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

The assertion that we never block out information is not entirely accurate. While it's true that individuals may have difficulty accepting information that contradicts their preexisting beliefs, the nature of our cognitive processes suggests that we often engage in selective perception or confirmation bias. This means that we may pay more attention to information that aligns with our beliefs while disregarding or underestimating information that challenges them.

Cognitive dissonance theory explains that when people are confronted with information that conflicts with their beliefs, they might experience discomfort, leading them to avoid or diminish the impact of such information. Therefore, while it is not correct to claim that we never block out information, it is also not accurate to assume we do so completely. In fact, research supports that individuals are likely to have varying thresholds for acknowledging information based on their personal beliefs, which aligns more closely with the idea that we tend to filter information based on its congruence with our beliefs.

Thus, while the option chosen might reflect a perspective that overlooks the complexity of cognitive processing, understanding the nuances of how beliefs influence information retention is vital.
