Course-correction latency is one of the most telling measures of a field’s navigability:
How long does the field continue moving in a direction after credible evidence indicates the course no longer corresponds to conditions?
Organizations, governments, and individuals can be catastrophically bad at this — continuing to execute flawlessly toward a destination that stopped making sense, because reversing course threatens identity, sunk investment, or status. It is the navigational form of the model’s broader concern with drift: the gap between a trajectory turning wrong and the turn actually being made. Like the other function measures it assesses the field, never an individual — there is no “bearing score” — and it pairs with horizon breadth (how many viable futures a field can perceive) as the two readings that tell you whether a system can still change direction when it needs to.
