Finally, we found that people who believe climate change is man-made and support policies to protect the planet had higher pro-environmental motivation specifically.

People lower in trait apathy and who rated the task as less effortful were more likely to help both causes.

Using computational modelling, we showed that these effective interventions changed how rewards 💰 for the climate 🌍 (vs. food charity) were devalued by effort 💪.

This was independent of how noisy participants' choices were 🤔

Two interventions robustly decreased the preference to help food over climate, across measures and analyses.

These interventions:
- decreased psychological distance to the negative effects of climate change
- used system justification theory to promote pro-environmental action

We tested the 11 expert-sourced interventions from the International Climate Psychology Collaboration led by

People were more willing to exert effort when:

💪 the effort required was 🔽
💰 the reward available was 🔼

In the control group without intervention, motivation was higher to provide food than mitigate climate change 🌍

➡️ Interventions that promote climate motivation are key

3,055 ppts from 6 countries 🇧🇬🇬🇷🇳🇬🇸🇪🇬🇧🇺🇸 did our new online Pro-Environmental Effort Task ✨ the PEET ✨

On each trial, they choose between rest or work: exerting effort by clicking boxes to earn more credits 💪

Credits were donations to a climate charity 🌍 or a matched control food charity
