I have read that INFPs are rather rare, in only about 4% of the population.
However, out of the five people in my family, three tested as INFP and agree the profile fits. A few extended family members tested as /seem to be INFP as well. I suspect a few others are INFP. If they are so rare, how come so many showed up in a small group of people? How rare are INFPs really? Or is personality genetic and that's why it shows up in my family? How many other INFPs do you know?
