Teams got the hiring decision right 15 percent of the time when the newcomer held the information the group needed, and 28.7 percent of the time when an original member held it — and the originals had been talking to each other for five minutes
A study of 370 three-person teams varied who held the unshared information the group needed. Teams were less likely to reach the correct decision when the newcomer held it than when one of the originals did. A false status boost did not reliably change that, and the whole thing happened in a text chatroom rather than an office.
