Off topic, but it bothers me when people decry spoilers for an older movie. As if everybody is supposed to have watched every major film in the history of Hollywood up to the last N years. "Spoiler alert for anybody who hasn't seen this movie from 1980: the dog did it!" Ugh.
Spoilers are a myth and don't affect enjoyment. https://www.nytimes.com/2023/05/08/opinion/spoilers-successi... https://onlinelibrary.wiley.com/doi/10.1002/acp.4070 ' > they were just as immersed even though they knew the outcome. In follow-up questionnaires, they also reported the same levels of engagement and enjoyment as those who didn’t know the ending.
The questionnaires were only used with the study that tested intact, scrambled story and non-monetary incentive. They were not used for the study that tested spoilers (at least I can't find it). Instead they assumed that inmersion equals enjoyment because of the results of an earlier study by them.
All studies were performed using a highly suspenseful short film with a high capacity to engage and a simple spoiler: Telling them if the characters were or not hurt in the movie. This could well be one of the genres more prone to engage you even if you know the outcome. Even more so with a non specific spoiler like that.
I can't find individual data of the study to search for outliers. In my experience some people don't care or even seek spoilers while others avoid them like the plague.
