“Yet the individual is handicapped by coming face to face with a conspiracy so monstrous he cannot believe it exists. The American mind simply has not come to a realization of the evil which has been introduced into our midst. It rejects even the assumption that human creatures could espouse a philosophy which must ultimately destroy all that is good and decent.” -FBI Director J. Edgar Hoover, The Elks Magazine, August 1956 1956 Elks Hoover OCR.pdf pg7.
Perhaps we shouldn't really believe anything? Why not research a topic so that you can present all sides equally well? Sometimes, while researching, you discover one side is being deceptive, secretive or worse. Sometimes, you'll encounter information that has been well hidden and that knowledge will make it impossible to believe exactly what you previously did. To be fair, if you can't factually represent your opponents arguments against your position, you have no real reasons to prefer your position to theirs - you don't know what they've got to reveal, you arrogant twit.
Rather than being a "believer" in things, why not seek to understand and state what truth can be discerned and exactly how it was obtained, no matter what it reveals? You should not be attached to any position other than the truth. If you can disprove me, then I'll thank you for advancing me along this path. If you look closely, you'll see that belief and faith are actually measures of desire for something to be true or signs of bias, intentional or otherwise. Be careful as the line between belief and knowledge is a thin one and drawn by yourself and there are many who claim to know something that just isn't true.
"Beware of false knowledge; it is more dangerous than ignorance" ― George Bernard Shaw.
For me, remaining skeptical while maintaining an open and curious mind and welcoming all sources of information is the proper path. It allows me to receive information counter to my accepted narrative, and be thankful, rather than angry or defensive. Anyone providing me valuable assistance by articulating their position and helping me gain a better, more complete understanding of the issue should be thanked.
“What is wanted is not the will to believe, but the will to find out, which is the exact opposite." ― Bertrand Russell
One thing I have found is that truth-seekers are rare.
