Epistemic Trust Calibration
“Don’t confuse the finger pointing at the moon for the moon itself.”
A lightweight framework for calibrating how much trust representations deserve in a given context
Most of the tools we use to think are not the things we’re thinking about. Models, metrics, explanations, summaries, analogies, expert opinions—these are representations. They point at something in the world, but they are not the thing itself.
This idea isn’t new. It shows up in philosophy, engineering, science, and everyday wisdom. The problem isn’t that we’ve forgotten it. The problem is that modern decision-making routinely asks representations to carry more epistemic weight than they can support.
- confidence outruns evidence
- metrics become targets
- analogies harden into authorities
- uncertainty gets laundered into certainty
- disagreements become moral instead of structural
These failures aren’t about intelligence or intent. They’re structural. They emerge whenever representations are treated as if they are reality rather than tools for navigating it.
The core tension
There is no ambiguity-free medium. Language is ambiguous. Measurement is ambiguous. Models are ambiguous. Even explanations of ambiguity are ambiguous.
Because of this, trust is unavoidable. Certainty is impossible. Judgment has to enter somewhere.
The real problem isn’t trust. It’s implicit, total, and irreversible trust—trust that accumulates without anyone noticing, scoping it, or reconsenting to it.
Most systems don’t fail because they trusted the wrong thing. They fail because trust was never made explicit, bounded, or revisable.
What this framework is about
This project is a lightweight framework for calibrating how much trust representations deserve in a given context. It does not decide truth. It does not enforce correctness. It does not eliminate uncertainty. It does not replace human judgment.
Instead, it structures questions like:
- What is this representation being used for right now?
- What assumptions does it rely on?
- What kinds of ambiguity are present?
- Where does its reliability stop?
- How much reliance is appropriate given the stakes?
- Where does judgment have to take over?
The goal is not agreement. The goal is visible constraints.
Ambiguity isn’t a bug
A core move in the framework is to stop arguing inside ambiguity and instead name what kind of ambiguity is present. Typing ambiguity doesn’t resolve it. It localizes it.
- Semantic ambiguity: unclear or shifting meaning
- Contextual ambiguity: use outside the original context
- Mapping ambiguity: weak or unstable relationship to reality
- Structural ambiguity: limits imposed by simplification
- Normative ambiguity: unresolved or conflicting values
Trust, confidence, and judgment
This matters especially in AI-adjacent systems, where fluent outputs can quietly accumulate authority—and where humans often over-trust representations because they feel precise or confident.
A small example
A metric may be designed to explore trends or surface signals. Later, the same metric gets used to justify a decision.
Nothing about the metric changed—only the amount of reliance placed on it.
This framework exists to make that shift visible—so the decision doesn’t inherit a false sense of inevitability.
Why this exists as a public repo
I don’t have the time or resources to “build” this into a product. That’s not the point. The repo is a blueprint: a scaffold of constraints and concepts others can adapt, fork, critique, or ignore.
“We’re trusting this more than we realize.”
A final note
This framework doesn’t tell you what to believe. It doesn’t promise better decisions. It doesn’t offer certainty. It simply tries to make sure we notice when we’ve stopped thinking—and started deferring.
Representations are necessary. Representations are not authorities. The finger matters. The moon still matters more.
