This has been around for some time, but is worth having a look at to keep some things in perspective. Not that it helps much if you live in some hell-hole where order has broken down or your freedom is suppressed ... and not that Western countries are magically immune to turning into hell-holes. It takes work, and a commitment to the values of peace and tolerance.
For all that, some things have been improving over time.
Steven Pinker is one of my favourite writers, and he's also a very good speaker.
