The least common Myers-Briggs Type Indicator (MBTI) type is INTJ, making up only 21% of the population. INTJs are known for their analytical minds and love of knowledge, and are often described as thinkers or idea people. They are confident in their course of action and are not afraid to take charge. They prioritize efficiency and are not afraid to make tough decisions.
On the other hand, the most common MBTI type is ISFJ, making up 43% of the population. ISFJs are known for their practical and organized approach to life, and their desire to help and support others. They are detail-oriented and prefer a structured routine. They are also known for being polite and courteous, making them well-liked by many.
It's important to note that these are general trends and that individual personalities can vary widely within each type. Additionally, the MBTI is just one tool for understanding personality and should not be used to make judgments about an individual's character or worth. It's important to approach personality assessments with intellectual curiosity and an open mind.
