24 Imagine the U.S. is preparing for the outbreak of an unusual Asian Flu which will kill 600 people if we do nothing.

25 If program A is adopted, 200 people are saved. If program B is adopted, there is a 1/3 chance of saving 600 and a 2/3 chance of saving nobody.

26 If program A is adopted, 200 are saved. If program B is adopted, there is a 1/3 chance of saving 600 and a 2/3 chance of saving nobody.

27 If program A is adopted, 200 are saved. If program B is adopted, there is a 1/3 chance of saving 600 and a 2/3 chance of saving nobody. If program C is adopted, 400 people die. If program D is adopted, there is a 1/3 chance that nobody dies and a 2/3 chance that 600 will die.

28 If program A is adopted, 200 are saved. If program B is adopted, there is a 1/3 chance of saving 600 and a 2/3 chance of saving nobody. If program C is adopted, 400 people die. If program D is adopted, there is a 1/3 chance that nobody dies and a 2/3 chance that 600 will die.

29 If program A is adopted, 200 are saved. If program B is adopted, there is a 1/3 chance that 600 are saved and a 2/3 probability of saving nobody. If program C is adopted, 400 people die. If program D is adopted, there is a 1/3 chance that nobody dies and a 2/3 chance that 600 will die.

33 moral intuitions profoundly morally irrelevant Lingering sense of unease about our moral intuitions since they are often profoundly influenced by things seem morally irrelevant. Look a bit differently about advice that relies or appeals to our moral intuitions.
