Utility

The idea
A utility is a number an agent assigns to an outcome, measuring how much it matters — one scale, so unlike things can be weighed.
In practice
Two job offers — more pay against a shorter commute — become comparable once each whole outcome is priced on the scale of caring.
Where people slip
Utility does not discover the price; it records the agent's own valuation, made explicit.
