Popular science and media are awash in sweeping claims concerning how some characteristic human behavior, feeling, or psychological disposition exists because it aided our evolutionary ancestors in survival and reproduction. These claims often arise from a discipline known as Evolutionary Psychology. Evolutionary Psychology claims to investigate the evolutionary underpinnings of human nature, to explain why we have the thoughts, feelings, impulses that are characteristic of human experience.
But when we compare these investigations with evolutionary research on other human traits, or on nonhumans, we see that Evolutionary Psychology is deeply out of touch with the basic theoretical and methodological precepts that form the basis of our knowledge of evolutionary history. By comparing research in Evolutionary Psychology with traditional forms of evolutionary research, we can appreciate the wide gap between what Evolutionary Psychology says about human nature, on the one hand, and what is traditionally required to support claims about evolutionary history, on the other.
The study of evolution is not the study of the design and purpose of nature-it is the study of how populations change over time and it requires the sort of investigation for which human subjects are generally ill suited. As Chris Haufe shows, Evolutionary Psychology has constructed a parallel scientific universe - cut off from genuine scientific knowledge of the evolutionary process - which seeks to actively promote a predetermined stance on human evolutionary history regardless of whether that stance is logically consistent with current scientific fact. Illusory Riches demonstrates that our scientific knowledge of the human past and of the evolutionary process permits a far greater range of human potentialities than one might suspect from the claims of Evolutionary Psychology.
