Could it happen to you? Predicting the impact of downward comparisons on the self.

Three studies examined the impact of downward comparisons on the self. Worse-off others exerted an impact only when participants drew an analogy between themselves and the other. When participants did draw an analogy, the impact of the other on the self was determined by perceived vulnerability to the other's negative fate. When vulnerability was low, downward comparisons enhanced self-evaluations. When vulnerability was high, downward comparisons deflated self-evaluations, but activated a prevention orientation, boosting motivation aimed at avoiding the negative experience of the other.
