Abstract: The persistent confusion between graphology (psychological profiling) and forensic handwriting examination constitutes a problem of evidentiary rationality and expert knowledge governance in Hispanic legal systems. Through a critical integrative review with a multidisciplinary approach, this study demarcates both practices epistemologically, demonstrating that graphology operates as a non-falsifiable projective system with null predictive validity (r ≈ .15), whereas forensic handwriting examination, though imperfect, is empirically controllable (error rates ~3.1%) and methodologically transparent. Jurisprudential analysis reveals ambiguous judicial reception in Mexico and Spain, where terminological synonymy hinders specific epistemological filters. It is concluded that rigorous conceptual delimitation, mandatory use of standardized terminology, and implementation of Daubert-type mechanisms constitute ethical-legal requirements to safeguard documentary evidence integrity and reduce cognitive biases in judicial valuation.
