We are becoming less intelligent. This is the shocking yet fascinating message of At Our Wits' End. The authors take us on a journey through the growing body of evidence that we are significantly less intelligent now than we were a hundred years ago. The research proving this is, at once, profoundly thought-provoking, highly controversial, and it’s currently only read by academics. But the authors are passionate that it cannot remain ensconced in the ivory tower any longer. With At Our Wits’ End, they present the first ever popular scientific book on this crucially important issue. They prove that intelligence ― which is strongly genetic ― was increasing up until the breakthrough of the Industrial Revolution, because we were subject to the rigors of Darwinian Selection, meaning that lots of surviving children was the preserve of the cleverest. But since then, they show, intelligence has gone into rapid decline, because large families are increasingly the preserve of the least intelligent. The book explores how this change has occurred and, crucially, what its consequences will be for the future. Can we find a way of reversing the decline of our IQ? Or will we witness the collapse of civilization and the rise of a new Dark Age?
What Causes the Anti-Flynn Effect? A Data Synthesis and Analysis of Predictors

Anti-Flynn effects (i.e., secular declines in IQ) have been noted in a few countries. Much speculation exists about the causes of these trends; however, little progress has been made toward comprehensively testing these. A synthetic literature search yielded a total of 66 observations of secular IQ decline from 13 countries, with a combined sample size of 302,234 and study midyears spanning 87 years, from 1920.5 to 2007.5. Multilevel modeling (MLM) was used to examine the effect of study midyear, and (after controlling for this and other factors) hierarchical general linear modeling (GLM) was used to examine the following sequence of predictors: domain “g-ness” (a rankorder measure of g saturation) Index of Biological State (IBS; a measure of relaxed/ reversed selection operating on g), per capita immigration, and the 2-way interactions IBS g-ness and Immigration g-ness. The MLM revealed that the anti-Flynn effect has strengthened in more recent years. Net of this, the GLM found that g-ness was a positive predictor; that is, less aggregately g-loaded measures exhibited bigger IQ declines; IBS was not a significant predictor; however immigration predicted the decline, indicating that high levels of immigration promote the anti-Flynn effect. Among the interactions there was a negative effect of the Immigration g-ness interaction, indicating that immigration promotes IQ decline the most when the measure is higher in g-ness. The model accounted for 37.1% of the variance among the observations.
