Type Eight self-preservation is a traditional, evidence-limited hypothesis combining Type Eight autonomy with material control, territory, direct needs, resource access, survival, and practical autonomy. Provisioning or guarding does not establish subtype because scarcity, housing risk, disability access, caregiving, dangerous work, property duty, and prior theft may require the same behavior.
The tradition proposes that autonomy attention may focus on securing supplies, access, space, and direct satisfaction of practical needs. Observe who benefits and what happens after material stability returns.
Hold household duties similar across a scarce period and a stable period. Record keys, money, food, transport, storage, permissions, and whether shared governance expands when real risk decreases.
Self-preservation here is a traditional label for resource and continuity attention, not evidence about bodily mechanisms. Health, nutrition, disability, violence, and housing danger need direct factual assessment.
A person may provide abundantly while retaining final control, or live simply while defending a small territory intensely. Neither spending level nor visible toughness establishes the proposed function.
Poverty, eviction risk, theft, dependent care, disability access, hazardous employment, disaster recovery, and unequal legal protection can make resource control adaptive and necessary.
The hypothesis weakens when stable access leads to shared keys, transparent budgets, delegated purchasing, flexible space, and willingness to rely on another competent person without retaining override.
This subtype cannot rank resilience, financial ability, health, toughness, or property rights. Instrument-specific evidence does not establish universal subtype structure or cross-cultural equivalence.
Duration: 5
Context: Over five days, compare one constrained-resource decision with one adequately supplied decision under similar household responsibility.
Observable signal: List who controls keys, money, food, transport, storage, permissions, risk evidence, shared requests, and any authority released after access improves.
Page-specific signal: Measure whether practical control persists when scarcity and immediate danger are demonstrably reduced.
Alternative explanation: Review eviction risk, theft, disability access, caregiving, hazardous work, disaster recovery, and unequal legal protection.
Reflection prompt: Name the resource change that best explains control, then reduce the subtype hypothesis if shared access follows stability.

The 104-sample review combines heterogeneous instruments and does not validate FermatMind, establish universal nine-factor recovery, or support deterministic individual typing.

Historical theory language, including clinical-sounding labels, is not contemporary diagnosis, causal evidence, or validation.

The predominantly female, highly educated Turkish sample and instrument-specific results do not establish cross-cultural universality, subtype ontology, or FermatMind equivalence.

Compare who controls access after conditions stabilize.
Record the physical or digital boundary, legal responsibility, stated risk, people excluded, conditions for access, and whether control relaxes once the risk is addressed.
Transparent budgets, shared keys, delegated purchasing, and reliance on another competent person after scarcity resolves all weaken a persistent material-control interpretation.
