A tiny experiment with note types
Last week, I started a small experiment involving three different types of notes (Permanent Notes). My Zettelkasten analysis showed the following numbers:
- #type/proposition = 68,5%
- #type/question = 31%
- #type/observation = 0,5%
Just an observation. I hope to discover some related and useful propositions and questions within the next few weeks.

What have your experiences been like when trying out structural experiments with your Zettelkasten?

I've ran several experiments with structure, but in the end I always come back to the same conclusion, which is to keep it simple. I always regret it and reverse it when I make anything more complicated than it needs to be.
The experiments I end up keeping are the ones that work across my entire Zettelkasten in a consistent way. If an experiment only seems to work for a particular set of notes, then it makes me think that those notes will become isolated and lose the benefits of connection to the whole.
I'll keep experimenting, but will always ask how this experiment fits into the entire process and helps with my overall goals.
If I were to run your experiment on my notes, I'd probably have way more observations, so it's interesting how your percentages turned out. Maybe that's just because of the particular set of notes you applied it to.
I've experimented with type and scope annotations but so far haven't gotten much value out of them. That could change in the future, perhaps.
I have an experimental script that returns a "Concise Bounded Description" (CBD) of a z-card. This shows all cards that have links to the selected card, and then all cards that have links to them. One could extend the CBD beyond two tiers, but the extra levels would produce many more results whose connections would be increasingly diffuse so I haven't tried more tiers so far. This can sometimes be helpful. The script produces clickable links for each hit so navigating to any of them is easy.
I have tried creating temporary and provisional sections and I've found them to be very useful.
The model is very interesting. Thinking about it, it partially reflects what I do, but with a probably fundamental difference: I don’t make those type of notes explicit (they are all "permanent notes"), they behave in a certain way only because of their placement within the note that contains them.
If an observation is strictly specific to a proposition, I integrate it directly into the note it supports; if it can support multiple notes or has relevance independent of the others, I create a dedicated note and I make use of links. In any case, I don’t have explicit types, as already stated. A text is an observation if it behaves like an observation when contained within a note or linked within a note.
I could consider this a kind of “duck property” of my notes: if it works like… then it is…
I obviously can’t measure percentages, because since the notes aren’t typed, I wouldn’t know how to count the different kinds of notes 🙂
I try out new ideas with a few notes to see if the idea works at all.
Small scale experiments make it easy to explore many variants.
Experiments with real data help weed out ideas that looked promising in theory, but fail to produce the desired effects in practice or even introduce undesirable side effects.
Yes, that's a useful threshold.
When I make structural changes, I apply them to the whole ZK. A consistent ZK is easier to update.
Yes!
