Does anyone know or what would your best guess be when it comes to the ratio of male/female readers of Sci-Fi/Fantasy? I would think fantasy appeals to more women whereas sci-fi appeals to more guys. I ask because my brother who is out of the nerd loop due to raising teen girls was telling me about an article about N.K. Jemison he read that was hyping her as the biggest name in sci-fi today and he was surprised since he felt she just peddles the usual left wing nonsense in entertainment. I then told him about the sad puppies movement and to avoid modern sci-fi and fantasy like the plague.
I am a huge reader and there are a lot of women who read heavily but like everything certain genres appeal to men more than women and vice versa.
Women tend towards wish-fulfillment fantasy and fatasy-scifi, where technology is magic to help them get married or take over a world to prove how correct they are.
Men tend towards adventure in both genres. A well-written plot doesn't even need action sequences, but it helps.
