Scope and questions
The subject of this index is proposed by NXS-GRX (canonical data, provenance and risk); the Nexus Reports edition with the same code sets its own subject at commissioning, and any difference is recorded as a crosswalk.
- Which decisions rely on unvalidated twins?
- How is model risk governed?
- What happens when the twin and the system diverge?
Domain indices to the series index
The series index is the expert-weighted geometric mean of its domain indices, with the intervals and class rule of the methodology.
How the Digital twins and simulation index is built
-
ガバナンスの脆弱性Domain index · IDX · GOVWeighted aggregation, on 0 to 10, of governance quality, rule of law, policy and institutional quality and statistical capacity, each oriented by its own polarity so that higher values mean weaker governance.
-
技術集中リスクDomain index · IDX · TECIndex of technology dependence, critical-mineral dependence and, inverted, innovation capacity and biosecurity oversight, on a 0–10 scale, higher meaning riskier.

ステータス
The Global Risks Index の手法、構造、定義は準備段階の作業草案(2026 年)であり、レビューと意見募集のために配布されているもので、実施を目的としたものではありません。管理されたエビデンスの区切りから版が公表されるまで、値は一切表示されません。公表後の値には、区間、区分、出典、訂正の経路が付されます。シミュレーターは、公表された手法をあなたが選んだ数値で実行するものであり、NXS-GRX の値を表示することはありません。
NXS-GRX ではないもの
NXS-GRX は研究およびリスク分析の情報です。信用格付や ESG 格付ではなく、格付尺度を用いず、金融商品のベンチマークでも、公的統計でも、緊急警報や公式分類でも、助言でもありません。自然人の評価に用いてはなりません。リスククラスは公開された尺度上の区分であり、国や人の順位付けではありません。
機関と情報源
The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.
すべての値には情報源の帰属表示が付され、情報源はそれぞれ独自のライセンスを保持します。外部の名称は相互運用性のためにのみ引用しています。Nexus が執筆したテキストは、公開時に CC BY 4.0 とする予定です。
Avis en français
La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
