What this study supports
Supports the claims that replication effects were about half the size of the original effects and that 36% of replications were statistically significant versus 97% of originals. Graded D because it mixes experimental and correlational replications and describes research practice in a sample of journals, not an intervention; what counts as a successful replication is itself debated.
