Geoff Cumming uses simulations to demonstrate the high variability of p-values and argues for using confidence intervals instead.
I use a simulation from my ESCI software to illustrate the enormous variability in the p value, simply because of sampling variability. That's the dance of the p value. Never trust a p value--it's too unreliable! Use estimation, not NHST! Most researchers don't appreciate just how unreliable the p value is!What people say. Recommended as an excellent and intuitive visual explanation of why p-values are unreliable and how they vary across replications.
