LD-02 — AGGREGATE NULL OR DISTRIBUTIONAL SHIFT? EMPLOYMENT
Living Debate v0.2 — PUBLISHED
STATUS
Second version, repository-authored. It revises how this debate reads the two Danish studies (sections 3 and 8, the short answer, and the open questions). Revised by Claude (SocioLens Project Lead), an AI model made by Anthropic; not reviewed by a human domain expert. Version 0.1 stays available unchanged.
LAST UPDATED
17 October 2026
WHAT CHANGED IN v0.2
Version 0.1 said the two Danish studies "appear contradictory only if different labour-market margins are collapsed": one measured incumbent earnings and hours, the other firm recruitment, so both could be true.
That reading is weaker than v0.1 presented it. The March 2026 revision of Humlum and Vestergaard, which v0.1 already cited, also measures the firm margin. At workplaces that encourage chatbot use, it finds no differential change in workplace employment, in the early-career share of employment or in job churn through December 2024. Danmarks Nationalbank Working Paper 223 finds about 11% lower employment growth at firms that adopted AI in 2023, by late 2025.
The two studies differ in how adoption is measured, in the unit studied and in the time horizon, so they need not contradict each other. But neither the difference in margins nor any reconciliation SocioLens has read explains the gap. Version 0.2 therefore treats the Danish firm-employment evidence as an open tension, not as a settled stock-and-flow story.
Why: on 14 October 2026 SocioLens read the full text of the Humlum and Vestergaard revision; the claims v0.1 cites had been built from its abstract. Claims LD02-HQ-C02 and LD02-HQ-C03 were revised to v1.1 on that basis, and this version now cites those revisions. The full text was read again for this version on 17 October 2026.
What could not be checked: the Danmarks Nationalbank paper could not be opened for this revision (its website is not reachable from the environment SocioLens works in). Its figures here are those recorded in v0.1 and in claim LD02-HQ-C03, not re-read. Whether that paper discusses Humlum and Vestergaard is not known.
The evidence cut is unchanged: no source published after 25 September 2026 was added. Apart from the Danish passages and a misspelled heading, the text is the v0.1 text.
QUESTION
What are the early labour-market effects of generative AI?
Are they best described as:
• little aggregate employment change;
• displacement;
• productivity-led complementarity;
• distributional restructuring;
• or some combination that depends on which labour-market margin we measure?
SHORT ANSWER
The strongest early evidence is neither “mass displacement” nor “no effect.”
It is a margin-specific pattern:
• task-level productivity gains are large in selected workflows;
• short-run earnings and hours for incumbent workers can remain nearly unchanged;
• in Denmark, one register study finds weaker employment growth and recruitment at AI-adopting firms, while another finds no employment change at workplaces that encourage chatbot use; national aggregate employment remains comparatively stable;
• the strongest emerging displacement-like signal is at hiring and entry margins, especially for younger workers in exposed work;
• those entry effects are geographically heterogeneous and often exposure-based rather than direct measures of AI use;
• broad aggregate labour-market disruption remains difficult to detect.
The central question is therefore not:
“Did AI affect jobs?”
It is:
WHICH MARGIN MOVED — TASK PERFORMANCE, WAGES, HIRING, HEADCOUNT, OCCUPATIONAL COMPOSITION OR AGGREGATE EMPLOYMENT?
And before treating that movement as an AI effect:
WAS AI ACTUALLY USED, OR WAS THE STUDY MEASURING EXPOSURE?
EVIDENCE LANGUAGE
SocioLens distinguishes:
FACT — directly supported observation or study fact.
ESTIMATE — measured quantity whose design, denominator and period matter.
INTERPRETATION — synthesis across evidence.
UNKNOWN — unresolved empirical question.
A LEVEL-OF-ANALYSIS MAP
For LD-02, five levels must remain separate.
This is an LD-02 analytical scaffold, not a new Field Map layer.
