Statistics Seminars: "Web-enabled Strategic GDSS, e-Democracy and Arrows Theorem: A Bayesian Perspective"
6 May 2005 00:00 in CM107"The advent of web-technologies has brought the possibility of supporting geographically and temporally dispersed decision making. However, while the technology is available, it is not clear that valid methodologies for its use are. Many approaches to supporting decision making are driven by the perspective of a single decision maker. Yet there are many reasons including Arrows Impossibility Theorem, to expect that the extension of these individualistic theories to a group context will be fraught with difficulty. This paper explores these issues and considers the way forward for the design and use of distributed or web-enabled group strategic decision support and for a more substantive approach to participative e-democracy. It suggests that valid web-enabled group decision support and e-democracy will need address communication and explanation within the human-computer interface much more than has occurred to date.
Keywords: Arrows impossibility theorem; the Bayesian paradigm; group decision support systems (GDSS); e-democracy; procedural and substantive democracy; societal decisions. "
