Hick’s Law is often either referenced directly or alluded to by many “reality-based” self-defense practitioners. It is one of the core principles at the foundation of Krav Maga and one of the main reasons why Krav is such an effective system. Hick’s Law, or the Hick–Hyman Law, “describes the time it takes for a person to make a decision as a result of the possible choices he or she has”.
If we simplify the formula at right, it looks more like this:
ReactionTime = MovementTime + ProcessingSpeed • log2(n)
ProcessingSpeed • log2(n) is the time taken to come to a decision and n is the number of choices
