It doesn't matter? Regardless of how people distribute their scores, as long as there is some overall correlation to quality, then there would be a cutoff at some point (as long as Uber decides to remove drivers below a certain cutoff). It just so happens that based on the aggregate data that they see, it is 4.6. It could be any arbitrary number, and anyone's personal anecdote on how they rate drivers doesn't really matter in the grand scheme of things.
- hn_throwaway_99 7y agoIt absolutely does matter, because it leads to "grade inflation" - people change their rating because, like the parent comment, they know that anything besides a 5 is voting to get the driver fired. Indeed, I'm only willing to give someone below a 5-star rating if I think I got really horrible service.
- ypzhang2 7y agoBut all that does is move up the threshold. Feels like you and the parent comment are assuming the threshold stays fixed. That is most likely not the case. Uber is setting the stars threshold at some arbitrary number to achieve some quality goal based on their internal data. Its not like Uber can't see the distribution of stars. Based on how people vote, they pick a cutoff in order to achieve their quality goals. If people change the way they are rating drivers, that cutoff will change as well.
