Well I'd say, in general, people don't enjoy what they don't understand. Scientific research and concepts are not easily grasped, and true attention and mind dedication is needed to learn new concepts in such a field. As a result of it's difficulty, many individuals choose to spend time watching more easily understood programs, such as those hillbilly shows, and as a result, miss out on the interesting-but difficult to understand- science behind the world around them. If enjoyment is what the average person seeks, then they will find the easiest method to retrieve it, hence watching noneducational television for pleasure. It all comes down to effort and persistence, based on if an individual is willing to work harder for the reward.
