TL;DR. In Simonsohn’s Small‑Telescopes framework you test whether the true effect is smaller than the effect that would have given the original study 33% power (call this \(d_{33\%}\)). Simonsohn (2015) shows that this requires 2.

We defined, collected, and categorized 40 questionable research practices (QRPs) in quantitative psychology through an iterative, community-consensus process informed by existing literature. By clarifying definitions and documenting potential harms, detectability, clues, and preventive measures for each QRP, we provide a foundation for improving research integrity, transparency, and the reliability of scientific findings.

This article reviews the scarcity of published replications in economics and psychology, examines why traditional journals resist publishing them, and argues that dedicated replication journals offer an essential solution by providing critical infrastructure for the self-correcting function of science.
