Neural and Mental Capacities

The failure to demonstrate our knowledge through our actions may be one of the most important defects of human nature. Indeed, it may be a rate-limiting condition for our species. In many circumstances, we know much more than we demonstrate. Recognition of this fact is the basis of the common complaint of the student who did not do as well as expected on an examination. “I knew the answer but couldn’t get it out.” The student is often correct. The complaint may not be merely rationalization of a failure to study or learn. The conditions of the test, events of the past few days, a heightened emotional state, or other factors may conspire to prevent what is known from being made concrete through expression. Another time, another day, another place, the test may have been passed.
