  1. Can human intelligence be measured? Here the world-famous Harvard scientist Stephen Jay Gould makes a fascinating investigation.
  2. From nineteenth-century craniometry (literally, the measurement of skulls) to today’s vastly sophisticated methods of IQ1 testing, he traces the history of scientists’ attempts to assess human intelligence. Along the way, he tackles the fundamental problems: the very idea of measurement seems reductive, suggesting that biology is destiny; moreover, as he vividly demonstrates, scientists’ theories have too often been dangerous reflections of their own personal motives and racial / class / sexual prejudices.
  3. Elegantly written and tightly argued, this book exposes the fatal flaws in intelligence testing - a manner of measuring that has become one of the most potent ideas in modern life - and reaffirms the richness and variety of human potential.
  4. ‘This is a marvellous book, and it is marvellous in lots of different ways. The history of these attempts to measure the intellectual and moral worth of individuals turns out to be a detective story to rival most of Agatha Christie’
