It’s not that people doubt biodiversity is declining—it’s that we underestimate how many others already share this concern.

In our new Perspective, we review work on pluralistic ignorance and set out a research agenda to:

Results from study of mental health in 92 countries (n>53,000): People are not doing well.

- U-shape for age is gone: Young adults lowest health, highest illness
- Education still matters (a lot)
- 45% of older people live alone
- Hybrid work > 100% remote or in-person

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)

“Prompting people to actively notice birdsong, plant textures and smells can significantly improve wellbeing…”

Interesting study that suggests simple and small interventions, eg signage, that encourage people to notice nature can boost people’s wellbeing.

🦋🌱 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)

Thanks @janakoehler.bsky.social for leading this excellent work! 🪧🌎🔥

In two studies, we find that:

1️⃣ the German public misperceives what the public thinks about climate activists.

2️⃣ marchers/gluers think they are perceived more negatively/positively by the public than they actually are.
1/7 🧵 We live in a biased social reality! 🤯

🚨 NEW PAPER: Climate activist stereotypes among the German public and German climate activists.

Climate journalists broke a big story during Earth Week with the launch of The 89 Percent Project: Between 80% and 89% of people around the world want their governments to do more on climate change, but, critically, this overwhelming majority doesn't realize its the majority.
