The first two pieces in this run were about desirable difficulty: capture less so you have to remember, let old cards resurface so you remember again. This one is a cousin, not a sibling. It rests on a different line of research, and I want to be clear about that rather than fold it in where it doesn't belong.
The habit is the one the whole app is named for. When I make a card, I link it. A meeting connects to the project it was about, the project connects to the trade show where it started, the trade show connects to the person who introduced me to all of it. I don't build these links to keep things tidy. I build them because following them later is how the whole thing comes back.
Elaborative encoding is the finding that we remember things far better when they're tied to other things, anchored into a web, than when they sit on their own. An isolated fact is a loose page. The same fact tied to five things you already know is held in place by all five. Memory isn't a warehouse where you store items side by side. It's a network, and the more honest connections an idea has, the more ways back to it you've got.
So when iXnote shows you a card, it never shows it alone. It opens the card already in its context, with everything it connects to sitting around it, because the context is the point and the lone card never was. The graph isn't a filing cabinet with a nice view. It's the encoding. Every link you make is a memory you're building, not a folder you're sorting.
But connections only help when they mean something. A card wired to thirty others isn't richly encoded, it's noise, and noise is worse than a clean isolated note, because now you can't find anything. The same discipline that governs what to capture governs what to connect: a few real links beat a hundred lazy ones.
Linking is thinking. But only when you mean it.
