# RegretMinimization

Safety-first decision making based on loss avoidance

Layer: Mind · Category: Strategy

## Mechanism

[Decision](https://mindscape.world/scapes/bootstrap/Decision.md)-making based on minimizing the maximum possible loss (emotional safety/Minimax) rather than maximizing expected value (Utility/Kelly). Useful for survival-critical contexts. It factors [OpportunityCost](https://mindscape.world/scapes/bootstrap/OpportunityCost.md) into the loss function, selecting the path with the least damaging worst-case scenario.

## Invariants

- Pessimism: Assume worst-case outcome for each branch
- Safety Floor: Never choose option with catastrophic worst-case

## Failure modes
