SUMMARY:CPG: Marlon Twyman (USC\, Communication & Computer Science)
DESCRIPTION:Title: Metawisdom of the Crowd: How Choice Within Aided Decision Making Can Make Crowd Wisdom Robust \n  \nAbstract: Quality information can improve individual judgments but make group decisions less accurate; if individuals attend to the same information\, the predictive diversity that underlies crowd wisdom may be lost. We explore this tension within the context of decision support systems that provide the choice of decision aids and before then primary judgments. We argue that whenever a set of decision aids induce diverse errors\, this structure leads to higher group accuracy because aid choice will exhibit predictive diversity itself. In two experiments—the prediction of inflation (N=1907\, pre-registered) and a tightly controlled bean-count estimation task (N=1198)—we find strong evidence for this.

SUMMARY:Department Speaker Series: Scott Page (University of Michigan\, Business\, Political Science\, Complex Systems\, and Economics)
DESCRIPTION:Speaker: Scott E. Page (University of Michigan\, Santa Fe Institute). (website) \nTitle: Organizations and Cultural Coherence \nAbstract: I construct a mathematical framework to elucidate and analyze the interdependence between structural features of an organization and some of its cultural attributes.  By the structure of an organization\, I mean whether individual actions are assigned hierarchically\, agreed upon through a more equal democratic process\, or encouraged through incentives.  By culture\, I will focus on standard measurable features such as tightness\, individualism\, trust\, risk taking\, and uncertainty avoidance.  I show that congruence – the alignment of organization structure and culture – though an often articulated organizational goal does not\, except in rare cases\, imply efficiency.   The creation of a healthy\, constructive culture and not congruence should therefore be the goal of organizations. \n
