Leaders Who Don't Teach Are Losing Ground They Don't Know They've Ceded
Richard Feynman believed you don’t actually understand something until you can teach it. Not present it, not summarize it, not delegate a slide deck about it. Teach it, to someone who will ask questions you haven’t scripted and push back where your reasoning gets soft. His method was a forcing function for genuine comprehension, and it worked because the act of teaching surfaces exactly what you don’t know.
Most senior leaders today are not teaching. They are approving, deciding, and communicating. Those are different activities. They don’t carry the same epistemic burden, and they don’t produce the same organizational outcomes.
What Gets Lost When Leaders Stop Teaching
The first casualty is judgment. When a leader teaches, she externalizes her reasoning, which means her team can examine it, calibrate to it, and eventually extend it. When she only announces conclusions, the reasoning stays locked inside her head and the organization learns to wait for answers rather than develop the capacity to reach them. Over time, the bottleneck gets worse. The leader gets busier. The team gets less capable. Nobody identifies the root cause.
The second casualty is trust. People follow leaders they understand. Not leaders they like, not leaders they fear, but leaders whose thinking they have seen operate under pressure. Teaching creates those moments. A leader who walks through how she thinks about risk, or how she evaluates a vendor, or why she passed on a particular strategy, is giving her team something durable. She is building a mental model of leadership that people can internalize and apply when she is not in the room.
The third casualty is the leader herself. Feynman was right that teaching sharpens understanding. A CIO who cannot explain why her architecture decisions matter to someone in operations has probably not interrogated those decisions as hard as she should. The act of translation, of making complex thinking accessible without losing its integrity, is one of the best diagnostics available for the quality of your own reasoning.
Why Leaders Stopped Teaching
Part of this is structural. The pace of organizational life has compressed. Leaders are managing more surface area with flatter teams and faster cycles. Teaching feels like a luxury when the calendar is already a hostage situation. But that framing inverts the actual risk. Teaching is not a drain on capacity. It is how you build it.
Part of it is status anxiety. Teaching requires admitting what you are still working through, which feels incompatible with the version of executive presence many leaders have absorbed. That version confuses certainty with credibility. It produces leaders who perform confidence rather than demonstrate competence, and who regard questions as challenges to deflect rather than problems to engage.
Part of it is that the tools of communication have made broadcasting easy. Newsletters, recorded messages, all-hands decks. These formats create the sensation of transparency without requiring the discomfort of genuine intellectual exchange. They are one-directional and risk-free. They are also nearly useless for developing organizational capability.
What Teaching Actually Looks Like at the Executive Level
It does not require a curriculum or a scheduled session. It requires intention. A COO who takes thirty minutes during a post-mortem to walk through how he evaluated options, not just what he decided, is teaching. A CFO who brings a junior analyst into a board prep conversation and explains the logic behind how risk gets presented is teaching. A CIO who responds to a team disagreement by mapping out the underlying tradeoffs rather than issuing a resolution is teaching.
These moments compound. They create organizations where people understand not just what to do but why, which is the only reliable basis for good judgment when the situation is novel and there is no one to ask. Novel situations are the only situations that actually matter at the senior level. Everything else has a playbook.
The Strategic Argument
A leader who hoards her reasoning creates fragility. The organization depends on her presence for every non-routine decision. She becomes the single point of failure for judgment. If she leaves, takes a different scope, or is simply unavailable at the wrong moment, the institution has no reserve.
A leader who teaches creates leverage. Her thinking persists past any single conversation. It becomes part of how the organization reasons, which is among the most durable competitive advantages an institution can develop and one of the hardest for competitors to replicate.
Boards that are serious about succession should be asking not just who the next leader is, but what the current leader has actually transferred. The answer to that question is determined almost entirely by whether the leader was willing to teach.
