| Abstract: | Berk criticizes meta-analysis on a host of statistical grounds. The criticisms are thoughtful, and may even seem compelling on first read. However, his criticisms are really a special case of the kinds of criticisms that can be leveled at all scientific endeavor. Science is rife with assumptions of greater or lesser plausibility, no more so in meta-analysis than in primary research. We trust in those assumptions only temporarily and heuristically. The answer is not to abandon ship, but rather to work to improve the endeavor at the margin, hoping that science is self-correcting in the long-run, and that our answers are not too far off despite the weaknesses of the enterprise. |
