If something in a movie is spoiled for you before you can see it, it may harm your movie watching experience.
BUT apparently, spoilers actually can HELP a movie’s performance in the box office.
Some researchers from Western University and the University of Houston found that spoilers positively impact a movie’s box office performance.
This is because spoilers can give moviegoers “plot-related content” to help them decide to see the movie or not.
So long story short, spoilers are being used to reduce the uncertainty in movies.
