Expert Witness Simulation

The opposing expert’s
report, before they write it.

Supreme Mind simulates the expert the other side will retain: their likely opinion, the weaknesses a cross would target, the Rule 702 attack surface, and what it means for the settlement range. Every supporting quote verified against the public record.

Individual simulations are $50 each. Example cases are free on a firm email address, and firms run on credit plans with volume pricing. See pricing.

01
Likely opinion
Will testify that price-impact rebuttal is unsupported; cite Cammer/Krogman, lean on multi-day window analysis.
02
Cross-examination weaknesses
Post-hoc window selection (Anadarko parallel). Confounding-events gap. Leakage doctrine under Bricklayers.
03
Methodology challenges
FRE 702 / Daubert: error-rate disclosure incomplete. Peer-review absent on extended-window method.
04
Settlement-range implications
Methodology challenge likelihood: high. Verdict-band shift if excluded: −$48M to −$62M (directional).
Why Now

The seventh revolution in law.

Six times, knowledge a small class controlled became legible to everyone who needed it, and six times lawyers ended up more capable rather than less necessary. The seventh arrived in 2025, when frontier models crossed PhD-level performance on the reasoning expert work runs on and the federal record became machine-readable. It is the first where what gets automated is not the finding. It is the thinking.

Firms stop rationing the read. They run it on every matter and every expert, before they commit.

What Changes

The same thirty days, spent on argument instead of waiting.

Rule 26(a)(2)(D) gives you 30 days to rebut a served expert report. Nothing moves that deadline: not the discovery stay, not the court’s calendar, not us. What changes is how much of the window is left once you understand what you are answering.

The first read arrives on day zero, in about 90 seconds. You still read the report yourself. What you no longer wait weeks for is an expert telling you where it is weak.

The strategic artifact.
The settlement engine.

Layer one: the per-archetype simulation, returning a structured artifact your trial team can act on. Layer two: a thousand agent-to-agent simulations across the case fact pattern, surfacing the top and bottom one percent of strategic outcomes.

Layer 1: Available now

The Archetype Simulation

One archetype. One fact pattern. About 60 to 90 seconds of frontier-model reasoning. The output is the strategic artifact a senior expert produces in the first weeks of an engagement, delivered in seconds for $50 per simulation.

  • Likely opinion: what the archetype concludes given the fact pattern, in the archetype's voice and methodological vocabulary
  • Cross-examination weaknesses: ranked vulnerabilities a competent opposing attorney would target, citations to the case file
  • Methodology challenges: Daubert, Frye and FRE 702 attack surface, keyed to challenges documented in the public record
  • Settlement-range implications: directional signal on how the testimony shifts the settlement distribution, with explicit uncertainty
  • Never filed, never testifies: internal strategy for your team, not a testifying opinion, which sidesteps the admissibility question entirely
  • Public-record training data: bounded, citable, defensible
  • Methodology fidelity to the expert class, built from the public corpus. A class, never a named individual
Layer 2: Research preview

The Agent-to-Agent Settlement Engine

A thousand simulations per matter. Your archetype roster argues against opposing counsel's archetype roster across the full case fact pattern. The top one percent of outcomes surfaces the arguments and strategies that maximize settlement leverage. The bottom one percent surfaces the destructive paths to avoid before they show up at trial.

Layer one makes one expert cheap. Layer one thousand makes the whole argument searchable. Where this goes is a world where the other side is running the same thing, and the advantage moves to whoever has explored more of the space before the first deposition is taken.

  • 1,000 agent-to-agent simulations per matter, on the same archetype infrastructure
  • Top 1%: the argument paths that maximize settlement leverage for your firm
  • Bottom 1%: the destructive strategies to identify and avoid
  • Sensitivity analysis: which assumption or witness choice shifts the verdict band
  • Research preview: design partners only
The Live Cross · Worked Example

Put him on the stand before the deposition.

The four artifacts are the static deliverable. This is the other half: you play counsel, the engine voices the expert defending its own report from the facts of the matter. Ask the questions in order, then switch the posture and run it again. A cooperative witness lets you walk a straight line; a hostile one makes you build the same line out of closed questions.
