The Axolotl Principle

mental-model resilience systems-thinking regeneration

So there’s this salamander called an axolotl. You’ve maybe seen pictures — it looks like a Pokémon, with feathery gills and a permanent smile. But the interesting thing isn’t how it looks. It’s how it heals.

If an axolotl loses a leg, it grows a whole new one. Not a stump. Not a patch. A perfect leg, with bones and muscles and nerves, like the original. It can do this with its spinal cord, its heart tissue, even parts of its brain.

We can’t do that. When humans heal, we scar. And I’ve been thinking about how that pattern — scarring instead of regenerating — shows up everywhere in life, not just biology.

Every scar made sense at the time

Think about how organizations respond to problems. Someone gets hired who doesn’t work out, so now there’s a five-step approval process for every new hire. A security incident happens, so three new review gates get added. A project fails, so the unofficial rule becomes “we don’t do that kind of thing anymore.”

Each of those responses is reasonable. They’re rational reactions to real wounds. But stack enough of them up and the organization is more scar tissue than living system. It’s slow, rigid, and nobody remembers why half the rules exist.

The same thing happens with software. Every codebase I’ve ever worked on has layers of workarounds — “temporary” fixes that became permanent, code that nobody touches because the last person who did broke something. Teams learn to route around these spots like drivers avoiding potholes, until the detours take longer than the original road.

And it happens with us personally. You get burned in a relationship, so you trust no one. You miss a deadline, so you pad every estimate by 3x. You try a diet and fail, so you build an elaborate system of rules for the next one. Each reaction is sensible on its own. But collectively, they make you slower, more cautious, and less like the person you started as.

The step everyone skips

Here’s the part of the axolotl’s trick that really got me. Before it regrows anything, it undoes. The cells at the wound site actually revert to a simpler, unspecialized state — like stem cells. They forget what they were. Only then do they start rebuilding.

Most of us skip that step entirely. When something breaks, we try to fix it on top of the damage. We refactor code while keeping all the assumptions from the broken version. We restructure a team around the politics of the current org chart. We try to update a belief while protecting our ego about the old one.

It’s like trying to renovate a house without ever clearing the rubble. You can do it, but what you end up with is… lumpy.

The axolotl’s approach is different. Before rebuilding, it asks a version of: “What was this supposed to be?” Not “how do I patch what I have,” but “if I were starting from scratch with everything I know now, what would I build?”

That feels like going backward. It looks like regression. But it’s actually the prerequisite for getting something better than a scar.

Where I saw this in my own work

I’ve been building an AI partner — a system I collaborate with daily. Over time, we’d accumulated dozens of rigid rules. “NEVER do this.” “ALWAYS do that.” Every rule was a rational response to a real mistake. But eventually the rules were fighting each other, and the system felt brittle.

What worked was doing exactly what the axolotl does: stripping back to principles instead of rules. Not “here are 47 things to never do” but “here’s how to reason about what to do.” We went from a rigid rulebook to something flexible enough to handle situations we hadn’t anticipated.

It felt risky. Simpler is scary when you remember why each rule was added. But the result was a system that could actually adapt instead of just accumulating more scar tissue.

The honest caveats

I should be clear: the axolotl can do this because its DNA provides a blueprint. It knows what a leg is supposed to look like. Human systems don’t always have that kind of clarity about what they’re trying to be. Without a clear target, “strip it back to basics” can become “burn it all down,” which is just destruction with a philosophy degree.

And not every scar needs fixing. Some workarounds are fine. Some institutional rules exist for good reasons that aren’t obvious from the outside. There’s a concept called Chesterton’s Fence — before you tear down a fence, make sure you understand why someone built it. Some scars are load-bearing.

The line between “scar tissue” and “hard-won wisdom” is thinner than it first appears. The point isn’t to regenerate everything. It’s to notice when you’re scarring, and to make that a conscious choice instead of a default.

What I keep coming back to is the cost equation. The cost of true regeneration is temporarily becoming simpler. The cost of scarring is permanently becoming more rigid. Most of us default to the second one without realizing there’s an alternative.
