The idea of assessment began in the battlefields of early Batesian warfare, where the victor's success was frequently due to their ability to anticipate what would come next.
Thus, Assessment evolved as a martial art based upon the observation and anticipation of one's opponent and the use of the skills learned through that observation to survive.
Over time, Assessment developed into a formalized, codified martial discipline; a means of training the mind with the same intensity as one trains the sword.
