Episode notes
Cultural Software Explains Human Success
- Human cultural "software" lets us outsource cognition across generations, enabling rapid cooperative scale without bigger brains.
- Michael Muthukrishna ties this to four laws: energy, innovations that leverage energy, cooperation scale, and evolving rules that shape societies.
Energy Return Shapes Inequality And Cooperation
- Declining energy return on investment (EROI) reduces surplus available for broad cooperation and fuels rising inequality.
- Michael uses oil discovery rates (from 1:1000 to ~1:5) and the 1970s oil shocks as turning points that weakened workers' returns.
French Nuclear Power Enabled Barbecues On Strike Days
- France's heavy investment in nuclear created energy stability enabling frequent strikes and social bargaining while maintaining output.
- Michael recounts the French tram-track barbecue anecdote to show how abundance supports civic protest and leisure.
