Use inclusive pronouns when talking about roles or users. For instance, use "the user" or even "she" instead of assuming "he". It might take some effort, but it's worth it.
A couple months ago, Jake joined my team. On his first week, we were discussing various user journeys and I heard him say, "If the user clicks on the submit button, she'll be directed to the confirmation page."
I was shocked (and very happy). I had never heard anyone use the female gender when discussing a generic user. As soon as he said it, I felt instantly acknowledged. Then I started thinking about how many times I've heard the male default and felt alienated.
The challenge is that English is a gendered language (although not as gendered as some other romantic languages, which ascribe gender to inanimate objects). There aren't good generic ungendered ways to talk about a person in English. As a counter example, Mandarin has a singular word tā to describe a singular person. The best I've been able to come up with on my own is saying "the user" and the pronoun "they", which doesn't have the best grammar. But even I slip up on occasion when talking about recruiting for my team, occasionally saying "he" when there's no assumption that role should be filled by a man. In fact, I'd love for it to be a woman. But when women are 1 of 10 for the role being recruited for, I've slipped into unconsciously assuming a male to fill the role. Here, I often correct myself, but feel guilty for my mistake.
All of this to put even more emphasis on my delight when I heard Jake say "she".
I decided to ask Jake about how he arrived here, and he said he's been doing it for the last four years:
There were a lot of gender conversations going on at college, so I felt I should be more conscious of how I thought and spoke about gender. A couple of my computer science textbooks also defaulted to female subjects. This struck me as a great way to build in some automatic empathy, and also to have a benevolent default that I could be sure would not offend. Beforehand, I had actually felt a little strange every time I defaulted to a male subject, even though that was my prior habit.
The adjustment definitely required some ongoing effort. At first, it took very conscious thought to make sure I was being consistent. Lots of weird sentences where I would say things like, "Then he got into her car." But after a few months (I think it did take that long) it became very automatic, and I've spoken like that ever since.
For me, I'm not sure if I feel comfortable always adopting the female subject, but I know I'll be encouraging myself to continue to use inclusive nouns and pronouns. And I was delighted to see Google's recent promotion training include "she" on slides. There are many opportunities around us to second guess our gender assumptions with something as simple as a pronoun. And as Jake says, even if you make a slip, it's worth it to make the adjustment midstream. Someone will notice and likely be very appreciative.
