Original Text

We've seen this problem before. It's called a social dilemma. And to understand the social dilemma, we have to go a little bit back in history. In the 1800s, English economist William Forster Lloyd published a pamphlet which describes the following scenario. You have a group of farmers — English farmers — who are sharing a common land for their sheep to graze. Now, if each farmer brings a certain number of sheep — let's say three sheep — the land will be rejuvenated, the farmers are happy, the sheep are happy, everything is good. Now, if one farmer brings one extra sheep, that farmer will do slightly better, and no one else will be harmed. But if every farmer made that individually rational decision, the land will be overrun, and it will be depleted to the detriment of all the farmers, and of course, to the detriment of the sheep.
