August 5, 1997. A routine overnight flight leaves Seoul airport. Families slept beneath the dim cabin lights. Honeymooners headed for vacation. Flight attendants moved quietly through the aisles collecting empty cups while the Boeing 747 crossed the Pacific through the darkness.
Up front, inside the cockpit, three very experienced crew members guided Korean Air Flight 801 towards the destination – Guam.
The descent begins.
01.39 AM: Rain battered the aircraft as the runway disappeared behind clouds and tropical storm weather. The captain continued the approach.
The first officer sounded uneasy. He sensed something was wrong. “The weather radar is helping a lot …”, he said.
Not a warning, not an objection. Just a carefully worded hint. A cautious sentence that is indirect and softened.
The aircraft descended lower.
01.40 AM: Inside the cockpit, tension quietly thickened. Altitude falling, rain intensifying. The ground proximity system had not yet screamed. The flight engineer glanced at the instruments and said, “Captain, don’t you think the rain is getting heavier?”
Again, softened language. Indirect, careful, and respectful.
The glide scope system that normally guided aircraft safely down to the runway was unavailable that night. The crew now had to rely on a more difficult approach in poor visibility.
But nobody said “we’re too low”, or “abort the landing”, or even “pull up immediately”.
01.41 AM: The captain continued the approach. The first officer noticed another dangerous descent. “Captain, the minimums …”, he says with the sentence trailing into silence.
No one challenged the captain directly. No one took control. The airplane continued descending through the darkness toward terrain hidden by rain.
01.42 AM: Ground alarms finally sounded, but it was too late.
Seconds later, Korean Air Flight 801 slammed into Nimtiz Hill, just short of Guam’s runway.
229 people died. Without even being able to scream a word. It just took a fraction of second for majority of the passengers inside the Boeing plane to take their last breath.
The investigation revealed weather, fatigue, procedural failures, and pilot errors as the major cause of the crash. But something that is mentioned in the report stands out. It reads:
“National Transportation Safety Board determines that the probable cause of accident was captain’s failure to adequately brief and execute the non-precision approach and the first officer’s and flight engineer’s failure to effectively monitor and cross check the captain’s execution of the approach.”

The Excessive Certainty
Most people think disasters are caused by ignorance. Many are actually caused by confidence. Not the regular confidence itself – but overprecision: the dangerous belief that your judgement is unquestionably correct.
Psychologists use the term overprecision to describe excessive certainty in the accuracy of our beliefs. It is why leaders stop listening, experts dismiss warnings, and powerful people slowly become insulated from contradiction.
Overprecision is overconfidence in the accuracy of one’s beliefs. This excessive certainty is on display when we are too sure we are right, when we believe we can forecast others’ behavior, when doctors are too certain of a favored diagnosis, or when managers issue excessively precise and inaccurate earnings forecasts. And because overprecision creates an exaggerated illusion of control and knowledge, it consistently impairs judgment, fuels confirmation bias, and makes individuals and professionals dangerously confident in their flawed intuitions.
Why Successful People Become Harder to Correct
The more successful someone becomes, the fewer honest reactions they receive.
At first, feedback is natural. A young founder gets challenged constantly. A junior employee gets corrected every day. A new manager still feels uncertain enough to listen. But success changes the social atmosphere around a person. People begin filtering themselves, criticism becomes softer, disagreement becomes diplomatic, and warnings become suggestions.
Not necessarily because others are weak but because humans instinctively avoid confrontation with authority. Especially when that authority appears confident. Over time, highly successful people stop receiving raw information. They receive curated information.
And that is dangerous. Because reality does not care how confident you sound.
Malcolm Gladwell devoted a chapter called “The Ethic Theory of Plane Crashes” in his book Outliers where his central argument as that the Korean Air Flight 801 crash was influenced not just by weather or pilot error, but by Korean cultural hierarchy inside the cockpit.
His argument was not that Korean pilots were less skilled. It was that extreme respect for authority made it harder for junior crew members to challenge a superior directly, even when they sensed danger.
Linguists call this “mitigated speech”, communicating a dangerous truth in softened, indirect, or overly polite language.
