text: Being biased is already having your mind made up, and not having an open mind about something like a new food. Asking someone for advise that is biased, might not give you the best advise. For example, if someone doesn't like you, and you ask them for advise, they might give you bad advise. Versus asking someone you are close to, will probably give you better advise, like a parent, which brings me to my next point.
