Despite the Trump administration’s growing emphasis on polygraphs as a tool to weed out protestors in the federal government, polygraphs are widely considered to be unreliable measures of lies.
Polygraphs, more commonly known as lie detector tests, measure physical reactions like changes in breathing, sweating on the hands, and blood pressure. Major Cabinet officials have used , the tactic , in recent weeks to catch leakers from national sections.

But, experts caution that the test is not everything it is portrayed to be.
According to the American Psychological Association, which has advised against using lie detector tests in examinations, the majority of psychology concur that there is little evidence that polygraphs is properly find lies. According to the APA, polygraphs are a better predictor of stress than lying.
Researchers wrote that” the correctness of polygraph testing has long been controversial. There is no proof that any style of physiological reactions is distinct to fraud, which is an underlying problem is philosophical. An honest man may not be irritable when responding honestly, and a unscrupulous man does not.
Polygraphs are normally prohibited from being used as evidence in court. The Supreme Court decided that” there is simply no compromise that polygraph data is credible” in the 1998 event United States v. Scheffer, ruling that “polygraph evidence is illegal in a court-martial moving.”
There is no one particular biological sign of fraud, according to Leonard Saxe, a neurologist at Brandeis University who has conducted studies into polygraphs for years. And there is no proof whatsoever that telling the truth or lying about something is related to the things the test measures, such as heart rate, blood pressure, sweating, and breathe.
The estimate is still widely used, including by the major federal departments, government companies, and law protection, because “it doesn’t matter whether the check really works, just that it’s perceived to be effective.”
Polygraphs are used as a ball, according to advocates, part of what Saxe characterized as the” drama” of questioning in feedback to the outlet.
They might confess if the auditor effectively deceives the issue into believing their lies can be discovered, he said.
The American Polygraph Association defends its claim that” when conducted in accordance with APA Standards of Practice,” clinical evidence supports the validity of polygraphs. The APA conducted research in 2011 that supported its opinion, finding that the combination of all approved psychophysical detection methods, excluding outlier results, resulted in an 87 % choice accuracy.
Members of President Donald Trump’s cabinet have discussed and used polygraph testing to identify leakers in their departments, including FBI Director Kash Patel, Homeland Security Secretary Kristi Noem, Defense Secretary Pete Hegseth, and Attorney General Pam Bondi.
Tricia McLaughlin, a spokeswoman for the DHS, stated to the Washington Examiner,” The Department of Homeland Security is a national security agency. ” We can, should, and will polygraph personnel,” he says. Under Secretary Noem’s guidance, DHS is unapologetic about its efforts to catch leakers who threaten national security. We will find leakers and prosecute them to the fullest extent of the law because we are agnostic about your standing, tenure, political appointment, or status as a career civil servant.

According to Converus, the device’s creator, some government entities and law enforcement organizations are using a new lie-detection tool called EyeDetect. According to the Intercept, Converus is working with the CIA and DHS to adopt EyeDetect.
Whether or not they use EyeDetect was not made public by the DHS and FBI. The Washington Examiner contacted the CIA and the Defense Department for more information, but they did not receive a response.
