Wisdom of the crowd

Warning: This exhibit, actually, can be in either the Dice or Digits section since the idea is to count how many objects are in the plexiglass containers but in fact it is difficult to count them so they are estimated.

In the Numbed by numbers exhibit, two exhibits had been created, one with a glass jar filled with candy, in which people were asked to make an estimate of the candy by entering the estimate into a tablet; in this case, the exhibit was paired with a contest in which prizes were awarded to those who came closest.

A second exhibit, placed at the beginning of the exhibit, involved 4 plexiglass cylinders with different objects inside (glasses, straws, caps, and colored spheres), again asked to enter the estimate into a tablet (the pages and files for editing them can be found attached here).

How many candies are in the glass jar? Mathematics tells us that we find the best estimate by appealing to what scholars call “The Intelligence of the Crowd” (or the wisdom of the crowd), a sociological theory that a collection of people can make any estimate better than experts can.
