In the factory studied, 22% of one group of 212 hired had left by the end of the first month, 35% by the end of the second month and less than half were on the rolls by the end of the sixth month. Use of an interest inventory enabled the reduction of first‐month turnover from 22% to 7.5%; six‐month turnover could be cut from 54% to 31%.

It is particularly worth noting that the scoring weights which actually distinguished the early quits from the continuing workers were radically different from those which would have been set on the basis of “informed judg
