I think there's something similar in chess where players tend to peak around their mid to late 30s. But a major issue there is that that's also the age that most players are having children and developing ever more interests. And they're competing against the younger generation which is still dedicating 100% of their life, and time, to chess. Absent some monumental edge, that's a battle you're going to inevitably lose - even if aging factors did not exist.
But on the other hand, the world is very complicated and you can't know much in your 20s. I'm today a much better programmer than 10 years ago, even with slightly less brains. You are not going to write an impactfull novel without live experience.
How that declines varies and some people still have most cognitive capabilities in their 70s.
Not everyone survives to write to an old age.
Old people have health problems that can prevent them from work, like going blind.
People who write a great work at an old age will not have the time and energy to do all the non-writing parts of making the great work seen by readers - which has always been a big part of writing. Like getting their book in bookstores, advertising it, etc.
If someone is a very talented writer they are likely to write great stuff before they get old and may spend their old age preening and working on their legacy instead of new works. They will already know they're a great writer, so the drive to make another great work is lessened.
If someone is already an accomplished writer more of their time will be taken up with invitations to speak, being on award panels, doing interviews, writing introductions.
There is less financial incentive to write a great work when you're very old.
It is harder to be part of a literary salon full of smart people that help you grow your creativity when you're very old.
As people grow older they become more alienated from the zeitgeist and are better at connecting with their own generation.
In 6th grade, I had gone to a chess coach who were a friend of my father (technically my father knew his father very well). It was my birthday/a day close to it IIRC and I wanted to learn chess. He was an international-master (or close to it) /National-master (I think he just had one norm less) and he told me about his story and everything, but he said that in a way, he does feel like if he had put the efforts within something like finance for example, he really could earn more than 10 times the money but he said that he really loved chess with a passion. I think that is another element and I think he was within his 30's. Not everyone makes it even that big within chess aside from a very few at the top
You are sort of right in the manner that, as teens grow and the focus of life/dedication from teenage years on solely getting good at chess, diversifies into for example relationships/money-aspects, the mind simply doesn't have enough competition to play chess Comparing this to a 18 year old or 17 year old who just wants to get best at chess and doesn't really want anything else other than chess with their complete and utter dedication.
(There is also another theory recently within Chess of the pressures of being the world champion, from Ding Liren to Gukesh, both have faced tremendous losses after being the best, Gukesh has even lost 75 points after being the world champion, which I believe also has to be because of how many eyes/the pressure building up)
I still like playing chess but all of this makes me also appreciate all the chess players as well in a bit-more behind the scenes manner too. At professional level, calling it taxing sport mentally might even be a bit of an understatement especially for the people within their 30's.
another thing I personally like about Ding and Gukesh both is that they are both humble. They might win or lose but with the brief time that they both had/will have the crown is with their own humbleness. I really like them both a lot. Hope history remembers both their struggles and their humbleness.
He didn't compete for the world champion becaue he didn't want to put in the effort for the preparation (again). Also it would have been boring if he played it because he would have won again.
He intentionally starts with subobtimal openings at major turnaments because of boredom and still wins.
My take on this is that it takes about a decade before experience, knowledge and wisdom can be used to see a bigger picture to make a breakthrough.

a) the curve indicates 30s not 40s
b) there is no breakdown into theoretical vs experimental research, or scientific field; theory I would expect to be over-represented at the younger end especially as the science discipline becomes "harder".
Overall I would say it lends credence to the idea physics is a young person's game at the very highest levels.
b) true there is no breakdown but I would expect the exact opposite as fields get harder. More context requires more training and familiarity, which I would expect to increase age.
My point is that I think there's a bias in the field towards the youth narrative but the majority of discovery, even in physics, happens at a later age.
The exceptions to that pattern are remarkable.
If we expand the definition of pop music to all music that isn’t classical/jazz/experimental, etc. then older, more experienced musicians should be able to do quite well. Frank Sinatra honed his craft over the decades. I think the stuff he did in his 40s and 50s is probably his best.
That being said, I think an interesting factor would also be which of those who wrote major works in their later age already did a decent amount of writing in their earlier years. Even if you have life experience, I would imagine that you will have to build up the "muscle memory" of writing skills in your more elastic years (e.g. by becoming a successful writer after a lifetime of journalistic work or just minor literary works).
I think the best place to look for major works late in life is probably historical writing, which calls for accumulated knowledge and wisdom. Looking at the four most recent winners of the Pulitzer Prize in history from 2023-2025 [0], all appear to be north of 50 based on their Wikipedia pages (which give dates of education if not dates of birth), and one is in her 70s [1].

I can, just from feeling, agree to the pop music. About math I would cite the example of Gilbert Strang, who made many books at advanced age, including one at age 86 or other publications well over the 70s. Another example (well not math, but CS) Donald Knuth. I do not know how is the whole statistic, but writing good books, even text books, does not seem to be teenager thing.
I think there's a chance this is itself a type of selection bias, because you're over-indexing on the famous. And fame has consequences.
Many music artists end up trapped by their own fame (and attendant expectations) and fail to update themselves over time, thus falling out of the limelight. But there are plenty who defy this trend. Tiesto, David Guetta, Kaskade, and Armin van Buuren in EDM, for example. Coldplay is another great example. Love them or hate them, they're still putting out chart toppers.
Something similar is true for scientists in my opinion. I think Richard Hamming had the most incisive analysis of this in 'You and Your Research' [1], which is worth reading in its entirety.
> But let me say why age seems to have the effect it does. In the first place if you do some good work you will find yourself on all kinds of committees and unable to do any more work. You may find yourself as I saw Brattain when he got a Nobel Prize. The day the prize was announced we all assembled in Arnold Auditorium; all three winners got up and made speeches. The third one, Brattain, practically with tears in his eyes, said, “I know about this Nobel-Prize effect and I am not going to let it affect me; I am going to remain good old Walter Brattain.” Well I said to myself, “That is nice.” But in a few weeks I saw it was affecting him. Now he could only work on great problems.
> When you are famous it is hard to work on small problems. This is what did Shannon in. After information theory, what do you do for an encore? The great scientists often make this error. They fail to continue to plant the little acorns from which the mighty oak trees grow. They try to get the big thing right off. And that isn't the way things go. So that is another reason why you find that when you get early recognition it seems to sterilize you. In fact I will give you my favorite quotation of many years. The Institute for Advanced Study in Princeton, in my opinion, has ruined more good scientists than any institution has created, judged by what they did before they came and judged by what they did after. Not that they weren't good afterwards, but they were superb before they got there and were only good afterwards.
My view is that fatalistically assuming that age is an obstacle to creative output obscures the hidden variables that are genuinely determinative.

Not in this case, no, at least as far as the music goes.
My user-name here is taken from a Northern Soul record as its the music that means the most to me. The genre is obscure almost by definition.
I would guesstimate the proportion of the hundreds (thousands?) of records so classified and celebrated made by people under 30 to be over 95% and that correlates with my (admittedly subjective) experience of the best music of other pop genres.
