People tend to have a faith in confidence. When people say things confidently enough people tend to believe them. Shitty people have no problem confidently lying or misdirecting for personal gain.
You can also see this with stupid people having jobs way above their competence level. Stupid people don't know enough to question their ability. "I got this, how hard can it be?" Lot of politicians end up here it seems. They seem nice on the outside. They sound confident in their soundbites. But if you try to sit them down for intelligent conversation you suddenly realize why the world is in such a sorry state.
