The Ladder That Grew Its Own Rungs

Laurence Peter and Raymond Hull published this in 1969 as a joke with footnotes — "hierarchiology," a mock-discipline invented to explain why every competent person eventually lands in a job they cannot do. The edition on the shelf now is not that book. It has grown a second half: a summary of a 2010 computational study by Pluchino, Rapisarda, and Garofalo, which ran Peter's hypothesis through an agent-based simulation and won an Ig Nobel Prize for confirming, mathematically, that organizations perform better when they promote their worst employees at random rather than their best deliberately. A satire has acquired a bibliography. The book didn't stay a diagnosis; it became a research program that verified its own punchline.

That accretion is worth sitting with, because it tells you what happened to the idea in the fifty-seven years between the joke and the simulation. Peter's insight — that competence at one level tells you nothing about competence at the level above it — got absorbed into corporate vocabulary with unusual speed and unusual literalness. By the 1970s, IBM and AT&T had built formal "dual ladders," parallel promotion tracks that let a skilled engineer keep climbing without ever being handed a team to manage. Tech companies now run entire taxonomies — senior engineer, staff engineer, principal, distinguished — built for the sole purpose of letting people who are good at the work stay in the work. This is a genuine structural response to a satirical diagnosis, which makes it an odd case: most of the books in this collection that name a systemic failure watch the failure get renamed and continue; this one got a policy.

But the policy only patches half the problem, because Peter's model assumes something that no longer holds for a large share of the workforce it claims to describe: a stable pyramid with fixed rungs. The book itself flags this weakness, almost apologetically, noting that "companies are currently much more flexible organisations that work from a project or network." What it couldn't see from 1969 is how thoroughly that flexibility would dissolve the ladder rather than fix it. Gig platforms don't promote anyone to their level of incompetence — there is no level, no rung, no ratchet holding you in place once you've risen too high. There is a score, continuously updated, and when it drops you are deactivated, not stuck. The disease Peter named was stasis: a person frozen in a job too big for them, protected by tenure and job description. The disease the platform economy produces is the opposite — nobody is ever frozen anywhere, because nobody has a position stable enough to be frozen in. Precarity replaces the ratchet effect; it doesn't refine it.

What the Ig Nobel Prize did, structurally, was take a piece of institutional cynicism and hand it back to institutions as a validated finding — comedy laundered into methodology, complete with peer review. It's a strange mirror of a pattern this collection keeps running into, where satire becomes usable design rather than warning, except here it happened with a wink built in from the start, the prize itself a joke about how seriously we take jokes. Which leaves an open question that the book, in either of its two forms, never quite answers: once an institution can cite a peer-reviewed study proving that promoting its worst people is the mathematically optimal strategy, has hierarchiology become a discipline, or has ridicule simply found a way to keep itself employed?
