The epistemology of death: psychological autopsy, artificial intelligence, and forensic decision

Psychological autopsy occupies a unique position within forensic science, operating at the intersection of empirical observation and interpretive reconstruction. Unlike traditional forensic methods that rely primarily on physical evidence, psychological autopsy seeks to reconstruct the internal mental state of a deceased individual—an inherently unobservable phenomenon.

This study demonstrates that its primary value does not lie in producing definitive conclusions but rather in structuring uncertainty in a systematic and methodologically transparent manner. In equivocal death investigations, this structured uncertainty becomes particularly significant, as legal systems often require probabilistic reasoning in the absence of direct evidence. Psychological autopsy therefore functions as an epistemic bridge between behavioral science and legal decision-making.

The integration of artificial intelligence and digital data represents a substantial methodological transformation. Digital footprints provide unprecedented insight into behavioral trajectories; however, this expansion of data does not eliminate interpretive ambiguity. Instead, it redistributes uncertainty into algorithmic systems, where bias may be embedded in data selection, labeling practices, and model architecture. As noted in the forensic psychiatry literature, computational inference cannot replace clinical judgment but may serve as a complementary analytic layer (Buda et al., 2020). In this respect, artificial intelligence simultaneously complements and challenges traditional psychological autopsy. It complements conventional approaches by expanding access to longitudinal behavioral data and pattern recognition capabilities, yet it challenges them by introducing new forms of opacity, uncertainty, and dependence on computational assumptions.

From an ethical perspective, psychological autopsy raises fundamental questions regarding post-mortem privacy and digital identity. The reconstruction of psychological states through digital records challenges traditional legal and moral boundaries surrounding informational autonomy after death. This concern becomes more pronounced in contexts where legal frameworks do not clearly define the status of digital remains. Consequently, ethical governance must extend beyond consent-based models toward post-mortem data stewardship frameworks (Edwards and Harbinja, 2013).

Within the Turkish legal system, the method is partially recognized but not formally regulated. Judicial practice indicates an increasing reliance on psychological interpretation in equivocal death cases, particularly through expert reports and indirect behavioral evidence.

However, the absence of standardized procedural guidelines leads to variability in forensic practice and evidentiary evaluation, thereby reducing reproducibility and potentially affecting judicial certainty (Yargıtay 12th Criminal Chamber, 2015).

From an epistemological perspective, psychological autopsy reflects the broader limitations of forensic science in addressing mental phenomena. As emphasized in classical sociological and suicidological literature, human behavior cannot be fully reduced to observable physical traces (Durkheim, 1897; Hawton and Appleby, 1988). Instead, its interpretation requires frameworks that integrate social, psychological, and contextual dimensions. This position situates psychological autopsy within a probabilistic rather than a deterministic scientific paradigm.

The future development of the field may depend on three interconnected dimensions. First, methodological standardization is required to reduce variability in data collection and interpretation. Second, interdisciplinary integration—particularly among forensic psychology, data science, and law—must be strengthened to ensure analytical coherence. Third, ethical and legal regulation must evolve in parallel with technological capabilities, particularly with respect to digital evidence and post-mortem data rights.

Ultimately, psychological autopsy should be understood not as a standalone diagnostic tool but as part of a broader evidentiary ecosystem. Its strength lies not in certainty but in its ability to organize fragmented and indirect information into a coherent interpretive structure. In this sense, it reflects not only the ambiguity of death itself but also the epistemological limits of forensic certainty in the analysis of complex human phenomena.

This study contributes to the literature by reframing psychological autopsy as a hybrid epistemic system operating at the intersection of forensic inference and computational augmentation.
