I feel like this advice from Derek Sivers makes sense in conversation but not, say, when writing, which makes it all the weirder that he specifically cites being annoyed when books do it. We reference sources because Sivers’ suggestion that “if I hear an idea, have considered it, and integrated it into my beliefs, it’s mine” might be true to a degree but not to the degree that you can give the impression that it just sort of popped into your own head one day. It’s one thing that we naturally absorb ideas and incorporate them into how we view the world around us without realizing. It’s entirely another thing to be consciously aware of one’s sources and just sort of decide they don’t matter unless someone asks.
