Detecting p-hacking
WebJan 1, 2024 · Simonsohn, Nelson, and Simmons (2014) have suggested a novel test to detect p-hacking in research, that is, when researchers report excessive rates of "significant effects" that are truly false ... WebMar 24, 2024 · We theoretically analyze the problem of testing for p -hacking based on distributions of p -values across multiple studies. We provide general results for when such distributions have testable restrictions (are non-increasing) under the null of no p -hacking. We find novel additional testable restrictions for p -values based on t -tests.
