Measuring how AI engines render the principals who shape industries.
The 5W Reputation Index is a directional baseline measuring how major AI systems currently render prominent principals across sports, finance, media, and private capital. Nine sequential studies. More than 220 named individuals. Five systems, five dimensions: Accuracy, Sentiment, Completeness, Consistency, and Control.
Scores are directional estimates derived from modeled outputs and supplementary web-search verification — not logged query runs. The Index reflects machine-rendered reputation only. It does not evaluate any principal's actual conduct, character, or business practices.
Across the five dimensions, Control is the most manipulable. High-Control portraits emerge from direct publishing, annual letters, sustained interviews, foundations, and institutional continuity. Low-Control portraits emerge when external commentary writes the story.
The Index treats AI systems as reputational memory infrastructure, not search tools. Five proprietary terms recur across the series.
The dominant historical event disproportionately shaping a principal's current retrieval behavior.
The depth of primary-source material a machine system has to draw from. Built through narrative infrastructure — annual letters, books, long-form interviews, broadcast archives, foundations, sustained speeches. The moat behind sustained high rendering.
The half-life of a negative anchor event inside machine memory. Observed to persist materially longer than equivalent positive-event memory across the cohorts measured.
The portrait carried into a new role from a prior identity. The mechanism that lifts Belichick's UNC portrait and depresses Yaccarino's X portrait.
When a portfolio asset reshapes the principal's overall portrait. Manchester United dragging the Glazers. Arsenal and the Nuggets producing asymmetric Kroenke portraits. Liverpool stabilizing Henry. Commanders-era coverage persisting against Daniel Snyder long after the franchise sale.
Each study runs the same 14-section spine and the same 5-engine, 5-dimension methodology. Cohorts and case studies vary; the architecture does not.
1. Anchor events outweigh aggregate record. Every bottom-cohort principal across the 9 studies is shaped by a single defining anchor event. Sectors differ; the structural pattern is constant. Negative events persist materially longer than positive-event memory.
2. Narrative density beats capital scale. Buffett (86) vs. Walton (54). Rubenstein (84) vs. Glazer (38). Henry (78) vs. Tepper (49). The founder-philosopher pattern explains rank across every cohort measured. The principals at the top of every cohort built narrative infrastructure on purpose.
3. Cross-portfolio contamination runs bidirectionally. Manchester United damages Glazer's NFL portrait. Liverpool stabilizes Henry's MLB portrait. Lakers lift Walter. Patriots lift Belichick. Sector-by-sector reputation analysis underestimates the effect.
4. Control is the manipulable dimension. Cohort-average Control scores predict cohort-average composites within five points. High-Control portraits come from direct publishing, annual letters, interviews, foundations, and institutional continuity. The single most actionable finding for any principal in any sector.
5. These systems are reputational memory infrastructure. The 220+ portraits measured are the result of sustained machine memory — what synthesized identity becomes when an archive compounds across decades. Not search. Not retrieval. Memory.
