A closer look · Amicus Index

A claim should show its footing.

Amicus Index distinguishes a documented fact from a pattern, an interpretation, or an inference. Readers can see what kind of claim they are being asked to consider—not just how confidently it is written.

Read the evidence framework
Amicus Index’s four evidence tiers. Fact: documented, verified, sourced. Pattern: multiple facts forming a trend. Analysis: interpretation of patterns. Speculation: inference beyond available data.

The problem

Public claims can acquire authority without making clear whether they rest on a documented fact, a broader pattern, an interpretation, or an inference.

The contribution

The work connects information architecture, an explicit evidence model, and a publication experience that lets readers inspect a claim’s footing.

Decisions that shaped the work

  1. Make evidence classification part of the reading experience rather than burying it in editorial policy.

  2. Keep the documented record adjacent to the institutional promise through the Said vs Did structure.

What was implemented

  1. A public field guide, evidence framework, and source-tiered publication structure.

  2. A live Said vs Did evidence set with deliberately limited archive exposure.
