- p-Hacking and False Discovery in A/B Tests -- Experimenters indeed p-hack, especially for positive effects. Specifically, about 57% of experimenters p-hack when the experiment reaches 90% confidence. Furthermore, approximately 70% of the effects are truly null, and p-hacking increases the false discovery rate (FDR) from 33% to 42% among experiments p-hacked at 90% confidence. Assuming that false discoveries cause experimenters to stop exploring for more effective treatments, we estimate the expected cost of a false discovery to be a loss of 1.95% in lift, which corresponds to the 76th percentile of observed lifts. But it feels good to optimize your product with data, and that's what counts.
