WebGenerally it is bad science to adjust your decision rule for significance after peaking at the results. However, if you're doing a ton of hypothesis tests you'll probably want to adjust for that - the overall result of that will generally be to lower your p -value threshold for significance. How many are you doing? WebNov 1, 2024 · Lowering the P value threshold to 0.005 will likely increase the number of true effects that are reported in the literature. Lowering the P value threshold was not the only proposal for improving statistical significance Ioannidis mentions.
