Do your emotions affect how daring you are?
Yup – especially if that emotion is fear. Two psychologists in Australia, winners of the Ig Nobel in Economics in 2017, gave $20 to more than 100 tourists before or after they held a roughly three-foot-long saltwater crocodile. Then they asked them to use that money on a virtual slot machine. It turns out that holding a crocodile makes you less likely to take risks: Most people without gambling problems made smaller bets afterward, possibly because animals that could rip your fingers off remind you to be more cautious.
