The question "Do spoilers increase enjoyment of a work?" quotes a university website on which recent empirical research from the field of psychology is summarized. The author of the question appears to doubt the reported results based on a common sense argument that he/she invented and which is not backed up by any evidence.
Basically, what the author does is call into question a finding that has been (presumably, the research itself is not easily accessible) produced by applying the scientific method, on grounds of not believing it can be true. To me, it seems that is the exact opposite of applying scientific skepticism.
Are questions of this type, which somewhat exaggeratedly may be paraphrased as "scientists claim something that I, a layperson, don't believe – is it true?", on topic for this website, which hails to be a "Q&A for scientific skepticism"?
