It is important to be cautious when making broad generalizations about personality types and their origins. Stating that INFPs (Introverted, Intuitive, Feeling, Perceiving) and INFJs (Introverted, Intuitive, Feeling, Judging) are "created" by troublesome environments or problematic families is not accurate and can perpetuate stereotypes.
Personality types, as described by various personality frameworks like the Myers-Briggs Type Indicator (MBTI), are believed to be innate preferences that individuals are born with. These preferences are thought to influence how people perceive the world, process information, and make decisions. While life experiences and environments can shape individuals in various ways, it is not accurate to suggest that specific personality types are solely the result of problematic upbringings.
Furthermore, people of all personality types can be influenced by their environments, families, and life experiences. The way individuals respond to their environments can vary greatly due to the complexity of human behavior and the interaction between nature (innate tendencies) and nurture (environmental influences).
It's important to treat personality type theories, such as MBTI, as tools for understanding individual differences and preferences rather than definitive explanations of a person's entire identity. People are multi-faceted and unique, and their personalities are shaped by a combination of various factors. Making sweeping statements about specific personality types and their origins can oversimplify the complexities of human behavior and psychology.
