School of thought
Human augmentation and sociotechnical systems
Matched on representative researcher.
Intelligence and value reside in the joint human-machine-organization system, not the automation alone.
Critique. Human behavior and institutions are context-dependent; laboratory usability may not predict long-run value or harm.
Modern descendants. Copilots, agent supervision, workflow redesign, adoption metrics, and human-centered AI.
Understand
Plain-language record, transferred from the reviewed source module.
Theory or experimental setup. Created a cheap, repeatable instrument that helped normalize empirical usability assessment.
Result / historical claim. A coarse subjective measure cannot diagnose causes, predict safety, or replace task-performance data.
Apply
Professional implication, only where the reviewed record states one.
The checked-in record does not state a separate professional application for this entry. The topic page places it in the wider research lineage: Reliability, uncertainty, and evaluation.
Verify
Evidence status, stated limitations, and the external sources this record actually carries.
Evidence form. Ten-item post-use questionnaire designed as a quick, technology-independent usability measure
Limitation / debate. Standardized user evaluation for copilots and agents alongside objective success, error, and trust measures.
Source status. The source link below is the verified link our reviewed topic research already carries for this milestone.
Reproduce
A reproduction tutorial is linked only when one exists for this exact record.
A reproduction tutorial is not yet available for this entry. The closest reviewed material is Reliability, uncertainty, and evaluation.
Cite or share
APA-like: This historical record carries a year only, and no author or publisher of record in the checked-in data. An APA reference would have to invent that metadata.
BibTeX: BibTeX requires an author and publication venue. Historical lineage entries store a narrative record and its source link, not structured authorship, so the field would be fabricated.
