Does Positive Psychology actually make a difference, or is it overhyped?

A foundational meta-analysis of randomized controlled trials found positive psychology interventions produce small-to-moderate improvements in wellbeing and reductions in depressive symptoms. Weighing the data: Positive Psychology looks an early-stage, lower-priority area for now — the evidence is only moderate (62/100), and its estimated impact (40/100) is on the lower end too.
