I came across this repo lately from the very talented @mattt and thought it would be a useful addition to recommendable. From his page

Sorting by positive vs. negative % alone gives undue advantage to items with fewer ratings, whereas sorting by total number of positive ratings makes it difficult for new items to break into the top.

Fortunately, there is a correct solution: use the lower bound of Wilson score confidence interval for a Bernoulli parameter.

Along with more info and a link to the math behind it.
