tldr: we found very limited evidence for distress subsequently increasing belief in conspiracy theories using a longitudinal survey sampling participants 7 times over ~6 months - and no evidence for belief in conspiracy theories worsening distress over time
New research challenges the idea of a ‘vicious cycle’ between psychological distress and conspiracy beliefs
One prominent theory says conspiracy beliefs are triggered by elevated distress. But a new study finds limited evidence to support this claim.

Great news! Congrats to you both!

New report documents the difficulty for researchers to get access to social media data. The access challenge has multiple effects, such as turning away from studying some platforms, redesigning studies, and fears of violating terms of service.

Not disagreeing, but genuinely ignorant here -- a) what is the problem with 'sovereign citizen' as a broad label, and b) what is the best language to describe people with these kinds of beliefs, it feels relevant to the reporting on this story.

This is a nice write-up of our recent paper by PsyPost, with clear info about limitations and small effect sizes.

I would like to clarify that I am not in fact the person in the photo, though

Does microtargeting work? The idea that people can be manipulated by political messages that are furtively tailored to their personality or other vulnerabilities has triggered much concern. But how well founded are those concerns? 1/n

Thanks for your interest in the article, and I'm sorry it didn't address the points that you wanted it to. The underlying article was about comparing *broad strategic approaches* among island nations.

'A tendency to feel victimized predicts believing in conspiracies.'

That’s the TL;DR from @marlephie.bsky.social’s great summary of new research below. Backed by a huge amount of work and international data. Grateful to have been part of this excellent study. 👍

haven't posted in a while, so here goes.
recently had the opportunity to peer-review a thoughtful piece about autonomy and health-misinformation and #conspiracytheories (see here: linkinghub.elsevier.com/retrieve/pii...) & write a commentary on it (see below or authors.elsevier.com/a/1lPXr2dv7n...)

Conspiracies emerge in the wake of high-profile events, but you can’t debunk them with evidence because little yet exists. Does this mean LLMs can’t debunk conspiracies during ongoing events? No!

We show they can in a new working paper.

I had a great chat with @comingupcharlie.bsky.social about why some people reject germ theory in favour of alternative views like ‘terrain theory’, and make a brief appearance in this deep dive into the NZ influencers promoting these ideas. Well worth a read. 👇
The Baileys went from being conventional medical doctors to sovereign citizens who deny germ theory. They now have a popular Substack where they have advised cancer patients to not get chemotherapy and for people with mental illnesses to go off their meds www.thepress.co.nz/nz-news/3607...
The Baileys and their crusade against modern medicine
From their estate in rural Canterbury, former medical doctors have found a new calling: Trying to prove that viruses aren’t real.

Nice to see the work of the Science Media Centres highlighted by NBR review of Fox's book. But disagree with the reviewer on one point, NZ's @smcnz.bsky.social has in fact grown in scope and size, and is all the more important given fewer specialist reporters. www.nbr.co.nz/book-review/...

Trust is a super power. Climate scientists are trusted globally, just not as much as other scientists. Check out this excellent summary of our latest research that explores the reasons why:

New research shows climate scientists are less trusted than other types of scientists. But there are big differences between countries and specific groups of people.

It's often claimed that developing a belief in one conspiracy theory will increase the chance that someone goes on to believe other conspiracy theories... perhaps leading them down a rabbit hole of conspiracist beliefs. But does that really happen?

Does Developing a Belief in One Conspiracy Theory Lead a Person to be More Likely to Believe in Others?
The monological belief system model suggests that—for at least a subset of people—developing a belief in one conspiracy theory will cause them to be more likely to believe in others. This model has b...

I know it often feels as if scientific evidence doesn't matter any more, but a global survey of 72K people in 68 countries shows most of us trust science, and 79% of NZers want scientists to tell us about their research; by Laura Kranz & @scicomguy.bsky.social theconversation.com/despite-fear...
Despite fears of falling trust in expert knowledge, a global survey shows New Zealanders value science highly
Even if there’s no acute crisis of trust in science, we shouldn’t minimise the disproportionate impact vocal minorities who distrust science may have on policy and society.
