'The human mind is an elaborate product of natural selection. Optimally Irrational is very welcome in bringing into focus the evolutionary underpinnings of human cognition as applied to economic decisions. Behavioural economics has often taken psychological mechanisms as arbitrary, without regard to the evolutionary design problems that created them. Such an atheoretical approach is questionable in view of the replication crisis in psychology. Page's deeper examination of behavioural economics is thoughtful and wide ranging. I learned much from this insightful and engaging book.' David Hirshleifer, Professor of Finance, University of California at Irvine