TASK
Did AI change speed, output, quality or errors on a specific task?
WORKER
Did a worker’s earnings, hours, productivity or task mix change?
FIRM
Did adoption change productivity, recruitment, headcount or workforce composition?
OCCUPATION / ENTRY COHORT
Did vacancies, hiring, entry or occupational demand change?
AGGREGATE LABOUR MARKET
Did total employment, unemployment, wages or occupational composition shift at scale?
A positive result at one level does not automatically establish an effect at the next.
The same discipline applies to the treatment chain:
EXPOSURE
≠ ACCESS
≠ ADOPTION
≠ ACTUAL USE
≠ TASK PRODUCTIVITY
≠ FIRM PRODUCTIVITY
≠ LABOUR DEMAND
≠ HIRING
≠ EMPLOYMENT STOCK
≠ WAGES.
1. TASK PRODUCTIVITY GAINS ARE REAL — BUT BOUNDED
FACT + ESTIMATE
The strongest evidence for immediate productivity effects comes from workplace experiments and quasi-experiments.
CUSTOMER SUPPORT
In the final 2025 Quarterly Journal of Economics article by Brynjolfsson, Li and Raymond, a generative-AI assistant increased successfully resolved customer-support issues per hour by 15% on average in one large firm.
The gains were substantially larger among less-experienced and lower-skill agents.
This is strong evidence that AI can compress performance differences on particular tasks.
It is not evidence that the firm needed 15% fewer workers.
SOFTWARE DEVELOPMENT
In a 2026 Management Science article combining three company field experiments with 4,867 developers, access to an AI coding assistant increased completed tasks by 26.08% on average.
Less-experienced developers adopted the tool more and benefited more.
Again, the estimand is task output under assigned access.
It is not an employment estimate.
CONSULTING AND THE JAGGED FRONTIER
A preregistered experiment with 758 BCG consultants illustrates why “AI productivity” cannot be treated as one stable number.
Inside the tested capability frontier, GPT-4 users:
• completed 12.2% more tasks;
• worked 25.1% faster;
• produced roughly 30–34% higher human-graded quality.
But on a task outside that frontier, AI users were 19 percentage points less likely to give the correct answer.
The lesson is:
CAPABILITY FRONTIERS ARE JAGGED.
The same model can strongly improve one task and damage performance on another nearby task.
2. TASK PRODUCTIVITY IS NOT LABOUR DEMAND
INTERPRETATION
A task that becomes 20% faster does not imply:
• wages rise 20%;
• employment falls 20%;
• output rises 20%;
• or hiring falls 20%.
Productivity gains can be absorbed through:
• higher output;
• better quality;
• new tasks;
• worker learning;
• lower prices;
• organisational slack;
• reduced hiring;
• reassignment;
• or some combination.
The transmission must be measured rather than assumed.
Denmark shows how hard that measurement is.
3. DENMARK: QUIET INCUMBENT OUTCOMES, CONTESTED FIRM EMPLOYMENT
FACT + ESTIMATE
Two Danish administrative-data studies disagree about employment at firms that adopt AI.
HUMLUM & VESTERGAARD: INCUMBENT EARNINGS AND HOURS
Humlum and Vestergaard link large-scale chatbot-adoption surveys to Danish administrative labour records.
Across 11 AI-exposed occupations, they estimate precise null effects on earnings and recorded hours two years after ChatGPT.
Their estimates rule out effects larger than 2% over that horizon.
Yet workers and employers report substantial task reorganisation.
New activities include:
• content generation;
• AI oversight;
• AI integration.
Some adopters also move into higher-paying occupations where chatbot use is more relevant, but not at a scale large enough to shift average earnings.
HUMLUM & VESTERGAARD: WORKPLACE EMPLOYMENT
The same paper also tests the firm margin.
