Definition

The rapid differential is RB3’s sequence of orienting questions for acting under pressure: identify the ethical object, scan temporal constraints, locate leverage, detect lock-in, limit irreversible contraction, attach feedback and return to reconstruction. The proposal preserves its role in disciplining situated judgment without pretending to eliminate uncertainty, compute one guaranteed answer or replace the slower ethical method.

Explanation

The first questions distinguish a local act from a regime node and read irreversibility, temporal mismatch and threats to judgment. Capacity-mapping then asks what the agent can actually change with others. This prevents the method from turning every structural problem into a test of private virtue or assigning all causal participants identical duties.

The next steps inspect what defaults and selection criteria may become infrastructure. Least damage is assessed against plural viability, domination and capture, not only immediate output measures. The source supplies a normative orientation rather than a mathematical optimization rule, preserving the possibility that several constrained actions remain contestable.

Feedback can include revisable deployments, appeals, audit trails or permission to stop where feasible. The final step explicitly returns to diagnosis and redesign after the emergency. These are the book’s practical proposals, not instructions to execute upon this project or a certification that any particular institutional safeguard will always work.

Scope and attribution

A rapid orienting sequence supports judgment under uncertainty and must return to reconstruction; it is neither an optimizer nor project-execution instructions.

Background used in the editorial explanation

RB3 p.297 introduces general evaluative axes. Rapid differential judgment is established by its substantive development elsewhere; passing return-to-reconstruction references alone were not added.
