adaptive, evolved capacities in extremis relative to the immediate environment can be very maladaptive. Still, it isn't an idea we should run with. It's more on the order of interesting speculation, much the way I think about how obssessions, compulsions and hypervigilence might be extreme manifestations of adaptive capacitites that might improve survival in environments fraught with danger.
I'll leave future investigaton to the neuroanthropologists.
