one reset I'd personally appreciate: behind the insistence that we must offer the electorate a little bigotry is the idea that commoners are more bigoted than the richer and more educated, who can be appealed to with high minded policy. but then you Ctrl+F "phrenology" in the Epstein files
What strikes me is that 'the volk' have incredibly incoherent and everywhere ideas, but the people who claim to speak for them in the press are like clerics who think there are two poles for all politics and everything must fit between them. These poles are like, eight inches apart

Hello Bluesky!
Does Nₑ really explain mutation rate (μ) or genome size (GS) in vertebrates?
We find the apparent Nₑ–μ link in Bergeron et al. (2023) is a “back-door” path via generation time, and GS is decoupled from both Nₑ and life-history traits.

Weaponised correlation is causation, as usual
This really is indistinguishable from self-satire from Thomas Chatterton Williams: The left should stop criticizing slavery because its causing the right to excuse slavery.

Yes it’s Valentine’s Day. But it’s also the chosen birthday of Frederick Douglass who was born in 1818 on a plantation in Talbot County, Maryland. He escaped from slavery & rose to become the most eloquent and forceful voice for the abolition of slavery & for Black voting rights in the U.S.

🧪🧬 Today is the observation of Frederick Douglass' chosen birthday. I say "chosen" because he was robbed of the knowledge of the exact date of his birth by those who enslaved him. Today is a good day to read his 1854 commencement address to Western Reserve College.1/2

This is a very good and accessible article about why the blueprint metaphor for the genome is inapt.
The genome isn't a blueprint. But what is it?
I originally imagined this as a reported feature on metaphors of the genome, but it ended up being an essay.
And at the end I share the metaphor I personally ended up landing on. If you want to tell me why it is wrong, you'll need to read the story ;)🧪

Social media is awash with videos of men filming themselves approaching women in public spaces and attempting to flirt. In many cases, the videos are filmed and uploaded without the women’s consent. https://cnn.it/4qtIsvB

I agree. They think they’re great because they showed up. By their own admission, they had nothing to do with their own success.
…which just goes to show how stupid & undeserving they are…
Evil men like Epstein are, in the simplest form, obsessed with eugenics because they believe that their ill-gotten gains are the product of some innate superiority.
