How to rate and roast your friend group with TikTok’s viral MBTI friendship compatibility test

This MBTI friendship group compatibility test has gone viral on TikTok. The test analyses the Myers-Briggs Type Indicator (MBTI) personality type of everyone in your friend group, and rates how disastrous all the friendships are.

Here’s an easy-to-follow guide to how to test your group’s compatibility, and an overly detailed explanation of how it actually works.

What even are MBTI personality types?

It’s star signs for people with LinkedIn accounts. Basically, a teacher called Katharine Briggs and her daughter Isabel Briggs Myers came up with the Myers-Briggs Type Indicator after a deep dive into Carl Jung’s book Psychological Types. There are 16 different personality types. The name of each type is made up of four letters, each representing a different trait. I is for introverted, E is for extroverted, N is for intuition, S is for sensing, P is for perceiving, and J is for judging.

Ta-da!

Even if you didn’t have a weird obsession with this when you were 18 (ahem, not me), you probably have taken a few MBTI tests without realising it – loads and loads of painful careers tests use it. Psychologists have very, shall we say, mixed opinions on the scientific basis of MBTI. But TikTok girlies and scary businessmen alike all swear by it.

How do you use MBTI to rate your friendship group’s chemistry?

If you don’t already know the MBTI of you and your friends, you’ll want to get on that first. This is the official MBTI test. A lot of people also like the quiz on 16 Personalities because the pictures are fun. Lots of the questions on online tests are a bit skewed towards certain traits, so you might be better off reading through the descriptions of each type and figuring out which you are by yourself.

When you’re mentally prepared to take the MBTI friendship compatibility test, visit this website. I shall be demonstrating with the friends from Friends.

Start by entering in your own MBTI (or, in this case, Phoebe Buffay’s).

I began with Phoebe because she is my spirit animal

Click, “save and see how we hit it off.”

The website then takes you to a complicated-looking diagram.

Hey Siri, play the Friends theme song

You can invite your friends to add themselves by sharing the link at the bottom. Or, you can add people’s personality types yourself.

You have to scroll down to the end for this

Once you’ve added the whole gang, click each friend to see how compatible they are with everyone else. There are five different ratings – perfect, good, ok, not bad and disaster. You have my condolences if this website thinks you and your bestie are a disaster.

Guess Ross and Joey should have had more screen time together

I actually think Rachel is an ESFJ until Season Five but Reddit thinks she’s an ESFP and I don’t want to anger them

You can also click on the result scale at the bottom to see all the friendships of a particular rating at once. So, you can see straight away who the disastrous friendship pairings are, and who’s guaranteed to cause chaos at your next pub night.

Errr, this website is a Roschel shipper?

My main conclusion is that Phoebe is right to worry she lifts right out of the friend group, because this friendship chemistry test thinks everyone secretly hates her. And apparently Ross and Rachel are each other’s lobsters after all?

What is this MBTI compatibility test based on?

Understanding the logic behind the MBTI friendship compatibility test requires extra in-depth knowledge of MBTI lore. Feel free to ask this website to rate your friendship group without knowing all the methodology. But if you have the mental capacity today, then here’s the detailed explanation.

Each of the 16 Myers Briggs personalities has four cognitive functions – introverted intuition (Ni) or extroverted intuition (Ne), introverted sensing (Si) or extroverted sensing (Se), introverted feeling (Fi) or extroverted feeling (Fe), and introverted thinking (Ti) or extroverted thinking (Te). A “function stack” is the set of functions which each person has.

You’re supposed to get on best with people whose cognitive functions complement your own. You with me still?

This makes much more sense with examples, I promise. So, Monica from Friends is an ESTJ. Her dominant cognitive function is extroverted thinking (Te). This means she gels the best with people whose dominant function is introverted thinking (Ti). Chandler is an INTP, so his dominant function is Ti. Ergo, Monica and Chandler are perfect for each other and Mondler is written in the stars.

On the other side, Phoebe is an ENFP, so her dominant function is extroverted intuition (Ne). She vibes the best with people who have the complimenting function, introverted intuition (Ni). It’s Chandler’s secondary cognitive function, which is why this website rates their friendship as “good”. But all the other friends are really low on it – Joey and Rachel have it at the very bottom of their function stacks, and Monica and Ross don’t have it at all. This is why the website savagely rates Phoebe’s friendships with these people as a “disaster”.

There you go! Get roasting your friendship groups with the MBTI friendship compatibility test, and start causing chaos in the group chat.
