ABSTRACT

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.
