The failure of linear notes
Four structural flaws in classic note-taking, and what they cost you.
What you will find
Open one of your meeting notebooks. Look at a page written three months ago.
Three questions. Can you find the key piece of information in under fifteen seconds? Can you see what mattered and what was incidental? Do you know which actions followed from it?
In the great majority of cases the answer is no to all three. This is not a discipline problem: it is a format problem.
Flaw 1: no visual hierarchy
In a block of text, a decisive sentence and a passing remark carry exactly the same visual weight. You have to reread everything to find out what counts.
A mind map encodes importance in position and in thickness: the centre is decisive, the periphery is detail. The information is seen before it is read.
Flaw 2: no visible links
Your linear notes contain relationships: causes, consequences, oppositions, dependencies. But they are lost inside the syntax, inside a therefore, a however, a which implies.
Three weeks later those connectors no longer jump out. A map makes the links structural: a branch growing out of another one is a relationship.
Flaw 3: passive transcription
Writing word for word occupies the hand and switches off the head. You become a recording device.
The result is documented: students taking notes on a laptop write more words and retain less than those writing by hand, in the work of Mueller and Oppenheimer published in 2014. The explanation the authors hold to: the slowness of the hand forces you to rephrase, and rephrasing is the processing.
A mind map pushes that same constraint to its limit: you can only write keywords, so you have to sort and rephrase in real time.
Flaw 4: no way to add
You note three points on a subject, you move on, and the speaker comes back to the first subject ten minutes later. In linear notes that information lands three pages further on, disconnected.
On a map you go back to the branch in question and add to it. The structure stays true.
What it actually costs
Taking unusable notes costs you twice: the time to take them, and the time to reprocess the information from scratch when you need it.
The real indicator of good note-taking is not completeness. It is how long it takes you to reconstruct the subject from your notes. Target: under two minutes.
What linear notes lose, what maps keep
Linear notes
- Everything has the same visual weightYou have to reread it all to find the essentials
- Links are buried in the syntaxTherefore, however: invisible three weeks later
- Passive transcriptionThe hand busy, the head switched off
Mind map
- Importance is encoded by positionThe centre is decisive, the periphery is detail
- Links are structuralA branch growing from another one is a relationship
- The keyword forces you to sortYou cannot transcribe, so you process
Exercises1
Understanding produces no change. These exercises are what makes the difference: each one has a measurable success criterion.
The test on your old notes
Measure what your current notes actually cost you, in seconds.
Equipment : Three pages of your old notes, a timer.
- 1.Take three pages of notes written more than a month ago.
- 2.Time how long it takes you to extract the three main ideas from them.
- 3.Time how long it takes you to find the actions that followed from them.
- 4.Write both figures down and keep them: you will compare them at the end of the module.
Success looks like : You have two figures written down, and you can see that extraction takes far longer than the two minutes we are aiming at.
The classic mistake : Choosing recent notes that you still remember. The test only means something on cold notes.
