Other mnemonic: on any problem you're thinking about, system 1 responds first, system 2 is second.
System 2 is always second cause it's slower. (Because it's more methodical, etc. etc.)
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.
