We all know the distribution of types among the population.
My question is why....
Why are INFJ the most rare? From an evolutionary perspective or whatever.
Why are ISFJs so common among woman, nurturing instincts of course. It tells us that biology and gender do have an influence on the innate personality we are all born with.
Some types seem obvious why they occur more in a certain gender, but has anyone studied this?
Links are appreciated.
