text: Sometimes asking just one person is not enough. Having several perspectives can help you lean towards a decision easier, because if most people agree with one way to make a decision it makes you more comforted to agree with them aswell. For example, you are picking what college you want to attend and are torn between two choices. You talk with an alumni of one of the schools and they said its the best school you could ever go to, you ask a group of people and most of them go with the same option because it will bring you better opportunity. You are now more convinced to choose that school because most people think it would be the best decision for you.
