Some details of the study methodology, especially concerning sampling methods and demographics of study participants, remain undefined in Landmark Education's "full report" on it.

The New Framework Group
By 1982, Yankelovich had grown concerned that many of the postwar policies which had more or less succeeded between 1945-1980 were badly in need of rethinking. With Congressman Les Aspin, Yankelovich chaired The New Framework Group, which brought together prominent men and women in a variety of fields, to discuss fruitful areas of reform. They created four subgroups: in economic policy, foreign affairs, social policy, and the role of government.
