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 products. 195 test claims and scenarios. 192 passed.

Veridi (fact-checking), Pragma (policy analysis), and Praxis (individual action synthesis) each carry their own validation set: adversarial scenarios, contested topics where experts disagree, and disinformation patterns drawn from the wild. These are three separate sets, summarized together here, 195 claims and scenarios in total:

  • Veridi: 99 of 100 claims correct in its rolling calibration corpus (99.0%); 1 partial, 0 failed. The corpus is the 95-claim February 2026 baseline plus the GTS-D Wave 1 extension added 2026-05-04; the validation report covers the full 97-claim baseline audit.
  • Pragma: 55 of 55 validation claims pass (100%), measured 2026-05-26 against v1.6 methodology (focused regression: both prior 2026-03-21 PARTIALs resolve to PASS); 0 failed.
  • Praxis: 38 of 40 validation scenarios pass (95%), measured 2026-05-26 against v1.4 methodology (focused regression: 4 of 6 prior PARTIALs resolve); 2 PARTIAL (PRXG-015 and PRXG-018, documented in known limitations); 0 failed.

Combined: 192 of 195. Each PARTIAL is a documented case with root-cause analysis, not a methodology failure; the changelog has the full breakdown and the focused-regression details.

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 13 vectors; Pragma names 14; 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.
