Best interview podcast out there

Been listening for three years now. The guests are always interesting and the host does his homework. The episode with the former intelligence officer was wild. Genuinely one of the few podcasts where I never skip episodes.

Not what I expected

Some episodes are genuinely great but others feel like thinly veiled promotions for the guest's book or course. The ad reads are also getting out of hand. Used to be better.

Methodology

PROOF analyzes 12 independent signals across 4 dimensions (temporal patterns, content analysis, account characteristics, and statistical distribution) using a weighted ensemble scoring methodology. Each review receives a composite pattern score from 0.0 to 1.0, calibrated against observed norms across thousands of Apple Podcast reviews. Findings are classified using interquartile range (IQR) percentile thresholds: P25–P75 = Expected, P10–P25 / P75–P90 = Notable, tails = Anomalous.
