Earlier papers have described researches showing that i.q . increments in adolescent and young adult persons certified as feebleminded occur not infrequently, cannot be explained as artefacts, and appear to be linked with early very adverse environmental experiences. The present three studies indicate that i.q . increments can be large over long periods of time, are correlated with changes in social adjustment, but cannot be shown to be induced by special environmental stimulation; in the present age range and type of subject, they tend to occur in any reasonable environment. Results imply that a necessarily poor outcome cannot be predicted for children with i.q .'s in the 50's, 60's or 70's if they also come from very adverse conditions. Test reliability, statistical regression, and a review of some relevant literature are discussed; theoretical problems concerning intellectual development are presented; and attention is directed to individual differences in susceptibility to environmental damage and to the whole problem of human resilience.
