Veridi, Pragma, Praxis

A suite of three open products

We are a Canadian cooperative-in-formation building three open products that share a discipline: explicit procedures, evidence classified by source quality, gaming detection, and transparent, auditable assessments. Each product addresses a distinct question:

• Veridi — Is this claim true?
• Pragma — What does the evidence suggest about this policy?
• Praxis — What can a specific person actually do about a goal?

Three methodologies. 192 carefully constructed claims. 189 passed.

Veridi (fact-checking), Pragma (policy analysis), and Praxis (individual action synthesis) each carry their own validation suite of adversarial scenarios, contested topics where experts disagree, and disinformation patterns drawn from the wild. Per-methodology results from the v1.2 combined run:

• Veridi v2.6 — 96 of 97 claims pass (98.97%); 1 partial, 0 failed
• Pragma v1.2 — 54 of 55 claims pass (98.2%); 1 partial (a robust-regardless arithmetic-path note), 0 failed
• Praxis v1.2 — 39 of 40 scenarios pass (97.5%); 1 documentation-level reconciliation, 0 failed

Combined: 189 of 192 (98.4%). Each partial is a documented case, not a methodology failure; see the combined v1.2 validation report for the full breakdown.

We will continue testing and evaluating against real-world input, recognizing that a test suite cannot fully capture reality.

Where would you like to start?

I want to check a claim - Plain-language guide to what Veridi does and how to use it.

I’m a journalist or fact-checker - Source hierarchy, verdict taxonomy, and how Veridi fits into professional workflows.

I’m interested in policy analysis - Evidence-based policy evaluation with transferability assessment, gaming countermeasures, and calibrated confidence.

I want to know what I can do - Find the highest-leverage actions for your specific situation, skills, and constraints.

Show me the data - Validation methodology, adversarial testing results, confidence calibration framework, and gaming countermeasure documentation.

I represent an organization - Mission, governance, impact potential, and partnership opportunities.

What makes the suite different

Sources are ranked, not trusted. A four-tier hierarchy classifies every piece of evidence across all three products. Multiple low-quality sources cannot substitute for one high-quality source; structural confidence caps enforce this.

Gaming is expected. Each methodology includes explicit detection procedures for documented disinformation and motivated-reasoning techniques: Veridi names 12 vectors (twelfth added in v2.7 for substrate self-reference); Pragma names 14 (corrected from 11 in the v1.2 audit); Praxis adds 6 native vectors plus 8 inherited from Pragma. Each treats reasoning under contestation as an evolving adversarial problem, not a lookup task.

Institutions can degrade (or improve). An Institutional Reliability Index tracks when formerly authoritative sources have been compromised by political interference or defunding. A source that was Tier 1 last year may be Tier 3 today; the IRI is shared infrastructure across all three products.

Everything is auditable. Each product’s methodology is documented and available on request. Every assessment shows its evidence, source tiers, confidence reasoning, and any gaming flags detected. The calibration feedback loop (v1.3) closes the loop between user-reported outcomes and methodology calibration without ever auto-modifying methodology files.

Open methodologies

The complete methodology files for all three products — Veridi’s source hierarchy and decision trees, Pragma’s evidence quality framework and normative reasoning, Praxis’s leverage matching and pathway portfolio — are documented in full and available on request.

What the methodologies contain

The pipeline

The three products form a complete evidence-to-action chain: Veridi (is this true?) feeds into Pragma (what does evidence suggest about policy?) feeds into Praxis (what can a specific person do?). Each product works independently and is useful on its own; together they let a user move from claim verification to policy reasoning to individual action without leaving the suite.
