Why Most People Buy Things They Don't Need (Anchoring Bias Explained)

Two boxes of oats, same brand, same shelf, one priced at $4.99 and one at $5.49. You didn't compare either price to anything real. You compared one number to one other number, for one second, and your hand moved. This video breaks down the anchoring bias, and why it is not a marketing trick that happens to work on people in supermarkets, it's a fundamental feature of how your brain estimates anything: prices, salaries, prison sentences, medical diagnoses, even how happy you believe your own life is.
