About FReD Explorer

The FORRT Replication Database (FReD) is a comprehensive collection of replication studies in psychology and related fields. This Explorer app allows you to browse, filter, and visualize replication outcomes using various success criteria.

Success Criteria

FReD supports multiple criteria for assessing replication success:

Significance of Replication: Whether the replication effect is statistically significant in the same direction.
Aggregated Significance: Whether the meta-analytic combination of original and replication is significant.
Consistency with CI: Whether the original effect falls within the replication's confidence interval.
Consistency with PI: Whether the replication falls within the prediction interval.
Homogeneity: Whether original and replication effects are statistically homogeneous.
Homogeneity & Significance: Combined assessment of homogeneity and significance.
Small Telescopes: Whether the replication exceeds the effect giving 33% power to the original.
Reported Success: The outcome as reported in the replication study.

Welcome to FReD Explorer

The FORRT Replication Database (FReD) Explorer allows you to browse and analyze replication studies across psychology and related fields.

Use the filters on the left to narrow down studies. Select different success criteria to see how outcomes vary based on different definitions of replication success.

Note: You can download all data for further analyses. We also offer an R package that provides some functionality that goes beyond this Explorer. Check out the FReD R package.
