A good title compresses an idea down to something you can use in argument without reopening the full note. A claim-based title functions as a handle that slots into another note’s argument naturally. A note that holds too many ideas produces a title that’s either too broad to be useful or too narrow to be honest about what’s inside.
Non-linear note making depends on this, connections between notes only travel if the title carries the idea clearly enough to work in a new context.
