For over thirty years, the psychological establishment maintained a “conspiracy of silence” around the work of Hans J. Eysenck. That silence was finally shattered in October 2025 when King’s College London (KCL) issued a definitive, “high and far-reaching” warning, labeling Eysenck’s tobacco-funded research as officially unsafe.

As these posts make clear,  Eysenck’s frauds were not a sudden discovery. The “smoking gun” was first identified in 1992 by psychiatrist Anthony Pelosi—only to be ignored by the body meant to protect the public, the British Psychological Society.  Here is a brief summary of the checkered history of the Eysenck/King’s College London tobacco research saga.

The Prophet Ignored: Pelosi vs. The BPS

The story of the Eysenck scandal is a case study in institutional complicity to profit from secret tobacco company funding. In 1992, Anthony Pelosi and Louis Appleby published a critique in the BMJ calling Eysenck’s cancer-prediction data “scientifically impossible.” In 1995, Pelosi took his evidence to the British Psychological Society (BPS), filing a formal misconduct complaint. He provided proof of the “too good to be true” survival rates and raised the alarm about data integrity. However, the BPS refused to launch a formal investigation. The Society dismissed the complaint as “inappropriate” for their committee, effectively choosing to protect the reputation of a “giant of psychology” over the safety of the scientific record. This neglect allowed Eysenck’s industry-backed theories to remain in circulation for three more decades.

The Psychology Society had already been embarrassed by the Burt Affair, another scandal involving fraud by a senior figure, and it feared a second major catastrophe for the reputation of the discipline.

The Chronology of Exposure: 1992–2025

Year	Event	Documentation / Significance
1992	The Initial Whistleblow	Anthony Pelosi and Louis Appleby publish a devastating critique in the BMJ, questioning the “miraculous” survival rates in Eysenck’s data.
1995	The Rejected Complaint	Pelosi files a formal complaint with the British Psychological Society (BPS) alleging scientific misconduct. The BPS declines to investigate, calling it “inappropriate.”
1998	Tobacco Secrets Leak	The Master Settlement Agreement forces tobacco firms to release internal documents. Forensic researchers begin finding Eysenck’s name in secret payment ledgers.
2010	The Hans J Eysenck  Biography	Rod Buchanan publishes Playing with Fire, the first comprehensive look at Eysenck’s career that identifies systemic patterns of undisclosed industry support.
2019	The Tipping Point	After a last-minute rejection by Individual Differences and Personality, a journal founded by Eysenck, the Editor of the Journal of Health Psychology, David F Marks, accepts Anthony Pelosi’s critique of Hans Eysenck’s smoking research.  Marks publishes an Open Letter to KCL and the BPS about the issue, which ultimately forces King’s College London to finally launch a formal inquiry. Once again, the BPS failed to respond.
2019	KCL Initial Verdict	KCL rules 26 papers “unsafe.” This is the first official institutional admission that Pelosi was right in 1992.
2020–2024	The “88 List” Audit	David Marks and Rod Buchanan forensically prove the rot is much wider, identifying 88 specific publications using the same compromised data.
Oct 2025	KCL Final Verdict	KCL issues the “High and Far-Reaching” update, extending the “unsafe” label to all 88+ works, including sole-authored books.

The Paper Trail of Deceit

While the BPS chose to look away, the “smoking gun” was the funding hidden in the Tobacco Industry Archives. Internal documents (made public in 1998) reveal why Eysenck was so determined to prove that personality, not smoking, caused cancer:

• Bates No. 1361007: A secret ledger showing £800,000 in payments (approx. £2.5 million today) from tobacco firms to Eysenck.

• Bates No. CTRSP/FILES016121: A memo confirming Eysenck was a “Special Project” designed to “influence public beliefs” and provide “adversary value” in courtrooms to protect cigarette sales.

• It has been estimated that King’s Collge London received £2M funding (appox. £8M today) to support Hans Eysenck’s tobacco research.

The 2025 Verdict: “High and Far-Reaching”

In October 2025, KCL finally validated what Pelosi, and later forensic auditors David Marks and Rod Buchanan, had long argued: the rot was systemic. The university’s “High and Far-Reaching” update admitted that the failure tainted 88 different publications, including Eysenck’s major monographs:

• Smoking, Personality and Stress (1991)

• The Causes and Cures of Criminality (1989)

• Creative Novation Behavior Therapy (1991)

The Shadow Beyond Tobacco

The “High and Far-Reaching” designation warns us that where there is one secret funder, there are often others:

• Race and IQ: Eysenck’s work in this field, including The IQ Argument (1971), was bolstered by the Pioneer Fund. Eysenck kept this funding secret to maintain a facade of objectivity.

• Parapsychology: His collaborations with Carl Sargent, such as Explaining the Unexplained (1982), are equally compromised. Sargent left Cambridge under a cloud of fraud allegations, yet Eysenck continued to promote their joint data.

Conclusion: A Landmark for Integrity

The “High and Far-Reaching Smoking Gun” serves as a landmark warning. It took thirty years for institutional courage to catch up to Anthony Pelosi’s 1992 whistleblow and the BPS’s 1995 failure. The verdict is finally in: Hans Eysenck’s industry-funded “miracles” were nothing more than a dangerous, manufactured mirage.
