Public opinion toward asylum seekers within Australia has become increasingly hostile over the past decade. In particular, such negative attitudes are associated with questioning the legitimacy of those who seek asylum, and the fairness of granting their refugee status. In a sample of 100 students (M age =22.83 years, SD age =8.26 years) we tested the role of macro and micro principles of social justice in predicting attitudes toward asylum seekers, beyond the established role of social dominance orientation (SDO) and right-wing authoritarianism. Using multiple hierarchical regression analyses, we show that macro justice social principles (i.e., the belief in equal distribution of resources across a society) predict positive attitudes toward asylum seekers beyond the variation accounted for by SDO and RWA in predicting negative attitudes. These results underscore the importance of taking into account individual orientations toward justice; we argue that these findings have important implications for the development of communication designed to reduce prejudice toward asylum seekers.

Childhood vaccination is widely considered to be one of the most successful public health interventions. Yet, the effective delivery of vaccination depends upon public willingness to vaccinate. Recently, many countries have faced problems with vaccine hesitancy, where a growing number of parents perceive vaccination to be unsafe or unnecessary, leading some to delay or refuse vaccines for their children. Effective intervention strategies for countering this problem are currently sorely lacking, however. Here, we propose that this may be because existing strategies are grounded more in intuition than insights from psychology. Consequently, such strategies are sometimes at variance with basic psychological principles and assumptions. By going against the grain of cognition, such strategies potentially run the risk of undermining persuasive efforts to reduce vaccine hesitancy. We demonstrate this by drawing on key insights from cognitive and social psychology to show how various known features of human psychology can lead many intuitively appealing intervention strategies to backfire, yielding unintended and undesirable repercussions. We conclude with a summary of potential avenues of investigation that may be more effective in addressing vaccine hesitancy. Our key message is that intervention strategies must be crafted that go with the grain of cognition by incorporating key insights from the psychological sciences.
