The truth about the truth: a meta-analytic review of the truth effect

Dechêne, Alice, Stahl, Christoph, Hansen, Jochim, Wänke, Michaela·2010·Personality and Social Psychology Review

Abstract

Repetition has been shown to increase subjective truth ratings of trivia statements. This truth effect can be measured in two ways: (a) as the increase in subjective truth from the first to the second encounter ( within-items criterion) and (b) as the difference in truth ratings between repeated and other new statements ( between-items criterion). Qualitative differences are assumed between the processes underlying both criteria. A meta-analysis of the truth effect was conducted that compared the two criteria. In all, 51 studies of the repetition-induced truth effect were included in the analysis. Results indicate that the between-items effect is larger than the within-items effect. Moderator analyses reveal that several moderators affect both effects differentially. This lends support to the notion that different psychological comparison processes may underlie the two effects. The results are discussed within the processing fluency account of the truth effect.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
