You could come up with an algorithm that instead of showing an average of 5 stars, biases the weighting towards people who rate things in a similar way to you.

You could come up with an algorithm that instead of showing an average of 5 stars, biases the weighting towards people who rate things in a similar way to you. We all have an internal set of assumptions about what a 5 star rating system means to us; this is a case where the filter bubble leads to better understanding. People would then see the ratings they expected rather than a mix of different methodologies averaged?
