Cornflakes Experiment

Were you asked to guess the number of cornflakes in a jar, and are you curious how many were in there, and if peoples average guess is indeed close to being currect?

The actual number of cornflakes was 1146 and the average guess was a remarkable 1149,7. Out of 270 guesses no one came closer to the correct answer. 1150 was the best individual guess but guesses varied widely- some where in the hundreds and some where in the thousands.

Judging by our experiment the phenomenon of the wisdom of the crowd truly has merit. Aristotle compared it to a potluck dinner where everyone brings a different dish and the result is surprisingly good. We will do the experiment again next year as we always do as a Thales Day ritual. We will see if our result will be as impressive. If you like the initiative behind Thales Day we welcome you to send us your email adresse and/or like us on Facebook and get updates on future Thales Day events.
