Fig. 5: Accuracy prompts reduce sharing to the extent that headlines are perceived as inaccurate.

For each of the 357 headlines in the 15 experiments where out-of-sample accuracy ratings were available, the accuracy prompt effect (sharing when treated minus sharing in control) is plotted against the headline’s perceived accuracy. False headlines are shown in green, true headlines in orange. Dot sizes are proportional to sample size. Best-fit line and 95% confidence interval are shown.
