Good point, I agree , people always want to be with the "winning team". And it's not just social proof, we are also dealing with the fact that they claim to be led by God. They simply cannot afford to have people think they miscalculated or made a mistake, as it proves they are not specially appointed and being directed by God.
It's also ridiculous, they started projects they now cannot finish, wasting money on half built buildings. They are trying to put a good face on it, but that is not good financial management, they just screwed up, only a deluded cult member wouldn't know that. Unfortunately there are a lot of deluded cult members.
