While thinking about about objections to the sex binary—usually discussed in humans but sometimes in other species—they all seem to come down to a single assertion: “Sex is complicated in both development and expression, involving chromosomes, behavior, hormones, genitals and even psychology. Therefore there are more than two sexes.” One example of this is from […]

And so we come to the last sex post of the day—about a new piece by Richard Dawkins on his Substack site, The Poetry of Reality. Richard points to what he sees as arrant hypocrisy in the statement on biological sex by the Presidents of the SSN, ASN, and SSB. As I mentioned in my […]

There will be a few posts on the definition of sex today, as everything “dropped”—as the kids say—at the same time. First, on January 20, the Trump administration issued an executive order, “Defending women from gender ideology extremism and restoring biological truth to the federal government”—an attempt to efface gender ideology from the government and […]

Six days ago I posted a group letter to the Presidents of three ecology/evolution/systematics societies who had issued a joint statement that many of us found deeply misguided. As I wrote at the time: The Presidents of three organismal-biology societies, the Society for the Study of Evolution (SSE), the American Society of Naturalists (ASN) and […]

My friend Phil Ward at UC Davis found this reference and called it to my attention. It’s from the Philosophical Transactions of the Royal Society (B), and access is free (click on title below). The pdf with the numbered references is here. The paper is about how the evolution of two different types of gametes […]

As I reported recently, the Presidents of three organismal-biology societies, the Society for the Study of Evolution (SSE), the American Society of Naturalists (ASN) and the Society of Systematic Biologists (SSB) sent a declaration addressed to President Trump and all the members of Congress. Implicitly claiming that its sentiments were endorsed by the 3500 members […]

Here’s a quick update on my critique of a letter issued by three organismal-biology-society Presidents claiming that sex isn’t binary—not in humans and, indeed, not in any species. The signers were the Presidents of the Society for the Study of Evolution (SSE), the American Society of Naturalists (ASN), and the Society of Systematic Biologists (SSB), […]

Does the Gender Wage Gap Actually Reflect Taste Discrimination Against Women?

One explanation of the gender wage gap is taste discrimination, as in Becker (1957). We test for taste discrimination by constructing a novel measure of misogyny using Google Trends data on searches that include derogatory terms for women. We find—surprisingly, in our view—that misogyny is an economically meaningful and statistically significant predictor of the wage […]

I wish I had a happier post for number 30,000, but you’re stuck with this one. However, it’s in line with the kind of stuff I’ve been writing about for a while, so it’s appropriate. Today we must deal with a letter from the Presidents of three organismal evolution and ecology societies (The Society for […]

(This is my 29,994th post, so we’ll reach 30,000 by the end of the weekend. I don’t know what to think about that!) I think we all know now that most Americans, and a majority of individuals in both Democratic and Republican parties, oppose the participation of trans-identified males in women’s sports, presumably on the […]

It’s well-known that when a couple has a child, the average woman experiences a “child penalty” in labor market outcomes, while outcomes for the man are largely unchanged. For a discussion of this pattern using US data, here’s an article by Jane Waldfogel from back in 1998 in the Journal of Economic Perspectives. As that…

Last night, I discussed a new executive order signed by President Donald Trump that included an extension of his earlier move against “diversity, equity, and inclusion” (DEI) policies to the area of higher education. The order makes direct reference to the decision of the United States Supreme Court in Students for Fair Admissions v. Harvard, […]
