Annals of mathematics : probability and statistics

Georges de la Tour – Les joueurs de dés, vers 1640.

Recently, during a coffee break, emerged a discussion about the presence of probability and statistics in top journals such as Annals of mathematics, Acta Mathematica, Inventiones Mathematicae, or Journal of the AMS. Well, the question has an interest from the point of view of the sociology and history of science. Let us use the Primary and Secondary Mathematical Subject Classification (MSC) codes of each article in order to detect Probability (60x) or Statistics (62x). Here is the data from MathSciNet/zbMath:

  • Annals of Mathematics published 4464 papers in total from 1938 to 2019.
    Among them, 76 (1.7%) have Primary MSC 60x [PDF]
    Among them, 112 (2.5%) have Primary or Secondary MSC 60x [PDF]
    Moreover only 2 have Primary or Secondary MSC 62x [PDF]
  • Acta Mathematica published 1297 papers in total from 1938 to 2017.
    Among them, 44 (3.4%) have Primary MSC 60x [PDF]
    Among them, 63 (4.9%) have Primary or Secondary MSC 60x [PDF]
    Moreover only 4 have Primary or Secondary MSC 62x [PDF]
  • Inventiones Mathematicae published 4311 papers in total from 1966 to 2019.
    Among them, 52 (1.2%) have Primary MSC 60x [PDF]
    Among them, 95 (2.2%) have Primary or Secondary MSC 60x [PDF]
    Moreover only 2 have Primary or Secondary MSC 62x [PDF]
  • Journal of the AMS published 963 papers in total from 1988 to 2019.
    Among them, 28 (2.9%) have Primary MSC 60x [PDF]
    Among them, 49 (5.1%) have Primary or Secondary MSC 60x [PDF]
    Moreover only 5 have Primary or Secondary MSC 62x [PDF]

The presence of probability is low, while the one of statistics is microscopic. A scandal.

AO(P|S). Annals of Probability (AOP) and Annals of Statistics (AOS) were founded only in 1973.

1938. Annals of Mathematics is historically American whereas Acta Mathematica is European. They started respectively in 1892 and 1882. According to MathSciNet, it seems that the first article classified 60x in these journals was published in 1938. The MSC by itself was introduced at the end of the thirties and many articles in MathSciNet are not classified before 1940 at the time of writing. Note that N. Wiener published in the twenties while A. N. Kolmogorov published in the thirties.

Why. The phenomenon has probably multiple explanations, among them we could mention for instance the possible effects of utilitarism and anti-utilitarism in the mathematical elite, in particular during the fifties and sixties, and the possible overweight of some kind of “snobish pure mathematics or mathematicians” in top journals boards. We could also see AOP and AOS as some sort of mathematical ghettos and think about self-censorship. We could moreover think about generational effects. Finally we have to keep in mind that some probability papers were published without any primary or secondary 60x code, such as for instance this one  or that one.

JMPA. We could think that a journal such as Journal de mathématiques pures et appliquées, founded in 1872, is in the same time relatively prestigious, generalist, and more open to applied mathematics in general and to probability and statistics in particular. Here is the data for all MSC codes, taken from MathSciNet. We see an obvious overweight for partial differential equations. In the mean time, the situation of probability is better than before, while the presence of statistics is still microscopic.

CPAM. Finally, here is the same data for Communication on Pure and Applied Mathematics. This journal, established in 1948, is truly open to applied mathematics in general and to probability theory in particular. However, the presence of statistics is still extremely low.

    It would be interesting to check if it is the same for mathematical physics, numerical analysis, mathematical biology, imaging, game theory or mathematical economy/finance that we have at Ceremade !!! I guess that the results of « analysis of PDE » would give higher scores because of the “pure math” style of some of it.

    By the way, check the y-scales of the graphs 😉 Strange that all bottom values are 1.

    Thanks Amic! I have just fixed the graphics (the data contained too many years with zero entries…). Yes we could play with other parts of applied mathematics especially with the ones that we have at Ceremade. I have just added a table for Annals of Mathematics with all MSC codes, idem for Journal de Mathématiques Pures et Appliquées, and for Communications on Pure and Applied Mathematics.

    En fait c’est assez édifiant… mais une fois cette voie engagée, j’ai peur que nous en soyons nous-memes les fautifs…
    Nous n’envoyons pas de papiers a annals of maths parce que nous avons du mal a visualiser ce qui serait encore mieux qu’un resultat a ptrf ou AoP… faut-il une portée plus générale? un resultat completement en rupture? mais qu’est-ce que tout cela….
    voir meme, lorsque j’ai à référer des papiers dans ces journaux… difficile de savoir ce qui passe la barre… car peu d’exemples (bon et visiblement quand j’ai dit oui, l’editeur a dit non… )…
    en tant qu’auteur j’ai eu de tres bons avis des rapporteurs pour ne finalement pas être accepté… trop spécifique…
    On a une impression de chasse gardée et que nous-mêmes nous n’essayons pas assez…

  4. Djalil Chafaï 2019-11-12

    Oui, je suis d’accord : les probabilistes et statisticiens ont eux-mêmes entretenu le phénomène en s’enfermant sous un plafond de verre fait de AOP, AOS, … et en faisant preuve d’auto-censure. D’autre part, les comités éditoriaux de AOM ou Acta auraient pu faire preuve de clairvoyance et d’ouverture et diversifier leurs membres. La situation actuelle semble être autant due aux uns qu’aux autres.

  5. Fabrice Baudoin 2019-11-27

    Merci de cette analyse quantitative. Cela montre qu’en effet il n’est pas tout a fait raisonnable de considerer qu’un journal comme Annals of Mathematics est un top journal en mathématiques; plus précisément, c’est un top journal dans certains sous-domaines.
    Je suis d’accord que la situation est due d’une part aux probabilistes, qui finalement ne pensent probablement pas toujours a envoyer leur meilleur papier a AOM, et d’autre part aux éditeurs d’AOM qui historiquement ont plutôt favorise d’autres domaines selon leurs preferences personnelles.

  6. Djalil Chafaï 2019-11-28

    Un collègue statisticien m’a expliqué que de son point de vue de statisticien, c’est publier dans AOM qui lui ferait entrer dans un ghetto, celui des maths pour les maths. Ça n’est pas faux, mais c’est un état de fait qui est issu d’un processus historique qui a produit l’état stationnaire qui est le nôtre, et ce processus aurait pu être différent. AOM a publié un peu de statistique dans les années 40/50 (Wald et Wolfowitz).
