THE FOUR FRICTIONS, PART 1

A knowledge gap is the one friction training can actually fix. The trouble is that most other frictions get mistaken for it, and training makes those worse.

When a transformation stalls, the reflex response is almost automatic: run more training. It feels right, it is easy to resource, and it signals action. Sometimes it works. Often it does nothing at all, and occasionally it makes things worse. The difference comes down to one question most organizations never stop to ask: is this actually a knowledge gap, or something that only looks like one?

A genuine knowledge gap is specific. People understand what the change is, they want to do it, and nothing in their environment is stopping them. They simply do not yet have the skill or information to perform the new way of working. This is the one kind of friction that training is designed to solve. When it is the real problem, teaching people how is exactly right.

Even real knowledge gaps resist the obvious fix

Here is the first uncomfortable finding: even when the problem genuinely is a knowledge gap, conventional training closes it far less often than leaders assume. The foundational research on this, Baldwin and Ford's model of training transfer, established that a large share of what people learn in formal training never shows up in how they actually do their jobs (Baldwin & Ford, transfer-of-training research).

The decay is steep and well documented. In Saks's peer-reviewed research on training activities and transfer, the share of trained skills still being applied fell from roughly 62% immediately after training to about 44% at six months, and lower still a year out (Saks, Human Resource Management (Wiley)). A completion certificate says a course was finished. It says nothing about whether behavior changed, and the gap between the two widens the longer you wait to look.

Training is the right tool for a knowledge gap. It is the wrong tool for every other kind.

The expensive mistake: treating every friction as a knowledge gap

The deeper problem is diagnostic. Training is the default intervention precisely because it is the easiest to deploy, so organizations reach for it regardless of what is actually blocking the change. When the real friction is something else, a lack of clarity about the goal, a threat to how people see themselves, or an attachment to the old way, more training does not help. It adds load, signals that leadership has misread the room, and burns credibility that the next intervention will need.

This is why diagnosis has to come before prescription. If people cannot articulate the goal, that is a clarity problem, and teaching them a skill they do not yet see the point of is wasted. If they feel the change threatens their competence or status, more instruction can deepen the threat rather than relieve it. If they are holding on to a familiar way of working, a course on the new one does not touch the reason they are holding on. Each of these looks, from a distance, like people not knowing how. None of them is.

How to tell a knowledge gap from its imposters

A real knowledge gap has a signature you can check for. Ask whether people can explain what they are being asked to do and why it matters: if they can, clarity is not the issue. Ask whether they want to do it: if the willingness is there, you are not looking at a threat or a refusal. Ask whether anything in the workflow, the incentives, or the tools is blocking them: if the path is clear, the gap is genuinely about capability. Only when understanding, willingness, and a clear path are all present, and performance still lags, are you looking at a true knowledge gap, the kind training can close.

That test matters because the four frictions each demand the opposite response. Misread which one you face and the intervention does not just miss. It can actively set the transformation back, because you have spent money, time, and goodwill treating the wrong disease.

Fixing the knowledge gap you actually have

When the gap is real, the research also points to what makes training stick: repetition over time rather than a single event, practice in the actual context of the work, and reinforcement after the classroom rather than before it. A one-time session near a launch is almost designed to decay. Capability builds when the new skill is rehearsed in the flow of real work and supported until it becomes automatic.

But none of that is worth doing until you are certain the knowledge gap is what you are facing. The most important move in closing a knowledge gap is confirming it is one. Diagnose the friction first. Then, and only then, teach people how.
