Correct, that is another instance of the same reasoning pattern with high inductive probability. I see no evidence of cognitive bias in either case.
My point is that the fact that the probabilistic inference is valid does not imply that you should e.g. use examples that assume the user is that way, which was the reason you were making that point to begin with. I can safely assume that an unknown user is male. Doesn't mean I should use male-experience specific examples for elucidation.
Recently, I have noticed a cultural bias for the United States running through LW threads. It is perhaps to be expected of an English-language website, but for one that is about, among other things, overcoming bias, it is important to recognize one's own.
Aspects of the bias I have observed include:
I'm not the first to raise such concerns, either.
By comparison, e.g. the English Wikipedia strikes me as an example of an international English-language project that's relatively successful at recognizing and fighting systemic bias, and a whole set of template messages to mark articles with identified problems.
To quote Wikipedia itself:
The reason I haven't mentioned other obvious biases, such as gender, age, education, or First World biases, is because those (in my experience) tend to be more subtle here on LW and because I'm myself subject to some of them. However, I might cook something up on them later.
