Assembly Bonus Effect

Social Biases and Group Effects

The assembly bonus effect, first proposed in 1964, is the tendency for a group's performance on a task to exceed what its most capable member could achieve alone, or what would be predicted simply by combining each member's individual contributions. Research treats the effect as both task-specific and a broader expression of collective intelligence, in which groups draw on synergy and the diversity of members' perspectives to reach a level of performance beyond what any individual could reach working alone.
