Start watching a bunch of really weird films. Or better, really great, under-appreciated ones. Like Sorcerer.

A nearby restaurant has the following appetizer on their menu: donuts drizzled with truffle oil, covered in pecorino and parsley, served with marinara sauce. $10.

nice context for some of the progress the country has made over the last 80-odd years on racial/ethnic prejudice.

Yep, and a couple of orders of magnitude faster (effectively independent draws from the posterior per unit of time) than what it replaced!

Have you put it on a preprint server yet? It wonder if you put the study design on the social science prediction platform, get a bunch of people to predict some nonzero effect, then include in your paper that a null result is interesting and unexpected

So one of our key findings was the size of environmental damages from satellite constellations determines whether the market will make them too big or too small relative to what's socially optimal

Some evidence on those damages here: https://www.pnas.org/doi/full/10.1073/pnas.2313374120

From yesterday's exhibits in US v. Sam Bankman-Fried:

The prosecution shows that the "insurance fund" that FTX bragged about was fake, and just calculated by multiplying daily trading volume by a random number around 7500

I've developed a new forecasting tool! You tell me what your education intervention is, including the full details of how it changes teacher and student behaviors. Then I use advanced AI methods to predict that the effect size is 0.1 SDs.

Fun story: went to Cuba in 2010. The only evidence there that the US existed was Tabasco and Inglourious Basterds, which somehow escaped the censors.

Re: recent discussion about Katalin Kariko--
In 2009, Carol Grieder won the Nobel Prize for her work on telomeres. That same day, she got a notification that her NIH grant proposal was deemed not worthy of discussion due to "limited preliminary data."
