Despite periods in history when evolutionary biology has been misused, there’s no denying that the study of biological human nature is intrinsic to the study of social and cultural human nature.

David Barash is an emeritus professor of psychology and evolutionary biology at the University of Washington, and a prolific author. His books like, Through a Glass Brightly: Using Science to See Our Species as We Really Are and Threats: Intimidation and Its Discontents explore many different corners of human nature and why it should be incorporated into the field of social sciences.

David and Greg discuss why there’s a resistance in the social sciences to study human nature, why it’s important to understand differences between the sexes, and why relying too much on deterrence could be a dangerous game.

Episode Quotes:

How social darwinism warped evolution

03:33: The unfortunate truth is that evolutionary biology in the past has been misused, especially shortly after Darwin—the whole time of social Darwinism. At which time, particularly right-wing zealots and supporters of imperialism and colonialism, were intrigued by the notion that somehow it was a misunderstanding of evolutionary biology, but they loved the idea that because of evolution, certain people notably, the "white races," were superior, that they were produced that way by natural forces, and hence it is appropriate for them to go ahead and conquer the world—conquer as many people as they can. Moreover, not just with regard to colonialism, but also with regard to the way things are at home. The wealthy are wealthy because they were biologically made superior, and we shouldn't argue with that. So there was that, and that's very much a misunderstanding of evolution and how it works.

Natural doesn't always mean good

12:44: The fact that something is natural doesn't mean that it's good, or that we have to succumb to it, or go along with it necessarily... [13;07] all sorts of feelings that one may have that may be "natural." That doesn't mean we have to go along with it. And by the same token, the differences that we observe in various human societies or between various individuals within society, the fact that it exists even, doesn't necessarily mean that's natural. It's a consequence of any number of things. And even if it was natural, it doesn't necessarily mean that it's good.

Why do male-female differences become problematic?

23:02: I think the reason male-female differences have been controversial has to do with something similar to why biophobia, in general, has existed, which is to say that recognition has been used in the past as a way of buttressing socially inappropriate distinctions. The notion that, well, men are more aggressive than women, men are more pushy than women, hence men are likely to become leaders, business leaders, political leaders, and that's all well and good; that's normal; it's natural; there we're back again to the naturalistic fallacy. And so, to some extent, that's, I think, a big part of the reason why male-female differences have become not quite toxic as an issue but really problematic.

Understanding infanticide

19:57: When we talk about such things as infanticide, I think we have a real obligation to make it clear: a.) that certainly, in the human case, it's extremely rare, and b.) the fact that it does happen in some cases, it's not uncommon among nonhuman animals. We need to make it very clear that that's not, in any way, a blueprint for how human beings ought to behave. There are lots of things in the natural world that are "natural." That's why we call it the natural world, but those aren't worth emulating. In fact, that is so important that we don't.
