Decision-Making Under Uncertainty

Why Decision-Making Is a Leadership Skill

Leaders make decisions constantly, often with incomplete information and under time pressure. The quality of decisions is a function not only of analytics, but also of the decision-making process.

Pitfalls in Decision-Making

Anchoring bias: the first information disproportionately influences the final decision. The initial price in negotiations anchors the result.

Sunk cost fallacy: we continue to invest in a failing project because we've already invested a lot. "We've already spent $10 million — we can't stop now."

Confirmation bias: seeking information that confirms a decision already made.

Groupthink: group pressure towards conformity, suppression of dissenting voices. NASA Challenger.

Overconfidence: overestimating the accuracy of one's forecasts and knowledge.

Tools for Quality Decisions

Pre-mortem (Gary Klein): before making a decision, imagine a year has passed and the project has failed. Why? What factors led to the failure? This helps identify risks ahead of time.

Devil's Advocate: assign someone to challenge every key assumption of the decision.

10-10-10 (Suzy Welch): how will you evaluate this decision in 10 minutes? 10 months? 10 years? Distance helps separate short-term from strategic perspectives.

Bayesian updating: start with a prior probability → get new data → update the assessment. Do not ignore base rates.

Speed vs Quality of Decisions

Amazon: "Most decisions are reversible — make them quickly. Irreversible ones — slowly and thoroughly." Many leaders spend the same amount of time on every decision — this is inefficient.

Practical Assignment

Recall an important decision you made in the past 6 months. Retrospectively: (1) Which cognitive pitfalls influenced the process? (2) Were all relevant viewpoints heard? (3) What do you know now that would have changed your decision? (4) How can you improve the decision-making process next time?
