Hiring the wrong candidate isn’t just costly—it’s a direct hit to your team’s morale and productivity. What if you could vet candidates like a CIA officer, detecting deception with razor-sharp precision? In Spy the Lie, former CIA agents Philip Houston, Michael Floyd, and Susan Carnicero share a groundbreaking methodology that transforms how you approach interviews and hiring decisions. Here’s how their expertise can help you uncover the truth—and avoid hiring disasters.
1. Look for Convincing Instead of Conveying
This technique, developed by Philip Houston during his years at the CIA, focuses on how liars overcompensate. Instead of addressing questions directly, they try to convince you of their honesty or good character.
“If the truth had been on [their] side…everything [they] said would have focused on that,” Houston explains.
Example: You ask about teamwork, and the candidate says, “I’m a people person. Everyone loves working with me!” instead of providing specific examples.
👉 Focus on answers that directly address your question with concrete facts.
2. Pay Attention to Timing
Also attributed to Philip Houston, this method draws from his polygraph expertise. Observing a candidate’s behavior within five seconds of a critical question can reveal deceptive responses.
“The first deceptive behavior to occur within the first five seconds…can reasonably [indicate] the behavior is directly associated with the stimulus,” Houston notes.
Example: You ask, “Why did you leave your last job?” If they hesitate or fidget before answering, it could signal discomfort with the question.
👉 Pay close attention to those first few moments after your question.
3. Ask Questions That Assume the Truth
Michael Floyd often used presumptive questions during criminal investigations and personnel screenings to elicit confessions. These questions assume a truth, making it harder for candidates to lie without revealing more.
“Presumptive questions…are remarkably effective in eliciting truthful responses,” Floyd explains.
Example: Instead of asking, “Have you ever missed a project deadline?” ask, “What was your biggest challenge when you missed a deadline?”
👉 Use questions that nudge candidates to reveal specifics naturally.
4. Watch for Patterns, Not Single Behaviors
Susan Carnicero’s expertise in behavioral screening shaped this advice. She emphasizes identifying clusters of behaviors—such as verbal inconsistencies and restless body language—rather than reacting to one-off signs.
“A cluster is defined as any combination of two or more deceptive indicators,” Carnicero explains.
Example: A candidate crosses their arms, avoids eye contact, and changes the subject when asked about a gap in their resume. These behaviors together indicate discomfort.
👉 Look for patterns, not isolated behaviors.
5. Use a Catch-All Question to End
This strategy comes from Susan Carnicero’s background in high-level screenings. She found that a well-phrased catch-all question often reveals what candidates hope you won’t ask.
“What haven’t I asked you that you think I should know about…?” Carnicero suggests.
Example: Honest candidates might add helpful details. Deceptive ones may hesitate, deflect, or scramble.
👉 End interviews with this powerful question and observe their response.
6. Forget the Myths About Body Language
All three authors collectively debunk the common myths about body language—like assuming crossed arms or lack of eye contact means dishonesty. They advocate evidence-based analysis instead.
“There simply isn’t a sufficient body of anecdotal or empirical evidence to support [these myths],” Carnicero points out.
Example: A candidate might cross their arms because they’re nervous or cold, not because they’re lying.
👉 Avoid stereotypes; focus on behavior patterns and timing.
7. Be Aware of Your Biases
Philip Houston admits even professionals like him struggle with biases. He shares how his own family dynamics shaped his understanding of how bias impacts judgment.
“Bias…is a simple fact of life, and it’s not necessarily negative at all. But it has a huge impact on whether or not we believe someone,” Houston explains.
Example: A candidate who shares your alma mater might seem more trustworthy, but that doesn’t mean they’re being truthful.
👉 Be conscious of your biases and assess candidates objectively.
8. Keep Interviews Friendly
Michael Floyd’s nonconfrontational style, honed over thousands of interviews, shows that a calm and friendly approach encourages honesty.
“The idea is that when the individual walks out…he feels good about what he’s done, because he doesn’t see you as an adversary,” Floyd emphasizes.
Example: Instead of grilling a candidate about resume gaps, ask gently, “What kept you busy during this time?” They’re more likely to share openly.
👉 Treat interviews as conversations, not interrogations.
Final Thoughts
Using these expert insights, you can turn every interview into a masterclass in detecting truth. Whether it’s spotting patterns, asking smarter questions, or managing your own biases, these strategies will help you hire confidently.
