The History of Bad Ideas: Short-Form Video

Today’s bad idea is one with a very recent history but also a long backstory: David talks to author and journalist James Marriott about what happens when the written word gets supplanted by video and when videos get shorter and shorter.

The History of Bad Ideas: Decadence

August 5, 2026 • 56 mins

The History of Bad Ideas: Political Leadership is What Counts

July 22, 2026 • 58 mins
Today’s bad idea is a pervasive political myth: the notion that what really matters at election time is political leadership.
