Kasparov versus the World
This sort of proves that there is no such thing as "Wisdom of the Crowds". There seems to be a bit of a cult myth [1][2] about groups being able to "on average" outperform even the best individuals but that seems to be based on some rather flimsy studies whose methodology has not been published. It seems more likely that in reality, data is cherry picked, where it correlates with the "Wisdom of the Crowds" myth nit gets published, if not it gets discarded.<p>The most rigorous experiment I've seen performed, tested a group of reddit users on estimating lines in an image [3]. Some expert individuals were far more accurate than the group average.<p>[1] <a href="http://feiss.be/blog/post/169" rel="nofollow">http://feiss.be/blog/post/169</a><p>[2] <a href="https://www.cfapubs.org/doi/abs/10.2469/faj.v43.n3.50" rel="nofollow">https://www.cfapubs.org/doi/abs/10.2469/faj.v43.n3.50</a><p>[3] <a href="http://feiss.be/blog/post/169" rel="nofollow">http://feiss.be/blog/post/169</a>
