What INFJ looks like

Lighthouses tend to combine a quiet inner world with a strong sense of purpose. Your answers lean inward, idea-driven, heart-led and planned, a mix that often shows up as someone thoughtful, perceptive and principled. You may notice what people feel before they say it, and you probably care about doing work that means something. Many Lighthouses are private but deeply loyal, with a small circle and big ideals. You might hold yourself to standards that are hard to meet, and recharge time is not optional. At your best you see where a person or a group is trying to go, you help them get there with patience and insight, and you rarely ask for credit.

The four letters

I · Inward: Recharges with quiet, depth and a few close people. Thinks first, then speaks.
N · Big-picture: Drawn to ideas, patterns, meanings and what could be.

How INFJ compares

Often clicks with warm, open-minded people who give them space to recharge. Types that share the middle two letters (INFP, ENFJ and ENFP) often find conversation easy. ESTP flips all four letters, so you'd likely teach each other the most. For fun only; there's no compatibility score.
