We constantly make decisions based on perceptual experiences. For example, a referee at a soccer match trusts his eyes to judge whether the ball crossed the goal line. Sometimes, the resulting decisions are false, with devastating consequences for one team. If two referees watching the same match made joint decisions, would the result overall be more precise? On page 1081 of this issue, Bahrami et al. (1) find that joint decisions are better than those made individually, but only under certain conditions.
