Studying more statistics is often clever. Although in this case Mr. Miller led the the most important part - if there are two numbers (like 7 and 5) in a statistical context they might be the same number. That throws a lot of people into such a tailspin that they never really recover after making the obvious mistake of thinking they are different.

The powerful heuristic for the less technically inclined is to say "well, this evidence isn't conclusive until someone who knows statistics has tried to shoot it down".
