Are these common? Do you INTJs here consider yourself top possess these traits? INTJs are traditionally probably the most serious type and I'll be honest, I'm not sure I've ever met one! If I have, they were probably too focused for me to notice. There's one kid I know who I think is INTJ but I'm not sure (I've never talked to him, just he's a quiet hardworking genius). Anyway, so how do you INTJs think your sense of humour is, and your relations with other people. Can you be fun?
