- novelty bias - first episode usually have high scores
- usually the ending episode will have a good boost in the overall score of the anime
- sequel effect - sequels usually have higher scores since the haters stop watching and only fans remain watching the sequels
- recency bias - new anime tend to have higher scores
- old anime tend to have decreasing scores over the years
- there are more binge watchers than ongoing weekly watchers
- currently with 12 million members once an anime reach 180k members then its part of top 1000 popular anime out of the current 19K anime in the database

so can you add more? and thoughts?

- novelty bias works only when the first episode has very good production value (then if the writing of the following episodes is bad the score will drop) or if the fans of the source material are enough (so it works like the sequel effect)
- the score boost after the last episode only happens if the ending is very well liked (Odd Taxi, Steins;Gate); the score remains more or less the same more often (a little boost quickly nullified by score degradation)
- recency bias and score degradation are both caused by the fact that die-hard fans of a specific genre will watch a related anime as soon as possible, whereas those who care less will take their time

other ideas:
- controversy bias. The more explicit an anime is in terms of violence and sexuality, the lower it will be rated
- popularity bias. The more an anime is popular, the more it will be watched by newcomers, which have lower standards, thus inflating its score
- "status of classic" bias. The score of some old anime is increasing instead of degrading (Monster, Nana, Banana Fish, Serial Experiments Lain to name a few). I think it happens because they achieved the status of "classic", so new watchers are seeing them more positively
- bandwagon effect. When a new season comes out and it's rated much higher than s1, the score of the latter will raise as well (Fruits Basket, Kono Oto Tomare!, Dragon Maid). I'm not sure if it's just the influx of new watchers, or there really are so many user fixated on giving the same score to every season of a franchise.
- Netflix jail effect. Beastars score falling from 8.42 to below 8.00 in a little more than a year is unprecedented. My own explanation is that those who watched it on Netflix liked it much less than those who did it on illegal streaming sites when it was airing. Why? It is reasonable to think that those who'll bother using obscure ways to watch anime are tendentially more expert watchers and thus less outraged by the furry content.

controversy bias and Netflix Jail effect are great additions

im not sure about popularity bias though, since the more the anime becomes popular the lower its scores get overtime due to 1/10 scores having more weight than 10/10 scores

- novelty bias
Since you seem to believe art is subjective, you could rename these to "novelty factor", since bias seems to imply a departure from objective fact. Instead, what you mean to say is that novelty, recency, etc., affect the subjective impression. Not that there is some intrinsic value to art, and novelty, recency, etc., throw our judgment off.

If you do mean the latter, then you could not possibly think art is subjective. These are contradictory views.

Yours is a valid hypothesis, but I'm not really sure. On the contrary, I'd say that the 1/10 votes hurt less popular series even more precisely because they aren't watched by newcomers who rate everything 9 or 10 (for example, Aria the Origination: 8.99 on RedditAnimeList, 8.50 on MAL).

I don't think this bias gets enough acknowledgement.

- Netflix jail effect. Beastars score falling from 8.42 to below 8.00 in a little more than a year is unprecedented.

The opposite also holds true, due to popularity bias. Movie scores often go up after they hit streaming services.

This is indeed true in most cases, due to popularity bias.

I called it "Netflix jail effect", but actually it's something that specifically addresses Beastars. I think it's due to its controversial nature coming out only towards the end of the season, whereas Dorohedoro (another victim of Netflix jail and also possibly controversial) would be instantly skipped by those who can't stand violence.

I just checked on Wayback Machine: Beastars score only fell by 0.02 two months after it finished airing in Japan, when it still was in Netflix Jail. Then it was released worldwide and lost a whopping 0.20 in three months. it can't be a coincidence.

I think that without Netflix jail the score would simply have dropped more quickly. Erased was in the top 10 while it was airing, but scores like those never last after the hype dies down.

Unpopular anime generally have scores that are a closer indication of their quality since the only people who would bother to watch them are those who actively seek out anime apart from the norm.

The last episode boost is due to those dedicated to sticking through the show are the ones who liked it.

MAL rating does not define whether an anime it is good or not.

so can you add more? and thoughts?

novelty bias: that's to be expected since nowadays there are more and more of what we call "normies" watching anime. they're like young weeb and thus anything they watch will be an immediate 10/10 but they forget it instantly after :)
the ending thing: endings can make or break a show (examples are wonder egg{bad ending} and code geass{amazing ending}) so if its good then i'd expect it to have a slightly higher score.
sequel effect: i kinda agree with this but not quite . . . i mean we all watched sao to the end right?
recency bias: no objections here. you're absolutely right on this one.
old anime scores being deteriorated: that just dumb peoples need for attention and they satisfy it by saying "look at me im so special, i dont even like good shows"
bingeing vs weekly watching: this one it tricky. its defiant for each anime. generally, plot-driven stories will be better enjoyed if binged and on the other hand, episodic series are better weekly. and if the anime in question is not either of these, then idk what happens kek.
the last item: i have no comment :)

------------------------------------------------------------
some other things that might affect the score in an unfair way:
1-mal people changing their system (like in the case of interspecies reviewers)
2-the "normies" that i mentioned
3-super fans (im looking at you fmab fans!)
4-lack of a ranking guide: i've seen people saying stuff like "my list is based on my personal enjoyment" which is always a bruh moment cuz i thought you were supposed to rate stuff as objectively as you can.

Erased peaked at 9.14 while it was still airing, what matters is the score right after the final episode.

score right after it finished airing -> 2 months later -> 3 more months later
Erased: 8.76 -> 8.75 -> 8.69
Beastars: 8.44 -> 8.42 -> 8.23

Come on you people. It's 2022. Paying attention to MAL's scores/system/lists etc is extremely pointless. You're just wasting your time. One number doesn't necessarily justify a title's quality anyway
