text: Another reason you should ask multiple people instead of one is because they might be biased. Bias is when a person is leaning towards one side of an argument because of something personal. If you ask someone who is biased in one direction then you won't be able to hear the other side of the argument. For example, when people are called for jury duty, the government chooses people that are unbiased toward the topic. By asking multiple people for their advice and opinions, you would be able avoid bias and hear both sides of the argument.
