Personality transposition – the transfer or reconstruction of human personality traits and identity patterns into new biological or artificial substrates – is investigated through an interdisciplinary lens. We integrate ancient philosophical notions of the self and vibration with modern advances in neural engineering, artificial intelligence (AI), microbiome research, and quantum technology. A knowledge gap is identified at the nexus of metaphysical continuity of self and practical cognitive overlays deployable in real-world systems.

We propose a multi-modal model combining biological affect modulators (e.g. neural prosthetics, microbiota-based mood tuning) with computational identity simulacra (AI trait embeddings, preference-based policy cloning, voice/style transfer). Materials and Methods detail conceptual modeling and a novel continuity scoring to evaluate fidelity of transposed personas. Results describe an operational taxonomy of transposition approaches across substrates, illustrated by an affect-modulation kit, decision-policy vector transfer, and voice-styled AI operator overlays. A table of substrate compatibility clarifies which personality facets can migrate to which targets.

Discussion addresses identity authenticity (drawing on Parfit’s and Locke’s theories of continuity vs. immutability of self), ethical and security risks (covert persona simulation, memory misattribution), strategic applications (cloning decision-making styles for resilience or deception), and legal constraints (EU AI Act transparency requirements, biometric and publicity rights). This comprehensive study – framed in the Invictus Cymatech philosophy of blending ancient insight with cutting-edge tech – lays groundwork for a rigorous continuity-centric framework for personality transposition.
