Donald Cressey and the Fraud Triangle: Why Smart People Commit Fraud
Before the Fraud Triangle became a staple of textbooks, Donald Cressey turned a hard question into a durable map: why do respected people steal when they have something to lose? The answer, he argued, begins not with greed alone, but with pressure, opportunity, and the private logic of rationalization.

Timeline
Publication of *Other People’s Money*
**1953** — Donald Cressey publishes *Other People’s Money: A Study in the Social Psychology of Embezzlement*, grounding his theory in interviews with incarcerated embezzlers. The book supplies the empirical basis for the later fraud triangle: pressure, opportunity, and rationalization.
Fraud triangle enters professional shorthand
**1973** — By the early 1970s, Cressey’s ideas are being compressed into the now-familiar three-part model used in fraud education and control design. The framework starts migrating from criminology into accounting and audit practice.
Death of Donald Cressey
**1987** — Cressey dies in 1987, leaving behind a theory that will outlive him and become a standard reference point in fraud prevention. His death marks the end of authorship, not the end of influence.
Fraud triangle updated in the academic literature
**2003** — Later scholars revisit Cressey’s model and refine its use for auditors and investigators, helping turn it into a standardized training tool. The theory’s persistence shows how deeply it has been absorbed into professional practice.
Audit training and compliance adoption
**2004-2006** — Professional associations and corporate training programs increasingly use the fraud triangle to teach risk recognition and internal control design. The model becomes a common shorthand for identifying fraud vulnerability.
Global financial crisis heightens scrutiny of fraud and controls
**2008-12** — The financial crisis intensifies public attention to weak controls, deceptive incentives, and institutional trust failures. Fraud scholars cite Cressey’s framework as a way to explain why pressure and opportunity can converge during systemic stress.
SEC charges Bernard Madoff
**2009-02-17** — The SEC files its complaint against Bernard Madoff, turning a massive investment fraud into a public enforcement case and forcing a broad conversation about why so many sophisticated people missed the warning signs. The scandal becomes an emblem of opportunity and rationalization at scale.
Madoff pleads guilty
**2009-03-12** — In federal court, Bernard Madoff admits that his investment advisory business was one large fraud. The case becomes a public example of how trust, status, and control failures can hide deception for years.
Cressey’s theory widely invoked in media and regulatory analysis
**2009-03** — As commentators and regulators search for explanatory language, the fraud triangle is repeatedly cited as a framework for understanding the scandal. The theory’s public visibility expands beyond academia into mainstream financial discourse.
Scholarly debate over the triangle’s limits intensifies
**2010** — Researchers argue that the fraud triangle, while useful, is incomplete without attention to capability, culture, and organizational context. This debate helps inspire later refinements such as the fraud diamond.
Fraud diamond concept gains traction
**2011** — The addition of capability to fraud analysis reflects an effort to improve on Cressey without discarding him. The triangle remains foundational even as scholars acknowledge its limits.
Fraud triangle still standard in training and audit practice
**2024** — Decades after Cressey’s death, the model remains a staple in fraud examination, internal audit, and compliance education. Its persistence underscores the continuing relevance of pressure, opportunity, and rationalization as a practical lens.
