Why Defaults Beat Cash: The Afghanistan Savings Experiment That Shocked Economists

Imagine getting poor people to save money without paying them a dime. In war-torn Afghanistan, where only 4% of adults use banks, a simple default setting on mobile phones boosted savings by 40 percentage points—as effectively as handing out 50% cash match. This video unpacks the groundbreaking experiment by Blumenstock, Callen, and Ghani, revealing how present bias and cognitive costs trap us in inertia. We'll show why defaults work better than money, how they reshape attitudes, and what this means for global poverty and retirement systems. No jargon, just mind-blowing insights.
