Hello there!
If you’re an INFJ reading this, there’s a good chance you already have a few INFJs in your little circle of friends and acquaintances. We (INFJs) tend to have some sort of attraction field that pulls like-minded beings (other INFJs) toward us. To back up my claim, I conducted a survey on Facebook. I posted a link to this free personality test. My response pool was strictly limited to my friend list. 226 people responded (so far). Here are the results:
The obvious inference is that 39 (17.3%) of my friends & acquaintances (out of 226) are INFJ, nearly 6 times the world average! The other less obvious inference is I happen to attract the iNtuiting types (_N__), and keep away from the Sensing types (_S__), for some reason, comparing with the average.
There are a couple of INFJ-specific forums, but you never know if the person you meet is actually INFJ, a mistype or just there because of the hype. (That rhymed!)
Personally, I have never frequented these forums because I don’t believe in restricting my online interactions to people who only think and behave like I do.
Out of the 16 Myers-Briggs personality types, INFJ type is believed to be the most rare. These uncommon jewels of the personality spectrum make up less than one percent of the world’s population. (Source: The World’s Rarest Personality: INFJ Type Decoded)
So, obviously, assuming half the INFJs are males, we do qualify as “rare“, don’t we? I do, however, know at least 4 INFJ males, excluding me. That makes 5 of us.
INFJs are rare, yes, but certainly not “on the verge of extinction“. There are at least over an estimated 110 million of us walking around on this planet at this very moment. You know what’s actually on the verge of extinction? The Northern White Rhinoceros. There are only 4 of them left in the world today, as of January 2016.
