text: Using advice from multiple people also helps you to avoid bias. If you had a very strong opinion on something, and you seek the advice of someone who thinks the opposite of you, you get a better understanding of why they think that way and can avoid bias. Some important choices cannot be made with any bias, for example if you owned a company and needed to pick employees to hire picking your niece who as no experience in the field, nor any desire to work at your company is not a good choice. However using advice from other workers who help run the company you could find someone to pick with more experience and with desire to work there. Bias in this case would not be good for your choice, so using others advice you can avoid it.
