John Walker writes<\/a>: That is the thesis explored by this insightful book, which is packed with enough \u201chate facts\u201d to detonate the head of any bien pensant academic or politician. I define a \u201chate fact\u201d 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 \u201chateful\u201d 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.)<\/p>\n

In April 2004 I made my own foray into the question of declining intelligence in \u201cGlobal IQ: 1950\u20132050\u201d 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
