Refer to the adolescence phase of male aspie development. There are both similarities and differences in expression during this phase. The key is that both types become obsessed with performing violence effectively, but neanderthals express this in an emotional, endogenous, and socially primitive way, whereas owl melons express this in an intellectual, exogenous, and socially adaptive way.
When I was an adolescent I was obsessed with martial arts, physical training, and emotional hardness. I watched terrifying and gory movies even though I didn’t like them, because I felt an inner sense of duty to develop a stoic response to stressful situations. My driving instructor remarked during my first drive that “you have the demeanor of an undertaker”, and my public speaking teacher noted that my stress response was the opposite of a normal person’s (speaking more slowly and deliberately). My taste in video games was characterized by heroism and small-group social dynamics, including first-person shooters, RPGs, and adventure games in general. These can all be described as interests inherited from small-tribe hunter-gatherer instincts.
Owl melons have similar interests, but they also have more complex and abstracted interests. They additionally become obsessed with social competition, logistics, economics, politics, and principles of leadership and strategy. I would guess that they feel a duty to put themselves in situation where perception and symbolism matter—like advertising, public relations, etc.—despite their distaste for these things. In college (or a first job out of high school) they will tend to be Sigmas because they are practicing the Game (both PUA and more generally) with an intellectual’s practiced indifference. Their taste in video games will tend more to wargaming, RTS, and business/logistics simulators. These can all be described as interests inherent to a well-bred officer class.
If this is correct, what this correspondence suggests to me is that owl melons came to exist as a class of melons with specific neanderthal expression that found a niche in the military. This would be analogous to the way neanderthals have found a useful niche as geniuses within (begrudging) modern white societies. One testable hypothesis is that owl melons should have a strong hormonal response to independence from male authorities (relative to a control group), marking the end of their adolescence. This would be analogous to orangutan flanges.
