>The researchers did not find any important differences between the results of the ANT test the early birds and night owls completed in the morning So the morning people are just as bad as a night person in the morning, and worse at night. Maybe they should revise the headline: Why you shouldn't hire morning people. >Participants were required to stay awake for 18 hours, from 8:00 a.m. to 2:00 a.m., and adhere to their normal routine. That doesn't seem to fit the normal routine of either a night person or a morning person, nor really the opposite. A morning person would be up earlier and asleep later, while the opposite for a night person. Seems a better test would be to have night people stay awake from 0500 to 2300 and morning people stay awake from 1100 to 0500 or something like that and test under those conditions that oppose their natural schedule. It gets worse: >>During the week prior to the SWP, participants were required to adhere to their normal routine as much as possible; e.g. have a normal sleep duration (approximately 7.5–8.5 h per day) and maintain regular sleep schedule (e.g. approximate bed time of 11:30 pm ± 60 min, and waking up at approximately 7:30 am ± 60 min each night/morning). So they forced night people to live on morning people's schedules, but not the other way around. (And yet the night people still performed better!) And the study was only done for one single day, which doesn't seem likely to have any bearing on how people actually perform over a sustained period of time (such as a regular job), but just how they might perform on an occasional holiday like New Year's Eve. Combined with such a small sample size, this study doesn't really seem to indicate much of anything except that the researchers could potentially have done a better study.
