Hutch CarpenterWhere would we be without rating and reputation systems these days? Take them away, and we wouldn’t know who to trust on eBay, what movies to pick on Netflix, or what books to buy on Amazon. Reputation systems (essentially a rating system for people) also help guide us through the labyrinth of individuals who make up our social web. Is he or she worthwhile to spend my time on? For pity’s sake, please don’t check out our reputation points before deciding whether to read this article.
Rating and reputation systems have become standard tools in our design toolbox. But sometimes they are not well-understood. A recent post at the IxDA forum showed confusion about how and when to use rating systems. Much of the conversation was about whether to use stars or some other iconography. These can be important questions, but they miss the central point of ratings systems: to manage risk.
So, 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?” -

The point here is that rating systems need to be appropriate for the goods or services that are being rated. A rating system for books cannot easily be applied to a rating system for routers, since the products are so entirely different in how we experience them. What aspects we rate need to be carefully selected, and based on the characteristics of the product or service being rated.

While designing a good reputation system is hard, it’s not impossible. There are five key things to keep in mind when designing a reputation system:
-
1. List the behaviors you want to encourage and those that you want to discourage
-
2. Be transparent
-
Any clarity that is added to a reputation system will make your users happy, and it will make them more likely to behave in the manner you desire.
-
3. Keep your reputation system flexible
-
4. Avoid negative reputations
-
5. Reflect reality

- Are they honest and authentic?
- Are they like you in a way that is meaningful?
- Are they qualified to adequately rate the good or service in question?
