Structured interviews with standardized questions and scoring are proven to predict job performance far better than unstructured interviews that rely on subjective cultural fit judgments.

Interval Training's Fat Loss Edge: Missing Data and Cardio Evidence

The cardio-versus-intervals argument drags on partly because fat loss studies are riddled with dropouts and missing measurements. This take argues that when those gaps are filled with rigorous statistical methods instead of ignored, high intensity interval training pulls clearly ahead of steady state cardio. If you care what the evidence really says, the way researchers handle incomplete data should change which workout you trust.
