What Your Hungry Ancestors Did to Your Bank Account

You just got paid — and by tonight, a little less of it will be there. The real reason isn't weak willpower. It's 2 million years of hunger, wired deep into your brain. In this video we trace the hidden evolutionary programs behind your spending: why a "SALE" sign gives you a physical thrill, why losing money hurts twice as much as gaining it, and why being broke actually makes it harder to think your way out. Along the way we meet the research that proves it — from Kahneman and Tversky's loss aversion, to Mullainathan and Shafir's scarcity studies, to the Minnesota Starvation Experiment and the famous marshmallow test.
