One Data Point Is Dangerous

Why wise leaders seek perspective before making major decisions

This is the second article of a three-part series investigating how intentional leaders pursue clarity while the more typical and average leader may pursue comfort.  Today, we uncover how leaders look deeper than a single data point, and even what matters when it comes to reviewing data.

As an engineer, one of the most valuable lessons I learned was understanding data points. Every set of data has a low, a high, and an average. Of course more data is always valuable, the simple point is that with fewer than three meaningful data points, it becomes difficult to truly understand what is happening.

Leadership works much the same way. Too many leaders make assumptions based on limited information. They listen to one perspective. One complaint. One opinion. One emotional reaction. Then they conclude they understand the problem.

One of the greatest advantages of being trained as an engineer is that you learn to respect data. Not emotions. Not assumptions.Not isolated opinions. Data. You learn quickly that one data point rarely tells the full story.  Every meaningful measurement has a range:

• a low,

• a high,

• and an average.

With fewer than three meaningful data points, it becomes difficult to truly understand what is happening. Without enough information, it becomes difficult to determine what is truly happening. In fact, with only one or two data points, people often mistake emotion for evidence and assumptions for wisdom.

That lesson applies far beyond engineering. It applies directly to leadership. It applies to business. And it certainly applies to major life decisions.

Looking back, one of the riskiest decisions I ever made was leaving a salaried job to pursue entrepreneurship. At the time, one of the strongest data points influencing my decision was the growth of my savings and investment portfolio. Another was the encouragement of a financial representative who believed I had positioned myself well enough to take the risk.

Those conversations mattered. That encouragement mattered. And ultimately, I made the leap. I moved from a job to freedom - that was in 2021.

The next year, 2022, the financial markets tumbled.  The Dow dropped 9%, the S&P 500 fell 20% and the NASDAQ went down 33%.  My retirement portfolio dropped 39%.  Here’s the key to investing (as well as leadership), know why you are investing (leading).  And when there’s a drop in your portfolio (a leadership struggle), and lean into your reasons, your training, your experience and lead yourself and your team regardless.

Looking back now, I can honestly say it was one of the riskiest decisions I ever made — and also, one of the best decisions I ever made. Hindsight also taught me something important:  One data point is dangerous.  I could have said, dropping that much in my retirement savings and moving to an entrepreneurial role was too much risk.  But I didn’t.  Why?  Because that is really one data point.  

At the time, I believed I had enough perspective. In reality, I was operating with limited visibility. Thankfully, the decision worked out well, but wisdom later taught me that successful outcomes do not automatically validate incomplete decision-making processes. Sometimes people make poor decisions and get lucky. Other times people make wise decisions and still face difficulty. That is why mature leadership requires more than isolated evidence or emotional confidence. Wise leaders do not build major decisions on limited perspective.

Yes, my retirement savings dropped; and yes, it was worse than some of the major indexes.  There were other data points I should consider.  

• How does my portfolio typically perform compared to these major indices (am I consistently behind)?  No

• Am I nervous about this market downturn? Not really, I’m comfortable that I am invested in some focus areas.

• Should I investigate any other investment strategies?  Yes  

Too many leaders operate from narrow inputs:

• one opinion,

• one encouraging conversation,

• one disappointing experience,

• one successful quarter,

• one negative employee,

• or one emotional reaction.

Then they make sweeping decisions based on incomplete information. The danger is not simply bad decisions. The danger is false confidence. A single data point may reinforce what we already want to believe or it may scare us from evaluating what our original thesis was.

That is why wise leaders intentionally widen perspective. They ask:

• What am I missing?

• Who sees this differently?

• Is my original approach all wrong now?

• What additional information do I need?

• Is this a pattern or simply an isolated event?

• Am I reacting emotionally or evaluating strategically?

Those questions create discernment. And discernment is one of the most valuable leadership disciplines a person can develop. I have seen leaders become overly optimistic based on one success and overly discouraged based on one setback. Neither response is healthy. Strong leadership requires perspective over time.

In business, I have watched organizations make major culture decisions based on one complaint rather than broader patterns. I have also seen leaders ignore significant warning signs because one trusted voice reassured them everything was fine. Both situations create unnecessary risk. Emotion without perspective creates instability. Perspective creates wisdom.

That principle also changed the way I think about investing.

Over the years, I learned that successful investors seek patterns, trends, and long-term positioning rather than reacting emotionally to daily volatility. One of the valuable lessons I learned was that concentrated focus often produces stronger long-term outcomes than scattered attention. In leadership, the same principle applies. Wise leaders do not chase every opinion, every criticism, or every trend. They evaluate carefully. They gather perspective. They identify patterns. Then they move decisively.

That process requires patience. And patience can feel uncomfortable in a world that rewards immediate reactions. But leadership maturity often means slowing down long enough to see clearly before moving quickly.

One of the reasons many leaders struggle with discernment is because gathering additional perspective requires humility. It requires admitting:  “I may not yet have enough information.” That can be difficult for high-capacity leaders. But humility protects leaders from the danger of limited vision.

The longer I lead, the more I realize that wisdom is rarely found in extremes. It is often found in carefully evaluating multiple perspectives before making major decisions. One data point may inspire action. But sustainable leadership requires broader discernment.

Reflection Questions

• Am I making decisions based on emotion or sufficient perspective?

• Do I have an appropriate amount of real data to make a decision?

• Do I really need more data, or am I simply afraid?

  • If I am afraid, what’s the worst that could happen?

  • Is the worst tolerable or at least manageable?

  • What is the best that could happen?

  • What is the probability that the worst/best outcomes may happen?

• Where might I be overreacting to one success or one setback?

• Who do I need to listen to before making my next major decision?

• Am I seeking validation or seeking clarity?

Closing Thought

Wise leaders widen perspective before making major decisions because one data point is dangerous.
