There's no single "sharpest" MBTI, but INTJs, INTPs, and ENTPs are often cited for high intelligence (logic, analysis, big-picture thinking). INFJs are known for high emotional and intellectual intelligence, making them insightful. Ultimately, different types excel at different kinds of "sharpness," with ISTPs being quick learners and fixers, and INTJ/INTP dominating abstract problem-solving.
We've loosely ranked these types based on how often they align with more traditional success metrics such as leadership, innovation, financial gain, and industry influence. Our list of the most successful personality types includes the ENTJ, ESTJ, INTJ, ISTJ, ENFJ, ESFJ, ENTP, and ISTP.
All intuition dominants (INTJ, INFJ, ENTP and ENFP) score very high on IQ scales. Rationals are likely to be more intelligent than guardians. Likewise, thinking dominants (INTP and, ENTJ) also score higher than average. The more intelligent you are, the more likely you are to be introverted.
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%).
For ENTPs, life is about exploring every possible answer and imagining what could be instead of settling for what is. This personality type really enjoys playing devil's advocate because they genuinely see value in every side of an argument.
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.
INTJ - The Mastermind. "Most Independent"
INTJs are strong individuals who seek new ways of looking at things. They are analytical problem-solvers, eager to improve systems and processes with their innovative ideas. They are insightful and enjoy coming to new understandings.
Many autistic people tend to be more introverted, detail-focused, and prefer structure and routine. For example, personality frameworks like the Myers-Briggs Type Indicator (MBTI) often associate autistic traits with types such as INTJ, INTP, and ISTJ, which value analytical thinking and deep focus.
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.
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.
Quick Thinkers – ENTP personalities have tremendously flexible minds and are able to shift from idea to idea with little effort, drawing on their accumulated knowledge to prove their points, or their opponents', as they see fit.
Snoop Dogg has publicly stated he has an IQ of 147, a score that falls into the "highly gifted" or "genius" category, much to his own surprise given his self-described average school performance (straight Cs). While this self-reported score suggests exceptional intellect, IQ tests measure specific cognitive abilities, and success in life and business (like Snoop Dogg's multifaceted career as a rapper, entrepreneur, and media personality) reflects a broader range of intelligence and skills.
Sixteen personality types: The most common types among gifted adolescents were INFP, INTP, ENFP, and ENTP, which constituted nearly 50% of the gifted sample compared with 19% of the normative group. The most common preference among gifted adolescents is intuition.
As Clinical Psychologists, they have the opportunity to unify these interests and use them to improve the mental health and lives of their clients. As a result, MBTI® test INFJs can often make excellent Clinical Psychologists.

1. INFJ (The Visionary Bookworm) INFJs are the ultimate book lovers. Known for their introspective and empathetic nature, they find solace in exploring deep, meaningful stories.
The MBTI functions and attitudes that most correlate with ADHD are the intuitive (N) function and perceptive (P) attitude. People who score high on these dimensions have more chances of portraying ADHD symptoms.
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.
INFP — The Unrealistic Present Focused Idealist
The INFP is known as the fantastical idealist, and for good reason. We prefer our vivid dreams and fantasies to reality most of the time, and reality doesn't even come close to all the things we can imagine in our minds.
The notion that Intuitive Introverts—INFJ, INFP, INTJ and INTP types—tend to be more Neurotic squares with common perceptions of these types, as well as the highly sensitive person (HSP) construct, which shares a number of overlaps with Neuroticism.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
Donald Triplett, autism's 'Case 1,' dies at 89. Triplett gained media attention for his autism later in life, and he became the face of the effort to research the lives of older adults with autism.
The Joker is usually an ENTP but that rendition was an INFP .
