I’ve followed the works of E.O. Wilson for many years, starting with his book, Sociobiology: The New Synthesis (1975), which I read as a teenager. His recent death is both a great loss and an opportunity to remember his substantial contributions to evolutionary biology.

Gad Saad offers this excellent homage to E.O. Wilson’s work. One thing that stood out to me is Saad’s coinage of the term “human reticence effect.” Here is Saad’s explanation of this critically important term (and phenomenon):

The human reticence effect: It’s perfectly okay to apply evolutionary principles to explain one million nine hundred ninety-nine thousand, nine hundred ninety-nine species, but if you apply to study one species called humans, well then, you are Himmler and you’re a nazi. And so E.O. Wilson, in daring to apply incredibly rigorous and profound evolutionary principles to explain incredible animal behavior, including some very puzzling animal behavior, once he used that framework to apply it to human behavior, then he was a persona non grata which, of course, is exactly what you see 45 years later with evolutionary psychologists. If you apply a principle to study the evolution of mating behavior of the salamander then bruh, you’re a great scientist. If you apply the exact same mechanism the same methodology, the same epistemology, to study the evolution of human mating in humans, well then, come on bro that’s just faux science. It’s “nazi science” it’s “pseudoscience.” I have written about why people have these emotional and cognitive obstacles to accept the application of evolutionary principles to the study of human behavior in much of my scientific work.
