The purpose of those experiences on the platform at the district conventions is to make people think that the majority of their fellow members aspire to follow an artificial, spuriously-contrived standard.
It is similar to the famous sociological psychiatry experiment devised by Solomon Asch, where people were tricked into changing their perceptions to match that of what they were intentionally misled to perceive to be that of the majority. It’s really all about deception in trying to convey the incorrect idea that most in the audience would just love to quit their jobs and pioneer if they possibly could. Truth is, of course, that a very significant proportion of JWs don’t even have their Watchtower studied and underlined for the Sunday meeting – let alone have a burning desire to pioneer.
So, the next time you see one of those interviews on the platform of folks who seem to be just itching to make whatever sacrifices they can to “advance kingdom interests,” just remember that what you are seeing is merely the mirage which the WTS wants you to perceive. It’s really all just marketing fluff – and nothing more.
