The opposite of INFP in the Myers-Briggs Type Indicator (MBTI) is the ESTJ. INFP stands for Introverted, Intuitive, Feeling, and Perceiving, while ESTJ stands for Extraverted, Sensing, Thinking, and Judging.

1. Extraversion vs. Introversion: The most apparent difference between INFP and ESTJ is their preference for extraversion or introversion. INFPs are introverted individuals who tend to focus on their inner world, introspection, and personal reflection. On the other hand, ESTJs are extraverted individuals who thrive in social settings, enjoy interacting with others, and are energized by external stimuli.

2. Sensing vs. Intuition: INFPs rely more on intuition and abstract thinking, focusing on possibilities, patterns, and underlying meanings. They are imaginative and often seek deeper connections and meanings in their experiences. In contrast, ESTJs are more grounded in reality and rely on their senses to gather information. They are practical, detail-oriented, and prefer to focus on facts and concrete information.

3. Feeling vs. Thinking: INFPs are guided by their emotions and values, often prioritizing harmony, empathy, and personal values in decision-making. They are compassionate, empathetic, and considerate of others' feelings. Conversely, ESTJs are more logical and objective in their decision-making process. They prioritize efficiency, rationality, and fairness over personal emotions.

4. Perceiving vs. Judging: INFPs have a perceiving preference, which means they are more flexible, open-ended, and adaptable. They tend to be spontaneous, prefer to keep their options open, and enjoy exploring different possibilities. ESTJs, on the other hand, have a judging preference, which means they are more structured, organized, and decisive. They prefer to plan ahead, follow schedules, and make decisions promptly.

Overall, the opposite of an INFP, the ESTJ, is an extraverted, sensing, thinking, and judging individual who is practical, detail-oriented, logical, and prefers structure and organization. While INFPs are introspective, imaginative, empathetic, and value-driven, ESTJs are outgoing, practical, objective, and prefer efficiency and rationality.
