The 16 Axes of the Evidence Spectrum

An expanded framework for even more nuanced evaluation, adding eight dimensions to the original eight. The additional axes include: 9) Temporal Relevance (how current the evidence is), 10) Ecological Validity (how well the evidence reflects real-world conditions), 11) Mechanistic Understanding (whether we know why the evidence works), 12) Alternative Explanations (how thoroughly competing explanations have been ruled out), 13) Effect Size (how large the observed effect is, not just whether it's statistically significant), 14) Precision (how narrow the confidence intervals are), 15) Generalizability (how well the findings apply across contexts), and 16) Transparency (how fully the methods and data are available for scrutiny). The 16 axes provide a nearly complete picture of evidential quality, useful for high-stakes decisions where nuance matters.

The 16 Axes of the Evidence Spectrum *Example: "The policy debate was high-stakes, so they used all 16 axes. The evidence was strong on reliability and rigor, weak on ecological validity and generalizability. The 16 axes showed exactly where the uncertainty lay—not in whether the evidence existed, but in how well it applied. The policy was informed, not determined, by evidence—which is how it should be."*
