I would say it is. By not being hypothesis driven, you are producing too many degrees of freedom by de facto testing every comparison. This is a huge problem

I would say it is. By not being hypothesis driven, you are producing too many degrees of freedom by de facto testing every comparison. This is a huge problem in science too. I have regularly been told to just see what happens and come up with hypotheses after, or others have been unable to say what their hypotheses actually are. Scientists seem less and less likely to be trained in statistics, and in the scientific process. Technical knowledge is important, but understanding of the scientific process is much more important.
