社交媒体信任对重大突发公共卫生事件中公众网络谣言自治行为的影响

从社会心理学视角、以社交媒体信任为切入点,基于新冠肺炎疫情,考察公众在重大突发公共卫生事件中网络谣言自治行为的心理机制。采用问卷方法对963名成年居民进行调查。结果表明:(1)公众对官方社交媒体的信任既能直接促进公众的辟谣行为,也能通过增强公众对战胜疫情的信心产生间接影响;(2)公众对官方社交媒体的信任影响公众对自媒体的信任,但自媒体信任不能独立于官媒信任影响辟谣行为。因此,我国社交媒体存在着两个舆论场且官方舆论占主导地位,及时、有效的官方报道不仅能提高公众对战胜疫情的信心,也能促进公众网络谣言自治,进而实现网络谣言治理主体的多元化。     

Welfare and Self-Governance

Two ideas have dominated ethical thought since the time of Bentham and Kant. One is utilitarianism, the other is an idea of moral agency as self-governance. Utilitarianism says that morality must somehow subserve welfare, self-governance says that it must be graspable directly by individual moral insight. But these ideas seem to war with one another. Can we eliminate the apparent conflict by a careful review of what is plausible in the two ideas? In seeking an answer to this question I examine (1) the implications of welfarism, (2) the nature of moral obligation (3) the nature of our moral knowledge.
