Confirmation Bias 

The natural human tendency to hold opinions that agree with one's own point-of-view as more valuable than opinions that do not. However, this can be magnified to an insane proportion in ignorant people, overly-religious people, people who have power, people who think they have power, people on a power trip, and people who hate criticism in general. This may stem from a fear of change, what one does not know, or from an OD god complex.

Most 4chan users have an off-the-wall confirmation bias.

Confirmation bias confirmed

Well that was about what I expected.

Hym "So, confirmation bias confirmed. I mean, it didn't even really require any research at this point."

Confirmation Bias Realism

The pragmatic, Kant-informed position that while our reality is indeed filtered through innate and learned biases, this is realism for us. We cannot escape our confirmatory frameworks, so the "real" world is the one we collaboratively construct and confirm through shared biases (cultural, scientific, linguistic). Truth is a high-stability confirmation bias agreed upon by a community.

Example: The scientific method is the ultimate expression of confirmation bias realism. It doesn't claim to find bias-free truth, but a stable, inter-subjective truth by making our biases (hypotheses) explicit and rigorously testing them against a shared reality, creating a consensus confirmation that we accept as "real."

Confirmation Bias of Everything

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.

Example: After a surprising scientific discovery that overturns a theory, someone dismisses it by saying, "The new data only 'confirms' the scientists' hidden bias toward novelty. They were biased to find a change, just as the old guard was biased to find stability. It's all just confirmation bias of everything." This nihilistic take uses epistemology to void empirical evidence entirely.

Confirmation Bias Blind Spot

The cognitive inability to recognize one's own confirmation bias while easily detecting it in others. This is the meta-bias that makes confirmation bias so resistant to correction. You can see how your political opponent selectively reads news; you cannot see how you do the same. The blind spot is structural: self-awareness requires a neutral vantage point, but there is no such vantage point. You cannot step outside your own confirmation processes because those processes are what constitute your reasoning.

Confirmation Bias Blind Spot Example: "I read diverse sources and follow the evidence wherever it leads. My opponent, however, lives in an echo chamber." This statement, sincerely believed, is the Confirmation Bias Blind Spot speaking. The speaker cannot perceive the filters they apply—the choice of which "diverse sources" to trust, which "evidence" to weight heavily, which conclusions "logically follow." Their bias is not in their data; it's in their algorithm for processing data. And algorithms cannot see themselves.

Confirmation Bias of Common Ground

The shared, tacit assumptions that enable communication and cooperation within a group, maintained by collective confirmation. When everyone in a community starts from the same axioms and continually reinforces them through discourse, the axioms become "common ground"—so obvious they need not be stated. This bias is functional: it reduces negotiation costs and enables coordinated action. It is also a prison: it makes the group's foundational premises invisible and unassailable from within.

Confirmation Bias of Common Ground Example: In a corporate meeting, everyone confirms that "shareholder value" is the ultimate goal. This common ground is never debated; it's the platform upon which all other debates happen. An outsider asking "Why maximize shareholder value?" is met with confused silence—they've violated the Confirmation Bias of Common Ground. The group's bias is so deeply shared they've forgotten it's a bias.

Confirmation Bias of Common Sense

The process by which certain beliefs become elevated to the status of "common sense" precisely because they have been confirmed so often, by so many, for so long, that their confirmation is no longer visible as an active process. Common sense feels like direct perception of reality, not a hypothesis, because its confirmation history is buried in cultural memory. This bias hides the contingency of these beliefs, making alternatives seem not just wrong, but insane. Common sense is the ghost of confirmation bias after it has become invisible.

Confirmation Bias of Common Sense Example: In 1700, it was common sense that the Earth was young and that kings ruled by divine right. These weren't beliefs; they were the backdrop of reality. Questioning them was folly. Today, common sense includes human rights and germ theory. Confirmation Bias of Common Sense reveals that yesterday's common sense was just a massively confirmed hypothesis, and today's will be tomorrow's historical curiosity. The bias is in forgetting that all sense was once nonsense.
