The term "wisdom of crowds" is well-recognized at least since the publication of James Surowiecki's book with the same title. It refers to the phenomenon that the aggregated estimates of many different individuals often constitute a surprisingly accurate predictor of the unknown quantity or quality to be estimated. In a recent paper by platform researcher Stefan Palan, co-authored with Jürgen Huber and Larissa Senninger from the University of Innsbruck, the authors study which aggregation mechanism performs best. They compare simple means and medians and more complex, market-based mechanisms. They find that the continuous double auction outperforms all other mechanisms in terms of prediction accuracy.
