How would a negative bias most likely enter into a radio report?

There are two main ways a negative bias could enter a radio report. First, the radio station could have a particular agenda that they want to advance and this could have an impact on the way they deliver information. A second option would be that the reporter himself has a certain inclination which is reflected in the way he delivers his report. It is important for us, as viewers, readers and listeners to always be critical of the information we receive through these sources.
