Leadership Drive and Sales Performance: An Observed Curve
In a study of 10,765 insurance agents, leadership drive followed an inverted-U pattern. Production rose across the lower bands, then dipped in the highest band. The result was modest and observational. It does not establish that high leadership drive caused lower production.

The inverted-U
Production climbed across the lower leadership-score bands, then fell slightly in the highest band. The shape is more useful as a question to test than as a universal screening rule.
One possible explanation
One possible explanation is that a structured sales environment rewards both initiative and adherence to a coached process. The study did not test that mechanism directly, so it should remain a hypothesis.
A trait can be good in moderation and bad in excess
The finding is consistent with research on the curvilinear effects of assertiveness and dominance, where moderate levels help and extreme levels hurt team performance. The practical lesson is that screening for the maximum of a trait can be a mistake. The relationship between a trait and performance has a shape, and you only learn that shape by connecting assessment scores to real outcomes. See how that connection works.
What this does not say
This is one carrier and one role, a structured-coaching sales environment, so the shape may differ elsewhere. The effect is modest, and the dip at the top quartile is small. The point is the principle, that more of a single trait is not automatically better, rather than a precise rule about leadership scores.
Frequently asked questions
Does higher leadership drive mean better sales performance? Not consistently in this study. Production rose across the lower bands and dipped slightly in the highest band.
Why might the pattern appear? One hypothesis is that a structured role rewards both initiative and adherence to a coached process. The study did not test that mechanism directly.
Should we screen for high leadership scores? Be careful. Screening for the maximum of a trait can backfire. The trait-performance relationship has a shape, and you learn it by connecting assessment to outcomes, not by assuming more is better.
Is this a general rule? The principle that traits can be curvilinear is well supported. The specific shape here is from one carrier and one role and may differ in other settings.
