Firms promote primarily on current-role performance: in personnel data on 38,843 sales workers at 131 US firms, doubling a worker's relative sales raises the monthly probability of promotion by 0.074 percentage points (a 32% increase over the base rate), and independent establishment data likewise find relative performance determines promotions.

Counter-evidence searched: Searched 2026-07-07 for evidence that firms instead promote on assessed potential: Benson, Li & Shue (2026) show explicit potential ratings do drive promotions where 9-box-style systems exist — but those ratings are themselves miscalibrated, refining rather than contradicting the finding that precisely measured current output dominates. DeVaro (2006, RAND JE) independently corroborates relative-performance-based promotion.

Among promoted sales workers, pre-promotion performance negatively predicts managerial performance: doubling a new manager's pre-promotion sales predicts a 6.1% decline in each subordinate's sales growth, roughly one-third of one worker's output on a typical five-person team.

Regression to the mean guarantees that workers promoted for crossing a performance threshold look worse afterward under any promotion rule, and lab experiments confirm the decline when transitory ability variance is large — but this mechanism does not explain the negative cross-sectional relation between pre-promotion sales and managerial value added, which survives explicit mean-reversion controls.

The claim text integrates both.

Promotion functions as a tournament prize with measurable incentive value: rank-based prizes induce efficient effort in theory (for risk-neutral workers), in a field experiment a 10% upward revision in perceived manager salary raised employees' subsequent hours worked by 1.5% (elasticity 0.150), and structural tournament estimates on establishment data support workers being motivated by larger promotion wage spreads (at the 10% significance level) — though no study yet prices the effort a specific promotion rule buys against its measured match cost.

Genuine limits that keep this claim at moderate: the structural support clears only the 10% bar on one cross-section; and in the Cullen–Perez-Truglia experiment effort inputs moved while measured output did not (sales elasticity 0.106, p = 0.383). No study yet measures the effort a specific promotion rule buys on the same ledger as the −6.1%/+30% match cost.

Promoting to maximize predicted managerial quality instead of current sales would raise average manager value added by about 30% in the same data — a cost the study's authors interpret as what firms may knowingly pay for promotion-based incentives, not proof of mistaken beliefs.

The 'knowing tradeoff' interpretation is an inference — no study observes executives pricing the 30% managerial sacrifice against a measured effort gain, so 'firms are simply mistaken' remains live.

Firms behave as if they understand the incentive-versus-match tradeoff: where managerial mismatch is costlier (larger supervisory teams) they weight sales less and collaboration more in promotion decisions, and where strong pay-for-performance provides an alternative incentive they also weight sales less — yet pay for performance does not eliminate the Peter Principle pattern.

  “Consequently when told that they have been selected for promotion to a technical ladder position, such a person hears a very different message. He hears that the organization does not think that he will make a good manager. The technical ladder promotion then becomes a consolation prize, and very often de-motivates an otherwise productive member of the staff.”

  “Responses indicate marked age-dependent differences in response, particularly a strong increase in the proportion preferring more interesting project work over either form of advancement.”

  career-preference distribution among classifiable respondents: 45.8% preferred interesting project work vs 32.6% managerial ladder and 21.6% technical ladder (n = 1,495 classifiable of 2,157 usable questionnaires, nine US organizations)

Counter-evidence searched: CORRECTED in the r1 revision (2026-07-07): the seed-report line attributing 'managerial delusion' to the authors as a verdict was removed — the phrase appears only in the paper's title, as a question, and the prestige-parity point is the authors' introductory framing, not a survey finding. What the survey actually found cuts two ways and both are now recorded verbatim: the consolation-prize framing supports the prize-leakage failure mode, while the headline age-dependent preference for interesting project work over EITHER ladder contradicts the premise that a second ladder is what technical staff want. Held at suggestive — theoretical support for the mechanism, preference (not outcome) data from the 1980s, and no Benson–Li–Shue-grade outcome study of dual tracks exists.
