Confirmation bias is the tendency for individuals to seek out information that aligns with their pre-existing beliefs and to interpret evidence in a way that supports those beliefs. People readily accept information consistent with their views but are skeptical of contradictory information.
A study showed that teachers given false information about certain students' potential gave them more praise and attention. This led those students to improve more, demonstrating how confirmation bias can create self-fulfilling prophecies, making people prove themselves right.
Physicians might focus on evidence supporting an initial diagnosis, ignoring equally plausible alternatives. Similarly, police officers adhering to stereotypes might process clues in a biased way when investigating suspects. Even scientists can disregard inconsistent facts to protect their theories.
Confirmation bias can lead to inaccurate and unethical conclusions. It is crucial to acknowledge our susceptibility to this bias and actively combat it by being open to evidence that contradicts our beliefs and theories.
