Spreadthink is a kind of conceptual pathology of groups unable to reach any "genuine consensus, or even majority view toward component aspects of a complex issue". A neologism coined by systems researcher and mathematical cybernetician John N. Warfield,〔(Who is who in collective intelligence by John Warfield )〕〔John Warfield (2006). ''An Introduction to Systems Sciences''. World Scientific, Singapore〕 describing ineffective thinking in groups. He states that this collective condition is generally neither recognized nor usually compensated for. Spreadthink reflects the fact that any time a group meets to work together on a complex issue using ordinary and familiar group processes, the individuals in the group will not agree on what are the most important sub-issues, and in general will not have a majority view on the merits of any of the many sub-issues.〔Warfield, JN (1995). ''Spreadthink: Explaining ineffective groups'', Systems Research and Behavioral Science, Volume 12, (1), 5–14, Article first published online: 29 JAN 2007, 〕 In contrast to Groupthink, Spreadthink is a quantifiable psychosocial phenomenon 〔Warfield, JN, and Carol Teigen (1993). ''Groupthink, Clanthink, Spreadthink, and Linkthink: Decision-Making on Complex Issues in Organizations'' 4-5, 31, Institute for Advanced Study of the Integrative Sciences, George Mason University〕〔Christakis, A.N., & Bausch, K.B. Ch 25: Measuring Observer Spreadthink and Situational Complexity. In: Christakis, A.N., & Bausch, K.B. (2006). How People Harness Their Collective Wisdom and Power to Construct the Future. Greenwich, CT: Information Age Publishers〕 that occurs within diversified groups of people. It is the mode of thinking that happens when different perspectives on a truly complex problem are convened for the purposes of understanding the complex situation. The desire for expressing authentic individual voices about the situation exceeds the desire for harmony in a simplistic decision-making process. Group members try to minimize reasons for individually defecting – or leaving the group that is trying to collectively deal with the complexity. Defection results from individuals who feel that their strongly held perspectives are not included in the definition of the situation. Warfield cautions, "Facilitators who try to bring groups to a majority view or a consensus without the aid of some methodology that resolves the difficulties caused by Spreadthink may well be driving the group to Groupthink, and thus helping to arrive at a decision that lacks individual support and, usually, lacks substance." 〔Schreibman, V. and Christakis, A. (2007) ‘New agora new geometry of languaging and new technology of democracy; the structured design dialogue process’, Int. J. Applied Systemic Studies, Vol. 1, No. 1, pp.15–31.〕〔http://sunsite.utk.edu/FINS/loversofdemocracy/NewAgora.htm New agora new geometry of languaging and new technology of democracy in Lovers of Democracy page〕 Spreadthink needs to be understood in the context of the Nominal Group Technique (NGT), Interpretive Structural Modeling (ISM) and Interactive Management (IM) developed by Warfield and his team. One further outcome was the phenomenon of Erroneous Priorities Effect (EPE) 〔Dye, K. (1999). Dye’s law of requisite evolution of observations, in Christakis, A.N. and Bausch, K. (Eds.): How People Harness their Collective Wisdom and Power, Information Age Publishing, Greenwich, CT, pp.166–169.〕〔(EPE in Dialogic Design Science page )〕 outstandingly first scientifically demonstrated as a spreadthink (group) pathology by Kevin Dye〔Laouris, Y.
