Leader Humility Predicts Team Performance. Most Companies Never Develop It.

Leadership development budgets go toward building presence, confidence, and decisiveness. Those are real skills. They’re also not where the team performance research keeps pointing.

A 2022 systematic review covering 212 studies on leader humility, published in The Leadership Quarterly, found that humble leadership is among the strongest predictors of team performance and follower satisfaction across dozens of organizational contexts (Chandler et al., 2022). The analysis found it’s most strongly associated with participative decision making and how followers feel about working with the leader. Humble leaders draw more of the team’s actual knowledge into decisions.

‘Expressed humility’ is the observable, behavioral form of this trait: openly acknowledging your own limitations and mistakes, crediting others’ contributions in concrete terms, and staying genuinely curious about what your team members know that you don’t. The foundational research from Owens et al. (2013), drawing on eight lab and field samples, showed that these behaviors predict individual performance, team learning orientation, employee engagement, and retention. The key word is expressed: humility that stays private produces nothing measurable.

The Mechanism Most Programs Never Name

The research keeps returning to a specific dynamic: team silence. A 2024 study across five empirical investigations found that humble leadership negatively predicts team silence, and that team silence itself mediates the relationship between leader humility and team performance (Zettna et al., 2024). When leaders don’t model humility, teams hold information back.

Teams hold information back for a specific reason: the social cues around them suggest that speaking up, especially to challenge or correct something, carries more risk than staying quiet. That slow, invisible cost rarely gets diagnosed as a leadership problem. It shows up as cautious decisions, missed early warnings, and retrospectives where someone knew but didn’t say it.

The same research found the effect is strongest in teams with high organizational commitment, which is worth a moment’s thought. The team members most invested in the organization are also reading their leader’s behavior most carefully for signals about whether candor is actually welcome. Humble leaders compound what’s already good in a team.

I’ll admit this is a finding I initially found uncomfortable. Most leadership frameworks I’ve encountered treat confidence as the foundation and everything else as secondary. The humility research doesn’t argue against confidence; it argues that leaders who acknowledge what they don’t know, and do it visibly and consistently, create conditions for their teams to outperform leaders who project certainty as a default.

What This Changes About How You Develop Leaders

Start with a diagnostic before redesigning anything. Look at how your organization defines leadership effectiveness. If the primary output of your development programs is ‘executive presence’ or ‘confident communication,’ the program is probably optimizing for audience impressions rather than team output.

The Chandler et al. (2022) analysis found humble leadership predicts participative decision making more strongly than almost any other leadership behavior reviewed. That’s the behavior that routes information into decisions, not the one that projects certainty about decisions already made.

Use observer data rather than self reports. The Owens et al. (2013) research built observer report measures specifically because self assessment on this dimension is unreliable in both directions: leaders who express genuine humility tend to underestimate it, and leaders who project overconfidence tend to overestimate it. If your 360 tools don’t include subordinate and peer ratings of whether a leader credits contributions, acknowledges gaps, and genuinely invites challenge, you’re measuring something different from what you think.

Model the behavior explicitly at the leadership level. The humility effect documented in Zettna et al. (2024) operates through social contagion: leaders who publicly say what they don’t know, credit team members by name for specific contributions, and ask real questions in meetings give their teams permission to do the same. That permission structure doesn’t transfer through a policy or a training deck.

Add team silence as a diagnostic question in your leadership reviews. Ask your managers: in the last month, what have you heard from your team that surprised you or changed your thinking? When the answer is ‘not much,’ the more useful follow-up is whether the leader’s daily behavior has made candor feel worth the risk.

---

The broader pattern across those 212 studies is that humble leadership works most powerfully at the team level, not the organizational one. That’s the level where most leadership development actually operates, and it’s where most programs are currently investing in the wrong qualities. If team performance is what you’re building toward, the research suggests treating expressed humility as the starting point rather than the finishing touch.

What would shift in how your organization develops leaders if expressed humility were treated as the core, rather than a soft skill to address later?

Frequently Asked Questions

What is ‘expressed humility’ in leaders?

‘Expressed humility’ is the observable, behavioral form of leader humility, covering three specific practices: openly acknowledging your own limitations and mistakes, crediting team members’ contributions in concrete terms, and remaining genuinely curious about what others know that you don’t. Owens et al. (2013) established that this visible, practiced form of humility, rather than privately held modesty, is what produces measurable outcomes for teams. The behavior matters because it functions as a social signal to everyone observing the leader.

Does humble leadership make leaders less decisive?

The research doesn’t support that reading. The Chandler et al. (2022) meta-analysis found humble leadership predicts participative decision making, meaning decisions that incorporate more information, not slower or weaker ones. Leaders who acknowledge what they don’t know tend to reach decisions with better inputs. The issue is often cultural: many organizations read visible uncertainty as weakness rather than as a useful posture for gathering information before deciding.

Why does humble leadership affect teams more than whole organizations?

The mechanism runs through dynamics at the team level: team silence, psychological safety, and information sharing. These operate at the level of the immediate work group and are most directly shaped by the daily behavior of whoever leads that group. Organizational performance reflects many variables that a single leader’s humility can’t reliably move, including strategy, market conditions, and macro factors. The effect at the team level is where the research is consistent and actionable.

How do you measure expressed humility if self reports don’t work?

Observer reports from peers and direct reports are more reliable than leader self reports. The Owens et al. (2013) research found self assessment on humility is systematically unreliable in both directions. 360 feedback tools that include subordinate and peer questions about whether a leader credits contributions, acknowledges gaps, and genuinely invites challenge give you the most validated picture available.

What’s the connection between humble leadership and team silence?

Zettna et al. (2024) found that leader humility reduces team silence, and that team silence mediates the relationship between leader humility and team performance. When leaders model humility, they signal that candor is welcome, which reduces the tendency for team members to withhold useful information, concerns, and corrections. Teams with high organizational commitment are particularly responsive to this signal, making humble leadership especially valuable in engaged teams.
