It’s been described to me as ‘write something, so you have something to change’
It’s true. If I had learned this… I dunno, 35 years ago?… I’d have had a very different writing career.

After all these reports of authors adding language instructions for LLM reviews in their papers I wanted to check this myself and I downloaded the .tex source from one of these papers.
Here is an example.

Really proud of this new work out @psychscience.bsky.social. Led by the amazing but bluesky-less Amanda Geiser and with @deborahsmall.bsky.social.
We show that when comparing moral wrongs, people are (much) more willing to “scale up” than to “scale down” condemnation and punishment…

I really liked this idea of using a histogram as a legend in a choropleth map (since land isn't unemployed; people are), so I made a little guide to doing it with #rstats, {ggplot2}, and {patchwork}

A good general epistemic rule of thumb: If you have spent a few hours or weeks studying an area large numbers of smart, educated people have worked in for decades, and you believe you have discoverer an earthshattering truth they all missed, your default should be to regard this as VERY unlikely.
Elon Musk is an idiot on an almost inconceivable scale. He had his high-school toadies pull a random list from a database he doesn’t understand, and on that basis alone decided that 60 MILLION SOCIAL SECURITY ENROLLEES, out of 72 million total, are fraudulent. 83% fraudulent!

As someone trained as a trade economist, it is my duty to share the 1929-1933 Kindleberger Spiral, showing the month-month decline in global trade due to the combined factors of the (global) Great Depression and retaliatory tariffs. Smooth Hawley is implemented mid-June 1930.

One of the best things you can do right now is read books. Buy them. Borrow them from the library. Gift them.
Read history. Read fiction. Read science writing. Read anything that shows you the world is bigger than what fascists say it is.
Read to remember why your resistance matters. 📚💙

LLMs acting as participants on platforms like Prolific could pollute data meant to study humans. With OpenAI’s operator model, this issue is growing.
