Reach and substance are not the same thing. These shows score highest on what we can actually measure: information density, specificity of claims, and how often they credit their sources.

Specificity of claims. Acquired: Specificity 69. The AI Daily Brief: Specificity 72. Last Week in AI: Specificity 64. BG2 Pod: Specificity 73. Gradient Dissent: Specificity 65. Invest Like the Best: Specificity 75. Specificity measures how concrete and checkable the claims are, versus vague punditry.

How we score: every show is graded from its episode transcripts on information density (named companies, people, figures, and mechanisms per minute), specificity (concrete, checkable claims versus vague punditry), source attribution (how often a claim credits where it came from), and a prediction track record we resolve against what actually happened. The full, continuously updated board lives at [the podcast rankings](/rankings/podcasts).
