That will be tue only if a 'real' survey shows a very different / contradictory result form the phantom survey, which I expect is NOT the case.
Actually, there have been many other surveys on this point, and they all reached results that contradict Lott. (Those other surveys include some done by Gary Kleck, the preeminent and very pro-gun criminologist at Florida State University.) The discrepancy between those surveys and Lott's survey are the very reason that people started wondering about the legitimacy of Lott's survey in the first place.
