Long Covid has high prevalence and impact: Where is the Government response? Long Covid's impacts on health, social, and economic justify a well-coordinated national response focused on prevention, people-centred care, and research.

More than 400,000 New Zealanders have experienced Long Covid and nearly half are still symptomatic.

Long Covid is a stark reminder of the pandemic’s persistence with real and ongoing health, social, and economic impacts.

So where is the government response?

Survey research is often interpreted as showing that belief in conspiracy theories can be surprisingly widespread, including belief in conspiracy theories that would be astonishing if true. For example, in The Atlantic we learn that “12 million Americans believe lizard people run our country”

Scientists who use AI published 3X more papers, received 5X times more citations, and reached leadership roles faster than their AI-free peers.

But science as a whole is paying the price. AI-driven work circles the same crowded problems, are leads to a less interconnected scientific literature

Abstract
Objective

Anti-science sentiment has the potential to become a major societal problem, and research has started considering the psychological and ideological antecedents of science rejection of novel science and technologies. Precision Health (e.g. human genetic mapping, health data digitalisation and access, wearable devices and digital apps) aims to pre-empt disease onset through the development of proactive, personalised solutions to health problems.
Methods and Measures

In a preregistered study using a national sample of adult Australians (N = 997) we predicted attitudes to 10 Precision Health science areas from socio-demographic and psychological variables.
Results

On average Australians were positive towards precision health technologies (Ms = 5.03–5.66, 7-point scale). Increased institutional trust in health, science, and medicine (B = 0.49, SE = 0.04) and being older (B = 0.004, SE = 0.002) significantly predicted positive attitudes. Institutional trust in governments, conspiracy belief, social dominance orientation, right-wing authoritarianism, tertiary-education level, importance of religion/spirituality and political ideology did not.
Conclusion

The majority of Australians were favourable towards Precision Health, with institutional trust playing a key role in positive attitudes. We note the importance of understanding the role of social and ideological antecedents of science opposition now, and going forward with the development of technologies.

Abstract
Research seeking to explain why people believe conspira-
cies has largely focused on intrapsychic factors, but there is
growing research examining structural-level elements of dis-
advantage. The socio-functional model of conspiracy belief
(Adam-Troian et al., 2023, British Journal of Social Psycholog y,
62, 136) posits that subjective feelings of permanent inse-
curity arising from objective material strain (i.e., precarity)
cause conspiracy belief directly or indirectly through insti-
tutional distrust. Across three preregistered studies using
observational longitudinal designs over 3 (n = 637) and
11 months (n = 832), and a between-group experimental de-
sign (n = 285), we use various methods to estimate causal ef-
fects for this proposition during the current cost-of-living
crisis. In Studies 1 and 2 using random intercept cross-
lagged panel models, we find no evidence that increases in
precarity temporally precede increases in conspiracy belief
(or vice versa) but find stable between-persons effects over
time. In Study 3, despite successfully manipulating precarity
using a self-imagine paradigm, we find no direct or indirect
effect on conspiracy belief through decreased government
trust. We discuss the importance of using methods that per-
mit credible causal inferences and key directions for future
studies investigating the socio-functional model.

Common left-right political scale masks anti-establishment views at the center A new study in Political Psychology challenges the idea that political centrists are uniformly moderate. The findings suggest the scale’s midpoint hides a diverse group of individuals, including those with strong anti-establishment and populist beliefs.

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.

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

No access ⛔

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.

'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. 👍

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.
