"Everybody lies," is a classic House M.D. aphorism. It’s scientifically true. Even if we think we’re being truthful there’s still a chance that our brains are lying to us. This is called source amnesia. And political campaigns are more than happy to exploit this scientific fact.
So let this be a warning to all of us. Our human tendency to categorize (Platonicity) and explain the causes of everything with theories (narrative fallacy) backed up with partial evidence (confirmation bias; fallacy of silent evidence) while concocting models of reality (ludic fallacy), coupled with a brain that lies to us, make us blind to the truth.
Fine. So what is there left to believe?
I don’t know. All I know is that I’m aware at this very moment of both truth and lies, and everything in between. Ignorance is sooo underrated.
