S ummary . Comparison is made between the very high proportion of adolescents found by Somerville to be formal operational thinkers, and the much lower proportion found by Lovell. Evidence about the representativeness of Somerville's sample is analysed suggesting that it is comparable with that of an average English selective school. When allowance is made for the difference in populations the results are shown to be not in conflict.
