Article on Effectivenss of Open Dissent in Organisations

Effective organisations are nourished by an internal culture of open dissent, while pressure to conform is damaging. Take the Columbia Space Shuttle disaster as an example: the report into the accident cites the lack of such a culture as the major cause. Cass Sustein, in his (I checked, he is a guy) Los Angeles Times article, takes this example as a starting point for a brief look at this issue, in which he further illustrates his point with examples involving Enron, judges and private investment clubs.
