The raising of intelligence: A selected history of attempts to raise retarded intelligence. 1986. http://bookos.org/book/2175637/d00805 Very useful book. I had read about it in multiple sources. It is a history of attempts to cure the retarded and in general raise intelligence. The answer to the question "how much can we boost intelligence?" is still, as Jensen gave in 1969 (!) "not much".
