Recognizing the tremendous importance of timing, Japanese martial artists classify their responses into three types:

• Go no sen refers to a late reaction, initiated after the attacker’s movement has begun. Late reactions are unreliable, relying on extraordinary motor speed for their successful application.
• Sen no sen describes a response launched roughly in time with its attack. While obviously superior to go no sen, some practitioners consider this an intermediate level of skill.
• The ultimate timing, sen-sen no sen, responds to an attack that has yet to be launched, one that has only just formed within the opponent’s mind. An expert in sen-sen no sen might use this timing to guide his assailant into a futile and vulnerable position, or launch a preemptive strike.

Martial legends aside, how does science explain this seemingly paranormal ability? Is it possible that high-level martial artists have used precognition and other psychic abilities to enhance their effectiveness? Or are they all just very quick? [Read more →]

It seems my critics are right: I am a little slower than average.

Patrick Parker (of Mokuren Dojo) and I were discussing the feasibility of intelligent responses to physical attack. Patrick asked:

What exactly do you have to do to get the faster intelligence that Chris says we need? Well, really we can’t. From my understanding of the neuromuscular machine I don’t really think that you can make the brain/spine/muscle machine work faster than it already does. There is hardwired into us about a ¾ second delay (if not more) in the OODA loop.

A search for evidence supporting or refuting this unavoidable delay, led me to the Human Benchmark reaction time test. [Read more →]
