The use of performance-enhancing drugs has certainly come to the forefront of athletics. This issue involves not only athletes but coaches and physicians as well. Our society's obsession with obtaining "the edge" is reflected in the athlete's perception that the end justifies the means.

AJR:194, May 2010 that aggregates are more reliable when the individuals who make them up are both diverse and independent. What interests us here, however, is not so much the wisdom of crowds but rather how to improve the performance of small groups of people who are working together to make decisions.
