Quizplus · Accepted Answer

Maribel is exhibiting confirmation bias, which involves looking for or interpreting information in a way that confirms one's preexisting beliefs or attitudes, and ignoring or downplaying information that does not support those beliefs. In this case, Maribel has already formed the belief that the defendant is not guilty, so she is more likely to pay attention to information that supports that belief (from the defense) and less likely to pay attention to information that contradicts it (from the prosecution).
