“Unhappy is the land that needs a hero”*…

To the extent that evolutionary biologist and sociobiologist Robert Trivers has been in the news over the last decade, it has been for his entanglement with and highly-questionable defense of Jeffrey Epstein. But as Lionel Page reminds us, two decades before that– well before he could have known the execrable “financier”– Trivers made hugely important contributions to his field…

Steve Stewart-Williams announced… that Robert Trivers passed away.

Trivers was one of the most—perhaps the most—influential evolutionary biologists of the 20th century. His work should be much more widely known in social and behavioural sciences, in particular in economics, as Trivers’ intellectual approach is very much in line with a game theoretic understanding of social interactions.

It is hard to overstate the importance of his work. Einstein famously published four groundbreaking papers in 1905, a year often referred to as his “Annus mirabilis”, during which he revolutionised physics. Trivers might be said to have had a “Quinquennium Mirabile” for the five years between 1971 and 1976, during which he produced a series of ideas that revolutionised evolutionary biology…

[Page unpacks four of those contributions: Reciprocal Alturism, Parental Investment, Parental Offspring Conflict, and Self-Deception, each fascinating…]

… Trivers has been one of the most influential evolutionary biologists, and his papers are still worth reading today. His insights, published more than 50 years ago, are fascinating. They often align very well with economic theories of behaviour, and it is therefore regrettable that his ideas are not more well-known in economics, and in particular in behavioural economics.

A key feature of Trivers’ take across these contributions was to see that beneath the world of social interactions we observe, there are deep structures in terms of incentives that shape the game we play. Understanding these games and their structures helps us make sense of the seemingly endless complexity of human psychology and social dynamics. In several key contributions, Trivers helped lift the veil on the underlying logic of human behaviour…

As we linger over legacies, we might send material birthday greetings to a man who helped lay the groundwork for the field to which Trivers contributed, Ludwig Büchner; he was born on this date in 1824. A philosopher, physiologist, and physician, he became one of the leading exponents of 19th-century scientific materialism. Büchner was an early champion of Darwin’s theory of evolution, endorsing it within a decade of its first issuance, then did much to spread it by citing and building on it in his own books.

As far as we know, Büchner’s life was free of the scandal and conflict that plagued Trivers. He taught at the University of Tübingen and published dozens of books and papers. Later in his life he founded he “German Freethinkers League” (“Deutsche Freidenkerbund”) and served as a member of the second chamber of the Landstände of the Grand Duchy of Hesse as a representative of the German Free-minded Party from 1884 to 1890. He was the younger brother of Georg Büchner, a famous revolutionary playwright, and Luise Büchner, a women’s rights advocate; and he was the uncle of Ernst Büchner, inventor of the Büchner flask.

After completing this research, a definitive solution still remains unclear to me. We face a difficult paradox: combating extremism with equal measures risks becoming a form of radicalism itself, only perpetuating the cycle. The true challenge moving forward is finding ways to dismantle these rigid systems of thought without abandoning our own objectivity in the process.
