Uh O. Charles Murray hath returned with more myopic race academic hot air?
Haven't read this book, but I know the author well. Have two of his past writings, incuding the important #BellCurve tome.
A GoodReads (VagaBond of Letters) user posted a rather excellent review, however:
As perfect and gentle a primer into the thorny jungle of the most important social and political facts facing the West as has yet been written.
Murray walks the reader through the evidence, compiling cases which are cumulatively irrefutable on the level of logic or empirical evidence to even the staunchest intersectionalist. The sources and methods are in the text and explained simply and in English instead of buried in endnotes, assuming prior knowledge of statistical experiment design.
Murray attempts to walk a middle path, which is his only weakness, expecting the left to repudiate its extremists (the 'moderating ideological triggers') without, in my opinion, understanding the shape of politics which perforce moves the Cathedral ever leftward, nor does he properly reckon the strength of the evolved group-identity modules explicated in social identity theory and genetic similarity theory: the atavistic 'jungle' is invading the egalitarian and individualist 'garden', to extend the author's metaphor, irreversibly.
He also does not correctly reckon the level of cognitive ability demanded in addressing emotional things in a rational manner because of his own life's experience as an academic and wonk. Only Europeans fail to take their own side, and any policy which is premised on the ability of the average man to inspect dispassionately that which induces the most heated passion is bound to fail.
