An alternative theory for melonheads that’s floating around out there is that melonheads are merely the gracilized modern form of neanderthal-sapiens hybrids, probably arising from the Amud strain. This theory has a couple of strong points in its favor.
The family resemblance is uncanny, which is a fact any theory of neanderthals and melonheads has to contend with. As Obadiah once pointed out, melonheads aRe Real autists when you get down to it. It could well be that the distinction between machiavellian sociopathy and what Hans Asperger called “autistic psychopathy” may be a more of a spectrum than a categorical difference. The genetic distance between neanderthals and modern humans could serve to produce predation (as I’ve speculated in the Denisovan-Neanderthal hybrid theory of Melonhead origins), culminating in apex predators like Diana Mitford. Maybe charisma is more of a learned skill than an instinctual aptitude, and some autists specialize in human systems while others pursue engineering systems. There’s also a physiognomic and geographical overlap where the Swiderian/Brunn race appears to represent the in-between phenotype:
I don’t think this theory is true–in fact, I believe that the conflation of sociopathy and Asperger’s is a negative transference ploy for sociopaths to claim the accomplishments of genius and group-benefiting altruism and escape the consequences of their self-glorifying intragroup predation. But even so, the theory needs a name, it needs to be considered seriously, and if it’s wrong this needs to be demonstrated.
