You’re Not A ‘Morning Lark’ Or A ‘Night Owl’ — Here’s The Test That Reveals Your Real Chronotype, By A Psychologist

Forget everything you thought you knew about being a morning lark or night owl. A psychologist says your body clock actually runs on three separate dials, not one, and a new science-based chronotype test can reveal your true rhythm.

In a Forbes article published July 18, 2026, psychologist Mark Travers introduced a quick, data-driven chronotype test that challenges the binary classification of sleep personalities. According to Travers, the traditional morning lark versus night owl model oversimplifies a complex biological system. The test evaluates three distinct aspects of circadian rhythm—sleep propensity, peak alertness periods, and energy dip patterns—to give a more precise chronotype profile.

For decades, people have labeled themselves as early birds or night owls, often adapting their work and social lives to a one-size-fits-all schedule. But research shows that forcing a mismatch between internal body clocks and external demands can harm sleep quality, productivity, and mental health. Travers argues that understanding your actual chronotype—not the one you assume based on habit—can unlock better daily performance.

The chronotype test described in the article asks respondents to reflect on their natural inclinations across different times of day, focusing on when they feel most alert, when they experience slumps, and how easily they shift their sleep times. The test is designed to be completed in under five minutes and is rooted in peer-reviewed circadian science. Travers emphasizes that many people who think they are night owls may actually fall into a middle chronotype or have a misaligned perception due to social jetlag.

Analysis of this development suggests the three-dial model aligns with growing evidence that circadian rhythms are multi-dimensional. Conventional chronotype quizzes often ask a single question about preferred wake time, missing nuance. By considering multiple factors, Travers's approach could help individuals fine-tune their schedules for peak cognitive work, exercise, and rest.

Looking ahead, personalized chronotype tests like this one could become standard tools in productivity coaching, workplace wellness programs, and even education. As wearable technology continues to track sleep patterns, combining such subjective tests with objective data may offer even deeper insights. For now, Travers encourages everyone to take the quick chronotype test and find out if they have been miscategorizing themselves for years.
