One of the first things that shocked me when learning the truth about the truth was how the organisation uses tricks and deception to fool their own membership. I guess we all have our own favourite examples, like the quotes in the publications that make outside sources look like they oppose the Trinity/support the NWT/disprove evolution, when in context the intent of the original source is quite different. Or the grossly exaggerated experiences delivered at conventions: if we happen to know the person or were present at the events described we know it's often garbage what they say on stage, more closely resembling a desired script emanating from headquarters than anything that actually happened to real Witnesses in the circuit or district.
But there is another example I seem to recall, I thought was quite interesting, and I am looking for corroboration.
Another deceptive tactic Watchtower writers have used is to quote themselves without telling the reader that's what they are doing. For example when some encyclopaedias are compiled they may ask JWs at the branch to provide information for their own entries. Hardly a great practice for a supposed impartial reference work, but apparently it does happen. Which is how you end up with The Encyclopedia Canadiana saying something like this:
"The work of Jehovah's Witnesses is the revival and re-establishment of primitive Christianity practised by Jesus and his disciples ... All are brothers."
Which JW writers then in turn quote in the publications, such as in the Kingdom News tract called "Will All People Ever Love One Another?" And regular JWs think: "wow, even secular writers and authorities recognise that about us, it must be true!" Not realising it was actually a brother at the branch who wrote the glowing comment in the first place. Pretty sneaky if you ask me.
