Cognitive debt, capability debt, and the rest

Five terms for one worry, published within twelve months of each other. What each one means, what the evidence under it actually is, and the finding that emerged from checking: almost nobody claims to have coined any of them.

Last reviewed: 28 August 2026

A map of the competing vocabulary for AI and capability loss, read at primary source, with coinage claims tested rather than assumed and three unverifiable sources named and excluded.

Cognitive debt, capability debt, epistemic debt, culture debt, distributed de-skilling. Five terms, published between June 2025 and June 2026, for versions of the same worry: that using AI well in the short term costs something that only shows up later. This page maps them. The finding that came out of doing so was not the one expected. Almost nobody claims to have coined any of them.

Every source in this map was read at the primary source

The terms below were checked against the paper or the publisher's own page, not against summaries. Where a source could not be reached, it is named at the foot of this page and left out of the map rather than described from secondary coverage. Three sources fell into that category, and one of them would have supported a point this page would otherwise have liked to make.

The debt family, and who actually claims what

A coinage claim is a specific thing. It reads "we introduce", "we term", "we propose the term". Using a phrase, even defining it carefully, is weaker than claiming it. That distinction turns out to matter more than the terms themselves.

The actual finding: convergent metaphor, no shared lineage

Rohde, Sankaranarayanan and Deloitte each reach for a debt metaphor within four months of each other. None of them cites either of the others. Three separate authors, working in organisational economics, computing education and human capital consulting, independently arrived at the same accounting figure for the same phenomenon.

That convergence is more interesting than any individual coinage would have been. It suggests the metaphor is doing something the field genuinely needs, which is to describe a cost that is incurred now and paid later, invisible on any current measure. It also means the question "who said it first" is close to unanswerable and probably not worth answering.

What the most-cited term actually rests on

Cognitive debt is the term that reached the public. The study underneath it deserves reading rather than citing.

Fifty-four participants, aged 18 to 39, recruited from five universities in the Boston area, writing essays across three sessions. Three groups of eighteen: one using ChatGPT, one using a search engine, one unaided. EEG on 32 channels. The finding most quoted, that removing AI left the LLM group unable to quote their own work, comes from session four, which only 18 participants attended, nine per arm. The widely repeated 78 per cent and 11 per cent are seven of nine and one of nine.

The paper still carries "Preprint, under review" in the footer of all 216 pages of its December 2025 revision. It has not been peer reviewed. The authors state their own limits clearly, including that findings "are context-dependent and are focused on writing an essay in an educational setting and may not generalize across tasks", and they hedge the central passage themselves: "This next finding should be considered preliminary, as a larger participant sample is needed to confirm the claim."

On 29 December 2025 a formal Comment was posted by Stanković and colleagues at Vienna and TU Dresden, arXiv 2601.00856. Their power analysis puts the required sample at roughly 159. Their sharpest point is about the term itself: the search engine group used an external tool and showed no impairment, with the comparison against the unaided group returning p = 1. If offloading to a tool produced cognitive debt, that group should have shown it. The Comment is also a preprint, offered as a critique rather than a refutation.

None of this makes the study worthless. It makes it a small, unreviewed, contested pilot carrying a term that a great deal of subsequent commentary treats as settled.

What the most influential survey rests on

BCG's June 2026 article will be quoted in boardrooms for the rest of the year, and its headline numbers are worth reading with their provenance attached. Seventy C-suite leaders and senior executives. Half already observing de-skilling. More than 60 per cent expecting it to be a material threat within three to five years. Judgement and decision-making named as carrying the highest de-skilling risk.

The article states no countries, no fieldwork dates, no sampling method, no response rate, no industry breakdown and no question wording. It has no limitations section, no endnotes and no reference list. A "de-skilling risk score" is reported as though it were a defined metric and is never defined. By the grading used across this estate, that places it as an institutional survey of unknown representativeness, useful as a signal of what senior people now believe and not usable as a measurement of what is happening.

The same applies to Deloitte's March 2026 release, which reports that 85 per cent of leaders call adaptability critical while 7 per cent say they are leading on it, and gives no sample size, no countries and no fieldwork dates in the release itself.

The pattern across all three is the same. The vocabulary is ahead of the evidence, and the evidence is ahead of its own methodology sections.

Where this research sits, stated against itself

This estate uses capability debt. It makes no claim of first use, and the check above is the reason it never will: Rohde defines the term in print and does not claim it either, so the honest description is that two people arrived at an obvious metaphor for the same problem at roughly the same time, along with several others who reached for adjacent versions.

The same standard applies to the rest of the vocabulary here. Usage theatre and the verifier's discount carry no first-use claim. Synthetic seniority and the missing rungs do, and are dated. Applying to your own vocabulary the test you apply to everyone else's is the cheapest credibility available, and most of the sources on this page do not do it.

One further observation, offered as an impression rather than a measurement. The academic terms describe what happens inside an individual head: cognitive debt, epistemic debt, the verification bottleneck. The consulting terms describe what happens to an organisation: distributed de-skilling, culture debt. The gap between those two is where the mechanism lives, at human capability in the age of AI. It stays thinly occupied because working there needs both literatures at once.

Adjacent terms worth knowing

What could not be verified, and is therefore absent

Three sources were pursued and left out.

Naming these is the point rather than an apology. A map of who said what, built partly from search summaries, would be a map of what search engines believe.

For the category these terms are circling, human capability in the age of AI. For the mechanism, capability debt, the missing rungs and synthetic seniority. For how sources are graded here, the evidence base and what we actually know. For the oversight argument, human in the loop is not a safeguard.

About this research

Rahim Hirji is the author of SuperSkills (Kogan Page, 2026), keynote speaker on AI and human capability, and founder of The SuperSkills Intelligence Company. Every source on this page was read at the primary source on 28 August 2026, with the three exceptions named above. Coinage claims were tested by searching each paper for explicit claiming language rather than by inference from usage. This page describes other people's work and has an obvious interest in one of the terms on it, so the standard applied to everyone else has been applied here first.
