Maybe I'm lucky, but predictable plot twists just don't occur to me while I'm reading. I'm just there to enjoy whatever story I'm being told, and it just doesn't occur to me to try to guess what will happen next or how the author will resolve the story.

I only think The only exceptions are detective novels where the whole premise of the book is for the reader to try to figure out what happened (I'm terrible at it), and stories with fairly obvious secrets that are extremely important to the plot (gee I wonder where that 7th horcrux could be).
