I’ve interviewed hundreds of experts as an investigative reporter and host of the True Crime Reporter® podcast. Still, few speak with the unflinching clarity of Robin Dreeke—a former FBI Special Agent whose job was to predict human behavior and determine the trustworthiness of a person.
Dreeke headed the FBI’s elite Behavioral Analysis Program in counterespionage, where his team worked shoulder-to-shoulder with agents chasing traitors and recruiting Russian spies. He authored Sizing People Up, a book grounded in hard-earned experience. In our conversation, he made one thing chillingly clear:
“Trust is the bedrock of everything,” Dreeke told me. “When that’s betrayed, peril comes our way.”
Through the lens of espionage, Dreeke developed a framework to predict human behavior—one that applies just as well to your personal and business relationships, your online life, and the stranger walking too close behind you in a dark parking lot.
The Six Signs That Someone Can Be Trusted
At the heart of Dreeke’s behavioral model are six questions. They’re not about gut feelings alone but observable behaviors—what people do as well as what they say.
- Vesting – Does this person believe they benefit from your success?
- Longevity – Are they thinking long-term with you?
- Reliability – Do they follow through? Do their actions match their words?
- Actions – Are they consistently positive in behavior?
- Language – Do they speak with respect and consideration?
- Stability – Are they emotionally secure and socially aware?
According to Dreeke, these are not just good-to-know traits. They are predictive markers of whether someone will help or harm you.
He explained it this way:
“What I’m looking for is congruence—between someone’s words, actions, and deeds,” he said. “If their language is about us, not them—if they validate you, empower you, make you feel seen and not judged—and if their body language and pace align with that, then you’re likely in a safe place.”
But if their words don’t match their actions? If they suddenly shut down or change tempo when asked for clarity? Take note.
“That pause? That shift? That’s when you’re seeing someone who may be hiding something,” he warned.
Why the Hair on the Back of Your Neck Matters
In the field of behavioral analysis, instincts aren’t dismissed. They’re data.
When I asked Dreeke about that creepy feeling we all get—when something feels “off”—he didn’t chalk it up to superstition. Quite the opposite.
“We’re all baselining the world around us, constantly,” he explained. “When something spikes out of that baseline—someone’s pace, their energy, their purpose—it hits us as discomfort. That’s not irrational. That’s evolution.”
He told me about the Ariana Grande concert bombing in the UK. A security guard noticed someone who didn’t fit—his clothes, behavior, and presence were off. But the guard hesitated, afraid of overreacting. The result was tragic.
That hesitation is something Dreeke works to eliminate.
“You don’t have to guess at what’s wrong,” he said. “Just say, ‘Hey, something’s off. Maybe take a look at this.’ It’s better to be wrong and safe than right and sorry.”
Don’t Be an Easy Target
We often think of predators as hiding in the shadows. Dreeke sees them in plain sight—studying us.
“A predator wants the easy kill,” he told me. “They’re not going after someone who looks alert and aware. They’re looking for the distracted one—the person glued to their phone in a parking lot.”
He compared it to nature.
“A wolf doesn’t go after the strongest deer. It picks the one limping behind the pack.”
We talked about cases where people ignored their instincts. Women followed by strangers in parking lots. Parents who dismissed red flags around a coach or teacher. And worst of all, victims who knew their attackers.
Most Crimes Aren’t Random
Dreeke’s insights align with decades of data from the FBI and Justice Department. According to official reports, the majority of violent crimes are committed by someone the victim knows—family members, acquaintances, or people in their circle.
“It’s almost never random,” Dreeke said. “People escalate. Healthy people don’t just snap. There are arcs—patterns—of unhealthy behavior long before something violent happens.”
He referenced James Clear’s book Atomic Habits and how behavior doesn’t leap from zero to a hundred. It builds.
Animal cruelty. Sudden outbursts. Manipulation. Rage. These are warning signs, not quirks.
“The negative tells of trust,” Dreeke called them. “Lack of openness. Wordsmithing. Dodging questions. Using shame as a tool. Those are red flags—especially when someone’s pushing a tempo you’re uncomfortable with.”
Online Predators and Digital Deceit
In today’s digital world, Dreeke sees the same patterns—only magnified. He spoke about the rise of scams, particularly romance cons and fake pleas from “friends” asking for money.
“These people weaponize trust,” he said. “They hijack relationships—real or perceived—to make you act against your best interest.”
Dreeke’s own mother-in-law was targeted. Her email account was hacked. Her contacts received a plea for help that sounded like her—but wasn’t.
“It was a behavior spike,” Dreeke said. “That’s not something she’d ever do. That’s how I knew.”
In his words, the answer is simple, but not always easy:
“Trust—but verify.”
My New Watchword: Stop. Pause. Observe.
Dreeke left me with three words that now headline my Stories to Keep You Safe newsletter.
“Stop. Pause. Observe,” he said. “Not with suspicion. With awareness.”
When leaving your house. Walking into a store. Meeting someone new. Pause. Take in the environment. Get a feel for what normal looks like—so you’ll recognize when something isn’t.
