Yes, I stayed up to take this test :)

...and here are the results, as delivered to me...

INFJ - the counselor
You scored 9% I to E, 15% N to S, 9% F to T, and 47% J to P!

Your type is best summed up by the word "counselor", which belongs to the larger group of idealists. Only 2% of the population share your type. You are so empathic that you often know what others need before they know themselves. You are a complex person who can deal with complicated issues and people, almost prefer to, as you love problem solving. You can be something of an idealist or perfectionist, and should try to take yourself a little less seriously.
You are a supportive and insightful romantic partner, encouraging your mate to have dreams and work hard to make those dreams come true. Because you are so creative, you have a wealth of ideas to help them toward those goals. You need harmony so much that you are driven to resolve conflict quickly, as long as the terms don't violate your ethics. You feel the most appreciated when your partner admires your creativity, trusts your inspirations, and respects your values. It is also vitally important that your partner be open and emotionally available - in other words, that they be willing to share themselves completely.
Your group summary: idealists (NF)
