Most of the people who watch horror movies are 17-18 years old, so the trailer needs to appeal to this key audience with things they enjoy like jump scares and fire. While the survey found more females watched horror, males likely did not complete the survey, and males often enjoy the adrenaline of being scared. The survey also found that jump scares, death, and an easy to follow storyline are the most conventional elements, so the trailer and movie must have these to be successful.
