Sensing vs intuition: S and N explained by a coffee order

Ask two people to describe a coffee they liked.

The first one says it was a flat white, whole milk, from the place on the corner near the station, and it was not too hot, which is the part most places get wrong. You could go and buy that coffee this afternoon.

The second one says it tasted like a Sunday. Pressed for detail, they say it was the kind of coffee you have when you have nowhere to be, and then they start talking about a trip they took in 2019, which is not about coffee at all and is clearly connected in their head.

Both of them enjoyed a coffee. They came away with different things, and what each one came away with is the second letter of a four-letter type.

The difference is what gets noticed first

S and N are about which kind of information arrives first and feels most solid.

Toward the S end, what arrives first is the thing itself. Temperature, price, the actual taste, the fact that the queue moves faster on the left. It is specific, it is checkable, and it is available now. A person working from that material tends to build outward from what is in front of them, and to treat a claim as real once it has been seen.

Toward the N end, what arrives first is what the thing connects to. This coffee is like that coffee, this Sunday is like that Sunday, this shop has clearly been designed by somebody who has seen the shop in the other city. The information is relational: the pattern registers before the detail does, and often instead of it. Ask an N what the cafe looked like and there is a decent chance they cannot tell you, having spent the whole visit somewhere else.

Neither of these is a decision about what to value. It is closer to the order in which things show up, and the order is difficult to change on purpose.

Two descriptions that both get it wrong

This pair attracts worse explanations than the other three, and two in particular are worth clearing out of the way.

The first is that S means practical and N means creative. That flatters one side and insults the other, and it does not survive contact with anybody. Building something that works, on a Saturday, from parts you have, is a creative act performed almost entirely with concrete information. And plenty of pattern-first people are hopeless at producing anything at all, since a pattern is not a product.

The second is that S means literal and N means imaginative. Sensing is not a failure to get a metaphor. It is a preference for the version of a statement that can be checked, which is a completely different thing and is often the reason a project ships. The N who says the whole department is basically a submarine is not being deep. They are compressing, and it is a real form of information that occasionally turns out to be exactly right and occasionally turns out to be a submarine.

Directions, instructions and the same argument every time

The clearest everyday demonstration is asking someone how to get somewhere.

One kind of answer is a sequence: left at the lights, past the pharmacy, second right, it is the blue door. Each step is checkable while you are standing in front of it, and the instructions fail completely if the pharmacy has closed down.

The other kind is a shape: it is on the far side of the park, roughly behind the big church, if you end up at the river you have gone too far. There is no sequence to follow, and it is close to useless to somebody who wanted turns, but it is robust to the pharmacy closing and it lets you recover from a wrong turn on your own.

The same split runs through instructions at work. One person writes down the steps. The other explains what the thing is for and expects the steps to be obvious from there. Each finds the other's version irritating: one is a wall of detail with no point visible, the other is a point with no way to act on it. Almost every complaint about bad documentation is one of these two people reading the other one's work.

How each side gets it wrong

Sensing goes wrong by trusting the sample. What is in front of you is real, and it is also one instance. Three quiet weeks in a shop is a fact about three weeks, and reading it as a fact about the business is how a slow decline gets noticed a year late.

Intuition goes wrong by trusting the pattern. Once a shape has been recognized it is remarkably hard to unsee, and the details that do not fit get quietly filed as noise. This is the person who has the whole situation worked out on Tuesday and turns out to have been confidently wrong since Tuesday, because nobody checked the one number that would have settled it.

The failure modes are symmetrical, which is why a team with both is better than a team with either. It is also why the pairing is a common source of friction in group projects: the ideas and the constraints arrive from different people, and the ideas sound more impressive in a meeting.

Why this letter is the hardest to score yourself on

Ask someone whether they prefer facts or possibilities and nearly everyone chooses both, honestly. That is a real problem with self-report on this pair, and it is why this middle letter is the one people most often get back differently on a second attempt.

A better question is what you do when you are stuck. Facing a decision you cannot resolve, do you go and get more information about the specific case, or do you go and look for a comparable case that already got resolved? Both are sensible. Which one you reach for without deciding to is the letter.

Another useful test is what you remember about a conversation a week later. The exact thing somebody said, or what you concluded from it. Most people are strongly one or the other and have never noticed it, because there is no occasion on which anybody compares. The test itself asks a version of this several times, and why results change between attempts covers what a near-even middle letter actually means.

What the letter does not say

It says nothing about intelligence, imagination or how good anybody is at their job. It also is not a fixed quantity: the same person is far more concrete in a domain they know well and far more pattern-driven in one they do not, which is why a chef and an analyst can be the same type and look nothing alike at work.

MBTI is a trademark of The Myers-Briggs Company. This site is not connected to them, and I am not a psychologist; four letters are a description of a preference, not a measurement of a mind.

The version worth keeping is the one at the counter. Two people, one drink each, both perfectly happy, and two completely different accounts of what happened. Neither of them is failing to notice. They are noticing different things, and most of the time that is a good arrangement rather than a problem to be solved.
