Selection pressures can produce significant changes in a few generations
Hi, Joseph. I am not writing on the topic of the post.
Recently I tried to open the links you referred to on twitter (about the dysgenia of female sexual selection):
But in fact, both links turn out to be non-working. What happened? Did you delete the articles? I would really like to read them.
To appreciate how much our knowledge has been distorted by the propaganda approved by the capitalist class, see the essay:
The link between genetic inheritance and "IQ" has been used by many as a way of ranking individuals in a hierarchy of "intelligence," and then utilizing that "knowledge" to form social or political policies. But modern anthropology has advanced to the level of recognizing that genetic inheritance plays only a subordinate role in the advancement of human creativity, ingenuity, and progress. The basic source of human progress is to be found in the cultural ability of human groups to absorb knowledge from the previous generation, and pass on this knowledge to succeeding generations. From generation to generation human societies have absorbed and often supplemented their modes of behavior, thus achieving higher levels of social cohesion and individual performance. This anthropological knowledge is explained in Joseph Henrich's book "The Secret of Our Success."
Interesting. I agree with you that selective pressures work much faster than most people realize. I even mention it in my book “From Poverty to Progress.”
I am skeptical, however, that a slightly lower number of people over 130 IQ will lead to lower rates of innovation. Very few people over 130 innovate anything of historical importance.
The common phenomena of simultaneous innovation by different people at the same time suggests that innovations are waiting to happen, and it is somewhat of a coincidence who gets the job done. I believe there will be plenty of people over 130 for the foreseeable future.
Now if we had a 20-30% drop, that might be a completely different story. I hope that we never get to that.
