One book, its roots, and everything that grew from it

Every node is a work; every line a citation. The seed book — Medical Thinking: The Psychology of Medical Judgment and Decision Making (Schwartz & Griffin, 1986) — sits at the centre. To its left, the roots — the works it cites. To its right, the branches — works that cite it. Scattered through the modern era, the AI decision-making literature — a systematic sweep across 26 themes, from rule-based expert systems to LLM clinical reasoning — linked by shared concepts rather than by citation. Position on the horizontal axis is publication year, so the graph's hourglass shape is literal: everything narrows through 1986.
