I remember reading an article when I was a teenager about how very few men, but most women could tell whether a specific disease (don't remember which one) was caused by a virus or bacteria. It also claimed that the statistics were reversed for knowing whether the sun revolves around the earth or vice versa. I had no idea about the virus/bacteria thing, felt ridiculous to me. But intrigued, I asked my mother about the sun and earth and she responded: "I don't know, I've never even thought about it". Shocked to say the least. I learned that day that men and women are very different on average, despite being told otherwise my whole life.
