The wisdom of crowds is a well known principle, used in engineering to overcome something that is extremely difficult to measure (noisy data for instance), considering only one single measurement would be very dangerous, since it might be extremely imprecise. However, if you measure 1000 times and take the average, the errors cancel out and you have a pretty accurate measurement :)
