What describes a shift in attitude that opposes the intended message?

The Boomerang Effect describes a phenomenon where an attempt to persuade an audience with a particular message instead leads to an opposite response or attitude shift. This occurs when the audience not only rejects the intended message but may become more entrenched in their original viewpoint. An example of the Boomerang Effect could be a campaign aimed at reducing smoking that inadvertently causes some individuals to feel defensive about their smoking habits, leading them to smoke even more.

In contrast, the other choices represent different concepts that do not capture this specific dynamic of opposing an intended message. Neutralization might refer to processes that balance out differing viewpoints without significant opposition. Conservation typically involves maintaining existing benefits or practices rather than a direct attitude shift. Conversation generally involves dialogue and exchange of ideas, but it doesn't inherently imply a response that opposes an initial message.

Thus, the Boomerang Effect is distinct because it directly addresses this counterproductive response, highlighting how effective messaging can backfire.
