A client of mine — a senior executive at a global, well-known industrial company — has become something of a legend inside his organization. He can align a big team like almost no one I’ve worked with. He executes at a level that gets him talked about in rooms he isn’t in. Hundreds of people report to him, in one form or another, and by every account they respect him, trust him, and work hard for him.

He’s now being considered for a seat in the executive suite. And the one piece of feedback that keeps surfacing — from people who admire him — is that he might be too kind. Too patient. Too forgiving.

Here’s what that looks like in practice: something gets dropped in the weeds of a big, complex operation, and instead of pushing the person responsible to pick it back up, he quietly pulls it into his own hands and fixes it himself. Every time. Because he is, genuinely and to his core, dedicated to doing right by his people and his company.

He asked me a version of a question I hear often, in different clothes: Can I be a kind, thoughtful human being and still succeed at the highest levels of corporate America?

Fair question. We’ve been taught, mostly without saying it out loud, that kindness and rigor sit on opposite ends of a dial — turn one up and the other has to come down. Soft leaders are nice. Hard leaders get results. Pick a lane.

I don’t buy it. And, more usefully, neither does the research.

Two kinds of service

Sometimes we believe we’re serving people by giving them a hand — forgiving the mistake, absorbing the miss, quietly fixing what went wrong so no one has to sit with the discomfort of it. I agree. Sometimes that is the kind thing to do.

But I’ve come to believe something else just as strongly: we also serve people — deeply — by holding high standards, operating with rigor, expecting a lot of them, and then getting out of the way and letting them rise to meet it. Kindness and rigor don’t have to compete. In the best leaders I know, and in the research, they aren’t opposites at all. They’re a combination — it’s not either being human or being tough; it’s both.

What the research actually says: Challenge and care are the best recipe

Start with clarity itself. Gallup’s long-running engagement research finds that only about half of workers strongly agree they know what’s expected of them at work. Yet employees who say their manager helps set clear performance goals are nearly eight times more likely to be engaged than those who don’t — and highly engaged business units run 21% more profitable, 17% more productive, with 41% less absenteeism. Expectation, it turns out, isn’t the opposite of care. It’s a form of it.

Then there’s the durability of the goal itself. Locke and Latham’s goal-setting research — among the most replicated findings in organizational psychology — shows that specific, difficult goals outperform vague “do your best” targets in roughly nine out of ten studies, across decades of lab and field work. A concrete, demanding target beats gentle encouragement almost every time.

Zenger and Folkman’s “Tent Leadership” research puts a number on the combination itself. Leaders who scored high on both Results Focus and Interpersonal Skills had an 82% likelihood of being rated top-tier by their own teams. Leaders who were strong in only one of those two dimensions — just one — had an 8 to 9% chance. Warmth without rigor, or rigor without warmth, barely moves the needle. Together, they’re transformative.

Amy Edmondson’s work is probably the most misunderstood research on this list. Psychological safety gets flattened into “make people comfortable,” but her actual framework is a 2×2 of psychological safety and performance standards. High safety with low standards is the Comfort Zone — people feel good, but they don’t grow. High standards with low safety is the Anxiety Zone — people hide mistakes and quietly burn out. Only when both high standards and safety are present do you get what she calls the Learning Zone, where teams do their best work. Comfort isn’t the goal. Learning is. And learning requires both halves.

And finally, there’s the felt experience of it. Mihaly Csikszentmihalyi’s research on flow found that people report their highest satisfaction not when work is easy, but when a challenge is matched to — and slightly stretches — their skill. We don’t come alive doing what’s comfortable. We come alive doing what’s hard and discovering we can.

What this means for us as leaders

Our job isn’t to make work easy. It’s to move people toward their highest possible contribution while genuinely supporting their growth along the way. Those two things aren’t in tension — they’re the same job.

When we set high standards, build real rigor into the work, and expect big things, people don’t just perform better. They tend to be more engaged in the work itself. They find more meaning in it. And, often, they deliver above and beyond whatever the job description said.

Think about what you actually remember from your own career. Not the days that were easy. The moments you accomplished something you weren’t sure you could — the projects that stretched you further than you expected to go. We remember the bosses who saw what we were capable of and expected it of us, even before we expected it of ourselves. We’re proudest of the things that once felt out of reach.

That’s the gift of accomplishment. It’s not something we hand people. It’s something we make room for them to earn — by believing they’re capable of more, and then asking for it.

So consider: where in your work have you quietly let up? Where might your team be better served by a more audacious goal than the safe one you’ve settled for? And where are you still operating as if kindness and high expectations can’t coexist — when the evidence, and probably your own best memories, say otherwise?

As for my client — the man hundreds of people would follow almost anywhere — here’s where we landed: The kindest thing he can do isn’t stepping into the weeds to fix what someone else dropped. It’s telling them, clearly, that he knows they can carry it — and then letting them prove him right. That’s not permission to stop caring. It’s caring enough to expect more.
