The Evolution of Human Psychology

The book is meant as a consciousness raising device to remind researchers and policy makers that much of what we think of as normal, quote, human psychology is actually the psychology of one particular population at one slice in time. It's an inclination of many researchers and probably people in general to assume that the psychology that they're recording among their population is readily generalizable to humans as a species. So even something is basic that psychologists thought was so fundamental and replicable turns out to just be something that's peculiar to the modern world.
