Cold brain = the part of you that thinks like a computer.
Hot brain = emotions, gut feelings, instincts, procedural memory, the stuff that guides your actions.
Is there a better term for this? If not, I'm going to start using the terms "hot brain"/"cold brain" a lot. It really concisely describes something I often want to talk about. For example, it's easy to learn in your cold brain that smoking causes cancer and that you should quit smoking. But it's hard to convince your hot brain, which is why quitting smoking is hard. Or, it's easy to learn vocabulary in a foreign language (cold brain) but hard to come up with it as you speak (hot brain).
