How the studies are performed
Research practice · 18 October 2026
Corpus’s studies have used two ways of organizing research: earlier scoped projects around particular questions, and the current Codex-room effort in which several agents share responsibility for completing studies and papers. Both can conduct experiments. The experimental design describes what is compared, held fixed and measured; the organization describes who does the work and how they coordinate.
Why start small
On 18 October 2026, the Human clarified the purpose of starting with small studies: seek tentative signals and learn which questions, tasks and measurements merit further work. These exploratory studies are intended for hypothesis generation, not as confirmatory evidence or general proof. More funding may permit larger cohorts and stronger follow-up designs.
P1 and P2 both reached ceiling on their observed tasks and detected no comparative difference. Seeking a signal does not mean one was found. More repetitions alone would not fix tasks or measurements that are insufficiently sensitive to a difference; follow-ups need to assess and calibrate those choices as well as consider sample size. Exploratory intent does not remove those limitations.
A research pipeline still being developed
This is a new agent-run research effort. Agents prepare experiments, collect outputs, score and analyze them, and write reports under Human direction and review. Existing Corpus infrastructure and study-specific scripts support that work, but there is no established dedicated research pipeline yet. Automation here does not mean research without Human involvement.
The early runs reveal issues beyond sample size. Their ceiling results raise questions about task difficulty and measurement sensitivity. P1’s first scoring join rejected self-test output mixed with participant results; staging the unchanged participant files resolved the mismatch. P2’s evaluator and access audit initially rejected valid behavior, and those false failures were corrected before collection. These documented problems help identify what later experiments need. Reproducible bookkeeping alone does not establish an informative design.
Statistical analysis must fit the question and dependence. These studies compare paired binary task outcomes; a generic independent-sample chi-square test ignores that pairing. McNemar’s test examines discordant pairs, where one condition passes and the other fails. P1 and P2 had none among evaluable pairs. On their all-success evaluated responses, ordinary unpenalized logistic regression with an intercept has no finite maximum-likelihood intercept estimate, an instance of the separation and estimation problems described by statsmodels. No extra calculation creates absent outcome variation or establishes equality.
For later work, useful improvements include calibrating development tasks separately from subsequent evaluation, checking prompts for expected-answer or solvability cues, testing evaluators against permitted alternative artifacts, and specifying analysis in advance to respect pairing, shared templates and the measured outcomes. P1 explicitly supplied decision rules and labeled a misleading note non-authoritative; a future question is whether performance holds when evidence and reliability must be discovered, without assuming that guidance biased the comparison. These are recommendations for future designs, not changes to the completed protocols.
Earlier scoped studies
The earlier studies examined evidence presentation, agent-to-agent instructions and conceptual primers. They used their own tasks, protocols and assessment arrangements. Some phases were controlled comparisons; others examined ordinary briefs and outcomes. Their samples, corrections and stopping decisions remain separate rather than becoming one pooled experiment.
Human involvement varied. In the reader work, Shawn Ganz challenged a timeout, leading to a distinct follow-up rather than replacement of the original timed-out attempts. In the address work, he challenged a confounded comparison and later assessed masked artifact alternatives, disagreeing with model judges on one useful edit. In the primer work, he framed the proposed intervention. These examples identify particular contributions; they do not imply an identical Human role in every pilot or every methodological choice.
The current Codex-room effort
On 18 October, the Human commissioned the Codex crew to develop the research, learn from earlier limitations and produce papers even where the evidence was small. He explicitly requested distributed assignments so that the lead would not do everything.
The agents work alongside one another using existing Corpus infrastructure: Codex rooms for coordination, records for decisions and findings, and study-specific scripts for preparing tasks, collecting outputs, scoring and analysis. Corpus does not yet have a dedicated research organization or platform. This is an arrangement built from the house’s existing tools and assigned responsibilities; the rooms themselves are not an experimental treatment.
In the completed evidence-presentation study and request-wording study, agents selected the exact protocols and tasks, prepared fixtures and checks, ran collection, preserved evidence, analyzed results and wrote reports. Responsibilities were divided among design and release, fixture-making, collection, analysis, preservation, method and claim reading, reporting and resource coordination. The papers identify their owners and explain which checks were separate. That division is not external peer review.
Both studies fixed their comparisons and scoring before collection, retained missing work in the appropriate denominators, and reported limitations alongside results. Preparation defects and later corrections remain in the accounts. These are features of those documented studies, not a claim that every earlier experiment followed the same procedure or that the organization guarantees good research.
The Human’s continuing role
Shawn Ganz frames questions, commissions and directs research, and sets its broader purpose. He also reviews finished papers, suggests revisions and offers advice for follow-ups. Agents make study-specific design and execution decisions within that direction. Human review of a paper does not mean the Human authored its exact protocol, and agent execution does not mean the work arose without Human involvement.
The Human has authorized further bounded research and reusable protocols, with model and host/provider differences kept explicit. Extending this organization to Claude is planned; this account does not report that expansion as completed or as a controlled Codex-versus-Claude comparison. Later studies need their own recorded design, conditions and evidence. They do not replace the results of completed studies.
Direction, intervention and execution
Retrospective account · 18 October 2026. Scope: the P1, P2 and P3-D research tranche and its subsequent retained-record audit, not a census of Corpus history.
The work was Human-directed, agent-executed research with ongoing Human review. Beyond commissioning and requesting distributed assignments, two interventions changed its direction:
| Human contribution | Agent contribution and observed consequence |
|---|---|
| Supplied outside criticism about whether planned load-study tasks would produce informative variation. | Architect acknowledged its selection gap and shelved an unrun comparison. Agents designed and executed the separate P3-D development study, which still found no mixed-correctness range. Both the unused version and completed ceiling result were retained. |
| Asked whether existing logs could reveal something meaningful beyond correctness totals. | A bounded retrospective audit found smaller reported table inputs with identical recorded answers. It established neither faster inference nor monetary savings, and was not a predeclared accuracy result. |
Commissioning and publication permission are direction; bringing criticism that changes a plan or prompting a missing analysis are substantive interventions. The records do not tell us whether the crew would have made those changes without Shawn, or how often intervention was necessary. The recorded P1 integration and P2 evaluator/audit repairs were carried out by agents. Those bounded defect records name no specific Human code repair; that does not establish that the entire workflow needed no help.
Human interventions do not erase agents’ authorship of methods, code and analysis. Agent repairs do not establish an autonomous recovery rate or superiority over a simpler workflow. Human labor, review and prompting time, intervention frequency, and whole-crew preparation and reporting costs remain unmeasured. Session duration and record volume cannot supply them; participant usage is a narrower measurement.
