When comparing INFPs (Introverted, Intuitive, Feeling, Perceiving) and ISFPs (Introverted, Sensing, Feeling, Perceiving) in terms of being easily influenced, it's essential to consider that personality traits and behaviors can vary significantly within individuals, and not all INFPs or ISFPs will fit a specific stereotype. However, based on their cognitive functions and typical characteristics, we can explore some general tendencies.
INFPs: INFPs are often described as idealistic, sensitive, and deeply empathetic individuals. They have a dominant function of Introverted Feeling (Fi), which means they place a high value on their inner values, morals, and emotions. They are guided by their strong internal principles, which they use to make decisions and judgments about the world around them. Because of this, INFPs can be relatively resistant to external influence if it contradicts their deeply held beliefs and values.
However, INFPs also have an auxiliary function of Extraverted Intuition (Ne), which makes them open to exploring new ideas and possibilities. While they may be firm in their core values, they can be influenced by innovative and inspiring concepts that align with their personal values and aspirations. They may be more receptive to new perspectives if they feel that these ideas resonate with their sense of identity and inner compass.
ISFPs: ISFPs are known for being artistic, observant, and emotionally in tune with their surroundings. Their dominant function is Introverted Feeling (Fi), much like the INFPs, which means they also have a strong inner value system. They prioritize authenticity and sincerity in their actions and choices, often guided by their feelings and personal beliefs.
The auxiliary function of ISFPs is Extraverted Sensing (Se), which makes them highly attuned to their immediate environment and sensory experiences. While ISFPs can be influenced by their immediate surroundings and the people they interact with, they are more likely to be swayed by concrete experiences rather than abstract ideas or theoretical concepts.
Conclusion: Both INFPs and ISFPs have strong internal values and principles due to their dominant Introverted Feeling (Fi) function. This can make them relatively resistant to influence when it comes to matters that deeply affect their personal beliefs and values. However, the extent to which they are influenced by external factors can also depend on their secondary functions (Ne for INFPs and Se for ISFPs) and their individual life experiences.
Ultimately, the susceptibility to influence varies from person to person, and it is essential to remember that each individual's personality is a unique combination of traits and experiences.
