Sure. Anyone with the most basic stats knowledge knows that if you dig long enough you'll find random correlations. That's solved by demanding evidence be repeatable rather than requiring the evidence fit into a nice theory.
But asking for a theory can help the situation, that was my point. Of course demanding a theory even in the face of repeated findings isn't helpful, but encouraging a theory, or giving "bonus points" for a theory is, I think, a perfectly reasonable thing to do.
