The latest SMBC made me laugh a bit, so I thought I'd bring extra LessWrong attention to it.
I don't know if pointing out the subject of the comic in advance will make it more or less funny. Knowing that might be more data regarding that recent study claiming that spoilers don't actually spoil stuff...
One other flaw in that study IIRC: they only had subjects read through the stories once. In my experience, many stories can be read profitably twice: once with plot twists unknown to appreciate the mystery and suspense, and a second time (obviously with plot twists known) to appreciate the dramatic irony. The third reading then adds (relatively) little extra.
So if you have a chance to experience fiction spoiler-free, you can get twice as much out of it. But this effect wouldn't be measured in a study where neither group goes through the work twice. You'd merely be comparing the value of "dramatic irony" (for the spoiled group) vs "mystery and suspense" (for the unspoiled), whereas a more fair comparison would be "dramatic irony" vs "mystery and suspense, then dramatic irony".
My caveat doesn't apply to any fiction that isn't worth reading twice in the first place... but that may be a moot point, if like me you believe plot-dependent fiction that isn't worth reading twice usually isn't worth reading once either.
Right. In the shower, I also realized that this is just comparing averages- if, say, 10% of the population really hates spoilers, but the other 90% enjoys them enough to make the average for spoiling higher, it's still sensible to put spoiler warnings as a courtesy to the 10%, because the comparison is "cost to warn vs. benefit of warning" not "spoil for everyone or spoil for no one."
