First off excuse my ignorance of statistics ... but I'm trying to get better. So here's the stupid question?

So why is it bad to threshold raw p-values? I always threshold FDR just because it makes more sense to my simplistic viewpoint.

Off topic, agree, editors should have a list of stuff that just is not allowed. My personal favorites, quantitating western blots with no standard curve and ChIPs were IgG is the only negative control.