At workplaces that encourage chatbot use, through December 2024, it finds no differential change in:
• total employment (the text says total hours, the figure plots log employment; effects larger than 2% ruled out);
• the early-career share of employment (effects larger than about a third of a percentage point ruled out);
• monthly job churn (effects larger than 0.5% of employment ruled out);
• the hours and occupational mobility of incumbent workers.
Early-career employment did fall in several of these occupations in Denmark. The authors find that this decline is not driven by the workplaces that adopted chatbots.
DANMARKS NATIONALBANK: FIRM RECRUITMENT
A September 2026 Danmarks Nationalbank working paper estimates that firms adopting AI in 2023 had about 11% lower employment growth relative to comparable non-adopters by late 2025.
This is a relative employment-growth estimate, not an estimate that firms laid off 11% of their workers.
The main mechanism was lower recruitment rather than a wave of incumbent separations.
The effect was stronger among smaller firms, and accompanying Nationalbank analysis reports stronger effects for younger and more highly educated workers.
At the same time, economy-wide Danish employment remained relatively unaffected and no clear aggregate wage effect was visible.
SocioLens could not re-open this paper for version 0.2. These figures are as recorded in version 0.1.
INTERPRETATION + UNKNOWN
Version 0.1 read these results as answers to two different questions: incumbent earnings and hours in one study, firm recruitment in the other.
That reading does not hold on its own. Humlum and Vestergaard measure workplace employment and early-career hiring too, and find no change at adopters.
The studies do differ in ways that could matter:
• adoption: firm AI adoption in the Nationalbank paper; workplaces that encourage chatbot use, as reported by surveyed workers, in Humlum and Vestergaard;
• population: Danish adopting firms and comparable non-adopters in the Nationalbank paper; workplaces employing workers in 11 AI-exposed occupations in Humlum and Vestergaard;
• horizon: late 2025 against December 2024, so an effect that appeared during 2025 would fall outside the earlier study;
• firm size: the Nationalbank effect is concentrated in smaller firms.
None of these has been shown to account for the gap.
Humlum and Vestergaard's revision predates the Nationalbank paper. Whether the Nationalbank paper addresses it is not known to SocioLens.
STOCKS AND FLOWS MUST STILL BE SEPARATED.
But in Denmark, separating them does not by itself reconcile the evidence. Lower recruitment at Danish AI adopters is a contested estimate, not an established mechanism.
4. THE ENTRY MARGIN IS THE CURRENT FAULT LINE
INTERPRETATION
Across several US and UK studies, the most persistent displacement-like signal is not mass layoffs.
It is weaker entry and hiring.
The evidence is not equally causal or equally strong across studies.
But the recurring margin matters.
US PAYROLL DATA: THE “CANARIES” RESULT
ESTIMATE — DESCRIPTIVE, NOT CAUSAL
By June 2026, ADP payroll data showed workers aged 22–25 in highly AI-exposed occupations about 19% below the employment path of similarly aged workers in less-exposed occupations.
The divergence was driven mainly by reduced hiring rather than increased separations.
Experienced workers did not show the same pattern.
But the authors explicitly describe the result as descriptive rather than a clean causal estimate.
The gap:
• shrinks with education controls;
• sits against some pre-existing divergent trends;
• is stronger in ADP data than in national-survey benchmarks;
• and can be sensitive to specification choices.
The correct interpretation is not:
“AI caused 19% fewer young jobs.”
It is:
A LARGE YOUNG-WORKER DIVERGENCE HAS EMERGED IN HIGHLY EXPOSED US OCCUPATIONS, PRIMARILY THROUGH HIRING. THE PATTERN IS CONSISTENT WITH AN AI-RELATED EFFECT, BUT THE STUDY DOES NOT ISOLATE AI CAUSALLY.
US ADMINISTRATIVE DATA: EARLY-CAREER HIRING
ESTIMATE — WORKING PAPER / EXPOSURE-BASED
A US Census study using Quarterly Workforce Indicators finds an immediate and persistent decline in hiring of 22–24-year-olds in the most AI-exposed industry-state cells after ChatGPT.
