This is a discussion on I have a theory: INFPs are less common than INFJs, INTPs are less common than INTJs within the Myers Briggs Forum forums, part of the Personality Type Forums category; Originally Posted by zoboomafoo INXPs that haven't found internal harmony, aka the 'perfect system', will look like they are living ...
Nah I think there a lot of people who think they are INFJs or INTJs when they're actually just organized, conscientious INFPs or INTPs.
Back to the INP's are rarer than INJ's thing...
You use the statement that the quantity of ISFJ's in the world is greater than ISFP's to imply something very different - that all P's are less common than all J's. This is problematic obviously because INFP's aren't ISFP's. And ISFJ's aren't INFJ's. There are 6 other J types that could comprise the bulk of the population and mean your sociology fits. It isn't a convincing way to argue INFP's/INTP's ought to be less common than the INJ counterparts.
Also, so If you think the most accurate attempts at self-typing are unreliable... and that behaviour is not a good indicator so no external judge could type any better. Why should we believe you when you say the quantity of ISFJ's>ISFP's is undisputed even when you also say any attempt to type is unreliable?
From my observation, the frequency of J and P are about evenly split in the general population.
When it comes to INXJ, the dominant function is Ni and this function is one of the rarest functions IMO. It's not easy to come across INFJs and INTJs in real life. INTPs, though not Ni dom, are also rather infrequent due to the INTX combination which is rather rare. Of the four INXX types, INFPs, with Fi as dom, will probably be the more common type especially among females.
I'm not sure what's the appeal of being a rare type though. Does that make one feel more special in some way or what? Don't forget that being a rare type means that it's much harder to form connections with others due to being different.
From my own experience, I've found that very few actual INFJs ever get their test results back as INFJ. Usually they consider themselves to be INTJs.
That's one of the flaws of personality tests: People have no intellectual honesty about themselves.
But as far as INFPs are concerned, I think a lot of studies show that more people are found to be INFP than INFJ. A quick internet search should provide a quick answer to your question.
