We humans are born with a craving for fat and sugar. But we are also born with a craving for drama. We pay attention to dramatic stories and we get bored if nothing happens.

Journalists and lobbyists tell dramatic stories. That’s their job. They tell stories about extraordinary events and unusual people. The piles of dramatic stories pile up in people’s minds into an overdramatic worldview and strong negative stress feelings: “The world is getting worse!”, “It’s we vs. them!” , “Other people are strange!”, “The population just keeps growing!” and “Nobody cares!”

For the first time in human history reliable statistics exist. There’s data for almost every aspect of global development. The data shows a very different picture: a world where most things improve; a world that is not divided. People across cultures and religions make decisions based on universal human needs, which are easy to understand. The fast population growth will soon be over. The total number of children in the world has stopped growing. The remaining population growth is an inevitable consequence of large generations born decades back. We live in a globalized world, not only in terms of trade and migration. More people than ever care about global development! The world has never been less bad. Which doesn’t mean it’s perfect. The world is far from perfect.
