'For decades, Ken Richardson has been a leading voice within the critical approaches to intelligence in psychology. He patiently and determinedly interrogated the often taken for granted assumptions – and myths – about the meaning of intelligence, about how it can be measured and tested, about its heritability or its applicability as a measure of intellectual ability in the school or the workplace. Understanding Intelligence provides a thoroughly researched and persuasively argued up-to-date overview of this important work. It is sure to become an indispensable resource for both academics and practitioners, and indeed for anyone interested in one of psychology's most controversial, and flawed, concepts.'
