Global enstupidation

Forget the myth of progress. The entire world is literally getting dumber every day:

Wherever you look: junk science, universities corrupted with bogus “studies” departments, politicians peddling discredited nostrums a moment’s critical thinking reveals to be folly, an economy built upon an ever-increasing tower of debt that nobody really believes is ever going to be paid off, and the dearth of major, genuine innovations (as opposed to incremental refinement of existing technologies, as has driven the computing, communications, and information technology industries) in every field: science, technology, public policy, and the arts, it often seems like the world is getting dumber. What if it really is?

That is the thesis explored by this insightful book, which is packed with enough “hate facts” to detonate the head of any bien pensant academic or politician. I define a “hate fact” as something which is indisputably true, well-documented by evidence in the literature, which has not been contradicted, but the citation of which is considered “hateful” and can unleash outrage mobs upon anyone so foolish as to utter the fact in public and be a career-limiting move for those employed in Social Justice Warrior-converged organisations. (An example of a hate fact, unrelated to the topic of this book, is the FBI violent crime statistics broken down by the race of the criminal and victim. Nobody disputes the accuracy of this information or the methodology by which it is collected, but woe betide anyone so foolish as to cite the data or draw the obvious conclusions from it.)

In April 2004 I made my own foray into the question of declining intelligence in “Global IQ: 1950–2050” in which I combined estimates of the mean IQ of countries with census data and forecasts of population growth to estimate global mean IQ for a century starting at 1950. Assuming the mean IQ of countries remains constant (which is optimistic, since part of the population growth in high IQ countries with low fertility rates is due to migration from countries with lower IQ), I found that global mean IQ, which was 91.64 for a population of 2.55 billion in 1950, declined to 89.20 for the 6.07 billion alive in 2000, and was expected to fall to 86.32 for the 9.06 billion population forecast for 2050. This is mostly due to the explosive population growth forecast for Sub-Saharan Africa, where many of the populations with low IQ reside.

This is a particularly dismaying prospect, because there is no evidence for sustained consensual self-government in nations with a mean IQ less than 90.

But while I was examining global trends assuming national IQ remains constant, in the present book the authors explore the provocative question of whether the population of today’s developed nations is becoming dumber due to the inexorable action of natural selection on whatever genes determine intelligence. The argument is relatively simple, but based upon a number of pillars, each of which is a “hate fact”, although non-controversial among those who study these matters in detail.

Fourmilab’s reviews are always insightful and worth reading in their entirety. And I don’t just say that because he has spoken well of one or two of my books.
