MAHA just announced that states will be able to prohibit people from purchasing junk food with SNAP.

They claim this will make people healthier. That it’ll force them to make better choices.

It won’t.

Why? They aren’t addressing the privilege involved with healthy eating 🧡

Tom Lehrer, Influential Satirist Whose Topical Songs Poked and Prodded America in the ’50s and ’60s, Dies at 97 Tom Lehrer, an influential musical satirist who came to fame with songs addressing topical events in the '50s and '60s, has died at age 97.

We will all go together when we go,
All suffused with an incandescent glow.
No one will have the endurance
To collect on his insurance,
Lloyd's of London will be loaded when they go.

Finding Peter Putnam The forgotten janitor who discovered the logic of the mind

If you haven’t yet read Amanda Gefter’s incredible story about the forgotten philosopher Peter Putnam, I can’t recommend it enough.

This man worked as a janitor - but previously came up with a groundbreaking theory of the human mind.

I was excited to write a piece for the UNESCO Courier, @unesco.org's official magazine, about the current state of archaeology.

TL:DR Thanks to new techniques and finds, many "classic" narratives of human (pre)history are being rethought.

Geologist Harold Berghuis collected more than 6,300 animal fossils from an artificial island in the Madura Strait. The fossils, including some shown here from elephant-like and hippopotamus-like creatures, are helping to re-create what a landscape now drowned by the sea once looked like.

I agree with all of that. I think it’s also a question of industrial pressures. Many journalists are having to churn out 4 or more stories per day (your story was by a senior BBC correspondent, so probably not quite that dire). That means no time to think or dig, and causes all sorts of problems.

It’s always a balancing act. Of course you want to be accurate, especially when the terminology has historical sensitivities. But at the same time, if you don’t make it crystal clear to readers what you’re on about, they won’t read it at all - and then you’ve *definitely* failed to communicate πŸ˜†
