Cat is a researcher who focuses on the evolution of narrative and cognition. Her essays and poems have appeared in Scientific American, Mind, Science Magazine, and other publications. Her fascinating new book is Eve: How the Female Body Drove 200 Million Years of Human Evolution, and I highly recommend it.

For two clips of our convo — on the combat that occurs within a pregnant woman between mother and child, and the magic of nipples while breastfeeding — pop over to our YouTube page.

On that “20 percent of humans are homosexual” question, which I challenged directly on the podcast, it turns out Bohannon made a mistake which she says she will correct in future editions. As often happens, she conflated the “LGBTQ+” category with homosexuality, and relied on a quirky outlier study rather than the more reliable and standard measurements from places like the Williams Institute or Gallup. Williams says 1.7 percent of Americans are homosexual, i.e. gay or lesbian. Gallup says it’s 2.4 percent. The trouble, of course, with the LGBTQIA+ category is that almost 60 percent are bisexual, and the “Queer” category can include heterosexuals as well. As a way of polling actual, same-sex attracted gays and lesbians, it’s useless. And designed to be useless.

Note too Gallup’s percentage of “LGBTQIA+” people who define themselves as “queer”. It’s 1.8 percent of us. And yet that word, which is offensive and triggering to many, and adopted by the tiniest fraction of actual homosexuals, is now regarded by the mainstream media as the right way to describe all of us. In the podcast, you can see that Cat simply assumes that “queer” is now used universally — because the activists and academics who form her environment have co-opted it. She readily sees how that could be the case, when we discussed it. I wish the MSM would do the same: stop defining all gays the way only 1.8 percent of the “LGBTQ+” “community” do. Of course they won’t. They’re far more interested in being woke than telling the truth.
