If ever there is tomorrow when we’re not together, there is something you must always remember. I’ll always be with you.
One of the most surprising findings is that people have a natural aversion to inequality. We tend to prefer a world in which wealth is more evenly distributed, even if it means we have to get by with less.
Consider this recent experiment by a team of scientists at Caltech, published earlier this year in the journal Nature. The study began with 40 subjects blindly picking ping-pong balls from a hat. Half of the balls were labeled “rich,” while the other half were labeled “poor.” The rich subjects were immediately given $50, while the poor got nothing. Such is life: It’s rarely fair.
The subjects were then put in a brain scanner and given various monetary rewards, from $5 to $20. They were also told about a series of rewards given to a stranger. The first thing the scientists discovered is that the response of the subjects depended entirely on their starting financial position. For instance, people in the “poor” group showed much more activity in the reward areas of the brain (such as the ventral striatum) when given $20 in cash than people who started out with $50. This makes sense: If we have nothing, then every little something becomes valuable.
But then the scientists found something strange. When people in the “rich” group were told that a poor stranger was given $20, their brains showed more reward activity than when they themselves were given an equivalent amount. In other words, they got extra pleasure from the gains of someone with less.
