It baffles me that Amazon doesn't use their shopper's data more effectively. They could have gone with a weighted average, accounting for number of reviews, consistency of scores, etc. of the shopper in question. Instead, they want to highlight the most deceptive side of the scores, i.e. 5-star ones. Kinda feels like they don't want to end fake reviews, but prop them.
