Judgement at Work summary

A single decision can alter the course of history. Take the Cold War, when a Soviet officer received an alarming report: the US was about to launch a missile attack – 100 percent certain. Standard procedure dictated he escalate the warning, potentially sparking nuclear war. But something felt off. The certainty was unusually high, with no additional verification. Trusting his gut over procedure, he identified a system malfunction. He was right. Disaster averted. Later, they confirmed that the alert was a false alarm, triggered by sunlight bouncing off cloud formations. His ability to question the data, draw on experience, and spot inconsistencies prevented a catastrophic response.

This officer’s judgment showcases the six key components of sound decision-making: experience, awareness, trust, information quality, emotional regulation, and reasoning ability. Each plays a role in effective decision-making but may also result in errors if misused. In this section we’ll focus on the first three – experience, awareness, and trust – which form the foundation of strong initial judgments.

Now that we’ve covered the foundations of sound judgment, let’s turn our attention to emotions and beliefs. They shape how we assess risk, interpret information, and make decisions. Some things that influence our beliefs, like personal values, are explicit. Others, such as biases formed through experience, operate unconsciously. These biases affect how we process information and form beliefs. 

Take availability bias. It makes us overvalue information that’s easy to remember. Recency bias, on the other hand, gives too much weight to what happened lately. And confirmation bias leads us to favor information that aligns with our preexisting beliefs – dismissing what contradicts it. Overconfidence is another trap, making us believe our judgment is more reliable than it actually is. 

When it comes to good judgment, how do you know when to trust your instincts, when to take a risk, and when to step back and evaluate? Understanding risk, timing, and the limits of intuition is essential for good decision-making.

Let’s start with risk. It should neither be ignored nor taken without thoughtful consideration. Why? Because small choices can build into major failures, as seen in structural collapses or financial disasters. Because risk is often unclear, people tend to follow instinct over probability, and organizations struggle to balance caution with ambition. The most effective decision-makers don’t shy away from risk; they approach it proactively, combining analysis with experience.

We've explored the components of good judgment – experience, awareness, trust, emotional regulation, and how speed and risk affect decision-making. Now, let's examine how these principles play out in specific leadership contexts, where the stakes and challenges vary significantly.

At the executive level, judgment takes on a distinctive character. Unlike routine decisions handled at lower organizational tiers, the challenges that reach senior leaders involve competing interests, unpredictable outcomes, and significant risks. Good judgment at this level means balancing experience with awareness of blind spots, managing emotional responses, and knowing when to act quickly versus when to deliberate. Those who excel understand that judgment must be applied with even greater discipline when the consequences affect entire organizations.
