Host: Pushkin Industries
Podcast Description: Cautionary Tales delves into true stories of human error, tragic catastrophes, and hilarious fiascos, offering lessons for adults through engaging narratives. In this episode, "The Man Who Solved Kindness," Tim Harford explores the intricate relationship between altruism, genetics, and human behavior through the lives of evolutionary biologist Bill Hamilton and mathematician George Price.
1. Introduction: A Funeral and Reflections on Altruism
The episode opens with Bill Hamilton, an esteemed yet obscure academic in the field of evolution, attending the funeral of his friend George Price in London, January 1975. Hamilton grapples with feelings of guilt, questioning if he could have prevented Price's tragic death. The attendees at the funeral include high-powered academics and homeless individuals, highlighting the diverse impact Price had on people from all walks of life.
Notable Quote:
"These unfortunate people must have really loved George Price," reflects Hamilton’s contemplation on the nature of Price’s relationships and altruism.

2. Bill Hamilton's Quest to Understand Altruism
As a young academic at Cambridge in the 1950s, Bill Hamilton became fascinated by altruistic behavior in animals—actions that benefit others at a personal cost. Traditional explanations attributed such behavior to the "good and pure" aspects of human nature, but Hamilton sought a more scientific understanding grounded in evolutionary biology.
Using examples like ground squirrels alarming others of predators—a risky behavior for the individual—Hamilton questioned how such traits could evolve if natural selection favors individual survival. His professors dismissed the complexity behind altruism, leading Hamilton to feel isolated in his pursuit to uncover the genetic underpinnings of such behavior.
Notable Quote:
"Natural selection works on individuals, not groups or species," emphasizes Hamilton’s foundational belief that individual survival drives evolutionary traits.

3. The Birth of a Revolutionary Idea: Hamilton's Mathematical Approach
Despite limited support and funding, Hamilton persevered in his research, developing a mathematical framework to explain altruism from the perspective of gene-level selection. His groundbreaking ideas, initially rejected by prestigious journals like Nature, found footing in the Journal of Theoretical Biology, setting the stage for future discourse in evolutionary biology.
Hamilton's core realization was that behaviors appearing altruistic could be explained by the underlying self-interested propagation of genes. For instance, if an acting individual shares genes with others benefiting from their altruistic act, the trait can spread within the gene pool.
Notable Quote:
"It's a branch of mathematics that Hamilton had never even considered," highlighting the novel approach Hamilton took in his research.

4. George Price: The Anti-Hero Mathematician
George Price, an unconventional figure with a tumultuous personal life, becomes central to Hamilton’s story. Price, who had a colorful career path—from the Manhattan Project to Bell Labs—struggled with personal relationships and health issues, leading to a series of professional disappointments.
In 1967, amid personal crises and a failed operation, Price sought rejuvenation by moving to London, hoping to rekindle his intellectual passion. It was during this period that he discovered Hamilton’s paper, which profoundly influenced his own thinking about altruism and genetics.
Notable Quote:
"I must be a crank," reflects Price’s initial doubt and isolation in his pursuit against established academic norms.

5. The Genesis of Price's Equation: A Miraculous Discovery
Intrigued and determined to challenge Hamilton’s theories, George Price embarked on understanding the mathematics behind altruism. Lacking formal training in biology, Price self-educated in covariance analysis, leading to the formulation of what is now known as Price's Equation. This equation provided a more generalized and elegant mathematical representation of gene-centric evolution, validating Hamilton’s initial theories.
Hamilton recognized the significance of Price’s work and the synergy between their ideas. The collaboration culminated in a joint publication in Nature, solidifying the importance of understanding altruism through genetic self-interest.
Notable Quote:
"It was a miracle," George Price mused upon the serendipitous convergence of his work with Hamilton’s theories.

6. Price's Altruistic Endeavors and Mental Decline
Embracing his newfound insights, Price adopted extreme altruistic behaviors inspired by a religious vision, despite being an atheist. He moved to London, using his insurance payout to support numerous homeless individuals, providing shelter and resources without expectation of reciprocity. This unbounded generosity isolated him further, straining his finances and personal well-being.
Despite initial successes, Price's altruism—rooted in a genuine desire to help—began to take a toll on his mental health. His inability to sustain his lifestyle led to a downward spiral, culminating in his eventual suicide in December 1974.
Notable Quote:
"Most of my possessions have been given away... I'll have to pick up a coat somewhere now, with winter coming on," illustrates Price’s complete dedication to altruism at the expense of his own welfare.

7. The Tragic Intersection of Genius and Mental Illness
George Price's story is a poignant exploration of how brilliant ideas can coexist with personal turmoil. His extreme altruism, inspired by both his mathematical discoveries and a perceived divine mission, underscores the delicate balance between intellectual pursuit and mental health. Price's tragic end serves as a cautionary tale about the potential perils of unchecked altruism and the human cost behind groundbreaking scientific advancements.
Notable Quote:
"When you’re broke and hungry, I doubt it very much," conveys the harsh reality of unreciprocated altruism in dire circumstances.

8. Reflections on Altruism: Genes vs. Pure Intentions
The episode culminates with a reflection on the nature of altruism. While Hamilton and Price's work illuminates the genetic motivations behind seemingly selfless acts, it challenges the traditional notion of altruism as purely benevolent. However, Harford posits that human rationality offers the potential to transcend genetic predispositions, allowing individuals to choose altruistic actions out of genuine empathy rather than mere genetic self-interest.
Notable Quote:
"When we feel an instinct to feed the hungry... maybe that's our selfish genesis, shaped by untold generations," encapsulates the central dilemma of understanding altruism through a genetic lens.
