Canonical Definition
The Legalome is the application of microbiome sciences and objective omics-derived markers in forensic and legal psychology.
The Legalome concerns the explanatory and practical relevance of microbes, microbe-derived metabolites, and objective omics-derived markers in cognition, behavior, legal psychology, and justice involvement. It includes the ways in which the human microbiome acts as a biological transducer of environmental inputs that may intersect with brain architecture, function, and behavior.
The Legalome also includes intersections with other omics-derived markers, including genomics, metabolomics, epigenomics, transcriptomics, and related biological measures that may help bring objectivity to domains traditionally dominated by paper-and-pencil self-report, narrow behavioral interpretation, and subjective clinical impressions.
Summary: The Legalome is the biological ecology of justice.
What the Legalome Is Not
The Legalome is distinct from forms of forensic microbiology primarily concerned with:
- human identification
- placing a perpetrator at a crime scene
- establishing postmortem intervals
- determining cause of death
Instead, the Legalome focuses on the explanatory and practical relevance of microbiome science, microbe-derived metabolites, and objective omics-derived markers in the context of cognition, behavior, legal psychology, and justice involvement.
Scope of Application
The Legalome includes applications within forensic psychology, but it is not limited to forensic psychology.
It is also situated within the broader field of legal psychology, including all actors within systems of criminal justice, encompassing the behavior, lifestyle, occupational conditions, and fitness-for-duty of law enforcement personnel, judges, lawyers, corrections professionals, and forensic practitioners.
This broader scope matters because legal and justice systems are high-stakes, high-stress environments in which biological ecology, environmental inputs, burnout, cognition, judgment, and performance may intersect in consequential ways.
Why It Matters
The Legalome introduces an ecological and biologically informed framework into legal and forensic psychology.
It expands inquiry beyond isolated behavioral interpretation by incorporating microbiome science and objective omics-derived markers into questions of context, vulnerability, behavior, legal responsibility, mitigation, justice involvement, and institutional performance.
As microbiome science, neuromicrobiology, and omics continue to evolve, the Legalome offers a framework for thinking more carefully and more objectively about the biological ecology of justice.
