The Science of Becoming More Adaptable

Autonomic flexibility (the ability to shift between sympathetic and parasympathetic states quickly). Interoceptive accuracy (the ability to read the signal). Prediction-error tolerance (the ability to update the internal model when reality diverges). Recovery speed (the ability to return to baseline). All four are trainable.

Sustained aerobic conditioning trains autonomic flexibility. Interoceptive attention practice — including within movement — trains signal-reading. Deliberate practice under load trains prediction-error tolerance. Adequate sleep and recovery train recovery speed. Nothing in this list is exotic.

Adaptability is not who you are. It is what you have practiced. Which means the person who fears they are “not the adaptable type” is describing a Framework, not a fixed trait. The science says the Framework can move.
