"Previous research has demonstrated that people have stereotypes of morning people and evening people. People tend to view morning individuals more favorably than evening individuals. The present study sought to observe whether people also discriminate against morning and evening people. One hundred fifty-six undergraduate students from Eastern Washington University were- asked to rate how likely they would be to choose to do certain activities with a morning person or an evening person. Participants were also given a self-report measure of their own circadian preference. Participants chose to do activities with morning people that aligned with the previous stereotypes of morning people. Participants also chose to do activities with evening people that aiigned with the previous stereotypes of evening people. Participants demonstrated an overall preference for people in their own circadian preference group as well. Overall this study supported the past literature on stereotypes of both morning and evening people as well as the tendency toward self-bias"--Document.
