Something that I've noticed over the last year is that there is sometimes a disconnect between the overall rating of a product, and a summation of the ratings given by the individual reviews. Like a product with have 4-stars, but the majority of reviews seem to be 1-star.
While returns are still pretty easy to do on the buyer side, I used to trust amazon a lot more than I do now, and am considering dropping my prime subscription.
- obsurveyor 10y agoPoster child of the rotten ratings right here: https://www.amazon.com/gp/product/B01B6ZHV7C?th=1 https://www.amazon.com/gp/product/B01B6ZHV7C?th=1 (rated 4 stars but 87% of reviews are 1 star)
- thearn4 10y agoOh wow, that is absolutely blatant rating inflation!
- PirateDave 10y agoI just looked into why that is the case and if you hover over the little dropdown carrot for the "3.8 out of 5" you see this: Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases. So a product would just need a small percentage of 5 star reviews in the beginning of the review period.
