Of course experimental design is very important in general. But VAuroch and I agree that when two designs give rise to the same likelihood function, the information that comes in from the data are equivalent. We disagree about the weight to give to the information that comes in from what the choice of experimental design tells us about the experimenter’s prior state of knowledge.
Hold on- aren’t you saying the choice of experimental rule is VERY important (i.e. double blind vs. not double blind,etc)?
If so you are agreeing with VAuroch. You have to include the details of the experiment somewhere. The data does not speak for itself.
