About Mental Model Atlas

Mental Model Atlas is an open project dedicated to constructing a “Map of Thought” within the Japanese-speaking sphere.

In our complex modern society, we aim to provide an “Intellectual OS” to facilitate better decision-making and essential problem-solving.

Project Objectives

Rather than a mere accumulation of information, we are building a “Thinking Toolbox” centered on the following three pillars:

Systematization: Organizing scattered insights into a unified format.
Structuring: Clarifying relationships based on abstraction levels and thinking types.
Practicality: Presenting “Recipes”—combinations of models suited to specific situations.

📊 Definition of Evaluation Scores (1–5)

On this site, each mental model is uniquely scored across four dimensions. This serves as a guide (contour line) to help you determine “which thinking tool to pick up right now.”

Item	Description	1 (Min)	5 (Max)
Versatility	Degree of general applicability	Limited to specific fields	Universal across all domains
Immediacy	Speed of effect after learning	Requires long-term practice	Usable the moment you learn it
Difficulty	Complexity of the concept	Intuitively understood	Requires high-level abstraction
Misuse Risk	Danger of misinterpretation	Low potential for harm	Risk of backfiring or mental bias

Note: These scores are “provisional values” based on the editorial team’s subjective assessment. Since they vary depending on the user’s context, please use them as a general reference.

🗺 Roadmap

Phase 1 (Current): Publication and structuring of 50 selected models.
Phase 2: Expansion of featured models (100–200) and strengthening classification by “Thinking Type.”
Phase 3: Introduction of “Thinking Recipes” (combining multiple models) and graph visualization.
