Say you have a load of donated food to deliver to an orphanage in Uganda. But due to circumstances beyond your control, you're forced to make a hard choice: give some of the children enough meals to stave off hunger for several days and let the rest go hungry, or evenly distribute a smaller amount of food so that each child feels full for just a few hours. A study published online today in Science is one of the first to investigate how the brain wrestles with such morally charged tradeoffs.
