I heard a radio talk show host talk about the absurdity of having a rating system with too many choices. He had recently completed a product survey where it asked him to rate his satisfaction on a scale of 1 to 16. Does a person really distinguish that many degrees of happiness with a TV, for example? How do you distinguish between say an 11 and a 12?
Ironically, later in the program this same host did a movie review and rated it three and three-quarter stars out of four, apparently not realizing that he was giving the movie a 16 on a scale of 0 to 17.
