16-Type Personality Test

A 16-type personality test sorts your preferences into four pairs and combines them into one of sixteen four-letter types. It is the most familiar personality shorthand there is: people put their four letters in their bios and argue about them over dinner.

Ours is our own proprietary questionnaire. You see two statements at a time, such as "I think out loud" and "I think before I speak", and pick the side that sounds more like you. Forty pairs, ten for each letter, and no right answers.

What you get is your type, a short portrait of it, and four spectrum bars that show exactly where you landed on each pair.

Each letter is one side of a pair of preferences. Together they describe where you get energy, what you notice, how you decide and how you like to live.

• E or I, Extraversion or Introversion: do you recharge with people or on your own? E types want to go out after a long week. I types want a quiet weekend.
• S or N, Sensing or Intuition: do you trust what you can see and measure, or your hunches about what it all means? S types notice details. N types notice patterns.
• T or F, Thinking or Feeling: when you decide, do you weigh the argument or the people affected? T types would rather be honest even if it stings. F types would rather be tactful.
• J or P, Judging or Perceiving: do you like things settled or open? J types live by to-do lists. P types do their best work close to the deadline.

None of the letters is better than its partner. Each one is a preference, and preferences are where you are most at ease, not the limit of what you can do.

Here is every type in a line, so you can find yours and the people you know.

• INTJ: a private plan, held to a high standard.
• INTP: a mind that will not leave a puzzle alone.
• ENTJ: you will organise the room, including the bits nobody claimed.
• ENTP: you argue for sport, and you often improve the idea.
• INFJ: you see the pattern in people, and you take it seriously.
• INFP: values first, and a private weather system.
• ENFJ: you make sure the group becomes a group.
• ENFP: possibilities, said out loud, with feeling.
• ISTJ: if you said you would, it gets done.
• ISFJ: you remember the practical thing that makes someone comfortable.
• ESTJ: a clear job, a clear owner, a clear done.
• ESFJ: you host the actual day, not the idea of it.
• ISTP: you would like to take it apart and put it back better.
• ISFP: a personal standard, kept off the stage.
• ESTP: you read the room at full speed.
• ESFP: you make the ordinary hour feel like an occasion.

Each type has its own page that goes further into work, relationships and the kind of problems it enjoys.

We use our own proprietary structure: forty paired statements, scored as four spectrums. Each pair of letters gets a score from 0 to 100 based on which side you picked across its ten pairs. Below 50 gives you the first letter, 50 or above gives you the second.

Most tests stop there. We go one step further. If any of your four scores lands between 40 and 60, your result marks it as close to the line and shows you both possible types. Someone who scores 52 on E or I is not the same as someone who scores 95, and your result tells you which one you are.

If you are between two types, read both and keep the one that sounds more like you on an ordinary Tuesday. Being close to the line on a pair means you use both sides comfortably, which is a strength in its own right.

A close J and P, for example, often shows up as someone who plans the big things and improvises the small ones. A close T and F tends to be the person who can deliver hard news kindly. Look at which letter flipped, read the two descriptions side by side, and notice which sentences make you nod.

It also helps to ask someone who knows you well. Friends often see your letters more clearly than you do, especially on the pairs where you think you ought to be one way and quietly live the other.

Use your type as a shortcut for conversations you would otherwise struggle to start. Telling a colleague you are an I who thinks best after the meeting, not during it, is easier than explaining it from scratch.

Use it at work, too. An ISTJ who knows they need the plan in writing can ask for it up front instead of quietly fretting. An ENFP who knows they lose interest once a project turns routine can volunteer for the launch and hand over the maintenance. A team that knows its mix of letters can split the work by what each person enjoys, and stop treating different habits as bad habits.

Compare types with a partner or friend. Differences on the last two letters cause the most everyday friction: one of you wants the holiday booked in March, the other wants to see what the weather does. Naming it turns an argument into a joke you both understand.

Then go deeper. If you want to see how strongly you lean on each trait, the Big Five gives you a finer reading on five separate dials.
