METHODOLOGY
The Complicity Index measures documented corporate complicity in Israel's occupation on a scale from 0 to 1,000. Higher scores indicate more serious documented involvement across military, digital, economic and political domains. It is a consumer-awareness tool, not a legal liability framework. It asks one question: is a company's relationship with Israel's occupation material and significant enough that a consumer or investor would reasonably want to know about it? Every claim that feeds a score is cited to public evidence - 38,248 sources across 440 companies.
Every company is investigated across four independent domains. The audits contain evidence only - no scores, no conclusions - and every factual claim carries an end-noted citation. Where we searched and found nothing, the audit says "No public evidence identified": gaps are shown, not padded.
Each domain receives three component scores from the audit evidence: Impact (what the company does), Magnitude (how big it is - to the company or to Israel, whichever is higher), and Proximity (how direct the relationship is). They combine as:
V = I × min(M / 7, 1) × min(P / 7, 1)
The four domain scores then produce the composite Complicity Index score. The dominant domain carries the score; the remaining three enter as their average, at a 0.2 weight:
BRS = ((VMAX + 0.2 × AvgOTHERS) ÷ 12) × 1000
Formula revised August 2026. The previous formula summed the non-dominant domains against a larger divisor, which had the effect of discounting a company for being clean in three domains while deeply complicit in one. The revision weights the single worst domain more heavily — a company's score is now primarily its most serious documented conduct, adjusted for the breadth of the rest. A fully complicit company still scores 1000, and a company with equal complicity across all four domains scores identically under both formulas; concentrated profiles score higher than before, and no company scores lower.
Scores are computed deterministically from vetted component values - the arithmetic is checked by validation scripts, not trusted to judgment. Every listed company has passed the evidence gates, independent examiner review required by its method, and final human vetting.
Method labels describe how the evidence was converted into component values. The public formula and tier thresholds above are shared across the current index. Each company page shows its method beside the review date.
| Tier | Range | Reading | Companies listed |
|---|---|---|---|
| A Extreme | 800–1000 | Core, systemic involvement in the machinery of occupation | 29 |
| B Severe | 600–799 | Severe, sustained material support in at least one domain | 98 |
| C High | 400–599 | Significant documented involvement | 102 |
| D Moderate | 200–399 | Moderate or indirect involvement | 127 |
| E Limited | 0–199 | Limited documented nexus | 84 |
Every dossier shows its last-updated date. The index is regenerated from the underlying research corpus, so corrections propagate to every affected page. If you believe a cited fact is wrong or out of date, contact us with the claim and the source - corrections are reviewed against the same evidence standards above.
