The Taxonomy of
Structural Harm
Some systems harm you with a ruler
and call what it can't measure unreal.
Structural harm is often easiest to miss when the process producing it looks ordinary, neutral, or fair. The harm is not always a broken rule. Sometimes it is the rule, the threshold, the measurement, the record, the gate, or the judgment working exactly as designed.
This taxonomy names six recurring mechanisms so they can be distinguished, traced, and repaired instead of collapsed into a single diagnosis of a system being “broken.”
How structural harm
gets produced.
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 mechanisms can look similar from the outside. The distinction matters because each points to a different failure — and therefore a different repair. Try four cases built around the easiest pairs to confuse.
Which mechanism is this?
A worked
example.
One system, run through all six mechanisms. The point is not to find the one correct label. It is to see what becomes visible when the mechanisms are separated.
The means-tested safety net

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.
What this is
The Taxonomy of Structural Harm is a diagnostic vocabulary for distinguishing recurring ways institutions and systems can produce harm through processes that remain legible as ordinary, neutral, or fair.
Its purpose is specificity: to make different mechanisms visible enough that they can be analyzed separately rather than treated as one undifferentiated failure.
Start with the mechanism.
Ask what the system cannot measure, where it creates discontinuities, whether hardship compounds, what labor disappears from the record, what entry requires, and whether equivalent acts receive equivalent judgment.
More than one mechanism can operate at once. The worked example above is designed to show how they can reinforce one another.
Name what you see.
