Technically the 16personalities system is only based on the MBTI, and isn't technically the MBTI.
But either way, I always pick a MBTI type for my characters when I first create them, before I start RPing them, because it helps me keep their characterization consistent. If you're going into the MBTI (not 16personalities, but the actual MBTI) the real meat of it is the cognitive functions, of which each type has a distinct combination of four. Any generic description of the types is just a stereotypical description of how these four functions tend to manifest, but the cognitive functions are what really help you figure out what motivates a character and drives their actions. It's a little window into their actual thought process.
But since this thread links the 16personalities quiz, I actually did this the other day and made one of those "tag a bunch of tumblr people to do this too" posts on tumblr about it. :V
Shoshopu -  “THE CAMPAIGNERâ€Â (ENFP-T)
“The Campaigner personality is a true free spirit. They are often the life of the party, but unlike types in the Explorer Role group, Campaigners are less interested in the sheer excitement and pleasure of the moment than they are in enjoying the social and emotional connections they make with others.
They tend to see life as a big, complex puzzle where everything is connected – but unlike Analyst personality types, who tend to see that puzzle as a series of systemic machinations, Campaigners see it through a prism of emotion, compassion and mysticism, and are always looking for a deeper meaning.â€
Eaubront -  “THE ENTREPRENEURâ€Â (ESTP-A)
“Entrepreneurs always have an impact on their immediate surroundings – the best way to spot them at a party is to look for the whirling eddy of people flitting about them as they move from group to group. Laughing and entertaining with a blunt and earthy humor, Entrepreneur personalities love to be the center of attention. If an audience member is asked to come on stage, Entrepreneurs volunteer – or volunteer a shy friend.
Entrepreneurs are the likeliest personality type to make a lifestyle of risky behavior. They live in the moment and dive into the action – they are the eye of the storm. People with the Entrepreneur personality type enjoy drama, passion, and pleasure, not for emotional thrills, but because it’s so stimulating to their logical minds. They are forced to make critical decisions based on factual, immediate reality in a process of rapid-fire rational stimulus response.â€
Eaubront actually started life as an ENTP, but ESTP generally fits him quite a bit better. ENTP and ESTP similar in some ways, but their primary and inferior functions are swip-swapped, so they have a couple fundamental differences. I guess the way I'm RPing him has shifted over time. I always had a difficult time wrapping my head around the ENTP's objectivity when it comes to emotional situations, anyway. I'd be halfway through an emote and I'd catch myself thinking, "Wait, no, he wouldn't think to say that..."
