The End of the Popularity Contest: Why Your 'Gut Feeling'Is a Terrible Way to Promote People

It is promotion season. You are sitting in a conference room with your leadership team. You have a list of names. You need to decide who becomes the new Team Lead.

Someone says, “What about Dave? He’s a great guy. Always stays late. The clients love him.”

Someone else says, “I don’t know about Dave. He seems a bit disorganized. What about Sarah? She’s sharp.”

And so it goes. You trade anecdotes. You rely on recency bias—remembering the one good thing Dave did last week and the one mistake Sarah made yesterday. You rely on proximity bias—favoring the people who sit closest to you.

Ultimately, you promote Dave because he “feels” ready. Six months later, Dave is drowning. The team is unhappy. And you are wondering where you went wrong.

This is how most companies make their most critical decisions. They rely on the “Gut Feeling.” But the gut is not a precision instrument. It is a bundle of biases wrapped in ego.

We need to stop guessing. We need to start measuring. We have more data on our employees than ever before, yet we rarely use it to make people decisions. We need to shift from the subjective “I think” to the objective “The data shows.”

The Halo Effect and the Horn Effect

To understand why we need data, we have to understand why our brains fail us. The “Halo Effect” occurs when we let one positive trait overshadow everything else. If an employee is charismatic and funny, we assume they are also competent and strategic. We promote the personality, not the skill set.

The “Horn Effect” is the opposite. If an employee is quiet or awkward, we assume they are disengaged or incompetent. We overlook their massive contributions because they don’t “look the part” of a leader.

These biases are expensive. They lead us to promote confident mediocrity while ignoring quiet excellence.

Data cuts through the Halo. It doesn’t care if Dave is funny. It cares if Dave completed his training modules. It cares if Dave’s code passed QA. It cares about the trend line of his performance over six months, not just the last two weeks.

Training Data as a Leading Indicator

Most performance metrics are lagging indicators. Sales numbers tell you what happened last quarter. Training data is a leading indicator. It tells you what will happen next quarter.

When you look at how an employee interacts with your learning systems, you see their trajectory. You see their curiosity. You see their grit.

Look at the “Completion Velocity.” Who finishes the optional training modules first? That person is hungry.

Look at the “Assessment Accuracy.” Who scores 100% on the first try versus who needs five tries? That tells you about attention to detail and comprehension.

Look at the “Peer Support” metrics. In a collaborative learning environment, who is answering questions for others? That person is a natural leader, even if they don’t have the title yet.

This data allows you to spot high potentials before they even hit their peak performance. It allows you to invest in the people who are investing in themselves.

The Skill Matrix

To make data-driven decisions, you need a framework. You need a Skill Matrix.

This is a simple grid. On one axis, you list the core competencies required for the role (e.g., Technical Writing, Conflict Resolution, Project Management). On the other axis, you list your employees.

Do not fill this grid with “Gut Feelings.” Fill it with evidence. Can Sarah demonstrate proficiency in Conflict Resolution? Has she completed the certification? Has she handled a documented dispute successfully?

If the box is green, it is because there is data to support it. If the box is red, it is a training gap.

When you look at the matrix, the promotion decision becomes obvious. You aren’t choosing between Dave and Sarah. You are choosing the person whose Skill Matrix matches the requirements of the new role.

“The role requires Level 3 Project Management. Dave is Level 1. Sarah is Level 3. Sarah gets the job.”

This removes the emotion. It removes the politics. It makes the decision defensible. If Dave asks why he didn’t get the job, you don’t have to give him a vague answer about “readiness.” You can show him the matrix. “You need to level up in these two boxes. Here is the training plan to get you there.”

Democratizing the Career Path

When you use data, you democratize opportunity. In a “Gut Feeling” culture, the only way to get ahead is to schmooze the boss. It favors extroverts and people who are good at office politics.

In a “Data-Driven” culture, the path to promotion is transparent. “If I complete these modules and demonstrate these skills, I will be eligible for the next level.”

This empowers the introverts. It empowers the remote workers who don’t get as much face time. It empowers diversity because the algorithm doesn’t care about your background; it cares about your output.

It changes the psychology of the team. They stop competing for your attention and start competing for competence.

The Danger of Metric Fixation

Of course, data has its own traps. If you only measure “Time Spent Learning,” you encourage people to leave videos running in the background. If you only measure “Quiz Scores,” you encourage memorization over understanding.

You have to measure the application of knowledge, not just the consumption of it.

This is where AI and modern platforms shine. We can now track “Skill Application.” Did the employee use the new sales technique on a call? (AI analysis of the call transcript can tell you). Did the developer use the new security protocol? (Code scanning can tell you).

We want to measure the behavior change, not the activity.

Building the Bench

The most strategic use of this data is succession planning. You shouldn’t be scrambling to find a replacement when a manager quits. You should know exactly who is ready to step up.

Your data should act as a “Depth Chart.” You should be able to see who is 80% ready for the next role. You should be able to see exactly which 20% of skills they are missing.

This allows you to be proactive. “Hey Mike, you are crushing it in your current role. Our data shows you are ready for leadership, but you need to shore up your financial literacy. Let’s get you into a course on P&L management so you are ready when the spot opens.”

This conversation builds immense loyalty. It shows Mike that you see his future. It shows him a clear path.

The Transition to Objectivity

Moving from subjective to objective people management is hard. It requires you to let go of your intuition. It requires you to trust the system.

But the cost of bad promotions is too high to ignore. A bad manager doesn’t just fail; they break the people underneath them. They cause churn. They destroy culture.

By using training data and skill matrices, you are building a safety net. You are ensuring that the people you promote have the actual tools to succeed, not just the personality to get the job.

Stop promoting the person you like. Promote the person who is ready.
