I'm a 9w8, but I have strong relations to 4's, which is the most common Enneagram type for INFJ's.
But then again, I see A TON of 5 and a little 6 too. My Enneagram variation depends somewhat on what mood you catch me in
INFJs are usually 1, 4, 9, occasionally 5. Anyone can be a 6, so factor that in too.
Not necessarily, but people can pick up the stereotypical traits of being distrusting and quiet. People tend not to look into the details of being a 6, it's kind of overlooked.
I'm sorry if I came off like a know-it-all or something of that sort, it wasn't my intention=/
