Urde una mezcla perfecta de realidad y ficción: Estrategia de falsa percepción

WEAVE A SEAMLESS BLEND OF
FACT AND FICTION
MISPERCEPTION STRATEGIES

Since no creature can survive without the ability to
see or sense what is going on around it, you must
make it hard for your enemies to know what is going
on around them, including what you are doing.
Disturb their focus and you weaken their strategic
powers. People's perceptions are filtered through
their emotions; they tend to interpret the world
according to what they want to see. Feed their
expectations, manufacture a reality to match their
desires, and they will fool themselves. The best
deceptions are based on ambiguity, mixing fact and
fiction so that the one cannot be disentangled from
the other. Control people's perceptions of reality and
you control them.
Robert Greene

At the end of the war, Allied Intelligence Officers
discovered in captured files of the German
Secret Service the text of two hundred and fifty
messages received from agents and other
sources before D-Day. Nearly all mentioned
July and the Calais sector. One message alone
gave the exact date and place of the invasion. It
had come from a French colonel in Algiers. The
Allies had discovered this officer was working for
the Abwehr and he was arrested and
subsequently turned round. He too was used to
mislead Berlin--used and abused. The
Germans were so often deceived by him that
they ended by treating all his information as
valueless. But they kept in contact, for it is
always useful to know what the enemy wants you
to believe. Allied Intelligence, with great
boldness and truly remarkable perversity, had
the colonel announce that the Invasion would
take place on the coast of Normandy on the 5th,
6th or 7th June. For the Germans, his message
was absolute proof that the invasion was to be
on any day except the 5th, 6th or 7th June, and
on any part of the coast except Normandy.
