The problem is that the software generally filters first - e.g. "show me the 'best of'" or "sort by top rated". If you're looking at a selection of hundreds of items, I don't know that your statement holds.
In a nutshell, the scalar fallacy is the false but pervasive assumption that real-world things (hotels, sandwiches, people, mutual funds, chemo drugs, whatever) have some single-dimension ordering of "goodness".
When you project a multi-dimensional space down to one dimension, you are involving a lot of context and preferences in the act of projecting. Just sayin'.
