Episode Description from the Publisher

You didn't want the Large fries. In this episode of Lies We Bought, we unpack the "Bigger is Better" business model. We explore the psychological traps that make "more" feel like the only rational choice, from fast food menus to the SUV loophole. Inside this episode: The Origin of "Large": How David Wallerstein invented the large fry to boost margins. The Decoy Effect: Why pricing tiers are designed to trick your brain into spending more. Unit Bias: The famous "bottomless soup" experiment and why we eat more than we need. The SUV & McMansion Era: How fuel standards and building trends doubled our lifestyle size while families shrank. "Bigger is better" isn't a natural law; it's a margin strategy. If you’ve ever upgraded for forty cents, this episode is for you. Enjoyed the episode? Drop us a review! It helps other people realize they don't need that XL soda either. P.S. This episode is the shortest one yet on purpose - because bigger isn't always better.
