INTJ vs INFJ — Logic-Driven Vision vs Insight-Driven Vision

INTJs and INFJs are often confused. Both are quiet, intuitive, and future-oriented. But core motivations differ:

INTJ = analytical strategist
INFJ = empathetic counselor

This comparison explores how these two visionary minds differ in thinking, emotion, communication, and relationships.

1. Core Cognitive Difference

• Efficient planning — Optimized execution
• Strategic vision — Long-term goals

INFJ = Ni + Fe

INFJs use:

• Ni (Introverted Intuition) — Deep insight
• Fe (Extraverted Feeling) — Emotional harmony

Simple version:

INTJ = "What system will work most efficiently?"
