Definition
Hardwired biological constraints are enduring limits from anatomy, chronotype, injury, or development — design around them, do not moralize them.
Genetic variance contributes to behavioural outcomes, but heritability estimates do not map cleanly onto individual ceilings — environment and training still reshape expression within real limits.
Mechanism
| Layer | Move |
|---|---|
| Floor | Anatomy, chronotype, injury history — design around, do not moralize |
| Trainable band | Skill, sleep, load — still large inside the floor |
| Fantasy ceiling | Ignoring the floor guarantees shame cycles |
Behaviour genetics describes population variance, not a personal destiny score — ambition stays honest when the floor is named early.
Applications
Pair with Hormesis and deliberate adversity: train inside real constraints, not fantasy baselines.
