The relationship between testosterone and grip strength, an index of physical formidability, in a representative sample of US adult men (point sizes are survey weights). 🧪

A scatterplot of combined grip strength (y-axis) vs. serum testosterone (x-axis) in 3498 US adult men (18-60) from NHANES 2011 - 2014. A polynomial smooth regression line is completely flat. Combined grip strength is the sum of grip strength in both hands. Point sizes are survey weights.

Some entertaining zingers from the judges on their decision upholding academic freedom. Worth a few minutes of your time 🧪 My favorite: "The ideas Florida targets may well be noxious. Or maybe not. Either way, in this context the First Amendment trusts students to figure it out for themselves"

BREAKING: Eleventh Circuit, on a 2-1 vote, upholds injunction blocking Florida from enforcing its 2022 Stop WOKE Act in the university context. The majority opinion is from Judge Britt Grant, a Trump appointee: storage.courtlistener.com/recap/gov.us...

Before GRANT, LAGOA, and WILSON, Circuit Judges. GRANT, Circuit Judge: "Congress shall make no law ... abridging the freedom of speech." U.S. Const. amend I. The First Amendment, incorporated against the States in 1868, is this country's written commitment to the idea that freedom of speech is essential to freedom of thought, and that both are essential to maintaining our liberty. The Supreme Court has long been clear that teaching and scholarship are due some measure of protection under the Amendment. But how much? And in what contexts? That Court has not had to say, but this one is now put to the test. The State of Florida legislated a broad set of speech restrictions banning certain viewpoints relating to race, color, sex, and national origin in various settings. The provision at issue here bars Florida's educators from promoting or endorsing those distavored ideas when instructing students. Its prohibition applies not only in primary and secondary education, where states traditionally exercise a great deal of control, but also in public colleges and universities, where the state government's role has been far more limited. When several groups of professors challenged Florida's new restrictions, the State cast about for an existing case or doctrine that could support its speech ban in the university setting. Finding none, it tried to marry public-employee speech cases with government speech doctrine, resulting in a new rule: if the

I need #rstats #stats advice. 59 kids in 2 ethnic groups were observed for 2 hours each, & the # of times they learned something from parents (vertical), other adults (oblique) or peers (horizontal) was recorded. Each row is one child. Q: How to test if ethnicity is associated w/ learning mode?

I've updated this plot of data from @thefireorg.bsky.social on campus deplatformings and attacks on scholars (1) with complete data for 2025, (2) by changing the incidents plots to cumulative sums of incidents by year, and (3) adding the topics involved 🧪 #AcademicSky

top left: most deplatforming by students, administrators and activists. top right: increase in campus deplatforming from 1998-2025, led by attacks from the right. bottom left: most attacks on scholars by students, administrators and activists. bottom right: steep increase in attacks on scholars starting around the start of the Trump era, with a huge recent spike of attacks from the right. Very bottom: dot chart of topics involved in each incident. The top 3 are race, political views, and gender, with more of each from the right than the left

My plot of @thefireorg.bsky.social data. Early on, campus deplatforming was more from the right, then more from the left, & now equalizing at a high level. Attacks on scholars were rare until 10 years ago, then increased by both sides, w/ a recent steep drop of attacks from the left 🧪 #AcademicSky

The grandmother hypothesis is seen as the "feminist" version of human evolution, but if so it's a dark version. At its heart is the recognition that despite higher male mortality, menopause sharply restricted the pool of fertile women relative to fertile men👇 intensifying male-male competition 🧪🧵1/4

A plot showing that despite higher male mortality, the ratio of fertile men (18-60) to fertile women (18-40) is almost always greater than 1, and was probably around 1.4 to 1.5 fertile man per fertile women for life expectancies typical of hunter-gatherers.

The joint @ces2026.bsky.social / #HBES2026 is a wrap. Local organizers @zhgarfield.com, @edseabright.bsky.social, @sarahalami.bsky.social, & @matcharbonneau.bsky.social & their amazing support team pulled off TWO back-to-back conferences. The vibe, food, high-tech venue & talks were fantastic!

1. Steve Jobs realized that "People hate their phones". Apple invented a better one, made bank, & changed the world. Academics hate their scientific publishers. Bluesky invented a better publishing platform, & could bank some of the ~$20B/year sci pub revenue, changing science 🧪 @toni.bsky.team 🧵

1. In this paper, we included this word cloud of the top 200 words in the volume Man the Hunter. A reader wondered how could the top 200 words in a book with the title "Man the Hunter" include "woman" but not "man"? Doh! 🧪 #rstats #BioAnth #AcademicSky 🧵

1. Does research by @caraocobock.bsky.social & others, widely reported in SciAm & elsewhere, finally dispel hunter-gatherer myths that have persisted since the 60's? In a preprint led by @vivek123.bsky.social The Meanings & Dividends of Man the Hunter: osf.io/preprints/os... we respond 🧵🧪

A unique prediction of an evolutionary approach is that some puzzling aspects of psych & health are best explained by mismatches of modern environments to the ancestral one. Yet the utility of the mismatch concept has been questioned by @joshtybur.bsky.social & @danielnettle.bsky.social 🧪 #BioAnth 🧵

Wish there was a better academic publishing system? Bluesky and its underlying ATProto technology, along with services like @chive.pub and the broader @atproto.science ecosystem, could do the job. #AcademicSky 🧪 leaflet.pub/2f431faf-c12...

Each academic paper should have its own Bluesky account
