Language: Moderate to High
Cussing, swearing, and other foul language saturates our society today. Science fiction often carries the same, as its worlds are often patterned after contemporaneous times. In addition, the removal of accountability to God, the lack of the sacred, and the devaluing of human life provides little reason to curb language.
Society and technology at its extremes naturally lends itself to higher levels of violence, whether in the form of dictatorial society or biological warfare. On the flip side, technology can provide “cleaner” violence—less gore and blood—than its fantasy counterpart.
Romance and sexuality aren’t usually the main plots in science fiction—something about mixing the unpredictable affairs of the heart with the logical progression of science—unless you’re dealing with a romantic subgenre. However, they do surface in subplots, and these worlds, with few moral bounds, often open the door for promiscuity.
Most science fiction has little use for the supernatural. Scientific explanation is what’s demanded, and the supernatural and magical can’t be explained. Most of the time the closest this genre gets to the supernatural is the unnatural powers of an alien race.
False Religions & the Occult: Low
False religion and the Occult rely on the supernatural. Science fiction rejects the supernatural. So if false religion or the Occult show up, the portrayal is often negative.
Other Worldviews: High
Humanism dominates this genre, and as a result, its amoral views spawn many other problematic worldviews (often in their extreme forms), such as feminism, atheism, homosexuality, environmentalism, and romanticism.
