Mental Models: Think Clearly, Decide Better · Lesson 1 of 12 · 12 min

The map is not the territory

CVs, reviews, plans and budgets are all maps: useful simplifications that leave things out. Learn to spot what a map drops and check the ground before a big decision.

The map is not the territory

MENTAL MODEL

Any description of reality is a simplified picture of it, not the thing itself. The phrase comes from Alfred Korzybski, who wrote in the 1930s about how easily we confuse our words and pictures with the world they describe. A map is useful exactly because it leaves things out. The trouble starts when you forget that it did.

A city map shows streets, not potholes, smells or the fact that one road is closed today. You still want the map. You just don't argue with the road when the two disagree.

MAPS EVERYWHERE

Most of what you decide from is a map

You rarely see the territory directly. You see a CV, not the person's working day. A 4.6-star rating, not the phone in your hand after a year. A business plan, not the customers. A job ad, not the team. Each one was made by someone, for a purpose, with choices about what to show.

A CV is a map drawn by the person it describes, built to get an interview. That doesn't make it false. It tells you what kind of things it will leave out.

Check yourself

Neda is choosing between two phones. One has 4.7 stars from 3,000 buyers, the other 4.3. She is about to order the first without reading anything else. What is the map leaving out that matters most to her?

  1. Nothing: 3,000 ratings is a large sample, and a large sample is enough to decide on
  2. What the buyers cared about, and when they rated the phone
  3. The rating is probably paid for, so she should ignore the stars and choose on price
  4. The exact number of five-star votes
Show the answer

What the buyers cared about, and when they rated the phone

Yes. The average squeezes thousands of different people and moments into one number. It mostly captures first impressions, and Neda cares about year two.

The navigation app and the closed road

Your navigation app says turn left. In front of you is a barrier and a digger. Nobody keeps driving. You trust your eyes, and the app reroutes. With other maps we are less sensible: the spreadsheet says the business makes money, so we ignore that nobody is buying. Where the analogy breaks: a closed road is obvious. In most decisions the territory doesn't put up a barrier. You have to go and look.

Same flat, two views

The listing (map)

75 square metres, renovated, bright, 10 minutes to the metro. Six wide-angle photos taken at noon. Written by someone who wants it rented this week.

The visit (territory)

The 10 minutes is for a fast walker with no traffic lights. The bedroom faces a street that is loud at night. Water pressure is weak on the fourth floor. The neighbours are lovely.

Map or territory?

  • A company's page about its 'friendly, flexible culture'
  • Sitting with the team for half a day before you accept
  • Your monthly budget in a spreadsheet
  • Your bank statement at the end of the month
  • A friend's summary of a contract
  • Standing in the flat at 10pm and listening

Three questions for any map

  1. Who drew it, and why?

    A seller, an applicant, a fan, your own hopeful self last January. The purpose tells you which way it leans.

  2. What did it have to leave out?

    Every map drops detail to be readable. A CV drops how someone handles conflict. A plan drops everything that hadn't happened yet when it was written.

  3. What is the cheapest look at the ground?

    A visit at a different hour. A call to a former employee. Selling to five real customers before printing a thousand. The bigger and harder to undo the decision, the more this step is worth.

Check yourself

Kaveh wrote a careful 12-month plan for his online shop. In month three, sales are a third of what the plan says. The sensible move is to stick to the plan, because he thought hard when he wrote it.

Show the answer

False

The plan is a map drawn before the trip. Three months of real sales are the territory. When they disagree, the plan is what needs redrawing. Hard thinking at the start doesn't outrank what actually happened.

Check yourself

Shirin has a job offer. The ad promised 'flexible hours and fast growth'. The interview went well. She has a week to answer. Which step uses this lesson best?

  1. Talk to two people on the team about a normal week, and check how long people stay
  2. Accept now: the ad and the interview agree with each other
  3. Reject it, because job ads always exaggerate and an interview is a performance
  4. Read the ad again line by line to find the hidden hints about what the job is really like
Show the answer

Talk to two people on the team about a normal week, and check how long people stay

Right. The ad and the interview are two maps drawn by the same side. A conversation with the team and how long people stay are a cheap look at the ground.

Match each map to what it usually leaves out

Show the answer
  • A CV → How the person behaves under pressure
  • A star rating → How the product holds up after a year
  • A flat listing → Noise at night and the real walk to the metro
  • A business plan → Whether real customers will pay

Lesson recap

  • Every CV, review, plan and budget is a map: a useful simplification made by someone for a purpose.
  • Ask three things: who drew it and why, what it had to leave out, and what the cheapest look at the ground is.
  • When the map and the territory disagree, update the map.
  • Don't swing to the other side: your gut feeling is a map too.
