People often expose themselves to negative tail risk by taking on losing bets in which randomly-occurring major losses eradicate all previous gains. Why is this? Here I present evidence from a collection of laboratory experiments aimed at testing several plausible causal explanations. All these explanations are falsified except for the proposition that people are greedy and lack self-control. These findings highlight the importance of purely behavioral factors (alongside and independent of cognitive factors) in helping to understand how people respond to tail risk.
