> they either get it because they've read that book, or they understand that they don't and can save themselves a lot of time and confusion and ask what you mean. I've read that book and several other works on the subject and I still can't remember which one is system I and which is system II. I get why they use those labels (because they don't want to pre-suppose the characteristics of what they're investigating). But I do find them frustratingly undescriptive.
