It’s that one decision Buffett says you can’t afford to ignore.
Integrity is such a non-negotiable aspect of Warren Buffett’s business practice that he vows the key to success is to associate only with people who possess it. He once said:
“If you’re going to get someone without integrity, you want them lazy and dumb.”
It’s a bit blunt, but he’s making a sharp point. A person who’s smart and driven but lacks integrity can do real damage. They might use their talents to manipulate situations or people for personal gain, rather than working for the good of the team or the mission.
That’s why leaders can’t just look for skill, creativity, or ambition in others.
Success and integrity are joined at the hip
There’s a dangerous myth in leadership that results alone define success. But if those results are achieved by cutting corners, betraying trust, or stepping on others, the “success” won’t last—and neither will your reputation.

The most respected leaders understand this. Think about:
- Satya Nadella (Microsoft): Turned a cutthroat, internal competition-driven culture into a collaborative powerhouse, proving that trust and empathy can drive innovation and profits.
- Indra Nooyi (PepsiCo): Made “Performance with Purpose” a core strategy, aligning the company’s growth with social responsibility and ethical practices.
- Howard Schultz (Starbucks): Built brand loyalty not just on coffee, but on a culture of fairness, community, and doing right by employees.
In each case, integrity wasn’t a “nice to have,” it was a growth strategy. These leaders played the long game, knowing that when people trust you, they’ll follow you further, work harder, and stick around longer. It’s great for retention and also great for building a high performing work culture.
Speaking of culture…
Protect your culture
You’ve worked hard to build a culture of integrity and fostering an environment of honesty and transparency, where your workers “do the right thing” (even when nobody’s looking). Now comes the hard part: How to protect your culture from violators. It comes down to building systems and habits that keep your team’s moral compass steady. Here are a few ways to do it:
1. Screen for character, not just competence
During interviews, go beyond the résumé. Ask about ethical dilemmas they’ve faced. Listen for humility, ownership, and long-term thinking.
2. Promote trust as a performance metric
Reward employees not just for what they achieve, but how they achieve it. Make collaboration, transparency, and accountability visible in your recognition systems.
3. Act quickly when integrity is breached
Nothing erodes trust faster than watching a leader tolerate unethical behavior because “they get results.” The team notices—and they’ll either follow suit or walk out.
4. Model what you expect
Leaders set the tone. Your decisions, even in small moments, tell people whether honesty is truly valued or just a slogan on the wall.
Looking back, Buffett’s initial advice might sound tongue-in-cheek, but it’s deadly accurate: never trade integrity for good talent. Skills can be taught. Drive can be inspired. But if a person’s moral compass is broken, you’re better off without them—no matter how impressive they look on paper. Because in leadership, as in life, character isn’t just the first thing. It’s everything.
