The notes section functions as a second layer of seriousness. It signals that the ideas weren’t pulled from vibe or bravado, but tied to specific research, cases, and supporting material.
For a reader, notes do two things. First, they offer a way to verify claims and chase deeper context when a tactic feels counterintuitive. Second, they clarify boundaries: where a concept came from, how it has been used, and what it is not meant to promise.
That matters because negotiation advice is often sold as magic. The presence of notes pushes the reader back toward disciplined thinking: tactics work in patterns, not guarantees, and the details of context still decide outcomes.
If you want to keep improving, this is where you go when the main text feels too clean. It’s the rough edge behind the polished tool.
