Overview
GPS is built on public, traceable inputs
GPS uses a small set of source families repeatedly: prediction markets, institutional material, news coverage, and selected structured datasets. The mix changes by article type, but the source logic stays consistent.
No single source is enough. Markets are fast but incomplete. Official sources are authoritative but narrow. News adds detail and timing. Structured datasets help with scale and pattern detection.
The source base is not static. GPS is always testing new inputs, reviewing source quality, and expanding coverage where better public material becomes available. Source selection is a dynamic process shaped by topic, region, and the practical usefulness of the input.
Source Families
The main source categories used by GPS
Prediction markets
Market data shows how expectations are being priced in public. It is useful for timing, repricing, and shifts in conviction.
Institutional sources
Institutional material provides formal policy action, official statements, and primary documentation.
News coverage
Reported journalism adds narrative context, event detail, and near-term developments that may explain why attention is moving.
Structured and open datasets
Structured datasets help with pattern detection, event tracking, and broad comparison across regions and time.
How Sources Are Used
Each source type solves a different problem
GPS does not use multiple source types to create complexity. It uses them because each one contributes something different to interpretation.
Markets
Markets show what participants are pricing and when that pricing changes. They are useful signals, not standalone proof.
Institutions
Institutional sources define official action, legal position, and public policy constraint.
News
News coverage helps explain the event layer between formal developments and public reaction.
Transparency Standards
The source standard is clarity, not opacity
GPS prefers source material that readers can understand, inspect, and compare. Source transparency is part of the product, not a side note.
That standard also requires change over time. As new source sets become useful, older ones become less relevant, or coverage gaps appear, GPS updates the source mix rather than treating the input layer as fixed.
Public and attributable
GPS prefers sources that readers can trace and evaluate themselves.
Weighted, not flattened
Institutional, news, and market sources are not treated as interchangeable.
Useful over exhaustive
The goal is not to collect every source. The goal is to combine the right source types well.
Opaque claims avoided
GPS avoids building analysis on claims the audience cannot inspect or test.
