Statistically speaking, if 100% of bike thieves are male (in a certain location) then the inherent, and justifiable, bias from the population would be towards males. No data lookup needed.
But also, I think that it wouldn't matter the race or sex, if someone was in your home who you did not invite, or know them. And based on their behavior, skin color, clothing, would determine if you said "hi, you must be my daughter's friend?" or "What are you doing in my house, I am calling the police!"
But no one wants to admit they make judgements about anything, because that's sexist/racist/something-ist.
How many people in that area know that 100% of bike thieves are male? I sure don't know such statistics for my area. That's the "data lookup" that's needed - to make decisions based on statistics, you have to know the statistics.
I guess nobody knows, but what is the explanation for people's reaction? If the town only had women bike thieves, do you think the experiment would have gone the same?
