"WebSep 1, 2024 · When performing a two-sided permutation test, we calculate both one-sided P -values, multiply the smaller by 2, and if necessary round down to 1.0. Two-sided P -values are the default in statistical practice: you should perform a two-sided test unless there is a clear reason to pick a one-sided alternative hypothesis. " - Spin permutation tests
