The traits that make someone appear commanding in a room do not always translate into team performance. Visibility and vocal confidence can create an impression of leadership before any work has begun, yet the actual results depend heavily on the composition and behaviour of the group itself.
In 2011, Adam Grant, Francesca Gino and David Hofmann published research showing an important interaction. Leaders who were more outgoing achieved stronger outcomes with relatively passive teams, whereas those who were less outgoing performed better when their employees took initiative. The mechanism, the researchers proposed, was that quieter leaders' receptive demeanour encouraged proactive workers to invest greater effort.
A crucial detail often overlooked in retellings: the less-outgoing leaders did not succeed by implementing more of the suggestions they received. Rather, employees perceived them as open to input, and that perception alone drove higher performance even when the suggested idea itself was not adopted.
The field study: 57 pizza franchises
The research, published in the Academy of Management Journal, began with real-world data. Questionnaires went to 130 stores operated by franchisees of a US pizza-delivery chain. Fifty-seven stores returned complete responses, representing a 43.1 per cent response rate.
The final field sample included 57 store managers and 374 employees, averaging roughly 6.6 employee respondents per location. Managers self-assessed their Big Five personality traits, noting whether they tended toward assertiveness, talkativeness, boldness, reserve or introversion. Employees rated typical workplace behaviour among their colleagues, with proactivity measured across three dimensions: proposing ideas, taking steps to improve procedures and attempting to influence management.
Researchers then tracked each store's profitability over the following seven weeks. Statistical models controlled for average order value and labour hours—both strong predictors of profit—along with managers' other personality dimensions and their interactions with employee proactivity.
The crossover effect emerged clearly. In stores where employees showed low proactivity, manager extraversion correlated with higher profits. In stores with high proactivity, greater manager extraversion correlated with lower profits.
However, this was an observational association rather than a causal demonstration. Managers were not randomly assigned personalities, and unmeasured store differences could have influenced results. To test causation more rigorously, the authors designed a controlled laboratory study where leadership style and follower behaviour could be manipulated.
The laboratory: a T-shirt folding task
The second study recruited 163 university students with an average age just under 21, forming 56 groups. Each group consisted of one student leader, two regular student followers and two research confederates posing as additional followers.
The task was straightforward: fold as many T-shirts as possible within ten minutes. The most productive groups could win iPod Nanos, providing genuine motivation to perform.
Before the task, each leader read one of two brief scenarios. One emphasised bold, talkative and assertive leadership; the other highlighted quiet, shy and reserved leadership. Leaders then recalled a time when they had led successfully using the assigned style. This exercise shaped how extravertedly they behaved during the task, testing an enacted style rather than sorting participants by fixed personality type.
The two confederates followed a script. In the passive condition, they simply followed the leader's instructions. In the proactive condition, one questioned aloud whether a more efficient method existed, while the other suggested teaching the group a faster Japanese folding technique.
With passive confederates, teams under more-extraverted leadership folded an average of 167.93 shirts, compared with 137.64 under less-extraverted leadership. When confederates became proactive, the pattern reversed: teams with less-extraverted leaders averaged 175.43 shirts versus 142.00 under more-extraverted leaders. This interaction reached statistical significance.
The extra output came from followers, not leaders
The improved team totals could have resulted from quieter leaders folding more shirts themselves. They did not. When researchers separated leader output from ordinary follower output and excluded the confederates, leadership style and proactivity did not significantly affect what leaders personally produced. The difference originated entirely with the followers.
Under the proactive condition, followers working with less-extraverted leaders folded an average of 59.64 shirts, whereas those under more-extraverted leaders averaged 46.61. This contrast did not reach statistical significance when confederates remained passive.
Followers also rated leaders on whether they seemed open to new ideas, receptive to suggestions and interested in their contributions. With proactive confederates, less-extraverted leaders received an average receptivity rating of 5.35 on a seven-point scale, compared with 4.32 for more-extraverted leaders.
A mediation analysis suggested that these receptivity ratings accounted for the difference in follower performance. In simpler terms, proactive employees appeared to work harder when the leader's behaviour signalled that their input had been taken seriously.
Accepting ideas was not the mechanism
Perhaps less-extraverted leaders simply adopted the proposed folding method more frequently, allowing the entire group to work faster. The researchers tested this possibility and found no support for it.
Among proactive groups, 8 of 14 leaders in the low-extraversion condition accepted the suggestion (57.1 per cent), compared with 9 of 14 in the high-extraversion condition (69.2 per cent). This difference was not statistically significant and, if anything, numerically favoured the more-extraverted leaders.
