The US CDC changed its website's claims about #Autism and #Vaccines on November 19 2025. A high-powered experiment found the change caused differences in the perceived #risk and uncertainty about vaccination, trust in CDC, and reliance on #logicalFallacies (but not vaccination intention). 👇 Thread

Maybe it's unsurprising that #trust in institutions like the #CDC is decreasing in the #USA, but what about other countries? Well @gerrymolloy.bsky.social and colleagues found a similar trend in #Ireland (Figure 1 via Kevin below) and #Canada. #publicHealth #Science #medSky #SciComm #EHPS2026 #edu

Poolside coffee + fruit breaks are the way! Thanks for choosing this venue for #EHPS2026, @ehpsconference.bsky.social!

What about #measurement problems? A handout, presentation, debate, and discussion gave us lots to think about re: #Wicked Problems with #psychology scales Thx T. Cornelius, @matherion.mastodon.nl.ap.brid.gy, @mayabraun.bsky.social, @paulinaganucheau.bsky.social, schenk.bsky.social, and M. Johnston

Then we had a keynote about the history and future directions of #mHealth from from @profjanewalsh.bsky.social. Promising results #remoteMeasurement in remote areas. But not all interventions are panaceas! A "digital clinician" that seemed more knowledgable was also less satisfying or trustworthy?

How can underutilized tools advance #HealthPsychology? For example, can #AI enhance theory-driven #interview coding? Sumit Mehra et al's attempt found that when #LLM codes deviated from humans' they were usually MEANINGFUL or even ADDITIVE! And most remaining AI codes were identical to humans'!

What if #AI starts the analysis and humans review? Paulina Bondaronek shared 1) Machine Assisted Topic Analysis (MATA): doi.org/10.64898/202... 2) GRACE evaluation framework: doi.org/10.2196/prep... Dr. Bondaronek seemed unimpressed. Does the #preprints formally compare human and machine outputs?

*Correction: DO the preprints...? (Apologies for other typos I've missed.) Onward!

Can #eyeTracking advance #HealthPsychology? Dr. Athina Manoli shared an experiment suggesting that it can! My smartphone has issues that prevented me from capturing key slides, but you can follow Dr. Manoli on ResearchGate to be alerted when this is published: www.researchgate.net/profile/Athi...

What is the #healthy = #sustainable heuristic? Article: doi.org/10.1111/aphw... 🔓 At #EHPS2026, @katharinaeichin.bsky.social shared an(other?) experiment where people inferred foods' eco-friendliness from its #NutriScore — less so #EcoScore to healthiness. Preprint: doi.org/10.23668/psy... 🔓

Should #AI still be benchmarked against humans? Alex Gillespie’s #EHPS2026 keynote shared years of #research making sense of patient complaints with #LLMs. One upshot: models often reveal what humans *miss* — not all human #alignment is good! Follow on gScholar: scholar.google.com/citations?hl...

Should #health #psychology researchers embrace #LargeLanguageModels for #qualitativeAnalysis? The EQUAL folks organized a debate at #EHPS2026 to review evidence, arguments, objections, etc. for/against both sides.

👏🤓 (The pro-#AI position lost ground, but sustained the majority.) ehps.net/equal/

We're often not as #healthy as we feel (and vice versa).

 And that asymmetry predicts various #health outcomes. But does it predict #healthcare USE? "Feeling healthier than you are" predicted shorter #hospital stays (but not hospitalization). 🔓Calvey & Laurence: www.linkedin.com/feed/update/...

Do people think inherited = untreatable? When asked what one's main concern would be if their #genetics predisposed them to a #health condition, 25% said it would be that they “can’t do anything about it”.

 Bianca Cucos et al. think personalized risk messaging could help. doi.org/10.1093/eurj...

Ever feel familiar with or concerned about stuff you don’t understand? Most respondents were (rightly) worried overuse of #antibiotics makes them less effective. But many thought #AMR was a #health condition (not a bacterial trait). Follow Dr. Palacz-Poborczyk at www.linkedin.com/in/iga-palac...

One reason #antibiotics are overused is "diagnostic uncertainty". An #rapidTesting can quickly increase certainty. So @isilcoklar.bsky.social et al. have been talking to clinicians and patients to find ways to increase use of point-of-care, C-Reactive Protein #diagnostics More: lnkd.in/p/e5uV4Yg5

*AND* rapid testing… (Not being able to correct my typos is one of many reasons I often regret threading on this website.) More posts from EHPS in the pipeline!

How can we help people understand #risk? 

Some evidence favors #iconArrays (that visualize outcome frequencies) But what if we added a patient narrative to those #graphics? 

A small experiment found #narratives actually *worsened* factual recall! Follow via www.researchgate.net/profile/Made...

If disagreement improves, say, #socialCohesion or #openMindedness, how can we help people engage in it?

 An experiment found planning may help.

 But self-reported #intellectuallyHumility predicted being *less* likely to change minds? Follow Dr. Scholz on RG: www.researchgate.net/profile/Chri...

If #AI can enhance diagnostic accuracy, why might some physicians not adopt it? Dr. Kritz et al. found what you might expect, such as #health systems that block #LLMs, insufficient training, and being more than 50 years old. 📃 doi.org/10.2196/80274 👤 www.researchgate.net/profile/Marl...
