While individual experiences vary, MBTI types associated with Judging (J) and Sensing (S) functions, especially ISTJs, ESTJs, ESFJs, and ISFJs (Sentinels), tend to be more morning-oriented, valuing routine and structure; conversely, Perceivers (P) like INTPs, INFPs, and ENTPs often lean towards being night owls due to their flexible, idea-driven nature.
Psychologists who study morningness have found that early types often lean toward traits like planning and responsibility. It makes sense. A person who values order and predictability is more likely to guard a sleep routine and let bedtime stay mostly steady.
Logicians (INTP) (85%), the personality type most likely to agree that they are night owls, tend to take the image of focused dreaminess to the extreme – that is, they get so caught up in their thoughts and ideas that schedules and day-to-day details, like remembering to go to bed, frequently fall by the wayside.
A lark, early bird, morning person, or (in Scandinavian countries) an A-person, is a person who usually gets up early in the morning and goes to bed early in the evening. The term relates to the birds known as larks, which are known to sing before dawn.
Yes, both. MBTI P-types are often procrastinators, but it is not limited to them. And, it can be a habit one's falls into, or has to work their way out of. And, there are different motivations that can cause one to procrastinate. So, it isn't one simple personality trait, even though the result is the same.
ISFP. Easygoing, creative, spontaneous, and modest, ISFPs may be more likely than others to self-medicate with substances. One study compared personality traits among people struggling with addiction. The researchers found ISFP to be one of the most common MBTI types among those who also struggled with a mood disorder.
Translated to Myers-Briggs lingo, Introverts, Sensors, Thinkers and Perceivers appear to be more boredom prone, which we will further discuss shortly.
People who wake up at 5am are often very conscious of routine as well as sleep hygiene. This means that they are often well-rested, always wake up feeling great because of their consistent schedule, and are able to quickly get into a routine every day.
Some evidence suggests that high IQ is associated with later sleep patterns. However, it is unclear whether the relationship between IQ and later sleep is due to biological or social effects, such as the timing of working hours.
They say the early bird catches the worm in business. In fact, some of the world's most successful leaders are morning people, including Tim Cook (Apple CEO), Howard Shultz (Starbucks CEO), Richard Branson, and Michelle Obama.
INFP. These are caring, quiet children who can get lost because they do not advocate for their needs but do advocate for the needs of others. They can feel the pain of others intensely. They enjoy the fantasy world and creating things in a slightly unique way.
As shown in table 2, the most frequently occurring type for this sample is ENFP (15.2%), followed by INFP (10.5%). The least common types are ESTP (1.2%), ISFP (2.0%), and ESFJ (2.0%).
Reluctant to Open Up – INFJ personalities value honesty and authenticity, but they're also private. They may find it difficult to open up and be vulnerable about their struggles, not wanting to burden someone else with their issues.
But just because the early bird gets the worm doesn't mean that the night owl is left empty handed (empty beaked?). Studies show that night owls and those who wake up later actually are smarter and more creative than their early rising counterparts. They also have higher IQs according to The Independent.
The koala is the animal that sleeps approximately 90% of the day (20-22 hours), a necessity due to its low-energy eucalyptus diet requiring intensive digestion, making it the ultimate champion of sleep in the animal kingdom, followed closely by sloths and bats.
While there's no single "rarest," the Stomach (Prone) position is often cited as the least common, with only about 7-10% of adults preferring it, followed by the Starfish (back with arms up), which is also uncommon (around 5-7%), though it's a popular back-sleeping variation. Other less frequent, but notable, positions include the Log (side sleeper with straight limbs) and T-Rex arms (neurodivergent self-soothing).
No, an IQ of 97 is not considered dumb; it falls squarely in the average range (90-109), indicating typical cognitive abilities, though some tests might place it slightly below the exact midpoint of 100. An IQ score of 97 means you performed better than 42% of people, and due to the test's margin of error, your score could be anywhere from the high 80s to the mid-100s, still within normal intelligence.
Albert Einstein is said to have slept 10 hours per night, plus regular daytime naps. Other great achievers, inventors, and thinkers – such as Nikola Tesla, Thomas Jefferson, Thomas Edison, Winston Churchill, Leonardo da Vinci, and Sir Isaac Newton – are said to have slept between two and four hours per day.
It's no secret that a good night's sleep can make us feel more positive and less prone to stress and anxiety. For Gen Zers, going to bed at 9 p.m. is part of prioritizing their mental well-being. Sleep is also essential for brains to function at their best.
Research indicates that individuals who wake up before 7 a.m. tend to experience greater happiness and better health. Studies have found that early risers report higher levels of positive emotions, life satisfaction, and lower instances of depression and anxiety.
According to a report by the Organization for Economic Co-operation and Development (OECD), Colombian are the world's earliest risers. The alarm clock at many Colombian households goes off at four or five in the morning. But why do Colombians wake up so early?
ESFP: Quick to Blow Off Steam
Dynamic ESFPs let their passions and whims rule them, so it isn't too surprising they're reactive when it comes to anger. ESFPs are quick to react to anger and other emotions, even if they regret it later.
The Joker being an ENTP personality type, he possesses certain personality traits that align with this classification. One of the key traits for ENTPs is their dominant Extraverted Intuiting (Ne), which is one of the eight cognitive functions that individuals use to take in information.
MBTI types with introverted, intuitive, and thinking preferences—such as INTJ, INTP, and ISTJ—are often associated with autistic traits. These types often display analytical thinking, deep focus, and preference for structure.
