That's the takeaway from the latest and greatest study in the Journal of Positive Psychology, which takes aim at a core tenet of Office Space philosophy: It finds no statistical evidence for worse moods on the first day of the work week.
Three psychologists poured over tons of Gallup data, where 340,000 American citizens were asked about their mood on various days of the week. They recalled whether, on the day prior, they felt "enjoyment," "happiness," "worry," or "sadness," among other emotions.
As expected people did tend to report happier emotions when recalling their mood on a Saturday or Sunday. And there was a bit of a TGIF effect, with moods ticking upwards on Friday.
What did not show up was anything that looked like a case of the Mondays. People felt pretty much the same on Monday as they did on Tuesday, Wednesday and Thursday:
Mood patterns were virtually identical for men and women. The mood gap looks to decline as people get older, largely due to a decline in negative moods during the weekend. Perhaps the most surprising result was from retirees: They also showed a spike in positive emotions during the weekend, even though it was not being followed by a work week afterwards.
