This reminds me a story from my childhood. I was brought up by my mother, who is a very smart, independent and strong woman (and a hacker!). One day, when I was about 9, she asked me who, in my opinion, is usually more intelligent, man or woman. Without hesitation I answered that women are. It was the first time I learned that most of the world probably doesn't think like me. We're all biased, there's nothing to do about that, but publishing and broadcasting your bias is dangerous because it helps make it real.
