but they miss the central point of ratings systems: to manage risk.
-
There are two main sources of risk that are important for rating and reputation systems: asymmetric information and uncertainty.

Movies, books, and wine are examples of experience goods, which we need to experience before we know their true value.
-
Good rating systems also don’t inappropriately “flatten” the information that they collect into a single number. Products and services can have many characteristics, and not being clear on what characteristics are being rated, or inappropriately lumping all aspects into a single rating, is misleading and makes the rating meaningless.
-
When rating experiences, what is being rated is relatively clear. Did you enjoy the experience of consuming this good or not?
-
The point here is that rating systems need to be appropriate for the goods or services that are being rated.

Howard RheingoldSo, when we think about rating and reputation systems, the first question to ask is not, “Am I using stars, bananas, or chili peppers?” but, “what risk is being managed?”
