Bottom-up approach to hierarchy

Start at many, keep consolidating to one

Two copies of the standard simple hierarchy diagram. The top one has a single node at the top; the bottom one has a single node at the bottom. The entry points are blue, and in the most populated line; the link to the next level has a red arrow pointing from the entry to the consolidation. In the top diagram, the arrows point up to the row of 4 nodes. In the bottom diagram, the arrows point down to the row of 4 nodes.

With a bottom-up approach, someone(s) is taking all the data and forming categories from the data.

I’ve seen people look at the final representation and insist that the defining node is still the single one alone on its line. This is despite any visual signals or verbal/written course correction. They see the stack and know what they know, their brains turning it to read the ‘right’ way. It’s a form of cognitive bias.

What tends to happen when bottom-up hierarchy is the initiating architecture


This is mostly based on first- to third-person watching. It’s been influenced by library studies, UX, and democratic standards.

bottom-up:
cognitive bias, context, emotions, garbage-in, taxonomy
