According to prominent Harvard psychologist Steven Pinker, statistics reveal dramatic reductions in war deaths, family violence, racism, rape, murder and all sorts of mayhem.
In his book, Pinker writes: "The decline of violence may be the most significant and least appreciated development in the history of our species."
And it runs counter to what the mass media is reporting and essentially what we feel in our guts.
Pinker and other experts say the reality is not painted in bloody anecdotes, but demonstrated in the black and white of spreadsheets and historical documents. They tell a story of a world moving away from violence.
