Credibility Beyond Replicability: Improving the Four Validities in Psychological Science

Psychological science’s "credibility revolution" has produced an explosion of metascientific work on improving research practices. While much attention has been paid to replicability (reducing false positives), improving credibility depends on addressing a wide range of problems afflicting psychological science, beyond simply making psychology more replicable. Here we focus on the "four validities" (Shadish et al., 2002) and highlight recent developments aimed at improving these four validities in psychology research, many of which have been led by early career researchers. We propose that the credibility revolution in psychology, which has its roots in replicability, can be harnessed to help psychology improve its validity more broadly.
