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 theoretical review of the Efficient Markets Hypothesis with only basic statistical tests and no backtesting or code, focusing on conceptual foundations rather than mathematical derivation or empirical implementation.
