How does confirmation bias affect decision-making?

• A. It leads individuals to gather more information.
• B. It encourages a balanced consideration of all evidence.
• C. It leads individuals to favor information that confirms their existing beliefs.
• D. It promotes critical thinking in judgment.

Answer: (C)

Confirmation bias significantly influences decision-making by causing individuals to favor information that aligns with their pre-existing beliefs or hypotheses. When faced with new evidence or data, individuals are more likely to seek out, interpret, and remember information that supports what they already think, rather than considering opposing viewpoints or contradictory evidence. This selective attention can create a distorted perception of reality, leading to flawed conclusions and reinforcing erroneous beliefs.

For instance, in a situation where someone holds a strong opinion about a political issue, they might only pay attention to news articles or studies that support their viewpoint, while dismissing or undervaluing information that challenges it. As a result, their decision-making process becomes skewed, potentially leading to a more polarized stance on the issue.

In contrast, strategies that involve gathering more information, considering all evidence, or promoting critical thinking are counteractive to confirmation bias. These approaches encourage a holistic view of the situation, helping to mitigate the effects of bias on judgment and decision-making.
