The book is a sociologist trying to interpret the history of behavior genetics into sociology theories. I didn’t pay much attention to their theorizing, being familiar with that kind of nonsense or useless theory. It generally employs the kind of kind of terminology that sociologists are known for: reductionism here, genetic determinism there, racism, eugenics, Nazi, blahblah. It is somewhat dated despite just being released. This is the nature of legacy publishers, since it takes so long go get thru their machinery. It spends a lot of time talking about how the molecular (GWA) studies did not fulfill the dreams of behavior geneticists. This is however semi-moot now due to the fact that recent studies have replicated findings of g-genes and used GCTA to estimate heritability values that make extreme environmentalism impossible to hold onto.
It, however, did contain a lot of interesting quotes from unnamed persons, and various other stuff. It is recommended for those who have an interest in the history of behavior genetics and the race and IQ debate. I cannot give it 4 or 5 stars despite it being interesting due to the aforementioned problems.
