I have a theory that the reason that many different neurological types maintain consistent percentages per capita year after year is that somehow it’s useful for constructing human communities. As an incomplete example, I’m talking about:

  • High functioning sociopaths (cold-hearted leader/organizer types) 4%
  • Bipolar disorder (frequently leaders or very creative) ~2.6%
  • Autism Spectrum (technological and scientific innovation) 1.7%
  • ADHD (novelty generators) 5% to 11%
  • Schizophrenia (visionary thinking in any discipline) 1%

I’m not certain how the predictable gay and lesbian* population percentages factor into this exactly but as a guess, they have historically not been focused on raising children. As a predictable percentage of the population not absorbed in raising families and often positioned as outsiders in their own surrounding cultures, they would almost guarantee the existence of an alternative subculture where they might generate new ideas not approved of by our final group. 3.5% 

Everyone else is good old standard human stock who mostly just want family and security. I think the neurotypical brain which defines this group, is every bit as much a specialized filter as the atypical types mentioned above, it is simply specialized to keep things simple and inside the comfort zone. They respond to social pressure far more seriously than atypicals which makes them a kind of cultural cement. Neurotypical breeders are the low center of gravity for every community that ensures stability. They are neither better than our atypicals, or worse, they are the dominant percentage because life wants a solid base to grow from. There are three structural divisions in this last group. ~90%

  1. Male and female. ( the transgender variations and shadings of male and female are very small in number compared to “standard issue” they might be classed with the gay and lesbian populations for our purposes.  0.3%) There are obvious cultural roles and practical roles determined here. One astounding but well-documented fact is that during and after wars, a higher than average number of boys are born. The mechanism driving this effect has no useful model within current science but the reason for it is easily understood: “I guess we better make a few more boys to cover losses”. Whatever the mechanism is, it perceives large events at a community level… and adjusts via individual pregnancies. Males ~51.9% Females ~49.1%
  2. Progressive vs conservative viewpoint, which is strongly linked to personality type metrics and as I’ve explored elsewhere in this blog their “Tension force” creates the defining zeitgeist of every culture. In a polling in June 2010, 40% of American voters identify themselves as conservatives, 36% as moderates and 22% as liberals, with a strong majority of both liberals and conservatives describing themselves as closer to the center than to the extremes (Wikipedia).
  3. Age-based focus and attitude within the general population. From child to teenager to young adult to middle-aged to elderly there is a predictable staged transition through age-based societal roles***: Student, soldier, young married, worker, settled parents, judgemental elders. In a way, this echoes the division of labor within bee and ant colonies. How do they decide what job to do? As the individual insect ages, it progresses through a series of preset “vocational” roles within the hive. For humans, the most basic example of the age-based behavior difference is the openness of the young to change and the resistant defensiveness of the old. This mechanism makes a cultural shift possible, then limits the amount of change.

According to my half-assed theory, being Neuro-Atypical or sexually atypical is not a random failure to create a normal person. Rather it is a structural role predictably of some benefit to the general population. That would explain why the percentages of these varied types are so reliable. Everyone from the most boring normal person to with wildest transgender bipolar radical conservative has a structural purpose in the diverse needs of the human hive. This points to a real-time reproductive algorithm affecting the population as a whole and somehow sensitive to such temporal events as war. It would be no shock if such a mechanism exists, for it to show other concerns about population balance necessary to keep the community organism in good repair. We see a similar balancing mechanism in other hive creatures. In a sense, it’s like a body generating replacement cells of the right kind as needed.

 


  • * I’m not claiming to have discovered an atypical neurology specific to gays and lesbians. They are here because their population percentage is very consistent over time and they tend to occupy a unique reality niche.
  • ** I’m not mistaking transgender folk for gay or lesbian. I’m just placing them in a sex/gender outsiders group.
  • ***  William Shakespear on this preset aging process:

At first the infant, Mewling and puking in the nurse’s arms; And then the whining schoolboy, with his satchel And shining morning face, creeping like snail Unwillingly to school. And then the lover, Sighing like furnace, with a woeful ballad Made to his mistress’ eyebrow. Then a soldier, Full of strange oaths, and bearded like the pard, Jealous in honor, sudden and quick in quarrel, Seeking the bubble reputation Even in the cannon’s mouth. And then the justice, In fair round belly with good capon lined, With eyes severe and beard of formal cut, Full of wise saws and modern instances; And so he plays his part. The sixth age shifts Into the lean and slippered pantaloon, With spectacles on nose and pouch on side; His youthful hose, well saved, a world too wide For his shrunk shank; and his big manly voice, Turning again toward childish treble, pipes And whistles in his sound. Last scene of all, That ends this strange eventful history, Is second childishness and mere oblivion, Sans teeth, sans eyes, sans taste, sans everything.
