With @epronizius.bsky.social, @monabielig.bsky.social, @clauslamm.bsky.social, @protzko.bsky.social, Olena Vitkovska, and Celina Kacperski, we'll explore the ethical tensions, institutional constraints, and political risks of doing science across borders—especially in times of war or crisis.

🧠🌍 Big Team Science aims to make global science thrive. But what happens when collaborators come from countries in conflict? Or when researchers are unwilling, unable, or legally barred from working together? Join our online #BTScon2025 UNconference: "Big Team Science in a Divided World"

It is great to see the Manylabs Climate (ICPC) dataset being reused in new and important ways! @saschakuhn.bsky.social and @wilhelmhofmann.bsky.social looked more in-depth into the societal-level structures that shape public support for policy acceptance across the globe. More info 👇👇👇

Takeaway: If we want to improve behavioral science and intervention design, we need better ways of evaluating expert judgment—and clearer benchmarks. Forecasting experiments also give unique insights into how experts (and nonexperts) think and act!

120

Kim Doell @kimdoell.bsky.social · 16/05/2025

So what does this mean? ➡️ Being an expert helps—but it doesn’t guarantee accuracy. ➡️ Predicting behavioral outcomes is especially hard. ➡️ And heuristics can be more useful than expected.

120

Kim Doell @kimdoell.bsky.social · 16/05/2025

We also looked at who tends to be a better forecaster. The only consistent predictor across outcomes? Age. Older participants were more accurate. Other traits (e.g., open-mindedness, political orientation) mattered for beliefs and policy—but not behavior.

110

Kim Doell @kimdoell.bsky.social · 16/05/2025

That heuristic? Just assume the interventions do nothing. No effect. It turns out this "do nothing" model was surprisingly hard to beat—especially when predicting real behavior.

110

Kim Doell @kimdoell.bsky.social · 16/05/2025

How did they do? ▶️ Academics were more accurate than the public—especially for belief and policy outcomes. ▶️ But their predictions were less accurate for behavior. ▶️ However, nobody outperformed a simple heuristic model.

110

Kim Doell @kimdoell.bsky.social · 16/05/2025

We tested four groups: Academics (N = 242) Government officials (N = 23) Climate communicators (N = 23) General public (N = 574) We then compared their predictions to actual results from a nationally representative U.S. sample (N = 6,954).

110

Kim Doell @kimdoell.bsky.social · 16/05/2025

Forecasters were asked to predict how 11 climate interventions would impact: ✅ Beliefs about climate change ✅ Support for climate policy ✅ A costly pro-environmental behavior These weren’t hypotheticals—these were real interventions, with real data.

120

Kim Doell @kimdoell.bsky.social · 16/05/2025

🧵New preprint! Can experts accurately predict real-world effectiveness of 11 climate change interventions? We ran a preregistered forecasting study with 862 participants and compared their predictions to real-world outcomes from 6,954 Americans. What we found surprised us. osf.io/preprints/ps...

📣 We hope this work helps refine climate models and guide global interventions by: 🔹 Prioritizing modifiable psychological research targets 🔹 Accounting for national context 🔹 Emphasizing outcome specificity

100

Kim Doell @kimdoell.bsky.social · 09/05/2025

🧩 One size doesn’t fit all. Public vs private, easy vs effortful behaviors are driven by different factors. Designing effective interventions means targeting the right outcome with the right lever.

100

Kim Doell @kimdoell.bsky.social · 09/05/2025

⚠️ One of the most striking findings: Political orientation strongly predicts beliefs and policy support, but not actual behavior—and even predicts less info sharing. Is polarization appears more psychological than behavioral?

100

Kim Doell @kimdoell.bsky.social · 09/05/2025

Explained variance ranged widely: 🔹 Belief: 57% 🥳 🔹 Policy support: 46%🍾 🔹 Info sharing: 74% accuracy🎉 🔹 Actual behavior: just 10%🫣 Private, effortful actions are harder to predict—likely influenced by unmeasured situational factors.

100

Kim Doell @kimdoell.bsky.social · 09/05/2025

People in lower-HDI countries showed stronger climate beliefs and behaviors—supporting the precarity hypothesis that less affluent nations, with fewer resources to buffer climate impacts, are more attuned to the need for action.

100

Kim Doell @kimdoell.bsky.social · 09/05/2025

📊 Top 4 predictors consistently mattered across all outcomes: ✅ Environmentalist identity ✅ Trust in climate science ✅ Internal environmental motivation ✅ HDI Most other predictors had inconsistent or even opposing effects (positive relationship with one outcome, neg with another).

100

Kim Doell @kimdoell.bsky.social · 09/05/2025

We ranked 19 predictors across 4 climate outcomes: 1️⃣ Belief in climate change 2️⃣ Policy support 3️⃣ Willingness to share info 4️⃣ Actual effortful behavior (not self-report!)

Kim Doell @kimdoell.bsky.social · 09/05/2025

Most research on climate beliefs/behaviors is from Global North countries. We use data from the International Climate Psychology Collaboration (manylabsclimate.wordpress.com) to analyze diverse predictors across 55 countries, offering a very global perspective🌍

Today we had the honor of hosting @magdalenaboch.bsky.social at the @cbehav.bsky.social seminar series where we learned about what makes us social from a comparative neurobiology perspective 🐶🧠🤩

Kim Doell @kimdoell.bsky.social · 16/04/2025

I truly and honestly could not recommend this position more. If you're looking for a PhD, this is one I would DEFINITELY apply for!

In short: ✔ Climate change affects your brain ✔ Your brain drives climate action ✔ Neuroscience, in collaboration with manyyyyy other disciplines, can help us design better, smarter, more impactful solutions

100

Kim Doell @kimdoell.bsky.social · 09/04/2025

We outline a roadmap for using neuroscience to predict, test, and scale interventions — from neuroforecasting campaign responses to using brain stimulation 🧠⚡ to understand sustainable decision-making.

100

Kim Doell @kimdoell.bsky.social · 09/04/2025

And it's not just about individuals. Collective action — from community projects to global movements — can (likely) build social connection, reduce eco-anxiety, and activate the brain’s feel-good pathways.

100

Kim Doell @kimdoell.bsky.social · 09/04/2025

We also discuss how the brain’s decision-making and emotional systems are key to understanding why people act — or don’t — on climate. From fear to hope, reward to control: neuroscience reveals the hidden forces behind climate action.

100

Kim Doell @kimdoell.bsky.social · 09/04/2025

Taking climate action can actually boost brain health. Walk or bike more? Great for the planet and your prefrontal cortex. Eat less red meat? Better for your carbon footprint and your cognition. Nature-based solutions? Good vibes AND neural resilience.🌱

Kim Doell @kimdoell.bsky.social · 09/04/2025

Most people might not realize this, but climate change isn’t just bad for the planet — it’s bad for your brain. • Worse mental health • Increased chance of cognitive decline • Higher risk of neurological disorders But here's the twist...

Should we use "Climate Change", "Climate Crisis", "Global Warming" or another term for this environmental disaster?
