Purushothaman, Deepa, and Colleen Ammerman
Harvard Business Review, 10 March 2026
Conceptual debt beneath the chapter’s broader account of leadership under pressure. The article supports naming uncertainty, making explicit value-anchored trade-offs, sharing responsibility and modelling boundaries. It does not describe the chapter’s two-type split and is not evidence for the observation that some leaders centralise every decision.

First Drafts, LLC
First Drafts, n.d.; accessed 31 July 2026
The official product page identifies First Drafts as a generative-AI system for producing first drafts of litigation documents. It also says plainly that the system is not hallucination-free and that its output must remain a draft for a lawyer to review. The court order, rather than the company website, is the source confirming that Kathleen Wilson used it in Withers v. City of Aberdeen.

The source behind the chapter’s hopeful reading: AI changes how human skills are used rather than making them obsolete. It supports the shift from producing first drafts to framing questions and interpreting results, and the continuing importance of judgement, problem-solving and negotiation.

Used cautiously in the discussion of cognitive debt. It was a preprint, not yet peer-reviewed, so the book treats it as an early warning rather than a settled verdict.

Wedell-Wedellsborg, Merete
Harvard Business Review, 23 March 2026
Conceptual debt for the withdrawal half of the chapter’s leadership observation. The article describes leaders losing agency and withdrawing from decision-making and the emotional labour of leadership under prolonged volatility. It does not support the separate observation that some leaders pull every decision into their own hands and become bottlenecks.
