The next time you find yourself in a casino, pause for a second to appreciate the architecture.
Casinos put an enormous amount of thought into their designs. The layout of the tables, the patterns on the carpet, the lighting — they're all explicitly engineered to make gambling more seductive and get you to spend more money.
One surprising example are the curving hallways around the property. Many casinos try to avoid making you ever have to turn at a 90° angle. As Natasha Dow Schüll explains in her fascinating book, Addiction By Design: Machine Gambling in Las Vegas, a right-angle turn forces people to call upon the decision-making parts of their brain — to stop and reflect on what they're doing. "Casinos don't want that," Schüll told me. "They want to curve you gently to where they want you to go."
