The cognitive flaw where an individual is hyper-vigilant and excessively critical about potential biases, methodological weaknesses, or assumptions in opposing viewpoints or rival paradigms, while remaining completely oblivious to the same—or even more severe—flaws within their own favored position. It inverts the classic blind spot: you can't see the problems in your own "objective" lens because you're so busy polishing it to spot dust on everyone else's.
Example: A staunch materialist neuroscientist meticulously critiques a consciousness study for any hint of dualist language, labeling it unscientific. Yet, they remain utterly blind to their own Inverted Blind Spot Bias: their unexamined assumption that subjective experience must be fully reducible to neural activity is itself a non-provable metaphysical stance, not a neutral scientific fact.
