Cooperation Is Not Just Kindness

This episode looks at the prisoner's dilemma through the lens of evolutionary biology, starting with a detail from a Nikkei Science article about vampire bats — specifically, how bats that share blood with hungry companions tend to receive help in return, while those that never reciprocate eventually find themselves abandoned.From there, it moves into how the same logic applies to business: two shops undercutting each other into zero profit, or a single act of betrayal for a few thousand yen that quietly closes off future work, referrals, and relationships that might have mattered most when things got hard.The episode draws on the concept of the iterated prisoner's dilemma — the idea that when the same parties meet repeatedly over time, cooperation becomes not just the generous choice, but the strategically sound one.It also touches on what evolutionary biology identifies as the three main drivers of cooperation, and what they share: all three point toward long-term survival rather than short-term gain.A quiet reflection on how life and business are not single transactions, and how "don't write self-destruct code into a long timeline" may be the answer that hundreds of millions of years of evolution quietly arrived at.
