So in short, this is my suggestion: Alllow us to score anime with one decimal place accuracy. (1.0)

I think it could make Myanimelist even more interesting and effective:

1) Some people like keep some anime they particularly enjoy higher than other anime of the same level, but don't feel it's justified to move it up a tier (8 -> 9) just for some weird personal preference (I feel weird about my Yuru Yuri 9 but I can't help it :p It would be in the lowest point of 9 range if I could show it)

2) An anime that's almost a masterpiece but not quite because of a couple of flaws (9.4) and something that is well written and interesting but somewhat generic and lacking in other areas that's barely above 8 point range (8.5) would both get a 9. It's a pretty significant difference that does not show at all. This would not have much of an impact on MAL rankings, but at least it would make individual lists more organized.

3) More power to give detailed ratings might make people more interested in weighting their ratings more carefully. When I said in point 2) that it would not have much of a difference, I mean weighting between that range of one point. It can have impact in one additional way if it changes the way people think about ratings even a bit. I'm not counting on it though but it could be interesting to see.
Through who already give 10 to everything you enjoy just to pump it as high as possible and make it aware to more people or consider 7 a bad score not much would change in practice. I don't personally mind that, but I've seen some voice displeasure about it.

So just some thoughts. Dunno how many scripts you would need to rewrite and if it's reasonable to carry out in practice. I'm sure you would already have done it if it was effortless but I'm just saying at least I would like to see this happen.

Nope. This has been suggested many, many times before and the answer is always the same. If we change this, somebody will just turn up later and say: "I want x.xx ratings" etc. At this point, I'd think it's more likely we revert to a 5 point scale than add decimal ratings.

What are the chances of a 5 point scale happening? That'd be cool, too.

I'll bet 20 dollars that if the system is switched to 5 points, we're going to get threads complaining about people only using 4 and 5.

5 point scale sucks, and I don't think people will start asking "how about we go to the 100ths place (8.35 for example) since it is only meant for averages anyway. I say go to a 100 pt scale so then instead of having 7.5 it will be 75 and so on. I always over rank an anime because of this. But also going anywhere past the tenths place is pretty pointless, unless you're trying to make it an 1000 pt scale (which who has that anyway).

But use should know that most animes aren't just a solid 8 or 9 anyway.

Just because this change will inevitably lead to people wanting two decimal places, does not mean the change isn't worthwhile. These requests are being ignored now just fine, so we can continue to do so in the future, but a single decimal place would be very useful.

I am very much in favour of this change.

I agree with wartjr, as I have many anime on my list (Redline, for example) that aren't nines, but definitely not eights either, and this has become one of my big pet-peeves with this site.

I support this change wholeheartedly if it's ever taken into consideration.

1-10 scale is fine without decimals. I thought about this a few days ago but overall, it would be annoying to go into that much detail rating each and every one of my Animes.

I would agree if .5 was implemented.

In my opinion, the 10-point scale is more than adequate. Most places only have a 5-point system, so we already have more granularity. If any changes WERE to be made, however, I'd suggest they don't go beyond adding a .5 (essentially a 20-point system).

Because the scale has 10 positions they all must be used :D
if not you should leave as you don't wear the Holly Crown of Connoisseur

this scale is good now - sometimes it's hard enough just to divide it between those points and adding those decimals would make it even more complicated
and please don't go back to 5 points - it would make comparison of series a bit difficult

I used to be happy just using 1-10 ratings. My tastes have changed over the years and being too exact with my ratings would have been fruitless because I can't be sure how I would rate everything if I watched them all now. My standards from years ago are not the same as they are now.

Unfortunately after accumulating about 285 ratings for H-anime in the 5-6 range and with nearly all of them having forgettable plots, I can't even remember which ones I liked the most. I tried to make a list of my favorite 50 and it was impossible to do. I gave about 23 of them 7-10 ratings and I gave about 22 of them 2-4 ratings, but everything else was a 5-6 blur of about 240 titles. If I liked it around a 4-rating or lower, I most likely wouldn't have finished the anime anyway.

