WebApr 21, 2024 · Simonsohn et al. (2014) suggested that it is possible to detect the use of dumb p-hacking methods by means of p-curve plots. Repeated sampling and the use of covariates produce markedly left-skewed (monotonic decreasing) p-curves. Schimmack (2024) noted that left-skewed p-curves are actually very rare. Figure 1 shows the p-curve …
