But there is a ton of evidence that the foundations of many societies are shifting and not for the better. That doesn't immediately reflect in the statistics (death tolls, crime rates) until a certain critical mass has been reached.
Just like you can't tell a tsunami from a small wave visually until it reaches the shore.
There isn't a country in Europe that has not moved substantially towards nationalism in the last decade or so. The foundations of Europe are being attacked and countries that were relatively stable (Turkey, Greece, Spain, UK) are all facing internal forces strong enough to change those countries in substantial ways. Then there is Ukraine (which is far from over) and Syria.
All in all, 'science' is in this case mostly tallying up the dead a couple of years after the bodies hit the ground. It's lagging behind the curve considerably and it doesn't even log places like Iraq and Syria in those statistics because they are anomalies.
