# Aesthetics

Optimization for human subjective preference

Layer: Infrastructure · Category: Data Structures

## Mechanism

A scalar [Metric](https://mindscape.pages.dev/bootstrap/Metric.md) representing the fit between an [Artifact](https://mindscape.pages.dev/bootstrap/Artifact.md) and the subjective preference priors of a human observer (e.g., harmony, [Parsimony](https://mindscape.pages.dev/bootstrap/Parsimony.md), style). Used to optimize solutions for social acceptance when functional utility is equal.

## Invariants

- Names the `axis` it scores.
- Carries the `normalized_range` the score is expressed in.
- Measures observer preference, not [Artifact](https://mindscape.pages.dev/bootstrap/Artifact.md) quality.

## Failure modes

- Objectivity mistake: a preference score is read as a quality measurement.
- Prior mismatch: the observer whose priors were modelled is not the observer being served.
