“Don’t bring your authentic self to work. I don’t want your authentic self to work. I want your professional self. I want your respectful self,” she told the Diary of a CEO podcast in an episode published in September 2025. “I want your empathetic self. I want your competent self. You can bring your authentic self to a Thanksgiving meal with your family if you’d like to.” 

Poumpouras, a Queens, N.Y., native, was a U.S. Secret Service special agent, polygraph examiner, and interrogator who served from 2000 to 2012, protecting U.S. presidents Bill Clinton, George W. Bush, Barack Obama, and George H.W. Bush. She’s now a law enforcement and national security analyst, the bestselling author of Becoming Bulletproof, and an adjunct professor at the City University of New York. 

“Could you imagine if I brought my authentic New York self to every interrogation I did?” she asked, recounting an interrogation from years ago in which she had to interview a 16-year-old boy who had allegedly assaulted a 3-year-old little girl.  

“What would my authentic self say? ‘What are you thinking? How could you? It’s a 3-year-old.’ No, I brought my professional self,” she said. 

What mattered more in that moment was getting a confession, she said, so she could find out what happened so the little girl wouldn’t be victimized again. “‘Okay, tell me what happened. Tell me more,’” she recalled saying. “Non-judgment. Poker face. You know why? Because what I think, my authentic self, is irrelevant.”

Poumpouras also argues bringing your authentic self to work puts the spotlight on one individual instead of prioritizing teamwork.

“Don’t come in and be phony. Nobody wants a phony. But [the] authentic self has become me, me, me, me, me. Everybody, check me out,” she said. “I was irrelevant. When you show up to work, wherever you work, [ask] what are you bringing to bring value to the whole team, because your authentic self could be, ‘I’m bringing my problems, I’m bringing my opinions. I’m bringing my judgments.’” 

“Honestly, nobody cares,” she added. 

What experts say about authenticity at work

In a Science of Personality podcast episode published in 2025, Ryne Sherman, chief science officer at Hogan Assessment Systems, also said authenticity at the workplace has its drawbacks.

“Bringing your authentic self to work could get you into trouble,” he said. It can cause professionalism problems, interpersonal conflict, and hinder career development, he added, giving the example of responding angrily by screaming, stomping, or sending a harshly worded email. While that behavior might feel authentic at the moment, it’s clearly unprofessional.

“When we resist doing those things, we are being inauthentic,” Sherman said. “We’re not responding in a way that is consistent with our true feelings.” But that’s a good thing, he added.

Other studies, however, show authenticity in the workplace can have its merits. Research by Cynthia S. Wang and other co-researchers at Northwestern University’s Kellogg School of Management, published in March, said authenticity at work can improve well-being, colleague relationships, and organizational commitment.

Wang found, though, that this can be particularly difficult for marginalized and minority groups at work. 

“What we’re talking about is actual authenticity—the ability to express yourself—which is slightly different from the idea of inclusion,” Wang said. “You can include somebody in a meeting, for example, but they still may not feel comfortable with being authentic and speaking up.”

Still, Poumpouras argues authenticity in the workplace inhibits high performance.

“You get sloppiness. Everybody’s doing their own thing,” she said. “That’s not a team.

“If you’re team-oriented, you leave your authentic self here, and you bring your genuine self, who genuinely cares about the mission, who genuinely cares to do a good job, who genuinely knows that it’s not about you, it’s about the collective team,” she added.
