# EndogenousStress

The internal load a system carries from being partly prepared for possible external stressors

Layer: Mind · Category: Strategy

## Mechanism

In a [FractionalMetaModel](https://mindscape.pages.dev/origin-of-risk/FractionalMetaModel.md), functions prepared for a possible [ExogenousStress](https://mindscape.pages.dev/origin-of-risk/ExogenousStress.md) are partly built: data processed through two pipeline stages but not the third, passwords memorable but not yet valid, components readied for a server failure. This preparedness costs effort without yet producing output, and it shows up as friction, a raised [ComputationalEntropyRate](https://mindscape.pages.dev/origin-of-risk/ComputationalEntropyRate.md) in the system's channels. That internal load is endogenous stress. Its rational level rises with the likelihood of the exogenous stressor: the more likely the event, the more partial preparation is worth carrying, because completing a function then takes only a small change. A system can be over-stressed (carrying preparation for stressors that will not come, which should be removed) or under-stressed (unprepared for likely stressors, which should be built up). Stress is thereby a measurable technical quantity in software, organisations and cells, not only a description of a biological pathway.

## Invariants

- Endogenous stress is proportional to the partly built functions a system carries
- Its rational level rises with the likelihood of the corresponding exogenous stressor
- High endogenous stress means a small change completes the prepared function

## Failure modes

- Eliminating all internal friction as inefficiency and so removing preparedness
- Carrying preparation for stressors that have become unlikely
- Measuring stress only as a symptom, not as information about expected exogenous stressors
