Be that as it may, just because one is engaging in speculation or imagination does not mean the perspective through that speculation is inaccurate. While I may not know from direct experience what it may be like to walk on Mars, and I have no direct experience with the 'facts' on the ground there, the anecdotal evidence I've studied strongly suggest that the conditions there offer good reason not to go walking about in shorts and a t-shirt. I know it's still just speculation but is useful just the same.
On the other hand just because someone is citing what they believe to be 'facts' does not mean their interpretation of those facts is accurate. There has been many a false conclusion made on misunderstood, misrepresented, or insufficient facts.
In either case there are beliefs at its core, and beliefs are regarded as truth to the one who believes. Furthermore, our beliefs may be accurate, or may not. As individuals, beliefs are the filters through which we live our lives.
