What do you mean, good”?

Try thinking of “good” as a measure of how much a country contributes to the common good. So in this context “good” means the opposite of “selfish”, not the opposite of “bad”. The Good Country Index isn’t trying to make any moral judgments: it just measures, as objectively as possible, what each country contributes to the common good, and what it takes away, relative to its size. I've found that the importance of this is something most people in most cultures can agree on. It certainly helps that every major religion teaches the same truths: that it's our responsibility to look after the planet, and that all men and women are our brothers and sisters.
