This thread could be used for slicing through "truth" and "reality" from a level and angle of "fact." There probably are philosophical and scientific treatices around this topic, since "facts", "truth claims", "validity", and such designators are one favorite modern starting point for critique and for intentions to "know."
Knowing, and particularly facts that purport to populate knowledge, are a very tricky business. They touch into two privileged root philosophical inquiries, epistemology, and in the direction of ontology, both of which deconstruct much of what we think we know and what we hold dear, consciously and unconsciously.
This post and link to the Politifact site could have been placed under Edwyrd's "True and false reason thread," as "facts" so pertain and undergird, overgird, and imbue much of the analyses that are done by others. Or probably on some other threads. However, this separate thread might be a good way to slice through our senses of truth and such at this level and angle of everyday knowing, thereby, highlighting "facts."
At an everyday scale, we are inundated by "facts" in consumption and material utilization choices, in skillful work and general means & management, in life paths, wisdom searches, and in this particular season that I write, political discourse, claims, insults, and battle - e.g. the leadership elections.
I can see that, as always, there are places and ways in which bias and error and inflation of even this honesty-search process can go awry. Fairly ordinary but rather educated people who seem to intend to have much objectivity, as we know, are actually and almost inevitably subject to sources of skew and error. Yet, probably until I become aware of some egregious corruption (always relative,) I am glad for what they do. Good effort - probably little impact [grimace.]
Here in the attached file is one part of the standards that aspires towards making valid discernments and judgements. These principles (and others that you may want to read) give me a good resonant and common-sense feel, as a starting point.
