Which of the sixteen Myers-Briggs personality types are you? Take these two tests and post results. I usually get INFJ; my guess is that Hikaru-sensei would be either INFJ or ENFJ.

I remember taking one of these tests a really long time ago when I was in college, and I'm pretty sure that it was ENFJ. But I took the sakinorva test that you posted and got INFP. The "NF" was really strong on both parts so I think that is accurate. I also remember that they told us that people become more introverted as they age, so I may have gone that way over time. I'm not sure about the J/P change though. It could be test error, or maybe I've learned a few things over the years about making hasty decisions. ;;

slight I preference
strong N preference
strong F preference
slight P preference

That's interesting; do you think you were more extroverted in college than you are now? Curious about how much Hikaru-sensei has changed.
