This might change your Monday mood. For a while. In a recent study entitled Memories of “Bad” Days Are More Biased Than Memories of “Good” Days: Past Saturdays Vary, But Past Mondays Are Always Blue published by Charles Areni and Mitchell Burger of the University of Sydney, it was found that, on average, people’s moods remained about the same throughout the week. Mondays were not as depressing as people thought and Fridays and Saturdays were not as exciting as people predicted. The results, according to the study, demonstrate the memory bias: when thinking back, we tend to recall the worst incidence of an event we’ve experienced before. Mondays are stereotypically depressing, so we tend to recall the worst Mondays. Fridays and Saturdays are stereotypically exciting so we tend to recall the best Fridays and Saturdays. Consequently, in reality our mood fluctuation over the week might not follow the stereotypical pattern of a steady increase from a low on Monday to a high on Saturday. Instead our weekly average mood profile could be much flatter than we imagine, according to the study.
