. Warfield left a typed note after this title, on a list of box contents packed for moving which he compiled in 2008: "Spreadthink: - One of the most important papers I ever published" This paper is in Warfield's collected papers volume titled: Education Papers by Warfield. Material in this paper was first presented in a talk given in Pittsburgh, September 1994, at Annual Meeting of Association of Integrative Studies. It was published in Systems Research in 1995. Annotation: The author's careful data on individual reactions to group problems has revealed the phenomenon which he calls Spreadthink, e.g, there exists a consistent lack of commonality of viewpoint, no matter what the group, no matter what the problem. The disparity in attitudes among individuals is so great as to produce ineffective group decision making unless further education and understanding takes place between group members.
