Third, the aggregate trajectory outperforms more than 99% of individual trajectories. ![]() Second, this great improvement requires aggregating trajectories from different individuals (rather than trials from the same individual). First, the aggregate trajectory can be up to 5 times more accurate than the individual ones. Our results show the characteristics of the strongest examples of Wisdom of the Crowd. We asked more than 700 school students to trace five patterns shown on a touchscreen and then aggregated their individual trajectories to improve the match with the original pattern. Here we tested this effect in the context of drawing geometrical shapes, which still enacts cognitive processes but mainly involves visuomotor control. ![]() Because of its enormous social potential, this effect has been thoroughly investigated, but predominantly on tasks that involve rational thinking (such as estimating a number). Wisdom of the Crowd is the aggregation of many individual estimates to obtain a better collective one.