In normal life, mitigation keeps society civil. We say “Maybe you should slow down” instead of “You’re driving dangerously.” We say “I’m not sure that’s the best idea” instead of “This will fail.” But in environments where mistakes are fatal, softened language can become deadly.
Instead of “This strategy is failing”, people say “Maybe we should reconsider a few parts”. Instead of “You are making a mistake”, people say “I’m not too sure this is the best decision”.
The problem is not politeness itself. Civilization depends on softened language. The problem begins when clarity becomes weaker than hierarchy. In high-stakes environments, indirect communication can become catastrophic.
Thus, the more authority a person has, the less likely people are to speak honestly around them. And without accurate information, you’re just being too sure around the wrong item.
Ego: Silencing Dissents and Creating Organizational Blindness
Every failing organization eventually develops the same invisible problem: people stop telling the truth upward. Meetings begin to feel like performances rather than exchanges of honest thinking. Leaders hear increasingly polished versions of reality, where bad news is delayed, softened, or filtered out entirely. Risks remain unspoken until they escalate into crises. This does not happen because employees are unintelligent or careless, but because the system gradually begins to punish contradiction.
Over time, people learn that speaking too directly can carry social or professional costs, and so they adapt by becoming more careful, more indirect, and often more silent.
This process is closely tied to ego, though not always in the obvious sense of arrogance or dominance. Ego is often more subtle: it is the inability to seriously entertain the possibility of being wrong. Many of the most influential and successful leaders are not loud or dismissive; they are calm, intelligent, and highly competent. Their vulnerability lies in becoming psychologically identified with correctness itself.
Once that happens, disagreement no longer feels like useful input, it feels like a challenge to status or judgment. Criticism begins to register as disloyalty, and opposing views feel emotionally charged rather than analytically valuable.
In such environments, human communication naturally adapts. People around the leader begin filtering their speech, often without being explicitly told to do so. Supportive information is expressed clearly, while contradictory information is softened or reframed to reduce friction. Concerns become suggestions, warnings become cautious hints, and in some cases, silence becomes the safest option. What is especially dangerous is that this filtering is often misread by leadership as alignment.
In reality, it is withdrawal. As dissent disappears, so does the organization’s ability to correct itself. Learning slows, weak assumptions persist, and confidence compounds faster than correction. Eventually, the organization becomes increasingly detached from reality, not because it stopped seeing information, but because it stopped receiving it in its honest form.
Why Smartest Leaders Build Systems that Challenges them
The best leaders are not the ones who are always right. They are the ones who remain correctable. Strong leadership is not defined by the ability to project certainty at all times, but by the ability to create environments where truth can survive hierarchy.
That requires deliberate systems: teams that are able to openly disagree without fear, cultures where juniors can challenge seniors without hesitation, meetings where criticism is treated as useful information rather than disruption, and decision-making processes that clearly separate ideas from personal ego.
The most effective leaders understand something deeply uncomfortable: if nobody challenges you anymore, you are probably becoming dangerous. Silence around leadership is rarely a sign of alignment; more often, it is a sign that people have learned to withhold discomforting truths.
This is why high-reliability industries, especially aviation, have spent decades redesigning cockpit culture. After accidents like Korean Air Flight 801, the focus was not only on technical training but on communication itself. Captains were trained not just to lead, but to invite correction, while junior crew members were trained to speak clearly and assertively even in the presence of authority. The goal was simple but difficult: ensure that hierarchy never becomes a barrier to clarity.
Because when authority becomes impossible to question, small errors stop being small. They accumulate silently, reinforced by silence, until they become irreversible. And this pattern is not unique to aviation. It appears wherever confidence outruns correction: a founder ignoring engineers who see flaws in the product, a government dismissing analysts who warn of unintended consequences, a doctor overlooking concerns raised by nurses, a parent refusing to hear feedback from children, or a manager discounting insights from junior employees. In each case, the structure is different, but the dynamic is the same.
Confidence rises. Feedback weakens. Reality waits patiently. Until one day, the mountain appears through the clouds.