Regression-adjusted employment in the most-exposed group fell 12% over 10 quarters.
The study identifies reduced hiring as the primary mechanism.
But treatment is industry exposure, not directly observed AI use.
The paper also has to contend with:
• COVID-era trend changes;
• macroeconomic shocks;
• monetary conditions;
• assumptions embedded in exposure indices.
This makes the study important but not a clean “AI caused −12%” result.
NEW GRADUATES
ESTIMATE — VERY RECENT WORKING PAPER
A September 2026 Census working paper finds that graduates from the most AI-exposed tenth of college majors experienced:
• a 5 percentage-point decline in initial employment;
• a 13% decline in initial earnings
relative to less-exposed majors.
Some of the earnings decline reflects movement into lower-wage sectors such as restaurants and retail.
This is consistent with entry disruption.
But it shares an author and administrative research infrastructure with the earlier Census study, so it should not be counted as fully independent replication.
5. A FALLING JUNIOR SHARE IS NOT THE SAME AS JUNIOR JOB DESTRUCTION
ESTIMATE + INTERPRETATION
A very recent 41-country working paper by Chandar and Klein Teeselink uses 1.25 billion job postings and 154 million employment records to study multinational affiliates.
It finds that affiliates inferred to have adopted generative AI became more senior-heavy.
By March 2026:
• junior workforce share was about 1.9 percentage points lower;
• senior employment was about 6.7% higher.
The estimated junior headcount decline was not statistically clear.
Because this working paper appeared only days before this page was locked, its exact coefficients should be treated as especially version-sensitive.
That distinction is essential.
JUNIOR SHARE CAN FALL BECAUSE:
• juniors fall;
• seniors rise faster;
• or both happen.
In this study, senior expansion is the dominant mechanism.
So “seniority bias” does not automatically mean “junior job destruction.”
6. UK EVIDENCE IS MORE DISPLACEMENT-CONSISTENT — BUT EXPOSURE IS NOT USE
ESTIMATE — WORKING PAPER
A UK study using differences in LLM exposure reports:
• total employment about 4.5% lower at highly exposed firms;
• junior employment about 5.8% lower;
• job postings in highly exposed occupations about 23.4% lower.
These estimates are more consistent with labour-demand contraction than the multinational-affiliate evidence.
But they are exposure estimates.
The study does not directly observe whether each firm or worker actually used generative AI.
That means the public claim must remain:
HIGHLY LLM-EXPOSED FIRMS AND OCCUPATIONS EXPERIENCED THESE DIFFERENCES.
Not:
AI ADOPTION CAUSED THESE DIFFERENCES.
7. NORWAY IS A REAL COUNTEREXAMPLE TO A UNIVERSAL “CANARY” STORY
ESTIMATE — DESCRIPTIVE
Norwegian register data provide one of the most useful disconfirming cases.
Across the full private-sector employment distribution through February 2026:
• employment in the most-exposed occupations increased about 0.1%;
• employment in the least-exposed increased about 0.3%.
For young workers, the difference across the full exposure quintiles is an imprecise zero.
This does not prove that no occupation-specific AI effects exist in Norway.
It does show that the US young-worker pattern is not yet a universal cross-country law.
GEOGRAPHY MATTERS.
8. FIRM-LEVEL EVIDENCE IS MIXED — AND THAT IS THE POINT
FACT + ESTIMATE
Several firm-level studies produce different answers because they study different forms of AI, different countries, different periods and different margins.
EUROPEAN FIRMS
A BIS working paper covering more than 12,000 firms finds instrumented AI adoption raises labour productivity by about 4% with no adverse short-run firm-level employment effect.
The gains are larger among medium and large firms and where firms make complementary investments in software, data and training.
This study measures broad AI adoption, not only generative AI.
