I don't know : in praise of admitting ignorance and doubt (except when you shouldn't)
(Book)

In a tight, enlightening narrative, Leah Hager Cohen explores why, so often, we attempt to hide our ignorance, and why, in so many different areas, we would be better off coming clean. Weaving entertaining, anecdotal reporting with eye-opening research, she considers both the ramifications of and alternatives to this ubiquitous habit in arenas as varied as education, finance, medicine, politics, warfare, trial courts, and climate change. But it's more than just encouraging readers to confess their ignorance--Cohen proposes that we have much to gain by embracing uncertainty. Three little words can in fact liberate and empower, and increase the possibilities for true communication. So much becomes possible when we honor doubt.
