If a large number of judgments or rankings of a series of lifted weights, by the same subject or by different subjects are grouped, correlated with the true order, and averaged, the result will be an increase in validity. This increase is not due to the fact that the judgments were made by different people, but to the mathematical principle involved in Gordon's method of combining the data. When ten weights are used the increase in validity follows that predicted by the Brown-Spearman formula. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
