If you are a federal employee facing mandatory polygraph screening, use Tor Browser or a VPN and download a copy of our free book, The Lie Behind the Lie Detector, to protect yourself against this fraudulent pseudoscience. Re-post to help spread awareness.

Ironically, this commonly shared GIF shows the exact opposite of "no lies detected." The finger is pointing to reactions that polygraph operators hold to be indicative of deception. (Of course, it's all hocus-pocus.)

Alder also names the part my dissertation studied: the examiner’s discretion decides the result, and that’s where racial and confirmation bias get in. And the confessions the ritual pressures out of people tell you nothing about whether the machine works. wildetruth.substack.com/p/everybodys...

wildetruth.substack.comEverybody's Got Bias Problems Except Me and My ScienceWhat research questions should we prioritize? How did my dissertation get it so wrong? And could sharing the data now still do some good?

The National Academies laid this out in 2003: screen 10,000 employees who include 10 spies, set the test to catch 8, and about 1600 innocent people fail along the way.

Ten years ago I gave the response to Ken Alder’s polygraph keynote in Osaka. Now he's on Throughline making the point I built a career on: test thousands of people with an accurate test and false positives bury you while the real cases slip by. “The math is terrible.” www.npr.org/2026/10/20/n...

Nothing drives me more crazy when police act like it is suspicious when somebody refuses a polygraph. IT IS JUNK SCIENCE. Nobody should ever, ever agree to a polygraph even if they know they are 100% innocent. At this point, it shouldn't even be allowed as a tactic just like it isnt allowed in court

Today would have been polygraph critic Doug Williams's 81st birthday. In 2015, he was sent to prison on trumped-up charges. In 2021, he died less than a year after completing a 2-year sentence and 3 years of supervised release.

29 years ago today, on 29 September 1997, the FBI's top scientific expert on polygraphs likened polygraph screening to astrology or tea-leaf reading in testimony before Congress.

Less than four years after Dr. Richardson's damning testimony on polygraphs, in a knee-jerk reaction to Hanssen espionage case, the FBI greatly expanded its use of polygraphs to screen employees. Then FBI Director Louis Freeh ignored Dr. Richardson's advice: antipolygraph.org/documents/ri...

25 years ago today, on 21 September 2001, the Defense Intelligence Agency's top analyst for Cuban affairs was arrested on charges of spying for Cuba. She had beaten the polygraph. DoD's response? More polygraphs!

My latest on Hegseth weaponizing polygraphs. You can’t “pass” or “fail” a lie detector test — just like you can’t “pass” or “fail” a cognitive assessment. They measure physiology, not truth. And the truth is that Iran conflict depleted key munitions. #PolygraphTheater www.salon.com/2026/09/14/p...

One lesson not learned from 9/11 is that polygraphs don't work and are easily beaten, and that (as we have documented) Salafist militants are well aware of this. Yet in its countermeasures course, the federal polygraph school disregards this fact.
