THE IDEA
Past the point of no return
A car approaches a cliff edge in fog. The driver can’t see the drop until they’re almost on top of it. If they’re going slowly, they stop in time. If they’re going fast, they see the edge, hit the brakes - and go over anyway. The speed carried them past the point where stopping was possible. That’s overshoot: moving past a limit before you know you’ve reached it.
Overshoot and Collapse is what happens when a growing system exceeds the carrying capacity of its environment - and by the time the feedback arrives, the damage is too severe to recover from. It’s different from Limits to Growth, where growth simply slows and plateaus. In overshoot, growth doesn’t just slow. The system’s behaviour degrades the resource it depends on, and the collapse that follows takes the system to a state far worse than where it started.
The pattern requires two things: rapid growth and delayed feedback. If the feedback is fast - if the system gets an immediate signal that it’s approaching a limit - it can slow down and settle at a sustainable level. But when the signal is delayed, the system keeps growing past the sustainable point. By the time the consequences are visible, the resource has been damaged, sometimes beyond repair. Overshoot isn’t a failure to respond. It’s a failure that arrives too late for any response to matter.
IN PRACTICE
The boom that ate its own foundation
Easter Island is the most cited example, and it’s haunting. A small Polynesian population arrived on a richly forested island. The population grew. Trees were cut for canoes, fuel, and to clear land for farming. The forest shrank, but slowly enough that no generation saw a dramatic change. By the time the forest was gone, the soil had eroded, the canoes couldn’t be built, fishing became impossible, and the population collapsed. The islanders didn’t ignore the problem. The problem was invisible until it was irreversible. The delay between deforestation and its consequences spanned generations.
The 2008 housing bubble followed the same structural pattern. Lending grew exponentially. House prices rose. Rising prices made lending seem safe, which fuelled more lending. The feedback signal - that the underlying mortgages were unsustainable - was buried under layers of financial engineering that obscured the risk. By the time the defaults started, the financial system had overshot so far beyond what was sustainable that the correction wasn’t a gentle slowdown. It was a global crash.
Antibiotic resistance is overshoot happening in slow motion. The widespread use of antibiotics drives the growth of resistant bacteria. The feedback - infections that don’t respond to treatment - arrives years or decades later. By the time the medical system sees the consequences clearly, the resistant strains have already spread. We overshot the sustainable use of antibiotics, and the correction is arriving as a growing inability to treat common infections. The resource (antibiotic effectiveness) was depleted faster than anyone tracked.
WORKING WITH THIS
Slow down before you have to
The only reliable way to prevent overshoot is to respect limits before you hit them. That means tracking the resource, not just the growth. If you’re only measuring how fast something is growing without monitoring the thing it depends on, you’re driving in fog.
Build early warning systems. Overshoot happens because the feedback arrives too late. Anything that shortens the delay - more frequent measurement, leading indicators, scenario modelling - gives the system a chance to slow down before it overshoots. The goal is to see the cliff before you’re on the edge.
Be especially cautious when growth is rapid and the resource is slow to replenish. Fast growth plus slow recovery is the recipe for overshoot. A forest that takes a century to regrow, a team’s trust that takes years to rebuild, a reputation that takes a career to earn - these are all slow stocks. If the flows draining them are fast, the conditions for overshoot are in place.
THE INSIGHT
Speed kills systems too
Overshoot isn’t caused by bad intentions. It’s caused by fast growth and slow feedback. By the time you can see you’ve gone too far, going back may no longer be an option.
RECOGNITION
Knowing it when you see it
You’re at risk of overshoot when something is growing rapidly and nobody is tracking the resource it depends on. When the success metrics are all about growth but nobody is measuring the foundation that growth stands on. When people say “we’ve never had a problem before” about a resource that’s being consumed faster than it’s being replenished. When the correction, when it finally comes, is dramatically out of proportion to what anyone expected - that’s the signature of a system that overshot its limits.
