When we talk about biases we talk about the tendency of people to be prejudiced or inclined towards information, ideas, people, and other phenomena. Everyone has biases whether we acknowledge it or not, and whether we like it or not.
Also, which is probably more important, the way a piece of information is presented could also reveal biases. In such cases, one could say that the “information is biased”. That could be best observed in pieces of propaganda materials, but also, if one is careful enough – in everyday news, as every news channel has an agenda. Therefore, the way they present (or choose not to present) information is biased.
