The condition of having gotten most or all information on one or more topics from one or more sources which share a deliberate bias, leading to simplistic, biased grasps of those topics and an unwillingness to consider other views.
Everyone has their own inherent biases, so try to counter them by getting your news from a variety of sources, if you only listen to one side or the other, you'll end up so dysinformed that you can't carry on a rational discussion of anything.
