This… while we are all baffled by Trump’s alleged lies.
Another reason for promoting lying is what economists sometimes call loyalty filters. If you want to ascertain if someone is truly loyal to you, ask them to do something outrageous or stupid. If they balk, then you know right away they aren’t fully with you. That too is a sign of incipient mistrust within the ruling clique, and it is part of the same worldview that leads Trump to rely so heavily on family members.

This doesn’t just happen in politics. There are always ‘ruling cliques’ in business, charities, churches… and this is one of the ways they behave.
