Summary
Overview
Tom Scott hosts a lively episode of Lateral with the Answer in Progress team - Sabrina Cruz, Melissa Fernandez, and Taha Khan - tackling fascinating lateral thinking puzzles ranging from internet governance by humming to dogs on spiritual pilgrimages. The trio works through questions about how decisions are made, scientific history, clown cars, and heartwarming Japanese cultural practices, showcasing both their problem-solving skills and entertaining chemistry.
How Internet Standards Are Decided by Humming
The team explores how the Internet Engineering Task Force makes consensus decisions through an unusual voting method. Rather than traditional voting, IETF members hum to indicate agreement or disagreement with proposals, creating an anonymous and spectrum-based decision-making process that has guided internet standards for decades.
- The internet is controlled by fiber optic cables, not electrical wires as initially suggested
- The Internet Engineering Task Force (IETF) makes decisions in conference rooms using humming as a consensus mechanism
- Humming provides anonymity - you can't easily identify who voted which way in a large group
- The volume and tone of humming helps gauge the strength of agreement without formal vote counting
" It's anonymous. You're right, Sabrina. But here's the thing. What if you're really tone deaf? What if you're like, yeah, that's clearly Jimbo over there. "
" In a big group of people, it is, I'm not going to say it's impossible to detect, but it is very difficult to have any sort of record that says this person voted this way because all you can hear is the hum "
Preserving the World's Oldest Continuously Inhabited City
A fascinating story about Erbil, Iraq's ancient citadel and the symbolic importance of continuous habitation. When authorities began renovating the 8,000-year-old site in 2007, they relocated 828 families but asked one family to remain to preserve Erbil's claim as the world's oldest continuously inhabited city, though the family later found life lonely surrounded by construction.
- The Citadel of Erbil has archaeological layers dating back 8,000 years
- In 2007, Kurdistan regional government relocated 828 families for restoration work
- One family, Rebwa Mohammed Qadir's, was asked to stay to maintain continuous inhabitation status
- The family was honored but found life impractical and lonely in the empty citadel during construction
" If that final family had left the citadel, then Errol would not be able to say that they were the longest inhabited city. "
" How good must it feel to be like, I got this, guys. They asked me to stay. "