I can see both sides of this issue because I've been on both sides, but in my case at least I definitely needed a more precise way to rate my H-anime. Non H-anime is a lot easier for me to remember. :P

Most places have a 5pt rating scale with decimal implementation. It is not the scale being used that is the problem, it is the accuracy at which the scale lacks is. It should be to at least 1 decimal place since the average rating is to 2.

If you do revert to a 5 point scale at least let us use 0.5 ratings. I think a lot of us will be annoyed otherwise.

As for the initial post's idea, decimal ratings would mess up the statistics. I find it rather pointless either way: most of the users only use a scale between 6 and 10, mainly. Some use a scale between 7 and 9. No wonder decimals are always suggested. If you want more accuracy, start using a scale from 1 to 10, that would be a good enough start.

If you use a 0.5 scale in a 1-5 system than it is pointless to switch from a 10 pt scale anyway since it is 2 twice the amount. People would then complain that people aren't using the 3-5 rating. Like many have said before decimal placing matters in this kind of rating, or like I suggested before switch to a hundred pt scale to eliminate the need for decimals.

Since this thread is still kind of active I guess there's no harm in bumping it once instead of creating a new topic. After some further thinking I think the 100 point scale I suggested earlier is not a good idea. The current 1-to-10 rating scale suffices if it is used properly.
However, it is not being used to its full potential at the moment. From what I've seen majority's ratings seem to lean towards 6 or even 7 as the average value instead of 5. It is partially explained by how people mostly only pick and rate shows they expect to like so average rating of around 6 is to be expected as the average for such people. But if it reaches or even exceeds 7 for the majority of users, there is a problem with the system.

The current rating system still has a major weakness that makes it difficult to use the 1-to-10 scale to its full potential: the labels make the rating scale positively biased and unintuitive.

First let's take a look at the balance of ratings.

Positive adjectives(50%): Masterpiece, excellent, very good, good, fine
Neutral adjective (10%): average
Negative adjectives (40%): bad, very bad, horrible, unwatchable

There's a clear positive bias when a good rating scale is supposed to be balanced with a clear average line. A positively biased rating scale has tendency to inflate ratings. The expected value becomes too high and the quick plummet from fine level to average level is confusing. It all comes down to the way ratings are labeled.

One issue is the he huge jump from average to fine. If fine was replaced with some word that much more clearly conveys that it's nothing special, like "decent" or "fair", the rating would be much more clear and balanced. In my opinion this would be more balanced and intuitive.

High ratings (10-7) 40%
Average ratings (6-5) 20%
Low ratings (4-1) 40%

And there are some other comments about labels; labeling 10 as masterpiece seems a bit excessive, in my opinion something less intimidating like "excellent" would suffice and keep the ratings a bit more down to earth and applicable; describing things like enjoyability, impact, originality or technical merits as 'masterpiece' is not a very good word for comparison. Same goes for 'unwatchable'.

My suggestion for changes in labels to address these problems are these:

10 excellent
9 great
8 good
7 fine
6 fair
5 average
4 lackluster (some simpler word is better, maybe "weak". I'm not a native English speaker so I couldn't think of anything better)
3 bad
2 very bad
1 horrible

So softer landings and more understandable balance are the changes I think the rating system needs. And just changing a couple of labels should not be a big issue I hope.

I don't think changing the labels will have a significant impact on the rating scale usage.

People complaining about the lack of decimals and using a small rating scale should just start using a bigger scale. People complaining and already using a big rating scale.... well, they're still a problem, but a less important one.

0.5 Decimal Ratings is the feature that I would like to see most, the majority of my anime list are 7's and 8's it would be nice to be able to further distinguish between them.It will probably never happen at this point but oh well.

If you have a majority rated 7 and 8, maybe you should expand the range you rate instead of trying to give decimals. It's not decimals you need, but simply choosing a wider range of scores.

(Yes, this topic is two years old, and I don't see this happening given that more urgent changes haven't been made in years.)
