It was not just the ninja question, though that was part of it. The Star Wars v Star Trek one as well. They definitely contributed to a sense of “oh, this isn’t about you. This is about ‘real’ developers,” especially when placed in the context of all the other background noise of being an statistical outlier in my field.
Maybe just asking “what do you think of labels or descriptions like ‘ninja, guru, etc’ when they’re used in job titles?” would be a less clever but more straightforward path towards that objective.
