I'm excited to share the news that our climate change project won the @spspnews.bsky.social Robert Cialdini Prize for a "paper that uses field methods and demonstrates the relevance of social psychology to outside groups and communities"!

@waiterich.bsky.social — here’s a few food transition facts I LOVE ⬆️

Widespread diet change is not new. Don't tell me we can't green the food system 🥗

A history lesson ⬇️

🥔 ~1500s. Potatoes are introduced to Europe: Initially nicknamed ‘devil’s apples’, people suspected potatoes were poisonous. Nowadays, traditional European cuisine is unimaginable without it

New paper just dropped:

Szaszi, Barnabas, Daniel G. Goldstein, Dilip Soman, Susan Michie. (2025). Generalizability of Choice Architecture Interventions. Nature Reviews Psychology.

Thanks to @szaszibarnabas.bsky.social for doing the lion's share!

1️⃣ We are also guilty of over-generalizing behavioral measures. Especially across domains: e.g. donating to a green charity ≠ reduce meat consumption ≠ taking the bus ≠ etc. How are we feeling about that challenge?

2️⃣ How are we feeling about self-report climate actions as a quasi-behavioral measure?

Big fan of this @fdabl.bsky.social 👀

I'd love to pick your brains about a few related Qs about how tricky measuring green choices can be ⬇️

In our now published letter in @pnas.org, we raise two wider issues for behavioral science:

1) Intentions are poor predictors of behavior
2) Effects on intentions need not generalize to effects on behavior

We join calls for researchers to measure actual behavior: www.pnas.org/doi/10.1073/...

Despite all the negativity in parts of the press:

Change is happening. It’s not a straight line but things are moving.

More and more people understand that relying on increasingly volatile and expensive fossil fuel imports is not a viable pathway.

*COUGHS LOUDLY*

Climate literacy is critical for future business leaders—and MBA programs are evolving to meet this challenge, says Professor Bruce Usher.

Understanding these "six truths" - it's real, it's us, experts agree, it's bad, others care, and there's hope - predicts pro-climate attitudes and support for climate policies, @yaleclimatecomm.bsky.social finds.

In particular, (see next post) ...

The mission to update with the most recent evidence.. ⛰️📚🤯 But I'm game. Let's chat!

A brilliant idea — I’m game 👀

But what I like most about this paper?? 👀

The LEAST informed about green choices benefit the MOST from learning about impact 📈

It turns challenges like 'low carbon competence' into an opportunity for big change ⬇️

🔗 www.nature.com/articles/s41... @elisugerman.bsky.social, @ericjjohnson.bsky.social

... and this can extend to showing people precisely what to do to be greener ⬇️

Climate psychologists are often the first to say: ‘information alone doesn't change green behavior’ ❌

But, we are wrong.

You can do a lot of heavy lifting just through education, especially about what the correct green action is! ⬇️

Huge thanks to @kristiansn89.bsky.social, @dgoldwert.bsky.social, @madalina.bsky.social, @mattgoldberg100.bsky.social and Yash Patel 👏👏👏

♻️📣 Telling. people. about. how. green. their. actions. are. helps. them. to. make. green. choices. 📣♻️

🆕New data shows: education helps the least informed most. The more wrong you are about an action’s impact 🌍 the more you shift it once you learn the truth 📊⬇️

This is so cool guys. I can't update slides quick enough to keep up 👏✍️

🧠🌍 Can you correct misperceptions of the impact of different climate actions?

In a new @pnasnexus.org paper, we tested whether climate action literacy interventions can shift behavioral commitments toward more effective climate actions. Check out our neat results 🙂

Thanks!!

✨New✨ climate report makes one thing clear about Net Zero...

🔋Electrification

Behaviorally:

📈 37% of CO₂ reductions come from household behavior changes

📈 72% of these reductions come from electrification: EVs (40%), heat pumps (30%).

Chuffed to be cited 😊

Study on London 20 mph limits shows:
- collisions ⬇️ 35%
- casualties ⬇️ 36%
- fatal/serious injuries ⬇️ 34%
- child casualties ⬇️ 46%
- child deaths ⬇️ 75%
- walkers, cyclists, motorcyclists killed/seriously injured ⬇️ 28%

One of my all time favourite reports includes this attempt at summarising the benefits from investment in active travel.

It’s one of the best investments a government can make - something acknowledged within many of DfTs own reports.
