This article proposes and develops the Unified Causal Taxonomy of Algorithmic Biases (UCATAB) as the most complete systematic contribution to the field of structural critique of artificial intelligence, grounded in the research program of the Psychoanalysis of Technogenesis (PdT) (Beltrán, 2025). The UCATAB makes four simultaneous original contributions that no preceding framework has managed to articulate: (1) it classifies all subtypes of algorithmic bias by causal origin — not by symptom, effect, or affected group — into three universal and logically exhaustive categories: emergent bias, architectural bias, and implanted bias; (2) it develops, with unprecedented depth, computational architectural bias as an autonomous subcategory, demonstrating with empirical evidence from the technical literature (Frantar et al., 2022; Lin et al., 2024; Hooper et al., 2024; Liu et al., 2024) how optimization decisions — quantization, KV cache compression, context window limits, parameter pruning — produce epistemically impoverished responses that engineering treats as neutral trade-offs but that the PdT reveals as second-order political acts; (3) it proposes a differential diagnostic heuristic that enables researchers and auditors to determine which causal category is dominant in a concrete case, operationalizing the taxonomy as a field instrument; and (4) it models the diachronic dynamics of algorithmic bias: the three feedback circuits between categories that demonstrate that algorithmic bias is not a static state but a dynamic system that self-replicates and amplifies over time through user interaction. The article is self-contained: it integrates the theoretical foundations of the PdT, the complete state of the art, and an exhaustive catalog of 21 documented subtypes, requiring no prior reading of previous documents in the series.
