If you think the world is coming to an end, think again: people are living longer,
healthier, freer, and happier lives, and while our problems are formidable, the solutions lie in the Enlightenment ideal of using reason and science. Bill Gates called it "My new favorite book of all time." This book helped change my perception of the world from a negative slant to a view of optimism and hope. I can't recommend it enough. It is 476 pages chock-full of data, graphs, and thoughtful narrative.
The author, Steven Pinker, Johnstone Family Professor of Psychology at Harvard University, draws from hundreds of sources to support the books claim. One prominent source is www.ourworldindata.org. If you're a data geek, like me, you could spend hours perusing the 3431 charts across 297 topics. One of my favorites is the chart projecting world population growth. Few people realize that as the world populace becomes wealthier, we have fewer children and population is actually expected to begin declining in the next century.
If you're skeptical and still have questions like "What about climate change?" or "What about mental health and social connection?", you definitely should grab a copy.
