Do we block out information if we already believe it is true?

The concept of cognitive bias plays a crucial role in how we process information, particularly in relation to our pre-existing beliefs. When individuals have a strong belief about a subject, they tend to filter incoming information through that belief. This phenomenon is often associated with confirmation bias, which leads people to favor information that supports their views while disregarding information that contradicts them.

In this context, the idea that we never block out information is misleading. While it's true that we may not completely block out all information that contradicts our beliefs, we often give less weight or significance to that information. Individuals frequently interpret or reframe contradictory data in a way that aligns with their existing beliefs, rather than acknowledging it objectively.

Therefore, the focus should be on the tendency for people to resist information that challenges their established viewpoints rather than concluding that we have an absolute openness to all data regardless of our beliefs. This subtlety highlights cognitive biases but fails to capture the complexity of how we interact with new information, particularly when it conflicts with what we already hold to be true.
