Before you buy

You'll start to hear where someone's attention goes and what they bring up unprompted. Naming a type after one conversation is another matter; the book doesn't promise it. It's the first step, and practice comes next.

Only as a draft. Your own type can't be heard from inside: the same head would have to judge and be judged, as the book says plainly. An outside ear can confirm the version: “Exact type assessment from speech semantics”.

You don't need to know anything going in. The book introduces its terms one at a time and shows each in sample conversations: a trip, a fight, a work meeting. All it asks is that you can listen.

Because it teaches you to hear rather than describing anyone. The ear is the same whoever you're listening to. Your type is in there too: its page in Part V, with how it sounds and which type it's often confused with.
