"The bulk of statistical criticism is of the hit-and-run variety – the critic points out some real or fancied flaw and supposes that his job is done. Indeed, some critics appear to labor under the misconception that if some flaw can be found in a study, this automatically in validates the author’s conclusions. Since the critic makes no attempt to develop a tenable counterhypothesis, his performance is on a par with that of a proponent who glances at his data and then jumps to his conclusion."
