P2.2 - The Parsimony Law

Premise: Occam’s razor is not taste - it’s constraint. Minimal description length wins.

One-sentence version

If multiple explanations fit, the one with less unnecessary machinery is not just “nicer”; it is more stable under extension, prediction, and integration.

The Paper (Narrative)

Parsimony is usually introduced as a rule of thumb: “Don’t multiply entities beyond necessity.” That can sound subjective, like style preference.

But in science and engineering, parsimony behaves more like a survival filter:

  • Overfit models are fragile.
  • Baroque explanations break when you add new data.
  • Unnecessary parameters hide contradictions.

So the project treats parsimony as a constraint on what counts as a defensible ontology.

This matters because it tells you what kind of claims to expect from the rest of the system:

  • Not “it could be this, or that, or anything.”
  • But “given the constraints, the solution space collapses.”

Later, when the system argues for a terminal observer, a grace operator, or a specific set of boundary conditions, it is not trying to be maximalist. It is trying to be minimal while sufficient.

That is the parsimony law in plain language:

Reality may be deep, but it is not wasteful.

What This Paper Is Not Claiming

  • It is not claiming the simplest story is always true in every context.
  • It is not claiming we can measure Kolmogorov complexity perfectly (we cannot).
  • It is claiming that explanations that require infinite ad-hoc patches are not stable.
