World Athletics is supporting female sport: It sounds so simple that you wonder if there’s something you’ve misunderstood. In order to “doggedly protect the female category”, World Athletics President Sebastian Coe has announced that his organisation will become the first to introduce cheek swabs or dry blood tests to verify an athlete’s biological sex. These are […]

This paper examines the effects of the Big Five personality traits on labor market outcomes and gender wage gaps using a job search and bargaining model with parameters that vary at the individual level. The analysis, based on German panel data, reveals that both cognitive and noncognitive traits significantly influence wages and employment outcomes. Higher […]

Jerry Coyne has found a wonderful new research paper. The abstract is: This article offers a queer lesbian feminist analysis attuned to lesbian-queer-trans-canine relationalities. Specifically, the article places queer and lesbian ecofeminism in conversation with Donna Haraway’s work on the cyborg and companion species to theorize the interconnected queer becomings of people, nature, animals, and […]

This announcement came from our Provost’s office, but apparently hasn’t been sent to all parts of the University. Nevertheless, it surely applies to all job ads for the University of Chicago. What it shows is that the University has updated its Equal Employment Opportunity statement, a statement that must be included in all ads for […]

It’s not only unconscionable for “progressive” Democrats to cheer on trans-identified males (“transwomen”) who compete in women’s sports, but that behavior certainly hurt the Democrats, especially because most Americans, including Democrats, think that this kind of participation should be forbidden: A recent New York Times/Ipsos survey found the vast majority of Americans, including a majority…

It’s still International Women’s Day in some parts of the world. There are still people who believe their feelings about their gender can trump biological facts. There are still people who risk their jobs if they question gender ideology. But there are also people fighting back, among them is Sall Grover: The founder of a […]

I’ve written sentences like this many times: “While biological sex is a binary, gender in humans forms more of a spectrum.” But I was never really sure what “gender” meant. I know that it’s generally synonymous with “sex”, but that is clearly not what I meant when I spoke as I did above. What did […]

I guess the number of papers and articles people send me about the definition of sex is one sign that it remains an important issue for the populace. Indeed, I think that in future decades people will see the kerfuffle about a simple and widely accepted definition (the gametic one) as a tempest in a […]

First, next Monday, Mar 3 at 12:30 Chicago time (1:30 Eastern time), I am having a 1-1½-hour discussion with DIAGdemocrats (“DIAG” stands for Democrats with an Informed Approach to Gender.

Jon Klick finds that when courts in CA surprisingly invalidated a set of DEI laws, the market value of firms subject to those laws increased: California mandated that firms headquartered in the state include women (SB 826) and underrepresented minorities (AB 979) on their corporate boards. These laws, passed in 2018 and 2020 respectively, were […]

This article was mentioned in a comment by reader Ted Gold, but I thought I would highlight it just to show that when the rubber meets the road, people recognize that, yes, there are just two sexes. This is from the NYT on Feb. 25th. Click headline to read, or find the article archived here. […]
