A self-defeating prophecy can be the result of rebellion to the prediction. If the audience of a prediction has an interest in seeing it falsified, their actions upon hearing it will make the prediction less plausible. If a prediction is made with this outcome specifically in mind, it is commonly referred to as reverse psychology. Also, when working to make a premonition come true, one can inadvertently change the circumstances so much that the prophecy cannot come true.
It is important to distinguish a self-defeating prophecy from a self-fulfilling prophecy that predicts a negative outcome. If a prophecy of a negative outcome is made, and that negative outcome is achieved as a result of negative feedback, then it is a self-fulfilling prophecy. For example, if a group of people decide they will not be able to achieve a goal and stop working towards the goal as a result, their prophecy was self-fulfilling. Likewise, if a prediction of a negative outcome is made, but the outcome is positive because of positive feedback resulting from the rebellion, then that is a self-defeating prophecy.