US FIRM SURVEY
In the US Census 2026 AI supplement:
• 18% of firms reported using AI in a business function;
• 32% when weighted by employment;
• workers used AI in tasks at 23% of firms;
• 41% employment-weighted.
Among AI-using firms, 66% described their use as augmentation only.
Only 2% of firms self-reported AI-related employment decreases during the reference period.
This is valuable prevalence evidence.
It is not a causal estimate of how many jobs would have existed without AI.
DENMARK AGAIN
If the Nationalbank result holds, it shows why a firm-level null cannot be assumed everywhere.
Then some adopting firms can reduce recruitment even while:
• incumbent earnings remain stable;
• aggregate national employment remains stable.
But Denmark also has a workplace-level null: Humlum and Vestergaard find no employment, early-career or churn change at workplaces that encourage chatbot use. The Danish firm-level evidence is contested, not settled (section 3).
9. BROAD US AGGREGATES STILL LOOK QUIET
ESTIMATE — BROAD MONITORING
As of September 2026, Budget Lab monitoring does not find a clear broad US employment, unemployment or occupational-mix footprint attributable to AI.
This is useful evidence against claims that generative AI has already caused economy-wide labour-market disruption.
But the same researchers note that broad Current Population Survey data may not have enough statistical power to identify effects concentrated in narrow groups such as recent graduates.
So the broad US null and the young-worker studies can coexist.
AGGREGATE STABILITY DOES NOT IMPLY DISTRIBUTIONAL STABILITY.
10. SKILL COMPRESSION AND SENIORITY BIAS CAN COEXIST
INTERPRETATION
One of the most interesting tensions in the evidence is this:
TASK EXPERIMENTS:
less-experienced workers often gain more from AI.
HIRING EVIDENCE:
firms may become more senior-heavy.
These are not contradictory.
A plausible mechanism is:
AI HELPS A NOVICE PERFORM A GIVEN TASK
while
A FIRM NEEDS FEWER NOVICES TO PRODUCE THE SAME TASK BUNDLE.
The first is a productivity effect conditional on being hired.
The second is a labour-demand decision about whether to hire.
Whether this mechanism becomes a durable career-ladder problem is still unknown.
11. ADOPTION IS NOT INTENSITY
FACT
Even “AI user” is not one stable treatment category.
US survey data for Q2 2026 show approximately:
• 45.2% of employed adults reporting current generative-AI use for work;
• 39.2% reporting use in the last week;
• 13.7% reporting use every workday.
These are different exposures to the technology.
They are survey-defined work-use measures; they should not be read as firm adoption rates or equal treatment intensities.
At the firm level, formal adoption and worker-led informal use can also diverge.
A worker may use a public tool even when the employer has not formally “adopted AI.”
A firm may deploy AI in a business function without most employees using it directly.
This complicates observational research.
12. WHAT ABOUT WAGES?
UNKNOWN / INTERPRETATION
Current evidence does not establish a clean causal pass-through from AI-induced productivity gains into worker wages.
This is not the same as saying that AI has no wage effects.
Examples differ:
• Denmark: no detectable incumbent earnings effect over the study horizon.
• Danmarks Nationalbank: no clear aggregate wage effect alongside slower hiring at adopters.
• BIS: workers at AI-adopting firms earn higher wages, but that does not isolate a causal productivity-to-wage transmission channel.
• UK exposure evidence can show lower posted salaries in some exposed segments while average firm pay rises because the workforce becomes more senior.
Worker capture of productivity gains remains an open question.
13. WHAT ABOUT DEMAND EXPANSION?
UNKNOWN / EMERGING
A classic complementarity argument says:
AI lowers production cost
→ prices fall or quality improves
→ demand expands
→ firms produce more
→ labour demand may recover or increase.
The early evidence is consistent with parts of this mechanism.
But foundation-model-era studies rarely observe the entire chain.
