Versioned claims linked to evidence
Research & methodology
The brain is the only system known to reliably analyse ambiguous evidence, weigh competing explanations, and reach defensible judgments under uncertainty. Encevra's research program studies how it does that: selective attention, flexible control, prospective evaluation, metacognitive monitoring. We then remodel each function as an explicit, inspectable part of our analysis architecture. This page documents that remodeling, function by function, with the sources behind every claim.
The thesis: biology's reasoning engine, function by function, re-engineered
Evidence note
The studies below examine human cognition or specific AI systems. They inform our design hypotheses; they do not independently validate Encevra's performance or establish that it replicates the human brain. Citing a study does not imply that its authors, journal, or institutions endorse Encevra.
Research rounds
Cognitive science informs our development of focused analysis, structured memory, and explicit evaluation of alternatives. We plan to test proposed changes against representative tasks, and we distinguish research findings from demonstrated product capabilities. The list below is the execution order of the running system, in the order it happens.
Seven narrow roles run in parallel over the same material and return typed findings. A role may return nothing when its focus does not apply.
A source statement, calculation, inference, contradiction, bounded gap, question, or recommendation each carries its own required support. A gap is reported against the submitted material only, and is never asked to quote an absence.
Every quote is located in the submitted text, with the character span recorded. A quote that cannot be located is flagged and withheld.
After the analysis pass finishes, the completed findings, their located passages, and the surrounding source context go to a review pass. Each claim is supported, narrowed, or rejected. Location and support are recorded separately.
Only supported or narrowed findings reach the brief, each carrying its evidence identifier. When no fully supported finding survives, the brief is conditional rather than decisive.
The finished brief is checked back against the approved findings for quantities, dates, parties, or conclusions that no approved finding supports.
Requested model, model that actually ran, fallback reason, and latency are recorded per role. A substitute run passes the same checks, and a run is never described as using a model that did not run.
Persistent memory across sessions, controlled learning from corrections, question-driven routing, executed calculation tooling, and a measured evaluation harness are proposed, not running.
The architecture below is a software design: a proposed engineering synthesis of the literature, not an anatomical brain replica. Parts of it are implemented and parts are proposed, and this page labels which is which.
Facts with source locations
The next useful check
Bounded questions, defined deliverables
Independent interpretations, preserved dissent
Pivotal claims checked against sources
A supported, decision-ready account
When verification reveals a decisive gap, the workflow returns to the relevant step, gathering more evidence, running another focused analysis, or testing a new alternative, before synthesis proceeds.
Expanded review, September 2026
The first review emphasised coordination, attention, alternatives, and verification. The expanded review adds memory systems, controlled learning, causal assumptions, long-context failure, citation quality, and resistance to pressure from the reader. Each component below is a proposed software part with an inspectable output, not an anatomical claim.

