Anchoring bias, latching onto the first story and ignoring everything that doesn’t fit, doesn’t just cause diagnostic errors. It can destroy lives.

In this gripping bonus/true crime crossover episode of the Scalpel and Sword Podcast, Dr. Lee Sharma and Heather Packer revisit the tragic 1992 murder of Rachel Nickell on Wimbledon Common. What began as a high-pressure investigation quickly became a textbook case of anchoring: police fixated on Colin Stagg, used questionable tactics to “prove” his guilt, and ignored clear evidence pointing to the real killer, Robert Napper.

They explore how the same cognitive trap operates in clinical reasoning, workplace conflict, and everyday assumptions — and how curiosity, humility, and the SPARK framework can help us break free.

Three Actionable Takeaways:

• Recognize When You’re Anchoring: The moment you think “This is obviously the diagnosis / this person is the problem,” pause. Ask: “What evidence supports this? What contradicts it? What else could explain this?”

• Actively Seek Disconfirming Evidence: Force yourself (or your team) to look for information that challenges your initial theory. In medicine, always consider the “can’t-miss” diagnosis. In conflict or investigations, ask “What if we’re wrong?”

• Cultivate Curiosity and Humility: Stay open to being surprised. The best diagnosticians, investigators, and conflict navigators hold their first story lightly and remain willing to revise it when new evidence emerges.
