Why Too Much Leadership Drive Can Hurt Sales Performance
In a study of 10,765 insurance agents, leadership drive followed an inverted-U. Production rose from the lowest leadership quartile at 28.4% to the third at 36.5%, then dipped at the highest quartile to 35.9%. Moderate leadership drive outperformed extreme leadership drive. A likely reason: agents with the strongest drive may resist the structured coaching and scripted processes the role requires. A single behavioral trait can help up to a point and then start working against you.

The inverted-U
Production rate by leadership score quartile:
| Leadership quartile | Production rate |
|---|---|
| Q1 (lowest) | 28.4% |
| Q2 | 34.1% |
| Q3 | 36.5% |
| Q4 (highest) | 35.9% |
Production climbed with leadership drive, peaked in the third quartile, then fell back in the top quartile. More drive helped, until it did not.
Why extreme drive can backfire
In a structured sales environment with required coaching and scripted processes, the agents with the strongest leadership drive may be the least willing to follow the system. They push their own approach, resist the playbook, and lose the benefit the training was designed to give. This is the same coachability theme that shows up with experienced hires, where prior habits get in the way of adopting a new process.
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 always. In this study, production peaked at moderate-to-high leadership drive and dipped at the very highest levels, an inverted-U.
Why would strong leadership drive hurt sales? In a role with required coaching and scripted processes, the strongest-drive agents may resist the system and revert to their own approach, losing the benefit the training provides.
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.
