And sexist.
I subconsciously attribute certain qualities to men and women, and to various ethnicities. Underneath all of the various common jokes -- "Asians are good at math", etc. -- there is an undercurrent of discussion where other people are admitting their biases, too.
When I get on the phone with technical support and hear a thick East Asian accent, the first thing that happens is I grit my teeth. I feel frustrated that I am having to try to resolve a technical issue with someone that I have to actively concentrate on in order to understand clearly; I feel annoyed in expectation of their overstated politeness; I am immediately resigned to not getting the problem resolved at all, as they are probably going to ask me to troubleshoot a networking problem by rebooting a computer.
These are biases that have been built up over a period of many years of similar experiences, one little bias at a time. And, when the call actually resolves the issue quickly and without any frustration at all, I find myself thinking, "That went better than expected."
I recognize this about myself. So, when I notice these things happening, I consciously moderate my tone, and try to consciously manage my opinions and feelings and statements. But, that doesn't change the fact that the bias is there, affecting my subconscious.
Likewise, for women in tech. I know there are amazing women in technology, and in other male-dominated fields. I'm occasionally fortunate enough to work with some of them, covering a wide range of other demographics. Still, when it comes time to hire again (someday soon, I hope), applications from women will first be met with biases built up one-by-one from a lifetime of experiences: all the various women friends that need help "fixing their computers", or of a past applicant who we hired, presented with an easy starting project and clear instructions -- "no coding necessary, just do some nice-looking Photoshop mockups" -- and who called, the next day, saying that she had cried all night and talked to her mom because she didn't think she could do the work because we used iframes in an ajax-y way.
Or, when I hear about a black entrepreneur. The first thing that bubbles up from my subconscious is, "Wow, they're succeeding in spite of modern black culture." I have to beat that thought down and consciously regard them as an individual.
These are uncomfortable admissions to make. I would be loathe to admit them in more polite company. Terms like "racism" and "sexism" themselves carry strong biases -- that the only forms of "racism" are "white superiority" and the only forms of "sexism" are blatant misogyny and creepy sexual undertones.
But, racism and sexism and other -isms are a part of who we are, a part of our psychology that dates back to our tribal and "us versus them" cultural influences. I think that trying to pretend that they don't exist is only going to prolong their effects.
Knowing that they exist can help us make better decisions.
