I think the case of the 4:1 product at about half the cost but wall less positive reviews also calls in to question how effective Amazon's presentation algorithms are. A logical solution would be to have their ranked search cherry pick the highest (number and score) reviewed results for focus within a given price category. However I normally hate their ranked search since it's results normally don't seem relevant to my needs. Thus I tend to manually do that by sorting by price and then eye-ball filtering for quality/look in picture (yeah, I used that as a quick filter for poor quality). It would be nice if I could instead directly assign weights to different type of metrics and have Amazon present the list according to my score based on perceived importance. They could use the data from that and actual buying outcomes to tune their default filter (that one might better balance high scores on multiple metrics being sorted to the top of the list).
