"Bad appeal to authority" seems like a fancy term for peer pressure. When you hear the phrase, “Come on, everyone is doing it,” it's a common "bad appeal to authority" case. We tend to believe in our friends because we can trust them. Although this really shouldn’t be the case because they may know what they’re talking about, but they could just be acting. People should keep in mind that unless there’s other evidence to show that what they are saying is true, you shouldn’t believe in it.
Actors and actresses on our favorite television shows and movies are perfect examples of this. We tend to believe in what they are doing is truly them because they are so confident in it. In reality, they’re just acting out a character. Most of the time, the character they are portraying is far from what they are in real life. It happens to me all the time. Whenever I watch GLEE, I always think that the actor playing Artie (a character who’s wheelchair bound) can’t walk. But after seeing dozens of interviews and seeing him in real life perform, I know he can walk. There’s no further proof to believe that he can’t walk, other than a tv show character. He's really convincing though...
