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/...

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.
