How common are “survey professionals” - people who take dozens of online surveys for pay - across online panels, and do they harm data quality?

Our paper, FirstView at @politicalanalysis.bsky.social, tackles this question using browsing data from three U.S. samples (Facebook, YouGov, and Lucid):

In the Global South, WhatsApp is more popular than X or Facebook.

New in @The_JOP, we ran a WhatsApp deactivation experiment during Brazil’s 2022 election to explore how the app facilitates the spread of misinformation and affects voters’ attitudes.

🚨 Paper now as "just accepted" at @The_JOP. We ran the first WhatsApp deactivation experiment focused on multimedia content ahead of the 2022 election in Brazil. We find a reduction in users' recall of false rumors -- and, to a smaller degree, of true news. Null effects on attitudes. Full thread ⬇️

Much has been shown on fact-checking effects on the ability to discern true from false. But.. does it affect the fact-checker's perceived reputation and ideological leaning?

Really great piece!
I was planning to sit out the current round of tech-criticism internet drama.

But I always read @caseynewton.bsky.social, and I think he misses a key point about market power and the purpose of tech criticism.

TL;DR: we shouldn't grade the tech barons on a curve.

Among other things, US higher education effectively exports tens of billions worth of dollars of services, by persuading foreigners to pay a lot for a product that keep jobs in the US. How long more will they keep paying when they can't be sure they can even enter the country.
