Which is not one of the four attitude-change strategies mentioned?

The strategy of making an existing unfavorable belief more favorable is not typically recognized as one of the four primary attitude-change strategies. The four strategies generally focus on enhancing or modifying beliefs in a constructive manner, rather than altering the fundamental nature of a negative belief directly.

Adding a new salient belief about the attitude object provides additional information that can positively shift attitudes. Increasing the strength of an existing positive belief reinforces an already favorable perception, making it more impactful in influencing behavior. Improving the evaluation of a strongly held belief focuses on enhancing the positive attributes associated with beliefs that are already embraced by an individual.

In contrast, simply making a negative belief more favorable doesn’t align with the broader strategies of attitude change that aim to strengthen positive associations or integrate new, beneficial information. Instead, it emphasizes a direct alteration of negativity without a constructive foundation, which may not lead to effective attitude change.
