Genetic Drift

An earlier post asked "Are there more crazy people now?" and the body of the text focused on how the pressures of environmental "triggers" have increased for most causes.

The genetic portion which is responsible for 60%-to-85% of the cases was not discussed in that post.

Are more people carrying "crazy-genes" then they did in the past?

The short answer is "yes".

Life was a constant struggle for sane, well adjusted people in the slums of Limerick, Liverpool and Hamburg. It was fatal for crazy-people.

As recently as 1900 in developed countries like Ireland, England and Germany, if your mother was crazy you were probably not going to live to see your first birthday.

If you were a crazy-woman, your best chance of getting married was to get pregnant and "trap" an impulsive man. There was  a pretty good chance he was also crazy or was an alcoholic.

As her child, your best hope for survival was to be placed in an orphanage, which in turn greatly reduced your chances of marrying and producing children.

In total, crazy-genes had a high probability of "dead-ending". In those days the pool of crazy people resulted from random meetings of recessive genes or in new mutations.

Flash-forward to the permissive, Welfare-State

Anecdotally, one of our local characters who was called "Homeless Girl" had five children before age 25 and they were all removed by Child Protective Services because: 

  • She was homeless
  • She was addicted to drugs and could not care for them

Eventually, she O.D.ed in the bathroom of a fast-food restaurant.

The average woman in the United States has her first child at age 27-1/2 years.

That means that this crazy-woman had FIVE children before the average, not-crazy woman had her first. And all of the crazy-woman's children survived.

This is happening (with minor variations in the details) all over the United States and Europe. 

Numerically, that means that back when "crazy-genes" self-extinguished we experienced a rate of approximately 5% seriously crazy people. Now the crazy-people genes are subsidized rather than exposed to Darwinian selection and the numbers are growing much faster (due to high risk behaviors) than the numbers of not-crazy people.

    1. At least crazy calves make decent beef.

      Like the rooster I processed two days ago for attacking my grandchild.

      He's nicely cooked up, and his carcass made into a nice base for chicken soup.

      Crazy people are not so useful (and far more dangerous).

  2. Factual. Pity we both know folks that would argue how unkind we are to notice such and probably call us Nazi's or such for it.

    Or as Grandmom used to say if you feed stray cats they breed more. If you don't they STARVE to death (and fail to breed).

    OH the Humanity lost by allowing cute little cats to starve...

    We've done the same with the shiftless and protected the criminals in the current legal system.

    And we wonder why this sort of thing is happening:

    Sickening footage shows the moment an elderly Seattle woman had her eye gouged out after she was randomly bashed in the head with a board by a “notorious” repeat-offender thug.

    Jeanette Marken, 75, was permanently blinded in her right eye after the alleged perp, Fale Vaigalepa Pea, 42, struck her with a piece of wood riddled with bolts and screws earlier this month, KOMO reported.

    The horrifying clip from downtown Seattle captured the attacker approaching the unsuspecting woman from behind as she waited patiently to cross the street just outside the King County Courthouse.

    Seems none of the major news carried this.

    Isaiah 5 has something to say about that:

    Woes to the Wicked
    20Woe to those who call evil good and good evil, who turn darkness to light and light to darkness, who replace bitter with sweet and sweet with bitter. 21Woe to those who are wise in their own eyes and clever in their own sight.…

    Pray for wisdom.

  3. Another place crazy bubbled up was our frontier. There is not a lot of status to tracing your lineage to a French trapper. They were frequently violent social outcasts with a gift for being a step ahead of the law. Roger

  5. 25% of North American women are on prescription psychotropic drugs, though. Is it genetics? Or stress/trauma induced? How successful is medication?
    If it is stress/trauma induced… I don’t get it. I come from a family of angry liberal women and … I do not understand the source of their rage and unhappiness.
    Is it a sex linked genetic illness? Kinda like heamophilia?

  6. Disproportional retribution may cause fear enough to give pause to other miscreants. Jail time isn't sufficient. Cut off a hand of thieves. Cut off penises for (male) sex offenders. Batter to death that POS in Seattle with sticks having nails embedded. I guess I'm not much of a Christian.
