Wisdom of the crowd

Definition

Wisdom of the crowd refers to the collective intelligence that emerges from the aggregation of individual judgments, opinions, or decisions. This concept suggests that a group can often make better decisions than a single expert, as diverse perspectives and knowledge can lead to more accurate outcomes. The effectiveness of this phenomenon relies on the diversity of the crowd, the independence of individual opinions, and the ability to aggregate their responses.
