Always show the number of user ratings in list items

Throughout multiple rounds of Baymard’s large-scale testing, it’s clear that user ratings and reviews are critical to users’ purchasing decisions (e.g., see our article on responding to negative reviews or designing the ratings distribution summary).
However, it was also observed in testing that only displaying user ratings averages — the “star” average — in list items was not enough.
Indeed, without knowledge of how many users had rated products, a substantial number of participants distrusted the validity of user ratings averages.
