Just so. These are the sort of "inter-individual variation in hedonic spoiler effects" I had in mind earlier.

Edit: to elaborate a bit, it was the "error bars look large enough" bit of your earlier comment that triggered my sceptical "Really?" reaction. Apart from that bit I agree(d) with you!

Edit 2: aha, I probably did misunderstand you earlier. I originally interpreted your error bars comment as a comment on the statistical significance of the pairwise differences in bar length, but I guess you were actually ballparking the population standard deviation of spoiler effect from the sample size and the standard errors of the means.
