I’m confused about your example; who is closed-minded and who is open-minded? (Serious question) I otherwise disagree with the dichotomy in the first paragraph. It seems to me that one might be open-minded and contributory. On the topic of “opining vs. voting”: what’s the difference? Additionally, couldn’t the retail employee go vote and have the same sort of measurable external impact? I guess I’ll attempt to answer the question in the comment: all else being equal, an open-minded person is more valuable to society than a closed-minded one.
