We show that event-specific climate misinformation - i.e. claims that arson caused Australiaโ€™s 2019โ€“20 Black Summer fires - distorts reasoning and donation behaviour. Corrections mitigated these effects, especially when highlighting multicausality of extreme weather events.

I hear a lot about misinformation as a "symptom" of "distrust". Here we test this & find that while trust is important, it doesn't buffer: misinfo isn't mitigated by high trust. Both misinfo & distrust *independently* predict vaccine denial. It's a disease of its own!

Having to go to some chatbot to get misinformation is such a waste of time. That's why we need to put this right in the browser so you can get your misinformation faster.

AI summaries kill search traffic. This has been an obvious consequence of Google's AI summary strategy since its inception.

Apparently the training data is so valuable that Google is willing to risk the neck of the goose that lays golden eggs.

The Impacts of Intent and Uncertainty on Source Credibility Following the Correction of Misinformation Mitch Dobbs

Finally Mitch Dobbs on how correcting false claims can affect source credibility. Why do we see differences between politicians and doctors (corrections decrease trust in lying doctors but not politicians)? Possibly differences in initial trust. #sarmac2025 26/
