The book is impressive and readable, but Robson trips up on one of his own snares: the straw man. Attacking a narrow, mid-20th-century, IQ-based understanding of intelligence is not difficult. And for all that the book feels exciting, with all that psychological evidence and all those technical terms, the pitfalls it identifies and the solutions it offers will feel familiar to anyone with a classical education. Curiosity, intellectual humility, reflectiveness, autonomy? It sounds like good old-fashioned scepticism. And who did not know that the cleverest person can be a fool?
