It's a shame the county decided not to install a warning system (e.g., sirens) along the Guadalupe River. Here's a 30-yr-old graph showing the benefit of warning time for forceful floods w/ pop. at risk = 1000. Would love an update based on more data.

Wonderful paper! For more on purposive variation, see this 2022 paper on metastudies: journals.sagepub.com/doi/10.1177/...

It's like Simonsohn et al.'s new mix-and-match method, but with more attention to moderation, generalizability, and statistical power.

New PsyArXiv preprint! osf.io/preprints/ps...
Risky-choice framing effects persist when option descriptions are matched in gains and losses and even when the options are completely described.
(Last year's Psych Science results replicated nicely in a larger census-matched sample!)

Got that end-of-the-year paper submitted a day early!
Framing Effects in Choices with Somewhat Risky Options [not just certain and all-or-none options], with former undergrad Prachiti Garge. osf.io/preprints/ps...
Expectation-based theories (especially TAX) fared better than categorical accounts.

Our recent Psych Science results replicated perfectly in a larger census-matched sample. Take that, reviewer 2!
