The Taxonomy of Structural Harm
More often than not, harm is structural. It doesn't have a face, a name, or a place to lay the blame. Harm is commonly built into how a system counts, judges, admits, and records, running through fair-looking process and leaving no one obviously at fault.
Each of the six is a mechanism, not a metaphor. Each carries a diagnostic question you can put to a real system, a place to look, and a tell that gives it away. Several sit one wrong diagnosis away from another, and the wrong call sends the repair in the wrong direction, so telling them apart is the first real move.
None of this requires bad intent. A system staffed entirely by decent people applying reasonable rules produces every one of these harms, because the harm lives in the structure and not in the operators.
The six mechanisms
Six ways a system produces harm through fair-looking process. Hover a tile — or tap on a phone — to turn it over.
Which one is it?
The taxonomy earns its keep when you can name the mechanism under pressure. Read the case, choose, and see what divides it from its nearest look-alike.
Which mechanism is this?
A worked example
One system, run through all six. The means-tested safety net in the United States, chosen because every mechanism lands on something concrete and because it is administered largely by people trying to help.

All six run at once, and they reinforce each other. The ruler keeps the trap invisible, because the compounding damage sits in exactly the dimensions the metric can't see. The door makes the cliff worse, because the difficulty of getting back in raises the cost of ever falling out. A reform that softens the cliff but leaves the ruler in place will report success while the trap keeps running underneath.
That is the case for naming them separately. A single word like "broken" collapses six mechanisms into one complaint, and each one has a different repair. The cliff needs a taper. The ledger needs an entry. The scale needs recalibration. Diagnose the wrong one and the intervention misses.
About
Part of Toward Reconstitution, a project on the structural omission of care and accountability from the systems that govern ordinary life.
A companion to the Answerability Index. Where the Index asks how a system organizes its functions, the Taxonomy names how those functions fail without anyone appearing to fail.
How to use it
Hold each diagnostic question against a system you actually deal with. Ask what its unit of account cannot see, where improving your position costs you, whether being in trouble generates more of it, what unlogged labor holds it up, whether entry requires prior entry, and whether identical acts get judged by who performed them.
The point is precision. The mechanisms look alike from a distance and demand different repairs up close.
