INTj is a possible type for the man.
(Does anyone but me think that it is a fascinating phenomenon that people generally agree on how INTjs look like (including body type), but when they try to type them by writing styles and content of posts the debate never ends?)
maybe it's because INTjs are so open ended with their knowledge? I can't see many INTjs seeing themselves as "definately" being 100% sure of being INTjs. They're always willing to add in knew knowledge and opinions into the equation
