Meta is abandoning fact checking – this doesn’t bode well for the fight against misinformation Numerous studies have shown that fact checking has helped reduce the spread of misinformation and disinformation online.

Some reflections with colleagues @nedwatt.bsky.social and @riedlinm.bsky.social at @theconvo-bot.bsky.social on Meta's decision to end its professionally funded fact-checking model in its platforms and adopt the X crowdsourcing model with a new 'community notes'👇 theconversation.com/meta-is-aban...

The establishment of the "Russian Fact-Checking Association" marks a significant escalation in the weaponisation of fact-checking. edmo.eu/publications... If you're interested in this topic, I recommend reading the recent article published in Media and Communication. More information in the thread👇

Beyond charting the work of fact-checkers in non-WEIRD countries, our discussion calls for future research into platforms' mechanisms for governing facts and knowledge itself, much of it now subjected to fact-checking frameworks and content moderation routines.

The paper draws from interviews with 37 fact-checkers from 27 countries outside the WEIRD region (Western, Educated, Industrialized, Rich, and Democratic).
 
We probed the relationship between social platforms and non-WEIRD fact-checking organizations and their influence on fact-checking practices.

Delighted to share this paper with my PhD advisor @toledobastos.bsky.social , now published open access in New Media & Society.
