I tend to deliberately avoid the situation with a variety of alternatives, including, but not limited to
the user and
they. And in any case, it simplifies the issue a bit because once you use
she you have to concern yourself with use of
I am not alone:
The Microsoft user experience guidelines is about 880 pages and refers to
he in just one sentence,
she in just two different sentences, and
he or she in just one. But
the user is used 550 times and
they 384 times
The Apple Human Interface Guidelines does not use
she once in some 280 pages but
the user comes up about 445 times and
they 835 times.
[Those figures are adjusted to exclude
the user when used as part of the term
the user experience]
I can't speak for scientific writing generally, but I do find it 'of note' these days when a text chooses to use
he. I don't see that choosing the opposite of
he really addresses the balance so much as tries to overcompensate for what I agree has been an imbalance in the past.
But you are asking an audience that is probably somewhat biased towards
the user !!
