I admit I'm pretty lackadaisical when it comes to worrying about ensuring that I start each and every book with complete ignorance of every single plot point or event that happens (or doesn't happen) before hand. Nor do I think it's reasonable of those who are afflicted by extreme spoiler-phobia to expect the entire internet to cater to their special needs (especially when they are actively perusing book-related threads and topics before they've finished said book). But now, I have data that shows it's all moot anyway.
I'm not saying the data is valid, or even empirical... only that it's data... and it happens to coincide with my opinion on "la, la, la—I'm not listening to you—shut up before you ruin it all for me" nonsense.
