🌱 Higher perceived complexity around climate mitigation was associated with lower policy support and intentions to act. Check out @saarataavila.bsky.social's awesome new paper on how perceived complexity can be measured (subscales: effectiveness uncertainty, trade-offs, and goal conflict).
My first paper is out at Journal of Environmental Psychology! 🌱
Climate change is complex: there are many variables that are connected via unclear causal relationships. But is awareness of complexity helpful in guiding people towards effective environmental behavior, or can it hinder action? (1/5)

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/...

Washing synthetic clothes is a major source of microplastic pollution. Citizen science can help understand which behaviors & materials cause most emissions, like through at-home data collection. We asked: Does participation also boost pro-environmental motivation? 🧵
