Most of us support greener yards, but that support rarely shows up on the street. EP Post doc Tabea Hoffmann (+ @sandrajgeiger.bsky.social, Jan Willem Bolderdijk & Ward Rauws) tested a "norm-seeding" intervention: residents who signed up to replace tiles with plants could put up a yard sign:

Insights from climate psychology for misinformation research
Nature Human Behaviour, Published online: 20 July 2026; doi:10.1038/s41562-026-02530-4Climate change and misinformation are interconnected global crises shaped by tensions between individual, collective and vested interests. Drawing on climate psychology, we distil six insights for misinformation research to strengthen policy relevance, systems thinking and resilience to attacks.

Dass "die Leute interessieren sich nicht für die Klimakrise" ein sehr erfolgreiches Stück Meta-Desinformation ist, zeigt übrigens nicht nur der Hamburger #Zukunftsentscheid. Die (nationale wie globale) Studienlage ist völlig eindeutig.Die Leute wissen, was los ist (Text von Juli)
Forschung gegen gefühlte Wahrheit
Die Deutschen haben keineswegs die Nase voll vom Klimaschutz
Eine Kolumne von Christian Stöcker
Niemand interessiert sich mehr für die größte aller Krisen? Falsch. Das zeigen Forschungsdaten ebenso wie ein Erlebnis in meinem Motorradunterricht.

💡Why? A single message isn’t enough. People need to hear it from many others—like you. 𝐓𝐡𝐞 𝐠𝐨𝐨𝐝 𝐧𝐞𝐰𝐬: 𝐲𝐨𝐮’𝐫𝐞 𝐩𝐚𝐫𝐭 𝐨𝐟 𝐚 𝐠𝐥𝐨𝐛𝐚𝐥 𝐦𝐚𝐣𝐨𝐫𝐢𝐭𝐲. One that can be louder, more visible, and more connected. And that shift, from silence to solidarity, is exactly what the climate movement needs right now.

🌱 To test whether breaking this illusion can spark #action, we told half of our participants that 71–88% of their fellow citizens believe climate change is real and humans are responsible. Hearing this didn’t immediately make people more willing to change their lifestyle or support climate action.

Sandra Geiger @sandrajgeiger.bsky.social · 24/09/2025
🌏 Everywhere we looked, the same pattern emerged: a collective illusion where climate believers think they’re swimming against the tide when in fact they’re riding the wave. The real misunderstanding isn’t about the facts or hard science—it’s the belief that people are divided on the issue.

🦋🌱 Most people care about #biodiversity, yet we often underestimate how concerned others are about its loss. This “pluralistic ignorance” can silence people, weaken action, and make ambitious policies seem less popular. In a new paper, we outline a research agenda to study and reduce this gap (1/2)
