From his notes on visiting Europe:
When I taught my German students Kuran and Sunstein’s availability cascades model, I used terrorism as a prime example. Over a thousand people are murdered on Earth on an average day. Every death is a tragedy, but there’s no good reason to treat the small minority of terrorist murders as disproportionately important or revealing, except in the trivial sense than countries overreact to terrorism. I know this is an unpopular view, especially after a major attack, but I love numeracy more than popularity.
