Which impact is lincoln most likely hoping to achieve with the above statement

In most advertisements we see today, the goal is to persuade us into purchasing or viewing a product. This means being truthful about a product or its contents no longer becomes a priority. One of the largest purposes of viewing media is to obtain information. When that information becomes biased, much like the information in ads, it is no longer helpful. A flawed piece of information, such as the effects of a weight loss product, supplement, or exercise machine, can be harming or even deadly. Researching where the advertisement comes from, what it is trying to tell you, as well as assessing its claims, can keep you from being miseducated.
