You’re on an airplane talking pleasantly to a stranger of average appearance. Unexpectedly, the person offers you $ 30,000 for one night of sex. If you knew there were no danger and you’d get the money, would you do it? If the payment were meaningfully raised or lowered, at what point would you change your answer?

  • How would the age and gender of the person affect your answer? What is the difference between having sex for immediate cash and having sex in the hope of other future benefits?


For $ 30,000 would you go for 2 months without washing, brushing your teeth, shampooing, or even using deodorant? Assume you can’t tell anyone why.

  • Which would disturb you more: forgoing basic hygiene for months or having sex with a stranger?


If a new medicine would cure arthritis but kill 1 out of 100 people who took it, would you want it to be legal? What about a vaccine that would kill 1 in 20, but keep the others from getting cancer?
