Sam Echols was injured when he was struck in a crosswalk by a car driven by Ceila Jones. Echols' lawyer suspects that Ms. Jones was not wearing her contact lenses at the time of the accident as she is required to do by law. After Echols' lawyer files suit, how can she find out whether Ms. Jones was wearing her contact lenses?

Recall that in one condition of the experiment conducted by stasser and titus (1985) about student council president candidates, all group members had access to the same information, and that in another condition, members had unique information that other group members didn't know. in the second (unshared information) condition, the group made a worse decision than in the first (shared information) condition. this occurred because groups seldom can agree on who is most expert. focus discussion on the information that all members know. often ignore dissenting opinions. avoid differences of opinion, given conformity pressures.
