There was a certain wealthy man, a prominent citizen, who was about to
sponsor a public entertainment. He invited anyone who had some novelty to
perform, promising to pay them a fee. Professional performers came to compete for
public acclaim, and among them was a clown [Parmeno] who was well known for
his sophisticated sense of humour. He said that he had a type of spectacle that
had never been performed in any theatre before. The rumour spread throughout
the city, sparking the public's interest. Theatre seats that had recently been
left empty were now not enough for the gathering crowd.
After the clown came out by himself on the stage, with no equipment and no
assistants, a hush of anticipation silenced the spectators. Then the clown
suddenly lowered his head towards his chest and imitated the sound of a little
pig. The sound was so true to life that the audience maintained that there
must be a real little pig concealed under his cloak and they demanded that it
be shaken out. But when the cloak was shaken out, it proved to be empty, so
they lavished the clown with praise and he left the stage to resounding
applause.
A country bumpkin saw what had happened and said, 'By gosh, I can do better
than that!' He immediately promised that he would do the same thing, only
better, the following day. The crowd grew still larger and favouritism had
already swayed their perception; you could tell that they had not come to
watch the performance so much as to make fun of it. The two men came out onto the
stage. The clown squealed as he had done the day before, provoking the
audience's applause and shouts of approval.
Now it was the turn of the country bumpkin, who pretended to conceal a
little pig beneath his clothes -- and this time there really was a hidden pig,
although of course the audience had not found anything under the clown's cloak
at the previous performance. The man then pulled the ear of the real pig that
was hidden in his clothes, producing an authentic squeal of pain.
The audience shouted that the clown had given a far more realistic
performance and they were prepared to drive the country bumpkin off the stage.
But he then pulled the actual pig from inside his cloak and showed it to the
audience, denouncing their gross error with incontrovertible evidence. 'Here
you go!' he said. 'This little pig proves what kind of judges you are!'
The moral of Aesop’s fable is that people’s expectations, positive or
negative, can powerfully distort their perception of things. The philosopher
Plutarch refers to this fable and comments that, ?it is very obvious, that
similar sensory stimuli do not always create similar responses in the mind
when there is a belief that the thing done was not skillfully and ingeniously
performed.? (Essays & Miscellania, 5:1)
The performer Parmeno is a confident and charismatic performer, surrounded
by an aura of expectation. He fools the audience into believing that his
impression of a pig is better than the real thing, they hear what they want to
hear. The bumpkin is damaged by a negative expectation, despite using a real
pig the audience are still convinced that his performance is inferior.
Cognition trumps sensation.
