10 Signs You’re An ISFP – One Of The RAREST Personality Types In The World

The Myers-Briggs Type Indicator (MBTI) is one of the most widely used personality assessment tools, utilized by over 2 million people annually. Developed in the 1940s by mother-daughter duo Isabel Myers and Katharine Briggs, the MBTI categorizes individuals into 16 distinct personality types based on traits, tendencies, and preferences. The system is grounded in Carl Jung’s theory of psychological types. Jung posited that variations in how people perceive the world and make decisions derive from innate predispositions.

The MBTI identifies these inclinations by evaluating personality across four dichotomies – Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. Different combinations of these preferences result in 16 distinct types. Each type has its unique strengths, weaknesses, and characteristics attributed to it. For example, the ESTJ “Executive” type is driven and organized, while the INFP “Mediator” type is imaginative and empathic. Knowing one’s type provides insight into career selection, relationships, personal growth, and more.

One of the more prevalent MBTI types is the ISFJ, making up an estimated 13% of the population. Referred to as “Defenders,” ISFJs are categorized by their selfless service, excellent memories, and love of tradition and security. However, they may struggle with abstract concepts, conflict, and adapting to change. Learning about the ISFJ type offers this group greater self-awareness to optimize their natural gifts while developing lesser strengths.

Some essential qualities and preferences that typify the ISFJ include:
