Alex Chan shares an updated take on how much opt-out organ donation matters. Does switching to this policy actually increase organs donated? Only in countries where consent is interpreted strictly (without requiring the additional consent of next of kin). @pennchibe.bsky.social

Great talk from Stefano Della Vigna at @pennchibe.bsky.social conference about forecasts of social science experiments’ effects. We expect effects that are roughly 2x as big as we get.

The best-performing reminder campaign sent weekly emails to customers who hadn't made a savings deposit in the last week nudging them to save, and those who had already made a deposit were congratulated. This campaign boosted monthly one-time savings deposits by 1.32%.

🚨NEW PAPER ALERT🚨
Can reminder emails compel Americans to save? We ran a 2 million person megastudy with a large US bank to find out. Our results published today in @pnasnexus.org suggest that the answer is: yes, probably, a little. 🧵

If you’re confused about why studies of the effects of Tylenol in pregnancy have disputed implications, you may want to better understand selection bias. This q&a (which doesn’t cover tylenol) could help! katymilkman.substack.com/p/what-is-se...

Congratulations to the fabulous @colinmfisher.bsky.social on publishing THE COLLECTIVE EDGE! It’s a fantastic playbook for how to build successful, synergistic teams (brought to you by an amazing researcher whose work on synergy is inspired by being a jazz musician on the side!).

In case you missed it, my favorite book of the year so far dropped earlier this month. Be sure to grab a copy. And lest you’re tempted to jump to conclusions from the cover, fyi: it’s is an evidence-based book by two economists that’s pro-environment and pro-reproductive freedom.
