#583 Anecdotes versus Data in Leadership: What D-Day Teaches Decision-Makers | Niels Brabandt

What is your decision based on? Many leaders answer that question with seniority: "I have twenty years of experience." In this episode of The Leadership Podcast, Niels Brabandt explains why experience and anecdotes are a starting point, not a foundation, and how leaders can move from what someone heard to what the data actually shows. Drawing on the 2026 film Pressure, Niels Brabandt revisits June 1944, when meteorologist James Stagg persuaded General Eisenhower to postpone D-Day by one day. Stagg's forecast was backed by data; the competing forecast relied on historical precedent. The storm arrived exactly as predicted, and the landings succeeded in a narrow window between two weather systems. Business decision-makers will learn: Why anecdotes matter, and why stopping at them is dangerous How to test the "our competitor does everything with AI" claim before investing Why the time available determines the standard of evidence you should demand What Eisenhower's "in case of failure" note teaches about accountability How to build decisions that are sustainable, not merely convenient A practical, evidence-based episode for executives, managers and anyone responsible for decisions that matter.
