While looking at knowledge, the social, cultural, and personal background need to be taken into account. Such factors can affect since there are different perspectives. Furthermore, how the knowledge is acquired, the methods and tools used to do so, are vital too since they can have a significant impact. For example, if I heard some information about my friend from a third party, the third party's bias regarding my friend (whether she likes her, approves of her actions, etc) can affect the information relayed. Hence, this needs to be taken into account since it could affect the accuracy of knowledge.
