You could probably get around this by A) labelling 1-2 review items with "needs more reviews" message Or B) not giving an aggregate review score for low review items. Actually replacing the review star bar with "needs more reviews". Then when the user goes from the listing page to the detail page, you can show the reviews next to a message saying "this item only has a few reviews, so we can't be sure they're accurate until more people chime in"
