text: When receiving advice from someone, you may also be receiving bias towards something that affects them personally, which can be ruled out by receiving multiple perspectives. Additionally, one person may feel a strong way for or against the topic that you're wanting advice on, so having multiple perspectives on a topic will rule out that first person's biased advise, whether it was intentional or not. For example, you might be thinking about playing football (American Football) in high school, but one person begins to change your mind because they start giving you a whole bunch of one-sided, exaggerated stories about injuries caused by football, simply because they don't like the sport. Although you agree that the sport can be dangerous, you decide to get some different views on it. You go and talk to the head coach of the team, and he tells you that these injuries can be easily avoided with proper technique, mature decisions, rather than recklessness. You go to your parents as one final source of advice, knowing that they'll be neutral and unbiased. Upon receiving all of this advice, you can then make a well-informed decision on what and what not to do because you can detect the bias in the advice, now that it would act as an outlier in a larger collection.
