The best salespeople promoted systematically become bad managers.
This isn’t an opinion. It’s empirically documented by Alan Benson, Danielle Li and Kelly Shue in Quarterly Journal of Economics in 2019. On 53,798 salespeople in 214 American companies. Rigorous validation of what Laurence Peter theorized in 1969: the Peter Principle.
Here are 8 statistics 2026 that quantify the mechanism. If you went from “creative lead” to “creative team manager” and you wonder why you hate your new role, these numbers explain what your inner coach can’t formulate.
The Peter Principle in 1 sentence
Laurence J. Peter and Raymond Hull, The Peter Principle (1969). Original formulation: “In a hierarchy, every employee tends to rise to their level of incompetence”. In other words: organizations promote people until they can no longer do the job. And they stay at that position, by acquired incompetence.
For 50 years, the Peter Principle remained a popular intuition but poorly empirically validated. Benson, Li & Shue (2019) changed that with a massive and rigorous study.
The 8 key statistics
1. Sales performance doesn’t predict managerial performance
Benson, Li & Shue study (2019). On 53,798 salespeople tracked over 6 years, the correlation between performance before promotion (as IC) and performance after promotion (as manager) is negative or zero. The best salespeople don’t become the best managers. They often become the worst.
2. Promoting the best salesperson reduces team performance by 6%
Measured in the same study. When the organization promotes the top performer as manager, the average performance of their team drops by 6% over the following 12 months. It’s mechanically counter-productive, but it’s the dominant promotion pattern.
3. Yet it’s the #1 promotion criterion (used in 80% of cases)
Organizations promote 80% based on past technical performance, not on the evaluation of managerial skills. It’s easier to measure (sales figures, deliverables, metrics). But it’s not relevant for the target position.
4. Creative industries are particularly exposed
VFX, gaming, design, agencies. The Peter Principle is amplified there because the “natural” career path is: junior artist → senior artist → lead → supervisor → manager. This pipeline forces managerial promotion, even when the artist would be better off staying senior IC or pivoting freelance.
5. Cost to the organization: 4 to 8% of payroll
2020-2024 economic estimates. A typical organization loses 4 to 8% of its payroll due to the Peter Principle (underperformance of badly promoted managers + underutilization of the potential of good ICs who should have stayed IC + disengagement of badly managed teams).
6. Personal cost: silent burnout or external resignation
The badly promoted manager finds themselves in a position where they unconsciously know they’re less competent than before, but they can’t go down (loss of face) or move forward (lack of skills). They develop an amplified imposter syndrome, a boreout (management doesn’t feed them like the IC role did), or a burnout within 3-5 years following the promotion.
7. Competence in one domain doesn’t predict competence in another
That’s the underlying principle. Making films isn’t managing a team that makes films. Coding isn’t directing a team that codes. The two skills look superficially similar but are neurologically distinct (one mobilizes creation, the other mobilizes interpersonal coordination).
8. The validated solution: the “double track” (technical + managerial)
Companies that offer two promotion paths (stay senior IC expert OR move to manager) reduce the Peter Principle by 60%. But only 25% of creative companies offer this double track. In 75% of cases, the only visible progression is managerial.
Apply to your situation
If you went from senior IC to manager in the last 5 years, and you wonder if you shouldn’t have stayed IC, you’re not alone. The Peter Principle probably concerns you.
3 diagnostic questions:
- Do you now spend 70%+ of your time fixing other people’s problems, without producing anything yourself?
- Do you tell yourself “I never wanted to manage, I wanted to make”?
- Do you secretly envy the senior ICs who refused the managerial promotion?
If you answer yes to 2 or 3, the Peter Principle is your main lock. The exit isn’t to “become a better manager” (managerial training has limited effect when the needs wiring doesn’t match the role). The exit is to step back to senior IC, or to pivot laterally.
