The Polygraph Files: Myths, Mishaps, and Must-Knows

Myth vs. Reality: What You Need to Know About Polygraphs


Myth 1: Polygraphs Are 100% Accurate and Always Determine Truth

Reality: Polygraphs are not “lie detectors.” They measure physiological responses such as heart rate, blood pressure, and sweat gland activity—signals that may indicate stress or anxiety. Trained examiners interpret these results, but several factors can influence the outcome:

  • False positives and false negatives happen.
  • Anxiety, medical conditions, or medications can affect readings.
  • Polygraphs are investigative tools, not final proof of truthfulness.
  • In the clearance process, a failed or inconclusive test often just means further review or a retest.


Myth 2: Failing a Polygraph Automatically Disqualifies You from Clearance

Reality: A polygraph is only one piece of the broader adjudication puzzle. Even if you “fail” a test, you may still move forward in the process. The full review includes:

  • Background checks
  • Interviews
  • SF-86 form review
  • Corroborating evidence from multiple sources

Many applicants are given another chance to take the polygraph or explain their answers before any decision is made.


Myth 3: You Can Beat the Polygraph with Tricks or Techniques

Reality: The internet is full of “tips” for beating the polygraph. Examiners are well aware of these tactics, and attempting them can:

  • Raise red flags and trigger suspicion
  • Lead to invalidated results
  • Damage your credibility more than a poor showing on the test itself


Trying to game the polygraph can backfire badly—often worse than just answering honestly.


Polygraphs can be stressful, but they’re not the final word in your clearance journey. The most important thing you can bring into the exam is honesty—both with the examiner and yourself. Understanding how polygraphs work, and knowing that a single test doesn’t determine your fate, can go a long way toward reducing the anxiety that comes with this infamous step in the process.

If you’re heading into a polygraph soon, take a deep breath, skip the internet “hacks,” and focus on telling the truth. The rest is just part of the process.

  • Mental Health, Security Clearances, and Why Getting Help Isn't a Career Killer

    10:22|
    Let's clear something up right away: having a mental health condition doesn't automatically put your security clearance on life support. Despite what your buddy's cousin's former coworker swears happened to "a guy he knew," the government isn't out here revoking clearances simply because someone sought therapy, took medication, or admitted they weren't feeling their best. One of the biggest myths in the cleared community is that getting mental health treatment is somehow worse than ignoring a problem and hoping it magically disappears. Spoiler alert: it isn't. Federal adjudicators care far more about judgment, reliability, and trustworthiness than they do about whether you've had a conversation with a therapist. Seeking treatment is often viewed as a sign of good judgment, not a red flag. John Berry and Lindy Kyzer frequently collaborate to demystify complex security clearance and federal employment laws. Kyzer is the Director of Content at ClearanceJobs, while Berry is a founding partner at the security clearance law firm Berry & Berry, PLLC. They talk this week about mental health issues, degenerative brain diseases like Alzheimer's, and other cognitive health matters.

  • What the Public Doesn’t Understand About the FBI, INTERPOL & National Security

    44:10|
    The public often views organizations like the State Department, FBI, DHS, and INTERPOL through the lens of movies and headlines. In reality, their work is far less about dramatic operations and far more about building relationships, sharing information, and preventing crises before they happen. At their core, these organizations are people-focused, relying on collaboration and trust to protect national and global security. On this episode of the Security Clearance Careers Podcast, we sit down with Dexter Ingram to discuss his remarkable journey, from serving in the U.S. Navy to leadership roles within the FBI and INTERPOL, helping shape public understanding of intelligence and espionage at the International Spy Museum, and inspiring the next generation through his nonprofit work and podcast, Dexter Ingram: Declassified.
