Why do we fear the wrong things? We worry about plane crashes but not car rides, strangers but not algorithms, sharks but not sugar. In The Fear Knot: How Science, History, and Culture Shape Our Fears – and How to Get Unstuck, journalism professor Ruth DeFoster and neuroscientist Natashia Swalve explore why our brains evolved to fear what once kept us alive — but now often misleads us. The result is a timely, eye-opening look at how to separate fact from fear in a world that profits from keeping us anxious.