Adoption of the method itself also failed to significantly boost output. Followers whose leader accepted the method folded an average of 161.82 shirts as a group, versus 156.60 when the leader rejected it. The ten-minute timeframe left insufficient opportunity to recover the costs of teaching and learning a new technique.
The implication is nuanced. Receptivity differs from agreement. A leader can listen carefully, pose questions and give an idea serious thought before concluding it will not work. Conversely, a leader can approve a suggestion while conveying impatience or indifference.
Employees often gauge from such interactions whether proposing the next idea carries acceptable social risk. A decision of "no" can still communicate, "your judgement has a place in this room."
Feeling valued is interpretation, not direct measurement
The authors proposed a motivational pathway. When employees sense that a leader values their contributions, they may feel obliged to contribute and believe their effort will matter. When a leader appears dismissive, that motivation can erode.
This reasoning underlies descriptions of receptive leaders as making employees feel valued and work harder. It represents a plausible interpretation of the observed pattern, yet the measurement scope carries importance.
The experiment directly measured perceived leader receptivity and observable folding output. It did not separately measure whether participants felt valued, nor did it ask them to report their effort level. Greater follower output served as evidence of effort, while feeling valued formed part of the authors' theoretical framework.
The statistical mediation result strengthens the proposed pathway, but it does not transform every element of that pathway into a directly observed fact. Receptivity could also influence attention, coordination, comfort, confidence or some other unmeasured factor.
This is a matching principle, not a universal rule for quiet leaders
The study is frequently retold as a blanket endorsement of introverted managers. Its actual finding is conditional.
When followers were passive, the more-extraverted approach produced higher output. A reserved leader paired with a team awaiting direction represented one of the weaker combinations. When followers brought initiative, less-extraverted leadership allowed that initiative to flourish more fully.
The authors framed this through dominance complementarity. Assertive behaviour from both leader and employees can generate friction over status and control. Minimal assertiveness from either side can leave a group lacking momentum. Performance may improve when initiative from one side encounters receptiveness on the other.
This does not require viewing extraversion as a fixed, monolithic trait. A naturally talkative leader can develop the ability to pause, invite disagreement and demonstrate that suggestions have received consideration. A reserved leader can become more directive when a group requires clarity and forward movement. The laboratory manipulation itself showed that people could temporarily adopt a more or less extraverted style.
Nor does it mean every employee proposal deserves implementation. Proactivity can be poorly informed, self-interested or misdirected. The study tested a constructive suggestion with genuine potential to improve the task.
The evidence carries important limitations
Both studies focused on structured, repetitive, effort-based work: pizza delivery and shirt folding. The authors explicitly noted that the pattern might not generalise identically to difficult, complex or creative tasks, where knowledge and ability may dominate.
The field study examined a single company and relied on self-reported manager traits alongside employee ratings. Its 57-store sample was valuable but modest. The experiment involved young students, a ten-minute contest and an obvious scripted suggestion. An actual workplace with history, hierarchy and real career stakes creates a different social environment.
Additional context deserves mention. In a 2023 data-provenance disclosure, Grant stated that Gino conducted the second study and that he had never held its raw data. He indicated the laboratory data were undergoing audit. The Academy of Management continues to list the paper rather than issue a retraction. The disclosure does not prove the reported result is incorrect, but the lack of a public audit conclusion warrants caution.
The field and laboratory findings should therefore not be treated as a universal law of team design. They represent two studies supporting a specific interaction, with the laboratory evidence carrying an unresolved provenance qualification.
Receptivity shows itself before agreement
The practical takeaway is not to select leaders based on personality labels. Rather, examine the alignment between how leadership is expressed and how initiative flows through the team.
A hesitant team may benefit from someone willing to set direction, speak first and generate momentum. A team full of people who spot problems and volunteer solutions may need a leader capable of resisting the urge to turn every contribution into a competition for airtime.
That second skill becomes apparent in small actions. The leader permits someone to finish speaking. They ask a question before defending their own position. They can explain why an idea is being rejected without suggesting it was foolish to propose it. They acknowledge credit when another person's suggestion alters the plan.
None of these behaviours requires a leader to abandon sound judgement. They signal that employee voice has been processed rather than merely tolerated.
The person who breaks the silence is often the easiest to identify as a leader. Grant, Gino and Hofmann's work suggests that, for a proactive team, the more valuable skill may be recognising when to create enough silence for others to continue contributing.
