The front cover of a report called Testimony Evaluation in criminal cases review commission casework. There is a logo of the evidence based justice lab and the University of Exeter, and two legal icons of a court building and a judge.

Restrictive rules surrounding review by the Criminal Cases Review Commission are preventing the efficient identification of some miscarriages of justice, says a new study by Prof. @rebeccakhelm.bsky.social Dir of the Evidence-Based Justice Lab and Dr @emilyspearing.bsky.social

We know how to win hearts & minds in support of climate action, but we need to put much more effort into actually communicating the proven-effective messages. Folks, time's a wastin'.

This is coming up and I thought I'd boost it again with the little test tube icon: 🧪

We show that event-specific climate misinformation - i.e. claims that arson caused Australia’s 2019–20 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.

Published today: One of the biggest #science #communication studies to date. We asked 71,922 people in 68 countries how they #engage with information about #science and combined the data with several country-level factors: journals.sagepub.com/doi/10.1177/... #OpenAccess

Happy to share our new research on AI-generated visual misinformation - we find that specific media literacy tips about AI images improve misinformation discernment over general tips about fake news.

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 Misleading Panic over Misinformation People can’t agree on how to define misinformation and its related terms, making regulation nearly impossible. Instead, free expression serves as a better tool for discovering truth.

Hey Australia, let's stay out of this one, yeah?

As the media works to win trust, people say they want the truth Australians want journalists to tell the truth. Is that a simple request?

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/

Next is @ulliecker.bsky.social on misinformation spread in communication chains. Rather than look at transmission from one to many (eg social media), look at peer-to-peer transmission of misinformation corrections (game of telephone). #sarmac2025 21/

Next @emilyspearing.bsky.social on AI-generated misinformation, its influence and how to correct it. Expected more misinfo reliance in human and AI condition, inoculation would reduce beliefs, trust boost would increase belief and disclaimer would have no impact.
