Evan Miller argues that it's probably simplest to stick with thumbsup/thumbsdown, but not to fall into the trap of using dead-simple analysis methods like "Score = (Positive ratings) − (Negative ratings)". Instead he argues you should use the "Lower bound of Wilson score confidence interval for a Bernoulli parameter". He provides that equation and example code to calculate it (Ruby, SQL, and/or Excel). https://www.evanmiller.org/how-not-to-sort-by-average-rating.html https://www.evanmiller.org/how-not-to-sort-by-average-rating... https://news.ycombinator.com/item?id=15709405 https://news.ycombinator.com/item?id=15709405 https://www.evanmiller.org/bayesian-average-ratings.html https://www.evanmiller.org/bayesian-average-ratings.html https://www.evanmiller.org/ranking-items-with-star-ratings.html https://www.evanmiller.org/ranking-items-with-star-ratings.h... https://redditblog.com/2009/10/15/reddits-new-comment-sorting-system/ https://redditblog.com/2009/10/15/reddits-new-comment-sortin...
