🚨📄 New paper (conditional accepted at @thejop.bsky.social):

We test whether social desirability bias actually distorts answers in online surveys.

Short version:
It mostly doesn’t.

I understand why people are exhausted by AI hype, and why those of us squarely in the corner of "human dignity uber alles" see AI doomerism as self-serving hype, but I *really* think people on the left broadly need to start thinking seriously about the possibiltiy of the hype being...true.

Was TikTok blocking certain political posts last week?

We investigated & found no systematic evidence of political censorship on TT post-restructuring at this point. A server outage better explains the data. But the story isn't over, and platforms need to provide the public more transparency.

Was there censorship on TikTok after the U.S. takeover?
A TikTok outage more likely explains recent anomalies – there’s no evidence of larger platform changes so far.

New preprint! So, what's a multiverse analysis good for anyway?>

With @jessicahullman.bsky.social and @statmodeling.bsky.social

juliarohrer.com/wp-content/u...
What’s a multiverse good for anyway? Julia M. Rohrer, Jessica Hullman, and Andrew Gelman Multiverse analysis has become a fairly popular approach, as indicated by the present special issue on the matter. Here, we take one step back and ask why one would conduct a multiverse analysis in the first place. We discuss various ways in which a multiverse may be employed – as a tool for reflection and critique, as a persuasive tool, as a serious inferential tool – as well as potential problems that arise depending on the specific purpose. For example, it fails as a persuasive tool when researchers disagree about which variations should be included in the analysis, and it fails as a serious inferential tool when the included analyses do not target a coherent estimand. Then, we take yet another step back and ask what the multiverse discourse has been good for and whether any broader lessons can be drawn. Ultimately, we conclude that the multiverse does remain a valuable tool; however, we urge against taking it too seriously.
