Two systems of thinking: why Kahneman's map fails marketers

The idea of System 1 and System 2 sounds clean: a fast intuitive brain and a slow deliberate one. A person is not built like a switch with two positions. Between “I felt” and “I thought” there is no border. There is a staircase, and a buyer climbs a dozen steps of it while you are still saying “they decided on emotion”.

Daniel Kahneman gave marketers a convenient language. System 1 works instantly and without effort: you recognise a friend’s face, sense that a banner looks cheap. System 2 switches on when you need to count, compare, weigh the terms of a contract. The scheme helped millions of people notice that most decisions are made somewhere other than the head. As a working map for someone who builds advertising and product, though, it is drawn at the wrong scale. It has two regions on it. You need streets and turns.

What is wrong with splitting the mind in two

When you say “the customer chose emotionally rather than rationally”, you are diagnosing “somewhere in the left half of the map”. True, and useless. Nothing follows from it except the usual line: push emotion harder.

The two-box split suggests a toggle: analysis on, feeling off. In practice both modes run at once and get in each other’s way. A buyer can know perfectly well that they do not need the subscription and still tap “pay”, because the button sits where the thumb has learned to expect it. Which is System 1 here and which is System 2? The question has no answer because it was asked wrong.

The second trap: the word “intuition” turns into a bin. Everything we failed to explain by reasoning gets tipped into it. A visitor left the site in two seconds: “it didn’t land on an intuitive level.” That is not an explanation. It is a confession that we do not know what broke.

The third problem is practical. A two-box scheme does not attach to money. You cannot write “we strengthened System 1” in a report and show what changed, so you cannot repeat a success either. If a video worked, you shrug: it landed emotionally. If it failed, same answer with a minus sign. A model that explains a win and a loss equally well explains nothing.

For a company selling into Russia from abroad this bites harder. Your Russian pages are reviewed by people who do not read Russian and rebuilt after every dip in conversion on the strength of “the audience is emotional here” or “Russians decide on trust”. Both are two-box labels. They travel well in meetings and point at nothing you can fix on Monday.

Not two floors but a staircase with gates

Picture a tall building with many floors rather than two. A signal from an ad, a price or a package enters at the bottom and climbs floor by floor. Each floor has its own door with its own lock. Some doors open easily. Others demand that the signal be stronger and clearer before they let it through.

Some signals are extinguished on the lower floors and never reach awareness. You saw a price set in an odd typeface, felt a flicker of discomfort and moved on, never noticing what pushed you away. Some reach the middle floors and produce a feeling: interest, unease, a small greed when “three left” sits next to the price. And some climb all the way up and become a conscious thought: “let me work out whether this pays for itself over a year.”

Between the floors stand gates. A gate is a threshold the signal must clear to go higher. If it fails, the signal stays on its floor and works silently there. This is why advertising can shape a choice while the person tells your survey, honestly, that it had no effect on them. It never rose to the floor where words live.

Using the ladder in advertising and product

The two-process model asks: was the decision emotional or rational? The multi-level model asks: on which floor did the decision ripen, which gates did the signal pass, and at which threshold did it get stuck?

A live example. Someone lands on your course page and leaves in five seconds without scrolling to the price. The two-system reading: emotion failed, make the copy grip harder. The multi-level reading: did the signal even reach emotion? Perhaps it stalled on the bottom floor, where the fast check “is this for people like me” runs. The first screen looked like an ad for large corporations, and the visitor owns a coffee shop. The “ours or foreign” gate slammed in a fraction of a second, and feelings never got a turn. The fix is the image and the first line that settle the question of belonging.

Another case. A customer reads the offer, nods, likes all of it, freezes on the payment button and closes the tab. Here the signal reached the top floor and calculation switched on. There it hit a specific threshold: unclear what happens after payment, whether money can be refunded, whether there will be another charge later. Emotion was for the purchase. The cure is one line about refunds next to the button, and no warmer picture will replace it.

