People value what makes them feel good, and they want to believe what makes them feel good is the truth, so they will value some bullshit artist, that makes them feel good, even more when he lies to them that he is telling them the truth.
People are hard-wired to feel good. Some people feel good by knowing the truth, and some people will chance fanciful lies and call them true, because that is what makes them feel good.
None of this is conscious effort. This is all wired at the subconscious level. Only by understanding this can anyone hope to pull it to the conscious level, and even then the wiring fights with us, because the wiring is animal instinct and biochemistry and it is amoral and doesn't give a fuck about anything but feeling good.
