Learning to Fail Well

Thomas Edison, one of the most famous inventors in history, was not an overnight success.

Born in Ohio in 1847, his journey was defined far more by failure than by breakthrough. Take the light bulb—often credited to Edison, but in reality, an idea that already existed. The problem was not invention, but application. Early versions were impractical: too expensive, too fragile, or simply unable to last. In 1878, Edison set out to solve this.

What followed was not a moment of genius, but a process of relentless trial and error. Edison and his team tested thousands of materials for the filament. They explored at least three thousand different theories. Each attempt failed to produce a viable solution. Until one didn’t.

By 1879, Edison had identified a workable design and filament, creating the first practical incandescent light bulb.

But here’s the important part. Edison did not succeed despite failure. He succeeded because of it. Each failed attempt wasn’t wasted effort, it was information. A narrowing of possibilities. A step closer to clarity. This has powerful implications for schools.

When it comes to culture, we often search for certainty. The “right” system. The “perfect” approach. The strategy that will just work. And when something doesn’t land as expected, there can be a temptation to abandon it quickly or move on to the next idea. But culture doesn’t work like that.

Building culture is far closer to Edison’s process than it is to a quick win. It is iterative. It is imperfect. And at times, it will feel like things aren’t working.

A behaviour system may need refining. A routine may not land first time. A new expectation may be inconsistently applied. These are not signs of failure. They are part of the process.

The key difference lies in how those moments are treated:

• In weaker cultures, mistakes lead to abandonment: “That didn’t work, let’s try something else.”
• In stronger cultures, mistakes lead to refinement: “What did we learn, and how do we improve it?”

This is where many school improvement efforts falter. Not because the idea was wrong, but because it wasn’t given the time, consistency, and reflection needed to embed. Too often, schools move from initiative to initiative, never staying long enough to learn what works in their context.

Edison didn’t change the goal. He refined the approach. For school leaders, this raises an important challenge:

1.  Are we building a culture that avoids failure?
2.  Or one that learns from it?

Because the latter is where real improvement lives. Your “ideal” school culture is not discovered fully formed. It is built, iteration by iteration, refinement by refinement.

And every mistake, if properly understood, is not a step backwards…It is a step closer.
