Experimentology cover: title and curves for distributions.

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

Great study! Really interesting that the previous findings are now reversed. We need more replication (& extension) studies like this in the social sciences!

My co-authors and I just published a paper!

Our questions?🤔

(1) Whether a gender bias that was first documented 20 years ago would replicate, and if so...

(2) Whether its magnitude would depend on whether the women in question were Black rather than White.

Seems the White House is using gen AI to write their scientific reports, leading to the hallucinations and mistakes you'd expect. Laughing/crying right now.

@urisohn.bsky.social reanalyzed the AER paper data and concluded that the key results were mainly driven by confused participants.

Climate Terminology Does Not Matter Our new paper finds that swapping out one climate term for another does not meaningfully change people’s stated commitment to fight climate change

Climate Terminology Does Not Matter

Across tens of thousands of participants in two large-scale experiments, we found that labeling climate change in different ways had no effect on their stated willingness to act.

YouTube video by CBC News Is Trump right about the U.S. 'subsidizing' Canada? | About That

IMPORTANT: If you live in the United States or Canada, you’ve probably heard Trump‘s constant claim that the United States is “subsidizing” Canada. It’s wrong of course, but here’s the best explanation I’ve seen about how & why it’s wrong. PLEASE WATCH & SHARE IT A LOT. Kudos to Andrew Chang & CBC.

Underreported: Elon just picked the head of NASA—a massive conflict-of-interest that will damage a government entity that he partners with, depends on, and in some cases competes with. The nominated NASA director is a high-school dropout billionaire who is pals with Musk. He has no business at NASA.

Great write-up! Thank you!

The Business-School Scandal That Just Keeps Getting Bigger The rot runs deeper than almost anyone has guessed.

the fallout from the Francesca Gino research misconduct scandal isn't over. @engber.bsky.social writes about how an effort by some of her colleagues to self-audit their work with her ended up raising even more questions — for them personally and their whole field www.theatlantic.com/magazine/arc...

The superendowment effect—research by Winegar and Sunstein finds users would demand $80 to share personal data, but pay only $5 to keep them private. This raises questions over the reliability of WTP/WTA to gauge the welfare significance of giving up or maintaining privacy: https://buff.ly/3Oa5jvr

It’s insane that I got all the way through getting a PhD before I encountered equivalence tests. These should be part of every intro stats curriculum that covers NHST.

Another shoe just dropped in the ongoing Dan Ariely scandal: JMR, a top 4 marketing journal, has issued a formal “Expression of Concern” for Mazar, Amir, & Ariely (2008), the infamous Ten Commandments study

I love this!! Definitely going to give this mnemonic to students when I teach stats in a few months.
