Surprisingly popular
The surprisingly popular answer is a wisdom of the crowd technique that taps into the expert minority opinion within a crowd. For a given question, a group is asked both "What do you think the right answer is?" and "What do you think the popular answer will be?" The answer that maximizes the average difference between the "right" answer and the "popular" answer is the "surprisingly popular" answer. The term "surprisingly popular" was coined in a 2017 paper published in Nature entitled "A solution to the single-question crowd wisdom problem", which outlined the technique.
