Humans vs XG on Facebook Review 2019

Humans vs XG is a game we play on Facebook where the human team votes for the move of the day in a continuous money game. In the last 12 months we have played 45 games and the human team is leading XG 54 - 36, but what is more impressive is the humans' PR of 1.74 with just 5 blunders and other 23 errors out of 360 decisions. This low error rate is in large part due to the voting system which where the majority tend to find the best move. The main thing for me though, is that it gives us a great learning platform with with a purpose, i.e., to beat XG. Reading and taking part in the discussions are a Great way to learn and I am very pleased that we have some world class players contributing most days. The group has continued to grow over the last 12 months to more than 550 members.

That's amazing. Has this been tried with chess?

Re: Humans vs XG on Facebook Review 2019

There's an excellent book on this phenomenon, "The Wisdom of Crowds". The general idea is that if you ask a question to a large group about something that the group has a general knowledge of, then average the answers, you'll get an answer that's much closer to the truth than the opinion of any particular expert.

Typical example: you're at a country fair and there's a prize bull that will be awarded to the person that comes closest to guessing the bull's weight. The contestants are all farmers who know something about bulls. The guesses will be all over the place, but the average of the guesses will be very close to the bull's actual weight.

Seems to me that backgammon would be a very good arena for exploiting this phenomenon. I think chess would be less so.
