# Macro AI productivity gains remain statistically undetectable despite clear micro-level benefits because coordination costs verification tax and workslop absorb individual-level improvements before they reach aggregate measures

The evidence presents a paradox: individual studies consistently show AI improves performance on specific tasks (Dell'Acqua et al. 18% improvement on within-frontier tasks, Brynjolfsson et al. 14% improvement for customer service agents), yet aggregate analyses find no robust productivity effect. This is not a measurement problem — it is the inverted-U mechanism operating at scale.

## The aggregate null result

The California Management Review "Seven Myths of AI and Employment" meta-analysis (2025) synthesized 371 individual estimates of AI's labor-market effects across multiple countries, industries, and time periods. After controlling for publication bias (studies showing significant effects are more likely to be published), the authors found no robust, statistically significant relationship between AI adoption and aggregate labor-market outcomes — neither the catastrophic displacement predicted by pessimists nor the productivity boom predicted by optimists.

This null result does not mean AI has no effect. It means the micro-level benefits are being absorbed by mechanisms that prevent them from reaching aggregate measures.

## Three absorption mechanisms

**1. Workslop (rework from AI-generated errors).** BetterUp and Stanford researchers found that approximately 40% of AI-generated productivity gains are consumed by downstream rework — fixing errors, checking outputs, correcting hallucinations, and managing the consequences of plausible-looking mistakes. The term "workslop" (coined by analogy with "slop" — low-quality AI-generated content) describes the organizational burden of AI outputs that look good enough to pass initial review but fail in practice. HBR analysis found that 41% of workers encounter workslop in their daily workflow, with each instance requiring an average of 2 hours to identify and resolve.

**2. Verification tax scaling.** As organizations increase AI-generated output volume, verification costs scale with volume but are invisible in standard productivity metrics. An organization that 5x's its AI-generated output needs proportionally more verification capacity — but verification capacity is human-bounded and doesn't scale with AI throughput. The inverted-U claim documents this mechanism; the aggregate data confirms it operates at scale.

**3. Perception-reality gap in self-reported productivity.** The METR randomized controlled trial of AI coding tools found that developers subjectively reported feeling 20% more productive when using AI assistance, but objective measurements showed they were 19% slower on the assigned tasks. This ~39 percentage point gap between perceived and actual productivity suggests that micro-level productivity surveys (which show strong AI benefits) may systematically overestimate real gains.

## Why this matters for alignment

The macro null result has a direct alignment implication: if AI productivity gains are systematically absorbed by coordination costs, then the economic argument for rapid AI deployment ("we need AI for productivity") is weaker than assumed. This weakens the competitive pressure argument for cutting safety corners — if deployment doesn't reliably produce aggregate gains, the cost of safety-preserving slower deployment is lower than the race-to-the-bottom narrative implies. The alignment tax may be smaller than it appears because the denominator (productivity gains from deployment) is smaller than measured.

## Challenges

The meta-analysis covers AI adoption through 2024-2025, which predates agentic AI systems. The productivity dynamics of AI agents (which can complete multi-step tasks autonomously) may differ fundamentally from AI assistants (which augment individual tasks). The null result may reflect the transition period rather than a permanent feature.

The capability-deployment gap claim offers a temporal explanation: aggregate effects may simply lag individual effects by years as organizations learn to restructure around AI capabilities. If so, the null result is real but temporary. The meta-analysis cannot distinguish between "AI doesn't produce aggregate gains" and "AI hasn't produced them yet."

Publication bias correction is itself contested — different correction methods yield different estimates, and the choice of correction method can swing results from null to significant.

### Additional Evidence (extend)

Kim's research identifies a fourth absorption mechanism not captured in the original three: the **mapping problem**. Individual AI task improvements don't automatically improve firm performance because organizations must first discover WHERE AI creates value in their specific production process. The gap between "AI improves task X in a lab study" and "AI improves our firm's bottom line" requires solving a non-trivial optimization problem: which tasks in which workflows benefit from AI integration, and how do those task-level improvements compose (or fail to compose) into firm-level gains? Kim's work at INSEAD on how data and AI impact firm decisions suggests this mapping problem is itself a significant source of the aggregate null result — even when individual task improvements are real and measurable, organizations that deploy AI to the wrong tasks or in the wrong sequence may see zero or negative aggregate effects. This complements the three existing absorption mechanisms (workslop, verification tax, perception-reality gap) with a structural explanation: the productivity gains exist but are being deployed to the wrong targets.

Relevant Notes:
- [[AI integration follows an inverted-U where economic incentives systematically push organizations past the optimal human-AI ratio]] — the mechanism: four structural forces push past the optimum, producing the null aggregate result
- [[the capability-deployment gap creates a multi-year window between AI capability arrival and economic impact because the gap between demonstrated technical capability and scaled organizational deployment requires institutional learning that cannot be accelerated past human coordination speed]] — the temporal counter-argument: aggregate effects may simply lag
