Managing the terror of publication bias: A comprehensive p-curve analysis of the Terror Management Theory literature
Open accessAbstract
A key prediction of Terror Management Theory is that people affirm their cultural worldview after they are reminded of death. This mortality salience (MS) hypothesis has been widely explored, yet the presence of questionable research practices may impact the replicability of this literature. We assess the evidential value of the MS hypothesis by conducting a pre-registered p-curve analysis of 860 published studies. Our results suggest that there are nonzero effects in this literature and that power is larger for studies conducted with multiple delays between the independent and dependent variables, for studies that test for main effects in comparison to those that test for interactions, and for studies conducted more recently. However, since the estimated average power of MS studies is 26%, direct replications are unlikely to succeed. We recommend researchers consider our evidence when planning their samples, and that they anticipate smaller effects by increasing their sample sizes.

The Power and effect size estimates section (page unavailable) infers illustrative effect sizes of d = 0.25 and d = 0.35 from the p-curve. It does not compare those estimates with the citing paper’s observed effect size, which is not specified here, and explicitly says the p-curve does not yield a straightforward average effect-size estimate.

Experimental — accuracy not yet measuredAs TMT can explain various and opposing consumer responses, questionable research practices may have been employed, specifically HARKing.
“As the theory can explain various and opposing consumer responses, questionable research practices may have been employed, specifically HARKing (hypothesizing after results are known), as also suggested by Chen et al. (2022).”

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.
