As crises multiply, ingenuity lags. This prescient classic explains why societies falter when problems outpace solutions—and offers a roadmap to close the gap before risks from climate shocks, pandemics, inequality, and AI spiral beyond control.First published at the turn of the millennium, The Ingenuity Gap by Thomas Homer-Dixon anticipated the turbulent world we now inhabit: pandemics, climate disasters, political polarization, disruptive runaway technologies, and escalating global instability. With remarkable foresight, Homer-Dixon warned that the complexity of our problems would accelerate faster than our collective ingenuity to solve them—and that failure to close this “gap” would leave societies fragile and exposed. A quarter century later, his vision has proven prophetic.Homer-Dixon takes readers on a global tour of ingenuity under pressure: from the desperate improvisation of pilots fighting to land United Airlines Flight 232 in Iowa, to the water-hungry expansion of Las Vegas, to a harrowing search for a missing child in Patna, and the collapse of Canada’s cod fisheries. Vivid and far-reaching, it is a sweeping portrait of what happens when societies are stretched beyond their capacity to adapt and an enlightening case for why ingenuity is humanity’s most vital resource.Celebrating over twenty-five years in print, The Ingenuity Gap remains both a visionary diagnosis of our age and a call to reimagine how we generate creativity, resilience, and leadership in uncertain times.
