As Dina and Amy go searching for Bo, Amy notices that Dina doesn’t have a radio in her truck. It turns out that Dina special-ordered her truck without a radio (even though it costs more) because she believes it would make her truck less appealing to potential thieves. If criminals behave rationally (which Gary Becker argued that most do), a truck without a radio wouldn’t be worth the potential cost associated with car theft. Dina has removed the incentive to steal her truck.
When it comes to selecting numbers for a lottery, people tend to irrationally believe certain numbers are more important than others. Each number is just as likely to be selected as the other numbers, so placing a higher probability on one number being selected isn’t rational. Garret isn’t fooled, but he also isn’t fond of wasting his time watching others behave so irrationally.
Glenn wanted to see Saw because he thought it was about carpentry, but he quickly realized it was a horror movie. He wasn’t having a good time and even threw up in his lap, but his wife didn’t want to leave because they paid for the ticket and it was date night. Glenn and his wife should have left if they weren’t enjoying their movie since the tickets were non-refundable, but like many people, Glenn and his wife fell for the sunk cost fallacy.
