That 'knowledge' is structural is fairly uncontroversial. Although there are certainly different types, I would like for sake of this question to characterize (what I see as) a generalization of the concept: Knowledge are familiarity or understanding of particular items of experience. It can be communicated, though not always perfectly, and thus are sometimes "fuzzy" (people may have slightly different ideas about the facts). The more structured, the less fuzzy knowledge becomes, but then less facts are accommodated by such a structure.
When we think of "Confirmation bias" it is usually in terms of an error of induction, or a psychological propensity to misconstrue. However I would like to likewise expand and generalize the idea: In the case of psychological propensity it manifests at many different levels, from the interpretation of language to sense perception. Confirmation bias is (loosely) fitting knowables into some structure established by prior "knowledge". (If one is fanciful one may even make a case for probability distributions and other quantum phenomena)
“In visual perception, you have a process that suppresses ambiguity, so that a single interpretation is chosen, and you’re not aware of the ambiguity.” - Daniel Kahneman
Now without getting into a very long tirade, this is the hypothesis I got to:
Knowledge structures are formed by Confirmation bias.
Edit: From some of the references I've come to realize that my use of "comfirmation bias" need to be better elucidated. There is a phenomenon/process, recognizable as the same, and most apparent in the guise of confirmation bias in the areas of sociology and psychology, but also in the physical and metaphysical that for the sake of this question I will call Existential Normalization (EN). EN is then a reification of this phenomenon as distinct from knowledge, and knowledge structures, and operating on all levels from social constructs down to the aggregations of matter.
Note that now "confirmation bias" has changed from a somewhat vexing phenomenon into a sort of ontological entity. Knowledge is structured fact which is formed by EN, which is informed by Knowledge. A triad of concepts that allows for what IS to become MORE.
Question: Has anybody done something along these lines?
Why is this interesting? Most creatures aren't aware of their own biases, an awareness of one's own confirmation bias are likely a first step to Self-awareness. Also think of a DNA sequence as "knowledge"...
