| Over the past few weeks, I have seen the scores of obscure anime increase significantly. I found a stack documenting the phenomenon, and I have observed similar increases in other titles not found on the stack. Anyone have an explanation for this? https://myanimelist.net/stacks/44765 |

| Score Inflation Bro this needs to be adressed, especially the inflated average score on this app, lol mfs dont know how to rate shit, our generation is doomed. |
| I am a COMPLETIONIST. Aiming to finish AS MANY ANIME as possible before DEATH, Despite them being SATISFACTORY or if they are BORING. I WATCH THE LOWEST SCORED/RATED/RANKED ANIMES ON MAL (OR you can CALL THEM The WORST animes in the WORLD - No Joke Like Seriously) No anime has actually satisfied my anime taste, That I can call a MasterPiece (10/10), still searching... hopefully one day I will find that show and obsess over it till I die. RULE NO.4 I MUST WATCH ALL CONTENT FOR THE SERIES I HAVE FINISHED, NOW THIS ONE IS QUITE EXHILARATING. |
| Wow, there's even a list for something like that. |
  |
| Yes, due to the scoring formula, this site gives a lower score to anime that don't have many votes. Two anime with the same average score might show a different weighted score due to the amount of votes given. |

| I have had a stack called aged like fine wine about about this exact thing. I made it to document shows that have been getting better in the eyes of the community over time. But i don't think that is at play here with the shows in your stack. at least not all of them, like perfect blue is going up cause of the first reason. but it seems like mal has changed something about how the calculate score, that has made the scores be a little nicer to less popular shows. Or at least thats my best guess. |

Lucifrost said: I'm not that familiar with anime trends, but I noticed all titles on that list were old, before 2000 at least. Maybe that's some sort of nostalgia, eg people got tired of copycat shows and looking for something authentic? Anyone have an explanation for this? Also, the shows on the list are not that popular, so they need fewer people to rank them higher to get a visible score advancement. Or maybe some purely technical reason. |

| MAL definitely changed something in the score calculation system, not long ago I checked the median score (not mean score) of the Top Anime ranking, it was 6.55 back then, but now it's suddenly 6.63 and there is no way this could have happened "naturally" within such a short time. |
This dance is the pinnacle of human achievement. |
| They most likely cooked smt behind the screen with the algorithm to obliterate illegal voting as this phenomenon also applied to the Manga board. |
| Still find it funny how much people care about arbitrary anime scores. |
| moeru oniisan score rose just after I wrote the infamous Kimagure Summarized Edition review that was actually a presentation of the new oniisan anime, other that that I don't know |
    |
| I also noticed a sudden increase in the score of a hidden gem I was checking out, but I thought it was due to more people rating it. For those who don't know, the weighted score is calculated by adding 100 votes equal to the global mean (6.50) to every anime. The impact is negligible for the vast majority of anime, but the most obscure ones are severely hurt by that (when they are already rated lower due to the fact that only "expert watchers" are going to bother watching them, not the casuals who rate everything highly). |
 |
| Interesting observation. Some of these have gained quite a bit of popularity over time (e.g. Angel's Egg, Perfect Blue), so it may just have to do that people who are watching these are actually enjoying them. Otherwise, there could be bot accounts adding entries like this to fill out their list in between other entries they are actually trying to manipulate. |

That wouldn't explain why so many titles had their scores increase all at the same time. For such obscure titles, only a few are being watched at any given time. Also, one anime's score went up the day after I downvoted it. 😠 |

| @Lucifrost It looks like a purely technical change then, there are many ways to calculate averages. Maybe ping admins here? They must know if something like that happened recently. |

Does it prevent new entries from getting bumped to the top by a minority? If so, isn't it enough to have a minimum number of scored users to enter the ranking? |

Lucifrost said: besides MAL possibly changing the system unknowingly to us, it's also bcoz of new viewers simply liking them and giving them high scores hence they're going up. It's always been like that. Here is another exampleAnyone have an explanation for this? https://myanimelist.net/stacks/36925 Like Ashita no Joe 2 for instance, pay attention to the statistics. You'll see its 10 score % increasing every couple of days. Btw @APolygons2 i think i've collected another batch for your stack. I might send them sooner or later. |

| @Zarutaku it's definitely an additional measure to avoid seeing random stuff rated by 101 users in the top rankings. They could raise the minimum amount of votes required to have an official score, but then we won't be able to distinguish between obscure anime that managed to be rated 6.xx and the ones rated 4.xx-5.xx or even lower; the weighted score basically just prevents them from being rated above 7.00. |

Nirinbo said: the weighted score basically just prevents them from being rated above 7.00. Shouldn't it also prevent them from being rated below 6.5? The anime I've been watching all had scores below that before the inflation. |

| @Lucifrost no, because it's adding 100 votes, not replacing them. Theoretically speaking, the lowest possible weighted score for an anime rated by 100 users is 50%*1+50%*6.5=3.75 and the highest is 50%*10+50%*6.5=8.25. Of course, these extreme scenarios are impossible: a more likely upper limit might be 50%*9+50%*6.5=7.75. anime rated 7.9 by 100 users -> weighted score = (7.9*100+6.5*100)/200= 7.2 anime rated 7.9 by 200 users -> weighted score = (7.9*200+6.5*100)/300= 7.43 anime rated 7.9 by 300 users -> 7.55 |
