# MonoModularity

A body plan in which one model processes every situation, treating each situation as just more data for the same process

Layer: Mind · Category: Strategy

## Mechanism

A single model, algorithm or decision procedure is applied across all the environments it meets, and the particulars of each problem enter only as input data: one Bayesian update rule for every inference, one language model for every topic, one decision-maker freezing one plan at one moment. Because processing is uniform it scales well and pairs well with standardised lower-level parallel hardware. But it has little room to take in genuinely new information: changing how anything is done means changing the whole model at once, and systematic errors in the model are not corrected by feeding it fresh data. By the No Free Lunch theorems, no single model beats specialists across all problem classes.

## Invariants

- The same model is used regardless of domain; domains differ only as data
- A systematic error in the model is not corrected by updating its inputs
- Gains on one class of problems are offset by losses on another (No Free Lunch)

## Failure modes

- Applying the model far outside the conditions it was built for, so its error grows with use
- Mistaking a hierarchy of data types for a meta-model of the domain
- Correcting the model with the same perspective that produced its errors
