Can repetition create truth?

All that was needed
was an unending series of victories over your own memory.

George Orwell

Can thought be controlled by repeating positive messages,
while underreporting negative,
and vice versa?

Men… think in herds,
it will be seen that they go mad in herds,
while they only recover their senses slowly…,
one by one.

Charles Mackay

With a little help,
can most convince themselves of just about anything?

Insanity in individuals is rare,
but in groups, parties, nations and epochs it is the rule.

Friedrich Nietzsche

If a percentage of what you think,
may be what some frequently suggest you think
could a good chunk of what many others think
be what they have been told to think,
right up until they may not think what they thought anymore?
