Panicked headlines about a “fertility crisis” are not being driven by experts who understand fertility trends 👇 Next time you see such a headline, worth thinking about whose interests “demographic collapse” narratives serve

It is not always this deranged. There are competent researchers in the field. Unfortunately it has always had a deranged wing which the discipline has never properly tackled

I was wondering if giant tortoises are distinct enough from one another for it to be easy to count 180,000 of them…

My theory about RFK Jr. is that this is individualism taken to its extreme: don't regulate food, don't mandate vaccines. If you get sick, you should've done your own research. Your health is your own responsibility, even when corps. are allowed to put you at risk. The privatization of public health.

I’ve seen a few folks comment that “Guinea-Bissau is a low income country and cannot afford the hep B vaccine birth dose, so why is this study unethical?” It’s a good question. Let me have a go at answering it. In a nutshell, researchers cannot ethically exploit poverty & scarcity to do a trial

"Whatever we call it, Bashford says, the eugenicists of a century ago “would undoubtedly be delighted at contemporary possibilities for reproductive selections.”"
Good to see @danfalk.bsky.social digging into the ugly return of eugenic thinking.

i’m so glad that @philipcball.bsky.social wrote about Conrad Waddington. Like Lamarck, he has been accused of believing evolution is purposive. Lately, ppl are finding that there can be direction in evolution w/o anything supernatural about it. Good to see Wad getting better press

Going to be quite preoccupied today thinking about how you count giant tortoises: “Aldabra’s giant tortoise monitoring programme is one of the longest running in the region, but the atoll’s dense vegetation makes counting tortoises genuinely difficult in places”

* there is no bright side here. The lack of concern for the job losses - which will not just be among the laptop classes, and shrinking of access to education - which will hit the least privileged hardest, resulting from a *Labour* govt's policies is dispiriting, to use the mildest possible term

@rebeccasear.bsky.socialOct 10, 2026, 9:21 AM

Looking on the bright side, at least there'll be no higher education sector left to destroy when a far-right party finally takes power in the UK*

This is a very disturbing read by Philip Moriarty about the corporate consultants at University of Nottingham, whose "bloodless prime-LLM-grade corporate boilerplate" called Future Nottingham 2 is guiding decision-making - cuts, cuts and more cuts.

New working paper: the Norwegian wealth tax was a huge success. The "exodus" of wealthy people never happened (less than 100 individuals left). Tax revenue increased by 71.5%. No changes in business activity or investment.

Taxing Entrepreneurial Wealth: Evidence from
Norway, 2021-2025
Marius A. K. Ring
WORKING PAPER 35854|
DOl 10.3386/w35854
ISSUE DATE October 2026
Whether imposing higher taxes on business owners adversely affects business activity by constraining investment and inducing capitalist flight is a central question in the ongoing debate on how to tax the ultra wealthy. To shed new light, I exploit a series of related Norwegian reforms during 2021-2024 that increased dividend tax rates, removed migration-related capital gains tax loopholes, and nearly doubled the effective marginal tax rate on business wealth. These reforms spurred international debate and, allegedly, an "exodus" of Norwegian billionaires (Financial Times,
2023). While I document clear effects on migration, these responses are concentrated among the top 0.1% of the wealth distribution and mostly confined to 2022 and 2023. My results indicate that at most 100 individuals left due to the reforms. I find no evidence of significant outmigration or reduced inflows of startup founders or inventors. I estimate that absent any outmigration, wealth tax revenues would have increased by 75% from 2021 to 2024. Reform-driven outmigration lowers the revenue gain to 71.5%. My findings further show that outmigrating owners' firms remain economically active and do not reduce investment. In a broader set of analyses, I examine whether business outcomes are affected, regardless of whether owners outmigrate, since firms may reduce investment both due to liquidity constraints or distortions to owners' savings decisions. I compare firms owned by Norwegian individuals subject to the wealth tax with firms owned by foreigners and other tax-exempt entities. By merging historical ownership data from Orbis with the Norwegian shareholder register, I perform these analyses on both Norwegian and foreign-domiciled firms.
Across settings, I find no evidence that Norwegian-owned firms pay out more dividends or invest less after the reforms,…

Very nice paper by @lljschoenmakers.bsky.social on how to interpret debates over adaptationism. He argues that the sides of the debate are divided by different commitments about what constitutes genuine scientific understanding.

With more and more websites going down, whether overwhelmed by bot traffic or starved of ad revenue, it is time for scholarly referencing guidelines for citing a website to include an archived version, just as Wikipedia has long recommended en.wikipedia.org/wiki/Wikiped... #metascience

"the meme is the 19th century reformatted. Where race science once leaned on calipers & cranial photographs to make hierarchy appear fact, the meme keeps the visual grammar & throws away the instruments...this is Scientific Racism 2.0: same essentialist conclusions, recoded for an attention economy"
