““Recommendations and categorization are both useful features to seek out when trying to make a difficult decision, because they can benefit our choices in two ways. They make the decision in question easier by allowing us to borrow the knowledge of experts or crowds, and they also help us to develop our own expertise more rapidly than we would if we chose without assistance. Learning what others consider good and relevant provides us with a general overview of a given field, catalyzing our understanding of it and the development of our preferences within it.””
