Final answer:
The term is confirmation bias, which describes the tendency to search for and interpret information in a way that confirms one's preexisting beliefs and ignores contradictory evidence. The correct option is 1.
Step-by-step explanation:
The term for an audience that has already made up their mind but believes they are objective is confirmation bias. This cognitive bias is the tendency to focus on information that confirms existing beliefs.
When people exhibit confirmation bias, they may overlook contradictory evidence, focusing instead on details that support their preconceived notions.
For instance, if someone believes a particular political policy is effective, they will likely pay more attention to data or opinions that uphold this view while disregarding information that challenges it. Confirmation bias can lead to a distorted view of the evidence and hinder objective decision-making. The correct option is 1.
