Final answer:
The headline 'Scott Howard is the Best Candidate for Mayor' shows media bias because it expresses a subjective opinion rather than neutral reporting. Media bias can manifest in different ways, including the placement of stories, the selection of biased sources, and the slant in framing of the issues.
Step-by-step explanation:
The headline that exemplifies media bias is "Scott Howard is the Best Candidate for Mayor." This statement is an example of media bias because it contains a subjective judgment rather than presenting impartial information. In contrast, the other headlines simply state that the individuals are supporting an issue or receiving contributions, without explicitly endorsing or criticizing them.
Types of media bias can include biases by placement, selection of sources, or the framing of stories. Bias by placement occurs when a media outlet consistently presents one political perspective more favorably or prominently than another. The selection of sources bias is evident when news stories disproportionately feature experts or quotations that support a particular perspective.
The framing of stories refers to how media outlets might portray news events in a light that aligns with their editorial stance, sometimes highlighting certain aspects while omitting others. All these biases can affect public opinion and the outcome of elections, as they can shape the way issues and candidates are perceived.
