Gotcha - then I think you are misreading my 2nd post - directing consumers away from psudo-scam products is "reversing" the understanding. Not assuming everyone wants one perfect product, but realizing that almost everyone wants to avoid known bad products. A bare bones $100 air fryer is good value. > I really don't know where you think I implied that When you said "What you perceive to be "good value" might be "over…
It's possible we're not on the same page on what you meant, but after your clarifying, it still requires defining what a "bad product" is, and that's not as easy as it feels like you're suggesting. A cheap product can be both good value and a bad product, depending on the type of product/intended use/customer expectations/etc. But it's up to the customer to decide that.

Ok, let's look at this example to refocus. I agree with you that OP is mistaken in their analysis - that you can't jump from the most popular item to knowing that item is best for everyone. But I think we have switched onto talking about other things the vendor could do.
Both Amazon and the grocery store both keep records on why people return things (and general complaints) and they would be able to track items that people dislike. Amazon already warns you when an item is returned often, for instance. So I'm saying that Amazon can know when someone buys ads for a product that has higher than normal returns and they may have a responsibility there. In general retailers can be held liable for selling defective products even if people want to buy them so I think there's a framework for warning consumers.
