Sean K. Murphy from Simon Fraser University sent a very complimentary email on the Groupthink Revisited paper. Thanks, Sean.
He also pointed me to a paper by Clay Shirky who some of you might know:
*A Group is its Own Worst Enemy*
In the paper, Clay makes good use of Bion's *Experiences in Groups*. The paper can be downloaded from;
