Two new pieces out in @smithsonianmag.bsky.social ! One on two dime-sized fossils that just rewrote our understanding of the vertebrate water-to-land transition (link below), and one on the most chemically primitive galaxy ever recorded (link in thread). www.smithsonianmag.com/science-natu...

A Vietnam Veteran Collected Fossils for 66 Years. One, Mislabeled 'Baby Lamprey,' Made Paleontologists Reconsider How Vertebrates Moved From Water to Land
The fossil turned out to be a hatchling of a crocodile-like creature, and it suggests, according to a new study, that early animals did not use metamorphosis to evolve to dwell on land

The combination of music and digital anonymity seems to make people feel like they can share memories with total strangers that they wouldn’t ever share in-person. Like the messages you find on bathroom stalls.

Oh, interesting idea. Wonder how that could be measured ... first (handwavey) thought is looking for some kind of correlation with measures of childhood mobility and birth rates in different places? (I can think of several confounds though)

Thanks! Yeah, it certainly poses new kinds of dangers. But so does playing in the street, climbing trees, etc. Question is how we can minimize those dangers without jeopardizing access to a broadly beneficial system. Very pro-regulation on certain kinds of algorithmic feeds, for example

Psilocybin mushrooms are found worldwide, yet I have long argued (based on direct evidence) that traditional use is confined to Mesoamerica. I was wrong! In a new paper led by @eselster.bsky.social, we document Indigenous psilocybin mushroom use—potentially very old—in highland southern Africa.

Genuinely groundbreaking work in psychedelic anthropology here! I understand that this is the first well-documented case of indigenous psilocybin use outside of the Americas. Fieldwork led by @eselster.bsky.social under @manvir.bsky.social also w/ Sandeep Nayak and myself

Above all else, though, it suggests cases of Indigenous psychedelic use, especially outside the Americas, may have been overlooked. We need people doing exploratory fieldwork to see what else is out there. If you’re interested in funding that work or doing it yourself -- get in touch!

This has many implications for the study of psychedelics moving forward. Stacking effects, the impact of psychedelics on dreams, microdosing . . . and much more.

People claim that psychedelics have been used by Indigenous groups around the world for millennia. But clear evidence of serotonergic psychedelic use has long been confined to the Americas. Until now. Here, we document clear evidence of Indigenous psilocybin use in Lesotho. 🍄 osf.io/preprints/so...

that was my take too - social media is bad for kids because it *enhances* the negative aspects of regular teenage life. before, if you didn't fit in, didn't have many friends, were bullied, etc, you could escape that after leaaving school. now you can't. also congruent with the evidence

Thanks Ben! Interesting thought — that view fits the rasa perspective well (in which art is supposed to induce the most pure form of a single emotion). But I wonder if intensity is necessarily also rich — i.e. a song mainly invokes sadness, but there’s fractal-like detail to that sadness?

Online Now: How experience shapes extraordinary beliefs
dlvr.it
How experience shapes extraordinary beliefs
The ubiquity of extraordinary beliefs across human societies, such as conspiracy theories, pseudoscience, and supernatural beliefs, is a long-standing puzzle in cognitive science. Prevailing accounts emphasize cognitive biases and social dynamics but often neglect a key factor: experience. We synthesize recent evidence and identify three pathways by which experience can shape these convictions: by filtering which beliefs feel perceptually plausible, by sparking new beliefs through anomalous and emotionally charged events, and by being engineered through immersive cultural technologies that simulate sensory evidence. These pathways function alongside cognitive biases and social processes, helping explain why certain extraordinary beliefs recur, why they often accompany vivid rituals, and why they can feel convincing despite evidence that challenges their veracity.

Why do people endorse seemingly extraordinary beliefs such as in pseudoscience & supernatural entities? Leading approaches stress cognitive biases (like agency detection) & social dynamics (like signaling). Eli Stark-Elster & I argue that experience matters too & put fwd a framework explaining how.
