Cass R. Sunstein on Democracy - Dictionary of Arguments
Democracy/Discussion/Committees/Communication/Deliberation/Psychology/Sunstein: it is controversial today whether discussion always leads to better decisions. (1)
It can happen that group members put pressure on others, which can lead to extremism or unanimity with regard to false information.
Group Thinking/Irving L. Janis/Sunstein: Jani's thesis: Groups can easily lead to uniformity and dangerous self-censorship by not correctly combining information and extending disagreement to a wider area. (2)
The main problem is that groups usually do not use the knowledge that their individual members have. This became particularly clear in a 2004 Senate report on the CIA. (3) After this there was group pressure, neglect of alternatives, selective perception and suppression of criticism. (4)
Solution/Sunstein: in order to shed light on the weaknesses of communication in groups, we need to examine the consequences of two weaknesses:
a) information influences that lead to non-disclosure of divergent information by group members.
The pattern in these cases is: How can so many people be wrong?
b) Social pressure: you do not want to spoil it with superiors.
