Ever hear an experience at an assembly that you KNOW wasn't slanted?
The problem is that the WTBTS instructions as so specific ( " interview a young pioneer couple who have simplified their lives and reduced their workload to put kingdom interests first " ) that it is very difficult to organise an interview without having to get the participants to spin it.
The worst I saw was when a brother & sister in our congregation was interviewed at the circuit assembly and the sister said that her children had accidentally "come along - as it happens" so she had reluctantly had to give up pioneering for a few years. This was a total lie , as her & her husband had been desperately trying for years to have children , and the sister had actually had a couple of miscarriages before she finally was able to start having children. There was also a lot of other rubbish in the interview , to give the false impression that the couple were very "spiritual" ( in reality , they were a very self - righteous couple who had fallen out with most of the congregation). My wife actually got up & walked out before the interview was concluded , as did a couple of other members of the congregation.
I was an elder at the time & afterwards spoke to the brother who conducted the interview afterwards and told him angrily and listed point by point the lies in the interview. He was a bit shaken up by it and admitted that he had really struggled to get anyone in the whole circuit he could interview that met the WTBTS qualifications. I told him that regardless of that , it was completely unethical to encourage a couple to lie to the whole circuit.
My parents were interviewed at the District Assembly & my father said that he had always conducted a regular family study while the children were growing up. In reality , we never had a regular study - probably only had one every year , usually before a circuit visit. I asked him afterwards why he falsely claimed this and he said that the CO interviewing him had insisted that he should make that assertion , regardless of its veracity , as it was in the outline.
