Which bias involves seeking or valuing only supporting evidence while ignoring disconfirming evidence?

• A. Confirmation bias
• B. Anchoring bias
• C. Automation bias
• D. Omission bias

Answer: (A)

Confirmation bias is the tendency to favor information that confirms what you already think and to disregard or undervalue evidence that would disconfirm it. The scenario describes exactly that: you seek out or give more weight to data that supports your belief while ignoring or dismissing evidence that would challenge it. This leads to biased conclusions because the evaluation isn't weighing all relevant information fairly.

Anchoring bias would involve sticking too tightly to an initial piece of information as a reference point. Automation bias is about over-trusting automated systems. Omission bias centers on preferring inaction to action due to fear of potential harm.
