Serious scholars have examined what happens when we change the number of H1-B visas issued.

Cities that get more H1-B immigrants subsequently see the wages of natives *rise* substantially.

Skilled immigrants bring new ideas, fill labor shortages and make us all more productive.

More toxic #Twitter posts from US Members of #Congress (MCs) were more likely to be reposted by liberal users — especially toxic posts about #Republicans.

This and more among 13,000,000 users and 1,300,000 posts from 2009 to 2019.

Legislators & staffers have a bias toward thinking the public is evenly divided on policy issues, rather than a conservative bias in perception; prior findings were based on policy questions where the liberal position was more popular

Here is a ‘blame-praise curve’ for the percentage of household chores done by husbands

People think husbands are blameworthy if they do 20%, but praiseworthy if they do 40% (!)

Perceived average is above 40%, so people think below average is still praiseworthy

We did this whole debate with terrorism post-9/11.

I even ran a study testing it. In fact, no, providing accurate info about the extremely low personal risks posed by terrorism on U.S. soil led to people having much more accurate beliefs. Some even thanked us for the chance to learn in the debrief!

New in TiCS w @dgrand.bsky.social @gordpennycook.bsky.social

It’s been ~10yrs since misinfo research exploded but our paradigms are stuck in the post-2016 “fake news” model

Time for new approaches:
o True/False → Content that misleads
o Belief → Behavior
o Eval interventions in ambiguous settings

We built the simplest possible social media platform. No algorithms. No ads. Just LLM agents posting and following.

It still became a polarization machine.

Then we tried six interventions to fix social media.

The results were… not what we expected.

Can We Fix Social Media? Testing Prosocial Interventions using Generative Social Simulation
Social media platforms have been widely linked to societal harms, including rising polarization and the erosion of constructive debate. Can these problems be mitigated through prosocial interventions?...
