Quizplus · Accepted Answer

Studies have found that making decisions by averaging individual judgments can be efficient and accurate, leading to the "wisdom of crowd" effect. This has been observed in various contexts, from guessing the weight of an ox to predicting market trends. There is no specific maximum number of group members mentioned, and the effectiveness of the group depends on the task at hand. While discussion among group members can help improve accuracy, it is not always necessary for the "wisdom of crowd" effect to occur.
