Embodied Biographical Alignment (EBA) v0.2.3: Plural Biography as a Determinant of Future Learning

Abstract

Embodied Biographical Alignment (EBA) proposes that some alignment-relevant consequences of learning may depend on temporally extended, causally structured developmental histories rather than on descriptions or terminal outputs alone. EBA v0.2.1 introduced biography as a temporally connected sequence in which earlier actions alter later options and consequences, together with a requirement that integration be transformative rather than merely archival. EBA v0.2.2 then framed developmental equivalence as an operational question: if systems are similar at a comparison point, will they learn, adapt, and generalize similarly after the same subsequent experience? This note extends that question from one history to multiple histories. Its central proposal is that plural developmental history should be tested as a possible determinant of future learning. The note distinguishes multiplicity, diversity, and biography; formulates four falsifiable hypotheses; maps competing explanations including joint training, multi-teacher distillation, model merging, dynamic routing, retrieval, multiplicity, and diversity; and specifies a minimal simulated environment with matched future experience. A positive result would support only a limited claim: that multiple causally structured developmental histories can leave a reproducible and causally identifiable effect on the subsequent learning dynamics of a unified system that is not fully reproduced by simpler matched alternatives. This note operationalizes only one component of the broader EBA proposal; reproducing this endpoint with a simpler mechanism would not establish equivalence to EBA as a whole. The proposal makes no claim about machine consciousness, subjective experience, wisdom, or automatic moral improvement.
