Summary

97% of original studies had statistically significant results.
47% of original effect sizes were in the 95% confidence interval of the replication effect size.
39% of effects were subjectively rated to have replicated the original result.
36% of replications had statistically significant results.

The claim that “we already know this” belies the uncertainty of scientific evidence.
