I was surprised and pleased to discover that the rock band Switchfoot have a song about the terrible cost to oneself of treating one's arguments as soldiers. It's called "The Sound in My Mouth". (Youtube link, with incorrect lyrics below it; better ones can be found at the bottom of this fansite page)

It focuses on the social costs rather than the truth-finding costs, but it's still well ahead of where I usually expect to find music.

"Perhaps the demographic collapse of advanced societies happens because the market supplies ever-more-tempting alternatives to having children, while the attractiveness of changing diapers remains constant over time."

The attractiveness of changing diapers does not remain constant over time. Modern diapers have little sticky tape on, and can be thrown out after a single use. Much better than washing cloth diapers and pricking yourself (or the baby!) attaching them.

For now, diapers remain a stinky mess. But we may yet invent a baby-washing, diaper-changing machine, without a sense of smell.
