I find this book much too superficial and outright intellectually dishonest on a number of points. While the book is informative on the historical context of some notions of race, his attacks on many studies that he thinks imply inferiority of races contain obvious distortions.
For instance, in the beginning of chapter 5 his lampoons a study that reveal statistical observations showing that a certain collection of countries have a significantly higher rate of airline crashes than certain 1st world countries and attributes this to a relative lack of "individualism" in challenging authority ( a fear of not deferring to authority is a well known factor in some airline crashes). Malik notes that these more airline accident prone nations are non-white and so accuses this study of essentially hiding a racial prejudice under a presumption of cultural difference:
`By transposing racial difference to cultural difference the notions of "inferiority" and "superiority" had become acceptable, even scientific." `
This is just jumping to preferred conclusions; the study was rightly noting statistical differences and associating them with a certain cultural traits that could be quite valid. Malik is too politically correct to tolerate the possibility of such differences.
Malik, in my opinion, is at his most intellectually dishonest (but politically correct) in his simplistic dismissal of the famous "Bell Curve" book as a "hodgepodge of everyday prejudices" and flawed methodology stemming from "the treatment of race as a biological entity" and "failing to understand intelligence as a social product and conflating correlation and causation." He simply assumes that Murray and Herrnstein were complete idiots. Their treatment of race did not necessarily assume a biological basis, in fact, one can just talk about human groups specifically and measurable group differences (and avoid the word "race"), which have averages (like IQ averages). And there are many psychologists who would take issue with the idea of "intelligence" as just a social product: the Bell Curve book talked of "cognitive ability" or IQ to avoid this loaded word. Furthermore, Murray and Herrnstein go to some pains to explain that they are not conflating correlation and causation. But it seems to be PC sufficient to discredit this book with superficial blather.
This is just a another safe & shallow book on race that the author knows will easily get applause.
