You are judged and reviewed on a myriad different factors other than this. Are you a "team player?" Do you mentor others well? Do people like you? Were you picked to do complex projects this review cycle? Are you too loud? Too timid? Do you ask insightful questions? Is your coding style "normal"? Do you dress professionally? Can you be asked to interface with clients?

Every little thing that can be used will be used to form a composite picture of you as a person. It's wrong to expect a foreigner like me to be judged on whether I know baseball stats but I'm sure someone somewhere has made an inside reference about baseball around me and written me off when didn't even acknowledge it.

That's what diversity programs and affirmative action programs try to short circuit.
