One highly important aspect of the decline in intelligence that has been occurring now for several decades which is often overlooked is the impact of the magnitude of fertility itself. Specifically, high rates of fertility by themself
are sufficient to allow for another roll of the dice with the possibility of conceiving a genius and high fertility rates also provides the environment to allow skills to develop. It is quite inspiring to recognize the brilliance
that emerged in the 20th Century due precisely because of this population boom and of the creation of achievement niches this allowed. Without question all these additional billions of people created an all time high in the achievement
of the human species during the last century. Peak humanity. Unsurprisingly it can now be seen as a golden age of human accomplishment.
Yet, here we are now and the party is over. Whereas in the 20th Century life seemed to progressively reach new heights, what we can see all too clearly in the 21st Century is reaching progressively new lows.
It should now be abundantly obvious to anyone paying attention that this is true. We have entered into long-term psychometric decline for the first time in centuries. Life is no longer magically getting better and better.
The fertility collapse in nations such as Japan means that there is now only ~ 50% of the psychometric potential as existed 50 years ago with ongoing decline for as far as the eye can see.
Western nations achieved near all time absolute fertility numbers in their native populations decades ago with ongoing decline ever since. The fertility collapse that has emerged in most Western nations over the last
few decades along with the dysgenic trend (by cognitive ability) has created a powerful long-term anti-psychometric force. Class based arguments that would try and suppress those who are disadvantaged
within the Western nations from reproducing are not overly helpful as this merely has allowed migrants of even lower cognitive potential to replace existing native populations. It is important
to realize that in fact, those near the bottom of our social ladder typically have children with higher intelligence than their own, while those near the top of the social ladder typically have children with lower
intelligence than their own. This regression to the mean results in children within a given population from those of all backgrounds with highly similar cognitive ability. Class conflict that attempts to hinder
this internally generated solution to the fertility problem merely compounds the social decline.
The below figure shows an interesting geographic expression of the effect of demographics on skill level in the community. Apparently there is a minimum population density that is needed in order tor
higher order cognitive ability to flourish. This transition to modern human behavior required a density of ~ 3.2714 × 10−4km−2. Article below describes how it is these demographic forces that can explain
emergence of modern human cognitive behaviors more so than even cognitive ability directly. Interestingly, the example of Tasmania is provided in which their population also went into demographic decline
and upon first contact with modern European explorers had devolved back to a near cave age existence in ~1700. Psychometric collapse is not some ridiculous fiction; it has been clearly documented
in past research.

An obvious and highly powerful counter-strategy that could be applied to reverse existing psychometric collapse is embryo selection. Boosting population intelligence by the 3 IQ that has been shown to be possible would rapidly reverse the current decline.
It would in fact restore the golden age of humanity that we had until recently taken for granted. Other reproductive technologies that are already within sight could greatly amplify simple embryo selection. If anything we are now on the very edge of a dramatic enhancement in human cognitive ability. This is all the more likely as we sink deeper and deeper into the cognitive ability abyss that we are now stuck in. People do not want this future of decline for their children and grandchildren: current reproductive technology could ensure that this will not be our fate.

The live action simulation models how population density helps to build up community skill level.
(OK forum software is not allowing me to post the figure using any file format just go to the url and see the live action.)
