It is generally never known by the rank and file if the society is lying as they never say. The rank and file accept that the society is telling the truth all the time when it is not the case, and rarely is truth ever part of anything they do.
A UBM will simply be told what the rank and file mate has been told.
Case in point of the deception used by the society, getting a brother to purchase land in a residential area knowing that he will then sell the land to the society who in turn will be denied application to build and then will sue for 'religious discrimination". They decieved the state or county and the seller and the congregation but guise it as being the 'victim of religious discrimination". They used the "theocratic warfare" tactic to explain it to the rank and file.
Or we never tell anyone they can not have a blood transfusion. Technically true, congregationally a lie....they may not say you can't but they will certainly deal with you if you do.
It is never ok for a brother to lie even if it means losing everything, but those who claim they can do no wrong never think twice of lying!
