The Psychology of Mirroring: The Sales Skill You Didn’t Know You Were Using

Originally published October 2020. Updated January 2026.

There is something that you do already subconsciously that provides an edge in sales. This sounds counterintuitive—if everyone is already doing it, how does it provide an edge? And if it’s subconscious, can we even control it?

I’m talking about mirroring. The psychology of mirroring is complex, but the act of mirroring is simple and something that can be practiced. While mirroring is something we do without noticing (much of the time), some people do it better than others, and some do it more than others. And while we do it naturally, it’s still something we can pay attention to and improve. When done skillfully, mirroring can increase your persuasiveness, your attractiveness, and your bottom line.

WHY SHOULD WE CARE ABOUT THE PSYCHOLOGY OF MIRRORING?

Mirroring is when an individual (usually subconsciously) mimics the behavior of another person—their gestures, attitude, or speech pattern. It happens all the time in social interactions, even though neither the person doing the mirroring nor the one being mirrored even notices. The psychology of mirroring is a huge part of human social behavior. It is an innate trait among humans and other primates that allows us to understand how another person is feeling, and helps to establish trust and rapport between two individuals.

We don’t all mimic others equally well, however, which may explain why some people interact and connect with others more easily. We know that extroverts generally have higher-quality social interactions, which help them build rapport, but for a long time, we didn’t know why. Researchers measured eye contact, smiling, and openness between individuals and found that there was no significant difference between introverts and extroverts.

Scientists at Duke University studying the psychology of mirroring think they have solved the introvert/extrovert puzzle. They found that when individuals were asked to cooperate with a partner in a word game, extroverts exhibited significantly more mirroring behavior. Interestingly, without the prompt to cooperate, introverts and extroverts exhibited the same amount of mirroring behavior. So, when extroverts want to get along with another person (like when they are trying to impress a date or make a sale), they subconsciously do more mirroring, while introverts don’t. Should you only hire extroverts from now on? No. Should you encourage your sales team to intentionally mimic customers and prospective clients? Definitely. Studies have shown that, when mirroring is done well, waitresses get higher tips, sales reps achieve higher sales and better evaluations, men view women more favorably in speed dating, and students convince more peers to do their homework for them.

THE PSYCHOLOGY OF MIRRORING: NOT TOO MUCH AND NOT TOO LITTLE

Notice the caveat that I included—when done well. Don’t mirror someone so much that you’re not acting like yourself. Think of the psychology of mirroring not as acting like someone else, but as taking postural and vocal cues from another person. Maybe you’re naturally loud and boisterous, but you’re meeting with someone who is quiet and reserved. You shouldn’t suddenly become meek and inhibited, as this would be completely inauthentic, but you should tone down your enthusiasm.

Mirroring others well can help put them at ease. I had a graduate school advisor who was rather intimidating. Think Abraham Lincoln with more hollowed-out cheeks. When I met with him, I was uncomfortable. My normal chatty, smiley self became even more chatty and smiley due to nerves. He never cracked a smile. He never altered his stiff posture. Just one look of mild amusement would have made such a difference. He never mirrored his students, but I often watched him mirror the energy of his colleagues. Another example of bullies harnessing the psychology of mirroring for their own gain?

THE PSYCHOLOGY OF MIRRORING ON THE PHONE AND ON ZOOM

Even when you’re not together, and even when you can’t see the other person, mirroring is still an effective tool. Pay close attention to vocal tone and pace when you’re on the phone or can’t see someone’s body language cues very well.

More specifically, pay attention to the quality of what’s being said (casual or formal, use of slang or industry jargon), how loud your counterpart is speaking, the length of time they speak, pacing of speech, and emotion. These are all characteristics that you can assess without seeing anyone.

THE PSYCHOLOGY OF MIRRORING OVER EMAIL

You don’t even have to see or hear someone to take advantage of the psychology of mirroring. Just as mirroring someone’s speech improves their perception of you, mirroring someone’s writing does the same thing. Andrew Brodsky, management professor at the University of Texas’ McCombs School of Business and author of Ping: The Secrets of Successful Virtual Communication, encourages people to mirror language cues in email. If they use emojis, you use emojis; if they are more formal, you should also be formal.

In Maestro’s sales training, we teach the same thing. There are certain best practices for cold emails, but once you’re engaged with someone, you can alter some of those practices to match your prospect. There are now tools that can help you harness the psychology of mirroring before you reach out. Crystal Knows is an AI-powered platform that looks at public data to identify a person’s DISC personality profile. There’s even a Chrome extension that you can try out for free. The assessments are surprisingly accurate. Now you can even mirror a prospect’s communication style in cold outreach.

THE PSYCHOLOGY OF MIRRORING AND AI

Not only can AI help you mirror others, but AI mirrors you. Why do you think we’re all such big fans of ChatGPT and Gemini? Yes, they can help us do an innumerable number of things, but it’s more than that. As we interact with these large language models, they take on our personas. ChatGPT will mirror your intelligence, your views, and your language. I mean, it knows 45 terabytes worth of data, but somehow never makes you feel stupid. These large language models have mastered the psychology of mirroring.

WHAT IF YOU DON’T MIRROR WELL? PRACTICE!

The good news is that, even if you’re an introvert, you can improve your mirroring skills. More than anything, you just need to remember to do it. In fact, when MBA students were told to mimic their counterpart during a sales exercise, even though it was just before a negotiation and they had no time to practice, their sales outcomes improved by 400 percent!

Rather than waiting until the last minute, though, it’s best to get in some practice before an important client or prospect meeting. The great thing about mirroring is that you can do it with anyone. Practice the psychology of mirroring at home with your family or with coworkers. The main hiccup to watch out for is overdoing it. Don’t copy absolutely everything your counterpart does, and never mimic one of their nervous habits. Unless, of course, you’re a bully.
