Apply Adversarial Verification

When information comes from a party with motivation to mislead, verify using designed tests, inconsistency detection, and independent corroboration — because in adversarial conditions, accepting stated information at face value is not due diligence, it is assumption.

Why This Is Best Practice

Why best: The 察智部 (Investigative Wisdom) of 智囊 contains dozens of historical anecdotes organized around a common pattern: an official, general, or judge receives information and must determine whether it is genuine or falsified. The recurring methodology across these cases: (1) design a test whose outcome depends on the truth — if the claim is true, X will happen; if false, Y; (2) look for inconsistencies between what was stated and what the physical evidence shows; (3) obtain corroboration from sources who have not been able to coordinate their story. This methodology is explicit in the text: "察" (察智) means investigative perception — seeing through the surface to the actual state.

CIA "Psychology of Intelligence Analysis" (Richards Heuer, 1999): Heuer's foundational work on intelligence analysis methodology establishes that the human mind naturally seeks confirming evidence and is systematically poor at detecting deception. His proposed counter: Analysis of Competing Hypotheses (ACH) — for each competing explanation, identify what evidence each hypothesis PREDICTS and test against observed evidence. Hypotheses that make false predictions are eliminated. Standard methodology at CIA, DIA, and major intelligence services globally; taught in intelligence analysis programs at George Washington University, King's College London, and others.

M&A due diligence practice: Every significant acquisition involves adversarial verification because the seller has motivation to present the company favorably and conceal liabilities. Standard due diligence methodology: verify stated financials against third-party records (bank statements, tax filings); look for inconsistencies between management representations and operational data; interview customers and employees independently (without allowing management to filter access). The $30B+ due diligence industry exists precisely because self-reported information in adversarial contexts is unreliable. Required by fiduciary duty at every major investment bank and private equity firm.
