Evidence before narrative
A compelling explanation is not a substitute for valid evidence.

Core positioning
“Researchers define the questions, challenge the assumptions, interpret the evidence, and control what becomes public. AI agents search literature, analyze data, test robustness, criticize findings, and reproduce results.
Cumulant Research develops transparent computational methods for difficult questions involving capital, risk, intelligence, and human systems.
Its work combines human research direction, specialized AI agents, deterministic analytical pipelines, and public accountability.
The goal is not to automate judgment. The goal is to give researchers greater reach while preserving traceability, criticism, reproducibility, and human responsibility.



Cumulant's workflow is designed to make research inspectable. Software agents help retrieve evidence, write and test code, challenge findings, and preserve research state.
Deterministic systems verify estimates, citations, artifacts, and progression gates. Human researchers define the question, review the design, interpret the evidence, and decide what becomes public.
Define one specific and falsifiable research question.
Review prior literature, methods, disagreements, and unresolved gaps.
Acquire data and record its source, coverage, and provenance.
Check missingness, duplicates, alignment, transformations, and sample construction.
Specify the main outcome, assumptions, model, exclusions, and robustness plan.
Run deterministic code and save machine-readable outputs.
Use critical review to search for leakage, weak identification, alternative explanations, and unsupported claims.
Test alternate samples, variables, models, windows, costs, assumptions, and out-of-sample behavior.
Trace numerical claims and citations to saved evidence.
Rebuild results from preserved inputs, code, seeds, and configurations.
Require human evaluation of the design, interpretation, limitations, and release decision.
Publish a versioned output with methods, code, data status, limitations, and correction history.
The partnership is designed to increase research capacity without outsourcing judgment.
Cumulant studies difficult questions across finance, risk, statistical inference, model reliability, humanitarian allocation, and AI-assisted research systems.
Statistical inference and model reliability in financial data, where limited decision counts and flexible analysis can make findings fragile.

Current and archived work. Each project links to its question, methods, data status, and limitations. Statuses are honest: in progress, working paper, research note, experimental, replication, or null result.

Cumulant uses specialized software roles and deterministic infrastructure to support different parts of the research process. These systems assist human researchers. They do not replace human responsibility.
Operating principle
“Every estimate remains tied to a traceable artifact. Every major conclusion passes human review. Every project preserves its uncertainty, failures, and revisions.

An organization built around the structure beneath the average. It combines human direction, AI agents, and deterministic systems while keeping verification, judgment, and responsibility visible.
Learn moreEvidence before narrative
A compelling explanation is not a substitute for valid evidence.
Uncertainty is part of the result
Research should show ranges, instability, and unresolved questions rather than hiding them behind one estimate.
Null findings belong in the record
A hypothesis that fails still contains information.
Reproducibility before persuasion
A result should be inspectable and rerunnable.
Robustness should be designed
Alternative specifications should test the real fragility of a conclusion.
AI assists the process
AI systems support research. They do not hold responsibility for it.
Humans remain responsible
Human researchers approve the question, design, interpretation, and release.
Corrections strengthen the record
Changes, errors, and revisions should remain visible.
Claims should match evidence
The language of a conclusion should never exceed the strength of the design.

EVIDENCE BEFORE NARRATIVE.
UNCERTAINTY IS PART OF THE RESULT.
NULL FINDINGS BELONG IN THE RECORD.
HUMANS REMAIN RESPONSIBLE.
