Short‑video temptation horizon

Short videos create fleeting decisions that repeatedly renew temptation, producing a measurable 'horizon' over which users struggle to stick to plans; microdata can estimate that horizon (here ~11 minutes) and the resulting overshoot in consumption (here 82.1% for paying users). Larger decision units, default limits, and enforced breaks reduce overshoot in counterfactual simulations. — Naming and measuring a 'temptation horizon' links product design to behavioral harm and gives regulators, platforms, and researchers a concrete target for policy and intervention.