We have:
• task productivity;
• some firm productivity;
• some headcount growth;
• some labour-demand contraction.
We have much less direct evidence on:
• prices;
• output response;
• product demand;
• general-equilibrium reallocation.
So genuine demand expansion remains plausible but incompletely measured.
14. THE FOUR POSITIONS
P1 — AGGREGATE-NULL / SLOW-DIFFUSION
Claim:
Large economy-wide employment effects remain small because adoption, organisational change and reallocation take time.
Current status:
Supported with strict level and horizon qualifiers.
Strongest evidence:
• Danish incumbent earnings/hours;
• broad US monitoring;
• short-run firm-employment null in the BIS study.
This does not mean “AI has no employment effects.”
P2 — DISTRIBUTIONAL RESTRUCTURING
Claim:
Aggregate stability can coexist with major changes by age, seniority, occupation, firm and entry cohort.
Current status:
Best supported.
This is currently the strongest cross-case synthesis.
P3 — SUBSTITUTION / DISPLACEMENT
Claim:
Generative AI reduces labour demand in some tasks, firms or markets.
Current status:
Supported narrowly and unevenly.
The strongest current signal is:
• reduced hiring and entry;
• exposed UK firm/occupation contraction;
• online freelance-market displacement.
Evidence for broad incumbent layoffs is much weaker.
P4 — COMPLEMENTARITY / DEMAND EXPANSION
Claim:
AI raises productivity and can preserve or expand labour demand.
Current status:
Strongly supported at task level.
Moderately supported at firm level.
Direct evidence for the full price → demand → output → labour channel remains emerging.
15. WHAT IS OLD — AND WHAT IS NEW?
OLD TECHNOLOGICAL-CHANGE QUESTIONS
• substitution versus complementarity;
• skill-biased technological change;
• task reorganisation;
• diffusion delays;
• productivity J-curves;
• firm heterogeneity;
• entry-cohort scarring;
• labour-market reallocation.
FOUNDATION MODELS RECONFIGURE THEM
• exposure is concentrated in high-education cognitive work;
• adoption can be worker-led and informal;
• tools can improve novice task performance rapidly;
• capability frontiers change quickly;
• a single occupational exposure score can hide jagged task-level effects;
• firms can alter entry ladders before aggregate employment moves.
The combination of novice task gains and seniority-biased hiring is especially distinctive and unresolved.
16. WHAT WE STILL DO NOT KNOW
UNKNOWN
1. Will current entry-level hiring weakness persist, deepen or reverse?
2. Are the US young-worker gaps genuinely caused by AI, or partly by education composition, post-COVID trends and macro conditions?
3. Why are the broad young-worker effects near zero in Norway while US datasets show large divergences?
4. Why do two Danish register studies disagree about employment at adopting firms, and, if lower recruitment at adopters is real, will it persist as firms reorganise?
5. Will productivity gains pass through into wages, profits, prices or output?
6. Will entry-level learning ladders erode if firms hire fewer juniors?
7. What happens to displaced or downshifted entrants over five to ten years?
8. How will agentic systems change the task-to-job transmission?
9. How do collective bargaining, worker voice and labour regulation alter adoption strategies?
10. Are current results robust when actual telemetry-measured use replaces exposure indices?
17. WHAT EVIDENCE WOULD CHANGE THE PICTURE?
The current synthesis would shift materially with:
• US or UK administrative records linked to actual AI-use telemetry;
• register replications of young-worker effects in several additional countries;
• evidence that US cohort gaps disappear under stronger pre-trend and education controls;
• persistent unemployment or separations spreading from entrants to older incumbent cohorts;
• causal evidence that productivity gains raise worker wages;
• direct price/output evidence demonstrating demand expansion;
• long-run evidence of entrant career scarring or recovery;
• measured labour effects from agentic AI systems;
• a reconciliation of the two Danish studies, using one adoption measure, unit and horizon.
