This question appeared on Quora once. I answered it like so:
Imagine my scenario:
You’re born into a family of a Jehovah’s Witness mum and dad.
Before you can even talk you’re trained to point at the sky when they playfully ask “who made the trees?”, “who made the grass?” etc and everyone goes “awwweeee!! That’s right!”
When
you’re old enough to talk you’re encouraged to use the name Jehovah
when talking about a magic man in the sky that watches us all and loves
all of us Jehovah’s Witnesses.
At the age where
you’re told that stealing is wrong, fire is hot, strange dogs are
dangerous - you’re also told that there is a god called Jehovah and he
has a son called Jesus. And that one day Jesus will kill everybody who
isn't a Jehovah’s Witness and bring about a paradise on earth. You’re
shown pictures in Watchtower literature of non Jehovah’s Witnesses.
They’re evil. They all take drugs, sleep around, catch diseases. They
gamble, smoke, drink to excess, get involved in politics, are corrupt,
they live for pleasure and cannot be trusted. You’re also shown pictures
of the world, the world is bad, evil, dangerous and is made to look enticing
because Satan wants you to leave Jehovah. Then you’re shown more
pictures (many pictures) of Jesus killing all of these people in a thing
called Armageddon. But you’ll survive it if you become a Jehovah’s
Witness. Again, you’re told this when you’re a little child. Before your
critical thinking even has had a chance to develop.
From
the age of about 3 years old you’re encouraged to put your hand up in
the Kingdom Hall and give a one word answer in the book study or
Watchtower study. Everybody goes “awwweeee!!” and you feel validated.
You, your friends and your family all refer to your religion as “the truth”.
Cult experts recognize this as loaded language. It’s a well documented
fact that if you repeat something to yourself enough you eventually
believe it. So the idea that the religion you’re involved in ever being
wrong simply does not compute.
You’re not
allowed non JW friends. No birthday, no Christmas, no Easter, no
learning about other religions in schools, you never learned the
national anthem and you’re not allowed to study any other religious book
unless it’s published by the Watchtower Society.
By
the time you’re 12 you’ve already given many bible readings on the
platform in front of an audience of about 70 people. More than likely
you’re giving 5 min talks on various bible topics too. You’re given
validation and praise. All this time you’ve also been out every Saturday
morning and - if your family were very good Jehovah’s Witnesses, every
Sunday afternoon too - knocking on peoples doors trying to talk to them
about Jehovah and place magazines with them. This reinforces in your
mind that you have the truth because why would 8 million people do this if it wasn't true?
By
age 19 if you’re not baptized people will be wondering why, because
surely you should know this is the truth by now? If you’re not baptized
no girl will want to date you, you cant get married, your family will
keep asking you why you’re not baptized.
So you believe it. And you believe it because you know of no other life, everyone around you believes it too so it must be
right. And all the negatives about the world and people in it are blown
out of proportion and their positives diminished. So you see the world
as bad and cant wait for Jesus to destroy it and slaughter all those
evil non JWs. When somebody online or on TV criticizes or poses
questions you cant answer with Watchtower literature, or when the flaws
in the religion are exposed you become very angry and defensive. You can
feel the anger inside you like a burning blaze. This is cognitive
dissonance at work.
So simply put, in my case
is was slow, gradual, consistent indoctrination and effective mind
control from a publishing cult in New York posing as a religion.
