Complexity vs Empirical Score

  • Math Complexity: 2.0/10
  • Empirical Rigor: 3.0/10
  • Quadrant: Philosophers — conceptual discussion, limited math and data

Why this score: The paper is a literature review summarizing existing findings with minimal original mathematical derivations or models, and while it discusses empirical results, it does not present new backtests, datasets, or implementation-heavy analysis.
