Is Wikipedia 'fake news'? Does Wikipedia contain 'fake news'? How would we know? Well, first of all, we need to understand the concept of fake news, and distinguish clearly between fake news and lies, truths, facts, non-facts, and bullshit. Perhaps we should begin with 'bullshit'. Harry Frankfurt's essay, "On Bullshit" explores that concept in detail, and also in a nutshell. "Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about." Frankfurt distinguishes clearly between lies - the presenter clearly does not believe what they are saying, and bullshit, where the speaker is simply talking about which they know little.
Skepticism is dead. Skepticism has been captured and converted to dogmatism. When I was young, I remember one of my cousins commenting "You are such a skeptic." It made me feel proud to be skeptical, to search for the truth. But today's, skeptics don't search for the truth. Most claim to have found it.
Skepticism has become the new religion. It's not a religion of analysis, nor thoughtfulness, nor of skepticism. It's the religion of dogma. Skepticism has been co-opted, in service of the prevailing dogma, the invisible dogma.
