Oh, so that explains it

I am immediately skeptical of studies that attempt to assign behavior patterns to concrete topics, but even if these findings are more amusing that informative, it’s worth a read:

Not everyone enjoys a murder mystery with a surprise ending, new research suggests.

People who have lower levels of self-esteem prefer crime and detective stories that confirm their suspicions in the end, while those with higher self-esteem enjoy a story that goes against expectations.

"Personality
plays a role in whether a person wants to be confirmed or surprised
when they read mysteries," said Silvia Knobloch-Westerwick, co-author
of the study and assistant professor of communication at Ohio State
University.

"People with low self-esteem like to feel they knew
all along who committed the crime, probably because it makes them feel
smarter."

But overall, Knobloch-Westerwick said that mysteries probably appeal more to people who enjoy thinking more than average. “The mystery genre is one of the more complex
genres,” she said. “Mysteries have multiple suspects, and multiple
possible motives, which all add complexity. It is much different than a
suspense story which just has a good guy vs. a bad guy.
