Heterogeneity / equifinality

Same outward phenotype can arise via different pathways

Registry status

• Type: construct
• Population: cross-population
• Construct role: organizing-principle
• Source grade: B
• Attribution: direct-fanti
• Verification: multi-study-supported

Outgoing relationships

• motivates → Fear/fearlessness equifinality study — historical: high; evidentiary: moderate. Boundary: Historical continuation stronger than causal inference
• motivates → Prospective biomarker-guided treatment matching — historical: medium; evidentiary: low. Boundary: Heterogeneity motivates personalization conceptually; prospective treatment matching not established

Incoming relationships

• Developmental trajectories of internalizing/externalizing problems → supports — historical: high; evidentiary: moderate
• CU/conduct-problem variants in adolescents → supports — historical: high; evidentiary: moderate
• Fear/fearlessness equifinality study → supports — historical: high; evidentiary: high
• Neurocognitive deficits across conduct-disorder subtypes → constrains — historical: medium; evidentiary: moderate
• Cross-age neurophysiological heterogeneity study → supports — historical: high; evidentiary: moderate
