1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

While misinformation is often assumed to directly affect behaviour, experimental tests of this hypothesis are rare. We examined effects of a single exposure to misinformation on political and non-political behaviours. Study 1 participants (N = 2,397) were exposed to a fabricated news story about food contamination, with a subset (n = 143) subsequently invited to taste the targeted foods in a laboratory setting. Exposure to the fabricated story did not significantly affect attitudes towards or consumption of the target food. Study 2 (n = 417) confirmed that results were not specific to the particular story presented. Finally, Study 3 (n = 413) tested effects of misinformation about climate change. Exposure to climate-skeptical misinformation reduced signatures on an online petition, but had no effect on two other targeted behaviours. We conclude with a call for further experimental research to delineate the conditions under which misinformation does and does not affect behaviour.
