> Does "levels" mean "depth"? To give the feel how deep in the subject you are?
Yes! Level means depth.
> Don't stacked "parents" give that feel?
No! The stack doesn't give me that feel, because visually, it doesn't look like a stack. My brain perceives a series of plain text lines as a block of information. There's a reason we add symbols (numbers, discs) to checklists. We want them differentiated from normal text blocks. Of course you don't necessarily need to use symbols, you could also make use of relative positioning (between levels) or color (varying the intensity of the same color as you move up and down the levels, or use a color theme), etc.
You might want to checkout the way 'Thebrain' 1) can show related thoughts using layers of transparency. Our brain reads these indirectly and helps providing contexts.
Ha. Nice. Thank you. Never seen this one, but seen some other visual fractal notebook/s. Some, for sure, may find it (zooming map) more convenient and fun than navigating text. I, personally, don't feel it's web/screen friendly. Maybe for some VR it could work much better. Would be cool to try.
Yes, it is the power of this manipulation — even seeing data does not help, but:
"Among the participants reporting child abuse (25% of all respondents), 48% had a tattoo or piercing" ― out of 100 people, 25 were abused and 48% of them (i.e. 12 people) have tattoos → 12 of 100 respondents have tattoos and were abused, while 28 just have tattoos.
