A Sigma INFJ refers to a specific personality type within the Myers-Briggs Type Indicator (MBTI) framework. To understand what a Sigma INFJ is, let's break down each component:

1. INFJ: INFJ is one of the sixteen personality types identified by the MBTI. It stands for Introverted, Intuitive, Feeling, and Judging. INFJs are known for their unique combination of traits. They are introverted, meaning they gain energy from spending time alone and tend to be reflective and introspective. They are intuitive, relying on their gut feelings and insights to understand the world around them. They are feeling-oriented, making decisions based on their values and emotions. Lastly, they are judging, which means they prefer structure and organization and tend to be decisive.

2. Sigma: The term "Sigma" is not an official part of the MBTI framework but is often used in online communities to describe a specific subset of INFJs. Sigmas are individuals who possess a combination of introverted and independent traits. They are often seen as loners or outsiders who prefer to operate on the fringes of social groups rather than being part of the mainstream. Sigmas tend to be self-reliant, self-sufficient, and value their freedom and autonomy.

When we combine these two terms, a Sigma INFJ can be described as an INFJ personality type with additional characteristics of independence, self-reliance, and a preference for solitude. Sigma INFJs often possess a strong sense of individuality and tend to be more comfortable working alone or in small, intimate settings rather than large social gatherings. They may have a unique perspective on life and may not conform to societal norms or expectations.

It's important to note that the concept of Sigma INFJ is not universally recognized or accepted within the MBTI community. It is more of an informal label used by some individuals to describe a specific manifestation of the INFJ personality type. As with any personality typing system, it's essential to remember that individuals are complex and unique, and not all INFJs will fit neatly into the Sigma category.
