By now, most of us have heard of the Myers-Briggs test — a highly popular quiz that files people into one of 16 personality types. And then there are the slews of other personality and compatibility quizzes online, geared towards trying to make life a bit more understandable and less chaotic. If you’ve been trying to categorize yourself and all your friends, you can forget about fill-in-the-blank quizzes. It turns out this new Tumblr page is all you need.

Called “2 Kinds of People,” the blog nicely divides all of humanity into two groups. The lovely person behind it is Joao Rocha, an art director from Lisbon, Portugal. She’s also the creator of Kim Jong-Il Looking at Things, which always inspires a giggle or two.

People aren’t that black and white, you say? We’re betting a few scrolls down this blog will convince you otherwise.

Which one is your favorite? Let us know below!
