Review Questions

• How does confirmation bias affect the way individuals evaluate and verify sources of information?
  • Confirmation bias leads individuals to prioritize information that supports their existing beliefs while neglecting evidence that contradicts those beliefs. This selective attention can cause people to disregard credible sources that challenge their views and only seek out data that aligns with what they already think. As a result, their evaluation of sources becomes biased, impacting the overall accuracy and reliability of the information they accept.
• Discuss strategies that can be implemented to mitigate the impact of confirmation bias when assessing different sources of information.
  • To mitigate confirmation bias, individuals can adopt strategies such as actively seeking out opposing viewpoints, engaging in discussions with others who have different perspectives, and deliberately exposing themselves to a variety of sources. This approach encourages critical thinking and helps counteract the natural inclination to only affirm one's beliefs. Additionally, using structured evaluation criteria for sources can aid in objectively assessing the credibility and relevance of information.
• Evaluate the consequences of confirmation bias in journalism and how it can affect public perception and understanding of important issues.
  • Confirmation bias in journalism can lead to skewed reporting and the reinforcement of misinformation. When journalists allow their biases to dictate which sources they include or exclude, it results in incomplete narratives that fail to provide a comprehensive view of issues. This not only misinforms the public but also contributes to polarization by deepening existing divides among audiences who consume media that aligns with their beliefs. In turn, this can undermine informed decision-making and weaken democratic processes.
