Seven recurring structural families — revealed beneath five essential domains of human capability.
The thesis: beneath the hundreds of mental models, persuasion techniques, learning methods, performance systems, and negotiation tactics that fill business books, there is a simpler structure. Seven recurring functions appear in every domain where decisions matter. Name them once, and every domain becomes more legible. Make them legible, and every domain becomes more executable.
The promise: after reading any book in the series, you won’t think “I need to remember thirty-five models.” You’ll think “I need to ask seven questions.” The models organize themselves around those questions — available when needed, quiet when not.
