meta-analysis A system of statistically analyzing very large numbers of already-published experiments each of which may not, in itself, be significant, and extracting from them information to be looked at with a view to obtaining validation of the sought-after effect. Only if an overall application of faulty procedures has been applied, or experimental results have been generally misreported, could properly applied meta-analytic procedures falsely indicate positive results. This procedure is gaining popularity among parapsychologists, who seem to always have miserable luck with simple, directly applied scientific methods and analysis of results.