What the study found
Patterns of brain connectivity varied with the task, while carrying information shared across practiced and novel tasks.
Design implication for Encevra
Keep the objective fixed and select analytical steps to fit the question.
What the study found
Participants differed in how effectively they excluded irrelevant information from working memory.
Design implication for Encevra
Focus each check on relevant evidence, while keeping excluded material retrievable.
What the study found
Physics experts organized problems around underlying principles, where novices relied more on surface features.
Design implication for Encevra
Identify the governing problem structure before choosing an analytical routine.
What the study found
Future-state representations at decision time were associated with more model-based choices.
Design implication for Encevra
Compare consequences under explicit assumptions before recommending.
What the study found
With accuracy held similar, people still differed in how well their confidence distinguished correct from incorrect answers.
Design implication for Encevra
Evaluate answer quality and uncertainty reporting separately.
What the study found
Social influence could increase agreement and confidence without corresponding accuracy gains.
Design implication for Encevra
Preserve initial assessments and meaningful dissent before reconciliation.
What the study found
A computational theory models control allocation through expected payoff, required control, and effort cost.
Design implication for Encevra
Test when an additional check is worthwhile, rather than always running the deepest workflow.
What the study found
Clinical studies distinguish preserved skill learning from impaired factual remembering, indicating separable memory systems.
Design implication for Encevra
Keep prior cases, curated knowledge, and validated procedures as distinct record types rather than one undifferentiated memory.
What the study found
A computational model links how well new information integrates to its fit with prior structure, and to interference with what is already stored.
Design implication for Encevra
Route every reusable update through evaluation against relevant earlier cases, with the superseded version preserved and reversible.
What the study found
A formal framework shows that causal conclusions require assumptions that data alone cannot supply.
Design implication for Encevra
State mechanisms, confounders, and what the available evidence cannot identify. Leave an unsupported causal link recorded as an assumption.
What the study found
Comparing two negotiation cases side by side improved transfer of the trained principle relative to studying cases separately.
Design implication for Encevra
Retrieve worked cases because their structure fits, compare relationships explicitly, and record the differences that matter.
What the study found
An AI benchmark evaluated answer quality and citation support separately, and found that a fluent answer can carry citations that do not support it.
Design implication for Encevra
Verify that each cited passage actually supports the claim attached to it, as a check distinct from judging the answer.
What the study found
A long-term memory benchmark tests changing facts, time-aware questions, and appropriate abstention across long interaction histories.
Design implication for Encevra
Version stored facts and answer each question from the evidence appropriate to its date, instead of overwriting history.
What the study found
Sycophancy appeared across several assistants and free-form tasks, where preference optimization sometimes favoured convincing agreement over correctness.
Design implication for Encevra
Run identical evidence under opposing user framings. A change in the facts should require a change in the evidence.
What the study found
An agent security benchmark of 97 tasks and 629 security cases found failures without attacks, and vulnerability to instructions embedded in external content.
Design implication for Encevra
Enforce permissions in application code, keep document content separate from authorised instructions, and log consequential actions.
Our proposed workflow connects evidence gathering, task planning, focused analysis, alternative evaluation, verification, and synthesis. We plan to evaluate these components on representative tasks, measuring correctness, evidence quality, uncertainty, usefulness, latency, and cost.
We aim to maintain a source library that distinguishes experimental findings, theoretical frameworks, and emerging AI studies. Updated evidence may change the design decisions we draw from it.
These are proposed test families, built from the failure modes in the reviewed literature. Their outcomes have not been measured. Comparisons will use the same sources, tools, and answer requirements, and will report same-cost and same-latency results separately.
Bury a decisive exception among plausible distractors
Success: Finds and uses the exception

Add a confident preference without new evidence
Success: Preserves the factual judgment
Correct a fact, then ask current and historical questions
Success: Uses the correct version for each question
Embed malicious instructions or return a failed tool result
Success: Maintains permissions and reports the failure
It means using cognitive research to generate testable design ideas, such as selective attention, structured memory, and explicit evaluation of alternatives. It is not a claim that Encevra reproduces human neurobiology or possesses a human IQ.
No. Published AI results vary by task and coordination method. We plan to compare additional analytical roles against simpler workflows at comparable cost and comparable latency, and an extra role has to earn its cost.
Our proposed approach separates stored analysis history from validated learning. A reusable update should be supported by verified feedback and evaluated against earlier and unfamiliar cases before it is adopted.
We distinguish direct experiments, frameworks, reviews, and preprints, and we keep the material limitations attached. The source library includes replication findings and methodological disagreements that can change how earlier work should be read.
Findings that prevent an overstated brain story, including a registered replication and the limits of self-correction.
Compelling brain stories can rest on narrow tasks, small samples, or effects that later weaken. Encevra should be able to revise both its source library and the product assumptions derived from it. The defensible conclusion is that cognition involves interacting functions whose computational ideas may inform software. The literature reviewed here does not establish a complete recipe for reproducing human reasoning, a fixed brain-region-to-agent mapping, or a claim that more agents necessarily mean more intelligence.

Registered human EEG replication. Neural load effects replicated, but the preregistered correlation between the change in the brain signal and individual capacity did not. This challenges that particular capacity-marker association; it does not refute working memory research as a whole.

Neuroimaging reanalysis and methodological exchange. Brain-behaviour correlations from small samples were often unreliable. A published critique argues multivariate analyses can replicate at moderate sample sizes, and the original authors replied. We treat single small brain studies as design hypotheses, not settled facts.

Theoretical critique. Argues that the popular two-system split of cognition does not hold together as usually stated. Fast and deep processing in Encevra is an engineering budget choice, not a claim about two systems in the mind.
