YESTERDAY?!
IN THE EARLY 1900S, a horse called Clever Hans
becáme a German celebrity! Touring Germany's town & villages,
HANS SHOWED OFF A REMARKABLE GRASP OF THE GERMAN LANGUAGE,
ÀND AN EVEN MORE REMARKABLE MASTERY OF MATHEMATICS? When asked,
'Hans, what is four times three?' Hans tapped his hoof twelve times!
When shown a written message asking, 'What is twenty minus eleven?' Hans tapped nine times,
with commendable Prussian precision! Thus in 1904 the German board of education appointed a special
scientific commission headed by a psychologist to look into this matter! The thirteen members of the commission
- which included a circus manager & a veterinarian - were convinced this MÙST be a scam, but despite their best
efforts they couldn't ùncover any fraud or subterfuge? Even when Hans was asked what is 4 times 3, he knew
from past experience that the human was expecting him to tap his hoof a given number of times. He began
tapping, while closely monitoring the human. As Hans approached the correct number of taps the human became
more and more tense, and when Hans tapped the right number, the tension reached its peak. Hans knew
how to RECOGNISE this by the human's body posture and the look on the human's face.
He then stopped his tapping, and watched how tension was replaced by
amazement or laughter? Hàns
knew hé hàd
got it
right.
