Also to point out, they only compared 1) Short stories 2) Only stuff that you read 3) A particular type of spoiler dependent story 4) They only evaluated how much they preferred it moments after they finished reading it 5) They didn't compare it to rereading the same story after reading it the first time.
Not to say that it isn't possible that I can enjoy stories with the ending spoiled, but the study already has a bunch of holes in it. I'd need to see a replication and some way to control for the above factors before it approaches anywhere near what the realworld experience of spoilers are.
