President paragraphs

A collection of 220 paragraphs of graded value about U.S. presidents is given. The collection includes 16 paragraphs about each of nine presidents and 8 paragraphs about each of eight presidents. For each president, the paragraphs have one of four rough values for judgments of statesmanship, H, M⁺, M^-, and L. These paragraphs have proved useful in experimental applications of integration theory to attitude change. Other advantages of U.S. history as a source of issues and material for research on attitudes are also pointed out.
