They procrastinate, calling for further information. And they become committed to bad decisions, to save face or to protect themselves against criticism…

In a recent simulation, Dr. Beth Dietz-Uhler, a psychologist at Miami University of Ohio, analyzed the behavior of small groups of three or more people acting as city council members, creating a park on land donated by a wealthy resident.
