"So do you think people cannot be rationally honest?"
Close, I believe that it's extremely difficult for someone to be near-wholly rationally honest. Our brains don't have the capacity to catch every premature assumption and come to every logical conclusion without bias. The result is, I think, that one in ten thousand people have a mostly correct belief system (and one in ten thousand of that ten thousand have it due to unbiased reason) and that about one in one billion imagine it mostly correctly too.
"I disagree it only takes a major consensus to be a world view"
Not what I meant. That was supposed to be sarcastic, in context of how I said that every worldview claims to be intellectually honest.
Though, my typical definition of worldview means that it has to potentially exist to be a worldview (for example, if nobody believed in Marxism, it'd still be a worldview) and that there are about 8.28 billion different worldviews in the world right now, because everybody's view of the world differs, even in the slightest of ways. If you defined worldviews as general umbrella worldviews, (like marxism, secular humanism, Christianity, etc.) You're mostly right, though I would still say the worldview only has to be potentially existent.
