When it comes to qualitative decisions moderately-sized ‘crowds,’ around five to seven members, are likely to outperform larger ones.
Researchers mathematically modeled group accuracy under different group sizes and combinations of task difficulties. They found that in situations similar to a real world expert panel, where group members encounter a combination of mostly easy tasks peppered with more difficult ones, small groups proved more accurate than larger ones.
