According to biology professor Christoph Randler, morning people are viewed more positively. Through surveying 367 college students, Randler found that “The problem is that those with the genetic gift of “morning-ness” tend to be more highly rewarded. Morning-ness is perceived as a sign of activity and zest, whereas evening-ness implies laziness and loafing.”
As the story discusses briefly, this seems to be a cultural issue. In certain arenas, traits associated with being “up and ready” in the morning are prized. Being peppy and ready to go in the morning can indicate a person is efficient and in control.
How about a study that examines perceptions of people who accomplish roughly the same amount of work but who are opposites in terms of being morning or evening people. Do people and/or institutions place a higher value on being ready to go in the morning even if the work gets done by the end of the day?
