Ratios of the Mind

Organizing information into a pyramid shape is a powerful approach to developing keen judgment. The hierarchical structure of a pyramid facilitates both top-down and bottoms-up understanding of the parts and whole of a situation. Ten named ratio categories are a powerful tool to exploit a pyramid information structure. Breaking down a situation into three primary components is a more precise technique, because math aids the decision process. 

Separating information into three primary groups improves judgment by reducing information noise. The Doing, Feeling and Thinking parts of our mind compete with our Center of Attention. Knowing where your Center of Attention lies will shift as knowledge, habits or feelings change. A similar Benefit, Cost and Risk concept exists to resolve Value.

A flexible information structure allows the breadth and depth of information to be configured, without conscious awareness. The app information structure lies in the background, providing easy access when desired.
