There isn't one single "most private" personality type, but INTPs (Logicians) and INTJs (Architects) are often cited due to their deep focus on internal logic, ideas, and strategies, valuing intellectual privacy and keeping personal plans to themselves.

But INFJs have a complex inner world, and they don't share this with people they don't trust. They're private, and they protect their value system with surprising intensity. They will withdraw from anyone who doesn't respect their values. INFJs are the rarest type of personality.
Introverts can also sometimes be considered loners. These are people who enjoy time alone, not necessarily because they don't like being around other people, but rather because they are more interested in their own inner thoughts and feelings. Spending quality time by themselves is how they are able to regain energy.

Key Takeaways. There are four types of introverts: social, anxious, thinking, and restrained introverts.
Part of what makes INFJs so guarded is their deeply private nature and their sensitivity to being misunderstood. They don't just want surface-level connection. Rather, they crave depth, resonance and emotional safety. And because they feel things so intensely, they often protect their hearts like precious artifacts.
Overthinking is a big problem for both INFJ personality types and INFP personality types. As a writing coach who specializes in working with both types, I've seen that overthinking is tied to INFJs and INFPs struggling overall with creativity, feeling connected to their intuition, and life in general.
