At the end of this book, it's still not entirely clear what McCaughey wants. 13 pages before the end, she does say "We must demand not only better science from the HBE theorists, but a better understanding of science in our culture at large." Well who doesn't agree with this?
She does make some compelling arguments. For one, the notion that men can embody some false narrative about their caveman tendencies (i.e. what she refers to as the Caveman Mystique) is no doubt a problem. Furthermore, that the science behind evolutionary psychology is often male-driven, tenuous, and worth critical examination is a point made by many many people. What, then, is the solution??? She offers very little insight, leaving her criticism without substance in an unfortunate number of cases.
Indeed, in many parts of this book, McCaughey commits the same crime of which she accuses HBE scientists and popularizers alike: she ignores variation. For one, I think that it is a stretch to claim that evolutionary biology has stepped in as the secular basis for morality in America. When less than half of Americans even believe in evolution or that humans descended from apes, this claim is farfetched to say the least. Secondly, I will not deny that the caveman mystique exists, but aside from frat boys and the frat-minded playboy subscribers, how extensive is this embodiment? Surely wide enough to merit a critique, but so pervasive that it even represents a significant chunk of men? Finally, where are the scientific dissenting voices arguing against the vapid claims of sex differences evolving in the pleistocene? She brings up a few, but dismisses them all. Some HBE researchers may have simple, evolutionary untenable and typological, views of the sexes, but McCaughey has a simple, typological view of HBE scientists! Many, many voices of scientists (many self-identifying as feminists) are shut out of her critique.
It's hard not to get the feeling that she is anti-science. Sure she defends science and HBE scientists, but it isn't clear how genuine this is. What kind of evidence would convince McCaughey of adaptive human behaviors, perhaps some of which are sex linked? I would have liked to see her confront this question, but have the feeling the answer would be "none whatsoever." Her alternative "hypothesis" that there may have been a bisexual free-for-all in human history, and that this narrative is as valid as the heteronormative one that she criticizes is one such example. Surely, diversity in sexuality is often ignored by scientists (but not always, either…there are plenty of books discussing such diversity), but to ignore all comparative research and ethnographic knowledge of human and animal behavior to suggest something as asinine as a bisexual orgy is groan-worthy and exactly the type of claim that makes her out to be against scientific inquiry into the evolution of human behaviors in the first place.
Maybe what we need is popularization of a detailed understanding of the naturalistic fallacy…science ought to be silent on morality. She gives plenty of examples of scientists overstepping their bounds, and I of course agree that science is created by individuals with biases, preconceptions, etc. That voices from science studies should be able to step up and critique the findings of science and the popularization of these findings is completely fair. But how? How to go about addressing popularization of scientific findings? How to go about popularizing the "homo textual" masculine identity she espouses in the last chapter? This book feels like a bread sandwich, with two slices of haughty critique and not a thing in the middle.