18. CURRENT SOCIOLENS POSITION
INTERPRETATION
The best-supported description of the 2022–2026 evidence is:
EARLY LABOUR-MARKET EFFECTS ARE DISTRIBUTIONAL BEFORE THEY ARE AGGREGATE.
Generative AI is already changing:
• task performance;
• work organisation;
• recruitment;
• entry opportunities;
• seniority composition
in some settings.
But broad employment aggregates remain comparatively stable.
The most important current tension is not:
“AI takes jobs” versus “AI creates jobs.”
It is:
LARGE TASK-LEVEL PRODUCTIVITY GAINS
COEXIST WITH
WEAKER ENTRY OPPORTUNITIES IN SOME EXPOSED LABOUR MARKETS.
The empirical question is how — and whether — those local and cohort-level changes propagate into wages, careers, firm growth and aggregate employment.

GEOGRAPHIC AND EVIDENCE SCOPE
The current evidence is strongest in:
• United States;
• Denmark;
• United Kingdom;
• Norway;
• European firm samples;
• multinational affiliates.
The corpus combines:
• randomised field experiments;
• workplace rollouts;
• administrative-register studies;
• firm panels;
• payroll data;
• business surveys;
• exposure-based event studies;
• online-platform data.
This diversity is a strength, but the designs answer different questions.
The most important geographic caution is that the US entry-level signal is not replicated uniformly across Nordic labour markets.
EVIDENCE-MATURITY CAUTION
The entry/hiring evidence is unusually 2026-heavy and working-paper-heavy. Its rapid accumulation is substantively important, but exact magnitudes and causal interpretations are more version-sensitive than the mature task-productivity evidence.
Important gaps remain in:
• Global South labour markets;
• collective bargaining and worker voice;
• long-run displaced-worker trajectories;
• SMEs and failed/abandoned adoption;
• actual-use telemetry linked to labour records;
• agentic-AI deployments;
• causal wage pass-through;
• direct price/output demand effects.
WHAT MOVED THIS DEBATE?
2023–2024
The debate was dominated by:
• task-capability forecasts;
• occupational exposure scores;
• early productivity experiments;
• speculative job-loss scenarios.
2024–2025
Workplace evidence strengthened:
• customer-support productivity;
• consulting experiments;
• platform substitution;
• early Denmark labour outcomes.
2026
The evidence base shifted decisively toward realised labour-market outcomes.
New administrative and payroll studies began measuring:
• recruitment;
• young-worker entry;
• graduate outcomes;
• firm employment growth;
• seniority composition;
• cross-country heterogeneity.
That changed the key question.
The debate is no longer only:
“Can a model perform this task?”
It is increasingly:
“Who gets hired, who stays employed, and which firms reorganise when the technology is actually adopted?”
PROVENANCE
Research build:
R05 — LD-02 — Aggregate Null or Distributional Shift? Employment — Evidence Build
Primary evidence builder:
Opus 5.5 xhigh.
The Opus build itself concluded that P1 and P2 could both hold at different margins and explicitly treated US young-worker evidence as contested rather than causal.
Final public claims were not selected by model vote.
HQ primary-source adjudication was completed in three batches:
1. Aggregate, Incumbent & Firm Nulls
2. Entry, Hiring & Distributional Restructuring
3. Task Productivity, Complementarity & Transmission
Post-Opus current-evidence update:
Danmarks Nationalbank Working Paper 223, published 16 September 2026, was independently added and adjudicated by HQ because it materially sharpened the Danish stock/flow picture.
Version 0.2:
Revised in the repository on 17 October 2026 by Claude (SocioLens Project Lead), an AI model. It cites claims LD02-HQ-C02 and LD02-HQ-C03 at v1.1 (revised 14 October 2026 after a full-text reading of Humlum and Vestergaard, March 2026) and every other claim at the version v0.1 cited. The Danmarks Nationalbank paper was not re-read.
