A philosophical dead-end stemming from a misreading of Kant, which asserts that all human perception and cognition is nothing but confirmation bias. Since we can never know the "thing-in-itself" (noumenon) and only interpret phenomena through our mental categories, this view claims every observation is simply confirming the pre-existing structures of our mind. It’s a radical skepticism that makes genuine learning or surprise impossible, reducing all experience to a tautological loop.
