Is there anyone else who thinks the "5 star" rating is somewhat flawed, or is it just me?

I think, the problem is that the scale is all on the positive side, but people are trying to use it to give negative rating. So naturally they readjust the scale, so that it has both, positive and negative sides, by "shifting" the zero of the scale. Now, where exactly does it go? Will 3 become 0, or is it 2 for some people, or maybe 4?

I know it's way too late in the game, but why can't the rating system be just a simple "good", "bad", "it's ok", or maybe even: :-(, :-|, :-)




I am not enamoured with the "5 star" system, but I have to say that I like it more than the standard 5-choice system that explicitly labels the choices as positive or negative: Strongly Disagree, Disagree, No Opinion, Agree, Strongly Agree

I despise that sort of system. None of the choices ever seem to be appropriate for what I think or feel.

Star systems avoid inspiring this frustration in me by giving me the freedom to imagine labels that I think fit how I feel or think.

And in statistical circles, this is called survey bias (rating bias).

If you think a 4 is "awesome", and another person thinks that it means "pretty good", and this effect is widespread, it will result in a biased survey that is difficult to interpret.


When Netflix had their contest to improve recommendations, one of the common first-pass techniques on the forums was to zero-adjust the ratings for each user. It's hard to imagine that a big-data company of Google's size couldn't do this already, although who knows if they are.


Whatever netflix did it doesn't seem to have worked.

I noticed a while ago that literally 100% of netflix content (based on around ~50 things I checked on) has between 3 and 4 stars.

This makes ratings completely useless.


Croatian school system uses grades 1 to 5. 1 is fail, 2 is pass, 3 is good, 4 is very good and 5 is excellent. Teachers sometime also add a minus or plus in front of the grade, e.g. -5 is almost excellent and 4+ is a bit better than very good.
