The implications of sleep for morality are only starting to be explored.Extending the ethics literature, we contend that because bringingmorality to conscious attention requires effort, a lack of sleep leads tolow moral awareness. We test this prediction with three studies. Alaboratory study with a manipulation of sleep across 90 participantsjudging a scenario for moral content indicates that a lack of sleep leads tolow moral awareness. An archival study of Google Trends data across6 years highlights a national dip in Web searches for moral topics (butnot other topics) on the Monday after the Spring time change, whichtends to deprive people of sleep. Finally, a diary study of 127 participantsindicates that (within participants) nights with a lack of sleep areassociated with low moral awareness the next day. Together, these threestudies suggest that a lack of sleep leaves people less morally aware,with important implications for the recognition of morality in others.
