Why fiction is good for you: How fiction changes your world - The Boston Globe
the most impressive finding is just how fiction shapes us: mainly for the better, not for the worse. Fiction enhances our ability to understand other people; it promotes a deep morality that cuts across religious and political creeds. More peculiarly, fiction’s happy endings seem to warp our sense of reality.
“Researchers have repeatedly found that reader attitudes shift to become more congruent with the ideas expressed in a [fictional] narrative.” For example, studies reliably show that when we watch a TV show that treats gay families nonjudgmentally (say, “Modern Family”), our own views on homosexuality are likely to move in the same nonjudgmental direction. History, too, reveals fiction’s ability to change our values at the societal level, for better and worse.
Fiction is dangerous because it has the power to modify the principles of individuals and whole societies.
But fiction is doing something that all political factions should be able to get behind. Beyond the local battles of the culture wars, virtually all storytelling, regardless of genre, increases society’s fund of empathy and reinforces an ethic of decency that is deeper than politics.
