I agree, but unfortunately that doesn't address the complaint. If surveys are in fact whacked out by bias (idk), then we won't get certain kinds of meaningful data from those surveys. It's tough for the surveyors, but that doesn't overcome the objection. I think in some fields this may be more obvious. If particles are too big for the LHC to find them, then we won't get meaningful data about those particles from those experiments. We can point out that we built a ridiculously, unbelievably huge collider and what do people expect? It's a valid point, but too bad for us.
