Your example of sports is very interesting. I agree that above a certain
level, any team etc. is inherently notable. There is still, however, the
question of available sources,
I'm not a sports connoisseur, but if I go to a typical library, there is
a range of books on popular *male* sports. I can find biographies of
famous players, histories of major clubs, etc. A quick Amazon search for
instance shows me that they have a book on sale about the successes of
AS Saint-Etienne in the French football (that's soccer for Americans)
championship in 1976!
I do not find such books on female sports. In fact, if I look for a book
on the French women's soccer team on Amazon, I find something...
extracted from Wikipedia! (Recall that football is the most popular
sport in France...)
In short, for certain topics (e.g. male sports), there is a gazillion
books, biographies, and other source material readily available, while
for others (e.g. female sports) such sources are more difficult to find.
What I would like to understand is how much the bias is caused by such
imbalances in sources. A possible evaluation method would be to consider
female and male personalities (e.g. writers) equal in notoriety (e.g.
according to scholars from that field), and to compare the length and
quality of the biographies. What do you think?
