https://www.youtube.com/watch?v=L9NOIoLegqg - Hillary advisor lying through her teeth to newscaster who knows it. Note the rehearsed friendly tone, the forced smile.

When I see a person who carries themselves this way and speaks this way I immediately distrust them, because this is the demeanor of someone whose job it is to seem trustworthy without being trustworthy.

Does anyone have any idea why people might think this behavior makes them seem trustworthy?
