Pathway
The unintended consequences nobody planned for
When an action produces effects nobody planned for - sometimes bigger than the original move.
Every action in a connected system produces more than one effect. You planned for the first one - that’s the whole point. But the second and third effects travel through pathways you didn’t draw on the whiteboard. This isn’t a reason to stop acting. It’s a reason to widen your view before you do. This pathway helps you see where ripples are likely to travel - and which ones to watch.
The reason ripples travel at all. The parts of any system are connected - and those connections carry effects in every direction, not just the one you intended. The more connected a system is, the further and faster effects spread. Understanding what's connected to what is the first step in seeing where your ripple will go.
Core building blocks
Interconnections
The relationships between parts matter more than the parts themselves
Why the size of the ripple doesn't match the size of the action. In a nonlinear system, a small push can produce an enormous effect, and a large push can produce almost nothing. The relationship between cause and effect isn't proportional - which is why so many side effects catch people by surprise.
Core building blocks
Nonlinearity
Small changes can have huge effects, and big changes can have none - systems rarely respond in proportion
Where you drew the line around "the system" determines which ripples you see and which ones you miss. Most unexpected effects happen outside the boundary you set when planning. Widening the boundary before you act - asking "what else is connected to this?" - is one of the simplest ways to anticipate ripples.
Core building blocks
Boundaries
Where you draw the line around a system changes everything you see inside it
The direct result of interconnections, nonlinearity, and boundaries working together. Every intervention produces effects you didn't plan for. Some are harmless, some are beneficial, and some are bigger than the intended effect. The question isn't whether there will be unintended consequences - it's how to spot the ones that matter.
System behaviours and patterns
Unintended Consequences
Every intervention in a system produces effects you didn't plan for - sometimes bigger than the ones you did.
A sharper version of the same idea. This isn't just "things happened that we didn't expect" - it's the recognition that the intervention itself changed the system in ways that go beyond the problem it was designed to address. The act of intervening reshapes the terrain.
Leverage and intervention
Intervention Side Effects
Every action in a complex system produces effects beyond the one you intended
When ripples lead somewhere you can't easily get back from. Certain system configurations act like traps - easy to fall into, hard to climb out of. Recognising these patterns before your ripple reaches them is worth far more than trying to escape them afterwards.

System Traps
Predictable structural failures that show up across every kind of system
The hopeful counterpart. If small actions can produce large unintended effects, they can also produce large intended ones - if you know where to push. Leverage points are the places in a system where a well-aimed intervention has an outsized positive impact. The same interconnectedness that carries unwanted ripples can carry wanted ones.