Under the old scheme we would write “strengthen emotion” in both cases and be wrong in both. In the first, emotion was extinguished before it appeared. In the second, emotion was working and reason was applying the brake. The coarse map shows the two as identical.

So in my work I do not ask “rational or emotional”. I ask at which level a person gets stuck, and I place the signal there: in the ad, in the packaging, in the words on the button. Half of customer research is locating the floor on which the buyer accepts or rejects, rather than labelling the crowd.

One more subtlety the coarse scheme hides. A signal need not climb every floor in order. Sometimes reason says take it, but an old alarm has quietly fired below, and the hand does not move to the button. The person is not lying when they say “I like it, but something is off”. That “something” is a blocked signal on a floor their own words cannot reach. The job is to find that floor and lift the lock, rather than argue with the buyer in a language that lives nowhere near the jam.

Where the signal usually gets stuck

Over years of taking funnels apart, the same places keep turning up where gates slam.

The bottom floor, the “ours or foreign” check. In Russian the pair is свой или чужой, and it is settled in a fraction of a second by image, colour, first word. If the person did not recognise themselves, they go no further, and no argument placed above works. This is where paid search and targeted traffic most often dies: the ad brought the right person, and the first screen told them “you don’t belong here”. For a foreign company in Russia this gate is the expensive one. A page translated from English keeps its foreign faces, address format and payment logos, and each is a bottom-floor “not for you” fired before a sentence has been read. The visitor from Yandex does not think “this is a foreign company”, which would be a top-floor thought. They feel a mismatch and leave, and analytics records a bounce with no reason attached.

The middle floor, emotion and trust. The signal passed the belonging check but produced neither interest nor calm. The copy is correct and cold. What decides here is tone, detail, a living voice instead of bureaucratic phrasing. The person is not yet counting benefit. They are sensing whether it is safe here. In Russia the trust gate has a specific shape: a real person on the page, a phone number in a local format, a messenger where a human answers. A contact form alone passes this floor slowly, if at all.

The top floor, calculation. Only the warmed-up reach it. Here everything is spoiled by unspoken terms, hidden charges, vague timelines. The person wants to buy, caution switches on, and one unresolved objection outweighs ten arguments. For a company selling into Russia from outside, the top-floor questions are practical: how do I pay you at all given the card restrictions, what documents will I get, whom do I call if it goes wrong. A page that answers them is opening the last door.

Take any advertising path, from first impression to payment, and walk it step by step, watching where the customer falls off. Analytics gives you the numbers: how many left on the first screen, how many abandoned the cart. Your job is to translate the number into a floor and a threshold. Not “conversion is low” but “people fall off at the trust gate because there is not a single human sentence about who we are”.

Check the floors in order, bottom to top. A common mistake: the button gets rewritten and a discount gets added, when people fall off on the first screen and never reach the button. First make sure the person has recognised you as theirs. Then look at trust. Only at the end, for the warmed-up, polish the calculation. Fix from the top down and you will be polishing a door nobody climbs to.

Test it on yourself in two minutes

Recall a purchase you made on autopilot: coffee on the way somewhere, a subscription you did not need, something from a sale. Now lay it out by floor. What worked at the bottom, before any thought: the habitual route, a familiar logo, the colour of the price tag? What tugged in the middle: fear of missing out, someone’s review? And did it reach the top at all, or did you invent the explanation afterwards?

Almost always the same thing turns up. What we proudly call intuition is ordinary processing on a floor that consciousness has no direct access to. Not magic. A door you did not see, through which the signal passed.

While you sort people into “rational” and “emotional”, you are working with two enormous stickers. Once you see floors and gates, you have a screwdriver instead of a sledgehammer. You find one threshold and work on it.

That is where a review of how your product is perceived begins: with the floor on which your buyer says “no” before they had a chance to say “yes”. For a Russian funnel, the free review does exactly this, floor by floor.

A buyer’s brain is not a switch. It is a staircase, and every step has its own door.
