You could be the worlds best expert on X but a highschool student with some basic statistics could easily invalidate the experts conclusions. And the highschool student would be right, and the expert would be wrong. It doesn't matter how much of an expert you are if your conclusions are wrong because you don't know statistics. If anything, an "expert" like that is actually a complete fraud.
