Philogyny, fondness, love, or admiration towards women and gynolatry, worship of women are much more common than misogyny, but spoken about much more rarely.

The factoid that '50% of marriages end in divorce' was kinda true decades ago.
But the divorce rate peaked in 1980.
Now, less than 40% of all marriages since 2000 end in divorce.
For college graduates, it's under 30%.
For college graduates who get married after age 25, and who don't have any kids before marriage, it's under 20%.
Anybody promoting the outdated, deceptive 50% rate has some kind of anti-marriage or anti-natalist agenda.
It scares young people away from getting married and having kids. That is their goal.

Buffalo Hump - a War Chief of the Penateka band "had one of those Comanche names- there were a large number of them- that the prudish whites could not quite bring themselves to translate. His Nermernuh name, properly transliterated was Po-cha-na-quar-hip, which meant 'erection that won't go down'" - Gwynne

Belgium is preparing a criminal case against philosopher @nathancofnas that could result in up to 3 years of jail time.
Why jail a philosopher? Because Cofnas has argued that some race differences in psychological traits might be due to genetic differences. And this allegedly violates a new law that Belgium passed a month ago against 'dissemination of racial ideas' and 'incitement to discrimination or racial hatred'.
Here @Rosalind_Arden_ breaks down this strange story of censorship, retaliation, and institutional bullying of scholars who address taboo topics.

Every time I hear about "food insecure" Americans I'm like "does that just mean they are afraid the food doesn't like them back?"

Here is what all fields look like for PhD production based on Survey of Earned Doctorates.
Since 2015 (shaded part), humanities and arts are down, but so are business, education, social sciences (non-psych).
On the whole, PhD production continues to rise.
The number of people writing dissertations in the humanities has collapses, now the same thing is happening in the social sciences.
I'd wager that we will see a similar trend in psychology and other fields before long. Cuts in funding, the tight academic job market, and AI are rapidly changing the university and cratering graduate programs.

I get older every day at the rate of one day per day. Will there one day be a lady prettier than me? There are already thousands!
There’s no one else my husband could “trade in” for who is the mother of his children, who has held hands at funerals, who has our long history.
The alphabet song on our reading app is supposed to teach phonics, but my girls are far more interested in discussing whether the dancing letters are boys or girls based on their eyelashes.

We've been evolving faster than ever:
New analysis of ancient DNA is overturning the old assumption that 'human mental traits haven't evolved in the last 40,000 years'.
This recent paper (April, 2026) analyzed genetic data from over 10,000+ ancient people from West Eurasia (Europe, Middle East, West Asia) over the last 10,000+ years, compared to 6,000+ modern people. They analyzed strength of selection for or against 9.7 million genetic variants.
They found strong positive selection for intelligence, and strong negative selection against several mental disorders -- all since the development of agriculture & more complex societies.
New from David's Reich's lab: "In the past ten millennia [in Europe], we find that many hundreds of alleles have been affected by strong directional selection," including those influencing human intelligence.

People ask me what I think of "The Mating Mind" and I say "it's so good it's why my children exist".

Noah is joined by @gmiller to discuss the evolution of intelligence and why AI is a threat to "everything we know and love". aporiamagazine.com/p/podcast…
Herasight is pioneering a new kind of embryo screening.
NeuroRisk screens for rare inherited damaging variants so couples can reduce the risk of having a child with severe autism or intellectual disability.
Declining interest in IVF and egg freezing in this survey may largely reflect declining interest in having children at all. Respondents are also far less interested in adoption.
Unfortunately, the wording of the question about wanting children changed. In 2017, 80% of singles under 40 said it was important to find a partner who wanted children; by 2021, that was 61%. In 2026, just 38% of singles aged 18–49 say they want children.
Interest in IVF + egg freezing is tanking: "“From 2017 to this year, the share of respondents who said they would be willing to consider IVF fell by more than half, from 44 to 18 percent. Openness to egg freezing dropped from 33 to 17 percent.” 44 👉 18!
