We've all seen ads where politicians smear the name of their opposition, foretelling utter doom if the other guy wins. As distasteful and low and these ads may be, the facts show that these ads really work and that's why we're seeing evidence of this form of advertising popping up just about everywhere.
Implications - A new study claims that "attack ads can sway voters even when they're planning to support the other guy." This information certainly doesn't encourage political candidates to "play nice" with one another.
It is certainly an interesting concept when thought of in the context of the business world. Will the business who runs a smear campaign against their main competitor gain their competitor's consumer base?
