= Hans J. Eysenck = H.J. Eysenck Hans Jürgen Eysenck (/ˈaɪzɛŋk/; 4 March 1916 – 4 September 1997) was a psychologist born in Germany, who spent his professional career in Great Britain. He is best remembered for his work on intelligence and personality, though he worked in a wide range of areas.

A book that deals with inequality in a general way without going in to specifics. I guess in order to claim the moral high ground in a PC-tyranny. This in my opinion is its strength in that it becomes more abstract and its weakness as it does not tell the whole story.
One downside to this book is that it relies to some extent on the work of Cyril Burt who had not been caught faking his research yet at the time of writing this book. This does not make any difference to the actual facts because countless similar studies from a host of other researchers have reproduced the results so the facts stand, it just looks bad.
I do think Eysenk are overestimating (or oversimplifying) the concept of regression to the mean some what. It absolutely does insure upwards and downwards mobility with regard to intelligence just not to the extent that Eysenk seems to imply. In my opinion Arthur Jensens more modest assurances in his book “Straight talk on mental tests” are much closer to the mark.
