Derren Brown correctly predicted the winning lottery numbers and put the feat down to a complex mathematical formula. According to the illusionist and hypnotist, he gathered 24 people who wrote down their predictions after studying last year’s numbers. All guesses were then averaged - added up and divided by 24. The “wisdom of the crowd” theory suggests that a large group of people making average guesses will get the correct figure as an average of all of their attempts.
Sounds pretty ridiculous to me, but hey - he did it. Many people still say it was a trick, that he got the numbers before they were announced somehow, even though the entire thing was live. I’m looking forward to finding out what actually happened. I do want to read more about this “wisdom of the crowd” theory.
