Two-person teams took an average of just 36 minutes to assemble 50 Lego pieces into a human figure, a task that required 52 minutes for four-person teams, according to an experiment by Bradley R.

Increasing a team's size can hamper coordination, diminish members' motivation, and increase conflict, the researchers say.
