The evidence seems to be mixed, with successive experiments contradicting (or at least nuancing) one another, as a quick ‘Spoilers reduce enjoyment’ Google search shows.
I really appreciate your bringing this topic as it has allowed me to update in the direction of worrying less about the possibility of coming across a spoiler: upon further reflection, I conclude that, at least for me personally, they do not seem to affect my enjoyment as much as I thought they did, and in some cases, they even add to the experience rather than subtract from it. I have an issue with face recognition, which leads me to getting lost in the plot of e.g. movies with a lot of different characters. Knowing part of the plot in advance helps me being engaged.

Note that I meant to say that I personally really dislike spoilers despite the ‘scientific’ evidence saying that I don’t. But it could very well be that the evidence is actually mixed (thanks for the link!); I hadn’t looked into it more than seeing 1 or 2 papers shared on Facebook.

You did that well:)
