I made a table of your system. I can’t upload a picture, so I drew a simplified one using my keyboard:
|-----------------|------------------|-----------|-----------|-----------|-----------|
|-----------------|.........1..........|.....2.......|.....3......|.....4......|.....5......|
|-----------------|------------------|-----------|-----------|-----------|-----------|
|.Universality.|......HIGH......|............. |..LOW...|..HIGH..|..LOW...|
|-----------------|------------------|-----------|-----------|-----------|-----------|
|.Accuracy.....|.....................|..............|..HIGH..|..LOW...|..LOW...|
|-----------------|------------------|-----------|-----------|-----------|-----------|
|.Productivity.|..NOT..LOW..|..HIGH..|..............|.............|..LOW...|
|-----------------|------------------|-----------|-----------|-----------|-----------|
1. Foundations, 2. Constructions, 3. Empirics, 4. Interpretations, 5. Speculations.
This visualised form of your system helped me notice a few things:
First, an idea cannot be both highly universal and highly accurate (though it can be low on both). Otherwise, your system would fail to account for certain possible outcomes (HIGH, HIGH, [ANY]).
Second, levels 2 and 3 can be determined solely by Productivity and Accuracy respectively, provided those values are high.
Third, both levels 1 and 4 can be identified by their high Universality. In fact, they can share the same combination: high universality, low accuracy, and not-low productivity. This makes distinguishing between the two levels ambiguous. But this is not a weakness. On the contrary, I think it shows that your system reflects real-life situations quite well. Often, the difference between interpretation and foundation can be just a matter of belief—I (or we as a society) strongly believe certain things to be true, and so they become foundational within my (our) worldview.
And, of course, level 5 is also clearly defined, as it lacks any high values.
Nicely done. I really enjoyed analyzing your system.
