Quando é que mais informação é contraproducente?

Qual é a melhor solução organizativa para sustentar um processo colectivo de investigação e detecção de soluções para problemas de todo o tipo? Esta notícia The downside of a good idea dá conta dos resultados da investigação para responder a essa pergunta. Excerto:

"In the "fully connected" group, everyone's work was completely accessible to everyone else -- much like a tight-knit family or small town. In the "locally connected" group, participants primarily were aware of what their neighbors, or the people on either side, were doing. In the "small world" group, participants also were primarily aware of what their neighbors were doing, but they also had a few distant connections that let them send or retrieve good ideas from outside of their neighborhood.

Goldstone found that the fully connected groups performed the best when solving simple problems. Small world groups, however, performed better on more difficult problems. For these problems, the truism "The more information, the better" is not valid.

"The small world network preserves diversity," Goldstone said. "One clique could be coming up with one answer, another clique could be coming up with another. As a result, the group as a whole is searching the problem space more effectively. For hard problems, connecting people by small world networks offers a good compromise between having members explore a variety of innovations, while still quickly disseminating promising innovations throughout the group.
