Misinformation research has a causality problem: lab experiments are limited; observational studies confounded.
We used causal inference on 9.9M tweets, quantifying effects in the wild while blocking backdoor paths.
Does misinfo get higher engagement? Are following discussions more emotional? 🧵

Further robust evidence suggesting green nudges at the individual level are unlikely to make a difference. As we recently suggested, it is time to abandon the prevailing success focus and rather think of this body of evidence as pointing to the many structural constraints people are facing, and

Too often, I see people talk about a replication as if the first study has established something, and the replication study is a double-check. What people often fail to understand is that we do not do replication studies to *check* a finding, but to *establish* a finding. 1/x

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/...
