The Undecim Rating System (Undecim) is an eleven point rating system that goes from -5 to 5. It was created because I have always felt that traditional rating systems have not accurately conveyed what is good, and what isn’t at a glance. At its simplest, things with a rating of 0 are of “average” quality, anything above that is the degree of recommendation, and anything below is the degree or warning against it.

The scale itself does have a finer level of detail, so I’ll go into that now:

-5. Avoid at all costs, it will make you die inside.
-4. Normal people should avoid, but its ok for the already mentally damaged.
-3. Don’t waste your time on it, and don’t tell me about it, I don’t want to hear it.
-2. Subpar, but some people might like it
-1. Recommended pass, but many people will still like it
0. Average for medium
1. Slight recommendation, but many people may not like it
2. Above average, most people should like it
3. Pretty good / cult classic
4. Really good, representative of excellence in the medium
5. Basically, 4 with lasting appeal. Avoid at your own peril

    I really dig this idea. What I really like is that the definite divide between enjoyable and un-enjoyable basically combines the Like or Dislike(or thumbs down vs. thumbs up) binary rating with the less arbitrary and more adjustable 0-5 or 0-10 numeric rating system. Best of both worlds. With a good color scheme setting apart the negative side and positive side, and a minimalist icon set for each number packaged into an easily embeddable system, this might be able to get rid of the boring old zerotens.



    How about an additional rating, essentially NULL. Something that could be interpreted as “this rating system does not apply” or even “I considered rating but decided against it”.

    I wish more surveys had that sort of response. In particular I’d like to see the typical “approve/disapprove/don’tknow” responses, add one that’s like “this question is unfair” or “no choice is appropriate”.

    Most surveys don’t tabulate “no response”, so people who don’t answer don’t get counted at all. And many surveys are configured as “have you stopped beating your wife” or other “leading” questions that need to have a “WTF” response.



    Great idea sir/ma’am. Have you considered creating a library of books and rating them with said system? Throw in a few adds and you’ll have money to pay people to read, rate, and write summary’s about each book!
