The Scientific Foundation

Not a promise. Validated architecture.

The difference between an agent that impresses in a demo and one that survives an audit begins with the science that sustains it. More than a decade of behavioral research anchors every Legathum decision.

TL;DR

The science, in four facts.

Multidimensional Neuro-Cognitive-Behavioral Theory, the basis of the VCEA architecture
The theory

TNCM and VCEA: how a mind decides.

TNCM — the Multidimensional Neuro-Cognitive-Behavioral Theory — is the theoretical body that sustains Legathum. From it derives VCEA, the proprietary behavioral architecture that maps decision judgment across four dimensions with neuroanatomical anchoring.

The difference from a conventional personality test is structural: VCEA does not classify the person into a box, it maps how the person decides — the patterns under uncertainty, the non-negotiable values, the risk thresholds. It is that map that trains each agent.

Prefrontal

Visionary

Strategy, long-term vision, decision under uncertainty.

Hemispheric

Creative

Generation of alternatives, non-obvious association, innovation.

Limbic

Empathetic

Reading people, culture, transmission of values.

Cortical

Analytical

Rigor, data, validation, risk management.

The validation

What is validated, demonstrated and under research.

VALIDATED

98.8% accuracy

The behavioral architecture was independently validated at 98.8% accuracy, per UFC Report 02-2/2017, over a sample of 259 subjects (N=259).

DEMONSTRATED

2023 public case

In October 2023, in São Paulo, the world's first public cognitive digital twin was demonstrated operating with the cognitive signature of its original. Pioneer credit of the technical thesis.

FOUNDATION

Dataset & MemorAI

Proprietary psychometric dataset of 5M+ profiles, structured and consented (never scraping). The MemorAI infrastructure originates in academic research by alumni researchers of the UC Berkeley iSchool.

Compliance & data

Science with governance, by design.

Data capture is structured and consented, in full compliance with the GDPR. Every agent operates with human oversight at critical points and an auditable decision trail — compliant with Regulation EU 2024/1689 (EU AI Act).

The 98.8% metric refers to the iPersonality architecture validated per UFC Report 02-2/2017 (N=259). The MemorAI technical infrastructure originates in academic research by alumni researchers of the UC Berkeley iSchool — an academic citation, with no institutional affiliation or endorsement. The 2023 public case corresponds to a demonstration of the technical thesis; subsequent transactions between third parties are independent agreements. Legathum hybridizes processes and does not practice medicine.
