Ambivalent about who to vote for? You're more likely to be persuaded by a disreputable source

In the first study to propose a model for how information is processed by people with differing levels of ambivalence, researchers from Columbia University and Austral University in Argentina find that ambivalent people are more likely to be persuaded by disreputable sources. Those who are strong in their opinions are more likely to evaluate the reliability of the message's source before deciding whether to accept it.
