I have been wondering about this for a bit and forgive my ignorance. Consider we loath the NHST approach, but value the information the p-value gives. I consider the we have a "perfect" experiment. I apply any statistical test, and have n predictors/variables (no idea why a "perfect" study would have n predictor variables, humor me). I also have the effect-size and intervals. Based on a small pilot study and literature I know what a "small" or "large" effect-size is, what I deem reasonable and what kind of variability I can expect. If I consider the p-value as a merit on its own giving me useful information on the variability and consistency in my data. When correcting for multiple comparisons you lose the information the p-value gives. Considering I do not suggest p < .05 as "significant" or any other stark boundary. What rationale is there to correct the p-value for multiple comparison given I do not apply the NHST approach, but describe the observations in the data related to my question(s)?

Thank you in advance
