One of my favorite movies is When Harry Met Sally. I can watch it again and again and love it every single time - maybe even more than I did before. There’s a scene that will be familiar to any of the movie’s fans: Harry and Sally have just set off on their drive to New York City and Harry starts telling Sally about his dark side. He mentions one thing in particular: whenever he starts a new book, he reads the last page first. That way, in case he dies while reading it, he’ll know how it ends. Harry will know how it ends, true, but doesn’t that also ruin the book? If you know the ending, how can you enjoy the story? As it turns out, easily. A study in this month’s issue of Psychological Science comes to a surprising conclusion: spoilers don’t actually spoil anything. In fact, they may even serve to enhance the experience of reading. Over 800 students from the University of California San Diego took part in a series of three experiments, where they read one of three types of short story: a story with an ironic twist (such as Roald Dahl), a mystery (such as Agatha Christie), and a literary story (such as Raymond Carver). For each story, there was a spoiler paragraph that revealed the outcome. The students read the stories either with or without the spoiler. Time to reconsider, it seems, what we call a spoiler. The so-called “spoiled” stories were actually rated as more enjoyable than those that were “unspoiled,” no matter what type of story was being read. Knowing the ending, even when suspense was part of the story’s goal, made the process of reading more, not less, pleasurable. Why would this be the case? Perhaps, freed from following the plot, we can pay more attention to the quality of the writing and to the subtleties of the story as a whole. Perhaps we can be more attuned to those signs that foreshadow the unfolding of the action and take pleasure in our ability to identify them. Whatever the case may be, it may not be as urgent as we think it is to avoid spoilers. Indeed, it might be just fine to embrace them openly. Harry might have the right idea after all. In fact, he might be getting at the very thing that lets me watch him meet Sally over and over and over again, and enjoy the process every single time.
