 Peter Lawrence was able to add greater historical depth to the study of cargo cults, and observed the striking continuity in the indigenous value systems from pre-cult times to the time of his study.Kenelm Burridge, in contrast, placed more emphasis on cultural change, and on the use of memories of myths to comprehend new realities, including the "secret" of European material possessions.His emphasis on cultural change follows from Worsley's argument on the effects of capitalism; Burridge points out these movements were more common in coastal areas which faced greater intrusions from European colonizers.
