When it comes to the topic of advertising, one example of a bias thing that comes up fairly often would be the fact that it could either steer an audience to the direction the promoter wants (usually painted as positive/captivating), or it could steer the audience to a fairly negative direction. Let's take the example of beauty advertisements. A company is selling a beauty product and portraying beautiful individuals with an unrealistic expectation of the human physique. Even if it's not an "unrealistic expectation", what is the company really trying to sell? The product, or the idea that the product will make an individual more beautiful? and if so, what do those individuals look like, what is their structure/physique/attraction level? However, the bias relies solely on that. Either it could be a positive message as in "Hey! Come buy our product" in a totally innocent way or it could totally devastated an audience member thinking that they would never look good enough as into reaching that expectation... or both.
