Ever wondered if you should go for the product that has 10 5 star reviews, or the one that has 50 4 stars? Well, 3Blue1Brown did a video on this which gave a really simple answer to this problem. Basically, pretend as if there is one more positive review, and one more negative review, and then calculate the ratio. The resulting value can easily be compared amongst different products. And it takes into account the amount of reviews, not just the score of them.
This easy solution inspired me to write an addon that shows these values next to review ratings.
Initially this only supports Google Maps Places, as I was in the process of finding a good hairdresser when I encountered this problem.
But in the future I might add Amazon reviews and the like.
