In a world of 280-character sound bites, talk radio misinformation, cable television shouting, and political violence, podcasts have become the go-to place for civilized conversation.
The explosion of podcasts no doubt reflects their unique ability to convey information in an intimate and uncluttered fashion.
From the many podcasts WhoWhatWhy published in 2021, we have selected 10 for our annual “Best of” list, which we believe represents a kind of overview audio diary — capturing what we lived through, felt, and thought during the past 12 months.
Last week we included the first five; here are the final five of our curated list of podcasts that we think reflect the momentous year we’ve experienced. Of course, you can always find YOUR favorites by going directly to our podcast page.

A Constitution of Knowledge
Why can we no longer talk in good faith about a shared reality? Why do we suddenly have to define what we mean by “truth”? These are a few of the questions we discuss with journalist, author, and Brookings Institution fellow Jonathan Rauch.

America Is No Longer a Serious Nation
We have become a nation of narcissistic adolescents. We want what we want when we want it, and if we don’t get it, we stomp our feet at the ballot box. This according to author, journalist, and professor at the Naval War College Tom Nichols.
