To train a ninja assassin to observe the enemy and to obtain as much useful and
specific information as possible, the ancient masters devised a "game of stones." Use
a small wooden box or shallow wicker tray and place in it stones, jewelry,
silverware, keys, coins and small household items so that the bottom is completely
covered. Now expose to a partner the uncovered container in front of your. Now
have him look at the items as long as desired and even touch and feel them. After he
sufficiently examines them, cover the container and have him relate what was see.
Check for accuracy and take time in referring to the ones he missed. Now cover the
box and have him reiterate once again everything that he saw. This time also ask him
to relate details about the container! This teaches him not to be so absorbed in detail
that the overall picture is obscured. Repeat the game until observation improves to
A college professor demonstrated to his freshman classroom the lack of
observational awareness in most people by staging a sham murder. As he began his
class, a thin, small busted, white woman (5'11") in a T-shirt and jeans, wearing a
baseball cap over short hair burst into the room and shouted, "This is a joke." She

4) What action did the assailant take?
Astonishingly, there was very little, accurate agreement among the classroom
students. Eyewitnesses to crimes are often just as unreliable.
