Contribution to the handbook
Supporting · Assessed 2026-10-27
The records describe structured experiments involving 5,734 UK participants, including a virtual citizens’ assembly, and identify limits in the supplied participant and recruitment detail. This provides evidence context for the handbook’s testing discussion, but sample size is not evidence of effectiveness or representativeness beyond the reported design.
Does this challenge the goal?
In-scope gap
The question establishes the scale and setting of relevant evaluation evidence, a useful scope consideration for testing; it does not challenge the definition’s goal.
Participant count and recruitment details alone do not demonstrate effectiveness or broad transferability.
Why this category?
- Establishes the study’s overall participant scope and UK setting
- Distinguishes study scale from evidence of effectiveness
- Provides context rather than a system specification or tested governance recommendation
The supplied records do not give a full breakdown across experiments or all demographic results, and all derive from the same article.
This is an AI assessment of contribution to the goal, separate from whether the question has an answer.

Describe the study design and its overall participant scope without treating sample size as evidence of effectiveness.
What we can say so far
The researchers report conducting structured experiments with 5,734 human participants in total, in UK settings. The study included training and evaluation groups and a virtual citizens’ assembly; the researchers also collected additional cohorts to test parts of the system and whether findings carried over to new topics. The supplied passages report 2,473 training and 2,673 evaluation participants, but do not reconcile those figures with the reported total. These participant counts describe the study’s scope, not evidence of effectiveness.
What remains open
- The supplied passages do not provide a full breakdown of participants across experiments or reconcile the 5,734 total with the 2,473 training and 2,673 evaluation figures.
- The additional cohorts are mentioned without their participant counts.
Conditions and limits
- The participant total and study details are reported from the supplied readable article text; supplementary materials are not included.
- The count describes study scope and does not establish effectiveness or generalizability.
Objections to consider
- The reported training and evaluation counts sum to 5,146, while another supplied passage reports 5,734 participants overall. The passages do not explain the difference; additional cohorts are mentioned but not quantified.
