Research

The research behind a sincere compliment.

What the research says about recognition at work, what turnover really costs, and what happens in the brain when someone says something true and kind. Every number has its source next to it, so you can look it up.

The short version

Most people go weeks without hearing they did something well. The ones who do hear it stay longer. And a sincere compliment lands better than the giver expects.

At work

Recognition is rare, and it matters.

29%

of U.S. workers strongly agree they received recognition or praise for good work in the last seven days.

Gallup, May 2026
2×

Employees who don’t feel recognized are twice as likely to say they will quit in the next year.

Gallup, “Employee Recognition: Low Cost, High Impact”
45%

less likely to have left two years later, for employees who received high-quality recognition (about 3,500 people tracked from 2022 to 2024).

Gallup and Workhuman, 2024
22%

of employees say they get the right amount of recognition. Only 11% have ever been asked how they like to be recognized.

Gallup and Workhuman, 2024
73%

of workers say their organization gives no best-practice recognition training.

Gallup and Workhuman, 2022 (7,636 U.S. workers)
57%

of U.S. workers who quit a job in 2021 said feeling disrespected at work was a reason.

Pew Research Center, 2022

Modelled by Gallup and Workhuman, 2023

If the median company doubled the share of people recognized each week

The model shows about 9% higher productivity, 22% fewer safety incidents and 22% less absenteeism. For a 10,000-person company, they put it at $91.9 million in productivity, $3.8 million from fewer absences and $2.8 million from fewer injuries. These are modelled figures, not measured results, and they can’t be added together.

“From Praise to Profits,” Gallup and Workhuman, 2023

Gallup’s meta-analysis, 2024

Highly engaged teams compared with the least engaged

Across 3.3 million employees, the most engaged teams showed 23% higher profitability, 78% less absenteeism and 63% fewer safety incidents than the least engaged. Recognition is one part of engagement, not the whole of it.

Gallup Q12 Meta-Analysis, 11th edition, 2024
31%

of U.S. employees are engaged at work, and 17% are actively disengaged.

Gallup, 2026
~$10T

Worldwide, only about 20% of employees are engaged. Gallup puts the lost productivity at about $10 trillion, or 9% of global GDP.

What turnover costs

Every person who leaves takes money with them.

Gallup estimates that replacing an employee costs one-half to two times their yearly salary, and that turnover costs U.S. businesses about a trillion dollars a year.

  • About 40% of payto replace a frontline worker
  • About 80% of payto replace a technical or professional worker
  • Up to 200% of payto replace a leader or manager

Gallup, “This Fixable Problem Costs U.S. Businesses $1 Trillion,” and “Employee Retention Depends on Getting Recognition Right,” 2024.

A worked example

Twenty people paid $40,000. Six leave in a year. At 40% each, that is $96,000 walking out the door.

The science of compliments

What happens when someone says something true and kind.

It lights up the brain

Praise lights up the same reward area as money.

In brain scans, learning that others thought well of you activated the striatum, the same reward area that lights up when people receive money.

What it means: to the brain, a real compliment is a real reward.

Izuma, Saito and Sadato, 2008, Neuron

It helps people learn

A compliment after practice helped people do better the next day.

People who were praised after learning a new finger-tapping skill performed it better the next day than people who weren’t.

What it means: say it while someone is learning, like a new hire in their first weeks.

Sugawara and others, 2012, PLoS ONE

We hold back too much

We underestimate how good our compliments make people feel.

Givers expected the other person to feel less happy, and more awkward, than they really did. Because we guess wrong, most of us say fewer compliments than we should, and the giver ends up in a better mood too.

What it means: the compliment you are thinking about will land better than you fear. Say it.

Boothby and Bohns, 2021, Personality and Social Psychology Bulletin; Zhao and Epley, 2021, Journal of Personality and Social Psychology

At work

One thank-you, 50% more calls.

At a university fundraising call center, callers who got a short thank-you from the director made more than 50% more calls the next week. In another study, people who were thanked were twice as likely to help again.

What it means: gratitude from the person in charge changes effort.

Grant and Gino, 2010, Journal of Personality and Social Psychology

For kids

Praise the effort, not just the talent.

Children praised for their effort chose harder puzzles and kept trying longer than children praised for being smart.

What it means: “You kept going on that hard problem” beats “You’re so smart.”

Mueller and Dweck, 1998, Journal of Personality and Social Psychology

It spreads

Kindness passes from person to person.

When people were treated generously in a group game, they gave more to others later, and the effect spread to people up to three steps away.

What it means: your compliment can reach people you will never meet.

Fowler and Christakis, 2010, Proceedings of the National Academy of Sciences

What we don’t claim

Honest numbers only.

You will sometimes see a claim online that a weekly compliment raises productivity by 30 to 35%. That figure is not supported by the recognition research, and we don’t use it. The numbers above are strong enough. Don’t let anybody quote you a bigger one.

How to read these numbers

Most workplace figures are correlations and models across very large groups. They are not a promise about your specific team. Recognition on its own won’t fix low pay, a broken schedule or a bad supervisor. What it will do is stop you losing people you could have kept, and it costs nothing to try for thirty days.
