In effect, Walden Two operates using a flexible design, by continually testing the most successful, evidence-based strategies in order to organize the community. Frazier argues that Walden Two thus avoids the way that most societies collapse or grow dysfunctional: by remaining dogmatically rigid in their politics and social structure. He verifies Walden Two's success by pointing to its members' overall sense of happiness and freedom—thanks in part to a program of "behavioral engineering" begun at birth. Despite these behavior-guiding procedures during childhood, the adults of Walden Two indeed appear to be legitimately peaceful, productive, and happy people; they also appear to govern the course of their own lives.
