Key Takeaways 1. The biological ceiling: Classical hierarchy exploits evolutionarily ancient stress mechanisms — which physiologically degrades employees' cognitive capacity through what's known as "amygdala hijack." 2. Psychological safety isn't about being "nice". It's the baseline condition your prefrontal cortex needs to run complex analysis and actually learn anything. 3. Unbossing isn't ditching structure — it's a deliberate tradeoff: you're trading low coordination overhead (hierarchy) for higher adaptability and genuine engagement (self-management). Nothing is free. 4. The 2026 wrinkle: AI agents are absorbing more and more control functions — but the brain still tends to read an algorithm as the "alpha", which creates entirely new varieties of cortisol feedback loops.
