According to James Surowiecki in the book “The Wisdom of Crowds:” When “Groups” are involved in making a decision they normally have better than “house odds,” which is 70% of getting it right without having 100% of the facts.

However, without the facts being available to any human it lowers the odds to a little over the 50-50 point.
