Occam’s Razor: Simplicity as a Signal of Complexity

The Farmer’s Fence

A rancher spent three weeks building a fence to keep his cows from wandering off. He measured every post, reinforced every joint, even added motion sensors to detect movement. But the cows still escaped - not all at once, just one at a time, as if mocking his effort.

Finally, in frustration, he called his neighbour- an old farmer known for fixing things nobody else could. The old man arrived with a coil of rope, a hammer, and a quiet smile. He watched the herd for a while, then walked to the far end of the field, where the fence met a gap by the creek. There, he closed a small side gate that opened into a greener patch of grass, tied it off with the rope, and walked back. “Try it now,” he said. The cows stayed put.

The rancher, puzzled, asked what he’d done. The farmer shrugged. “You built a fence to keep them in. I just closed the one door that made them want to leave.”

The story is funny - and a little humbling - because it exposes something universal. In business, as in life, we often equate sophistication with success. We assume that more structure, more data, and more tools will solve the problem. But most of the time, the real insight lies in understanding what’s already there.

The Weight of the Razor

Occam’s Razor - the idea that the simplest explanation is often the best one - isn’t an argument for laziness. It’s a test of understanding. To strip away what’s unnecessary, you first need to know what’s essential.

That’s what the old farmer had. His simplicity wasn’t luck; it was clarity earned through experience. He didn’t need complex fences because he understood the cows - their patterns, their instincts, their behaviour. His answer looked effortless because the work had already been done, quietly, beneath the surface.

It’s the same in markets, start-ups, or asset management. The most resilient ideas are rarely the ones wrapped in jargon or propped up by overly intricate models. They’re the ones that can be stated clearly, tested quickly, and defended simply.

Complexity might feel intelligent, but simplicity reveals truth.

Complexity as Camouflage

There’s a certain kind of comfort in complexity. Founders and fund managers often use it as a shield - against uncertainty, against scrutiny, against the discomfort of being wrong. The thicker the language, the safer the idea seems. A 50-page strategy deck feels more credible than a single slide that says, “Here’s what we do, and here’s why it works.”

But markets aren’t fooled. Complexity that hides weak reasoning doesn’t age well. It erodes alignment, slows decision-making, and ultimately reveals fragility. Whether it’s a fund bloated with derivative layers or a start-up chasing ten markets at once, complexity becomes a substitute for conviction.

Simplicity, by contrast, makes conviction visible. It narrows the space for excuses. When you say, “This is what we believe,” and you say it plainly, your reasoning stands in the open. It’s uncomfortable - but it’s also the only way to build trust.

When Restraint Becomes Strategy

Few modern companies have embodied this principle better than WhatsApp.

When Facebook acquired it for $19 billion, WhatsApp had fewer than 60 employees and one product: messaging. No games, no ads, no frills. In an age of “super apps,” it looked almost austere. But its founders, Jan Koum and Brian Acton, believed communication should be simple, secure, and universally accessible.

That restraint became their edge. Beneath the minimalist design lay some of the most complex engineering in consumer tech - efficient global servers, data-light infrastructure, end-to-end encryption. But users never saw the machinery. They just sent messages, and they worked.

That’s what real simplicity looks like: effort so refined that it disappears from view. The same principle applies to strong portfolios or durable business models. Simplicity is not the absence of sophistication - it’s the mastery of it.

The Discipline Behind Clarity

To make something simple is to make it accountable. When a thesis, strategy, or product can be expressed in one sentence, it exposes its logic to the world. If it’s weak, it breaks. If it’s strong, it compounds.

That’s why simplicity is a discipline, not an aesthetic. It forces choices:

• What matters most?

• What can be removed without loss?

• What’s true even when markets change?

• 
  

These questions demand rigor. They also demand humility - the willingness to admit what you don’t know, to pare back what’s uncertain, and to let your reasoning be transparent enough for others to test.

In both investing and management, that’s the real mark of maturity: to build systems so clear that others can hold you to them.

The Ethics of Simplicity

There’s a moral dimension to clarity that often goes unspoken. When you manage other people’s capital, time, or trust, simplicity isn’t a design choice - it’s a responsibility. Complexity that confuses stakeholders isn’t innovation; it’s obfuscation.

The duty, then, is not to impress but to inform. The investors who can explain risk in plain language are often the ones who understand it best. The founders who can describe their product in a sentence usually have the deepest sense of purpose. Simplicity, in this sense, is integrity made visible.

Back to the Fence

The rancher eventually replaced the sensors and reinforced beams with the farmer’s simple rope-and-latch fix. The fence looked less impressive, but it worked. Over time, he started applying the same thinking elsewhere - to his tools, his routines, even his hiring.

He didn’t stop caring about quality; he just stopped confusing effort with insight.

And that’s really the quiet power of Occam’s Razor. The simplest answer isn’t always right, but it’s the right place to start. It reveals how well you’ve understood the problem - or whether you’ve only been building fences in the wrong direction.

Because in the end, the cows were never trying to escape. They just wanted a clearer path home.

Simplicity doesn’t shrink complexity - it earns the right to command it.
