Mandatory Minimum Sentences is fixed sentencing rules remove judicial discretion and inflate incarceration without reducing crime. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0174, within the Law Perverse Pattern family. The core principle: fixed sentencing rules remove judicial discretion and inflate incarceration without reducing crime. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Original analysis from The Incentives Lab — how this element behaves inside real payoff structures.
Why this element matters to incentive design
The mistake with this element is treating it as irrationality. It is almost always a rational response to a payoff nobody wrote down. The mechanism underneath it is straightforward: fixed sentencing rules remove judicial discretion and inflate incarceration without reducing crime. You can recognize it in the field by its signature: flatten the curve of justice and you flatten the justice. Every element in the Incentives dimension changes the perceived payoff of an action before the action happens, which is exactly where incentive design has leverage.
How it gets exploited
Left undesigned, rigid rules outperform politicians' courage to revise them. It is amplified whenever rigid rules outperform politicians' courage to revise them. Inside organizations that shows up as rigid rules outperform politicians' courage to revise them. The pattern is the same one Goodhart's Law describes: the measurable proxy attracts the effort, and the purpose behind it quietly loses funding.
How the Lab designs around it
The redesign move is to judicial discretion. Sunset clauses. Outcome review. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
