Why do people sometimes do bad things? Why do some corporations take actions that risk the health of the planet, or even the end of civilisation? We may blame individual people for bad behaviour, bad philosophy, bad psychology, and so on, but from another level of analysis, we should expect that kind of bad behaviour, bad philosophy, and bad psychology to continue until destructive incentives are removed from our environment.
That's the analysis in this fascinating book by Kristian Rönn. The book provides excellent insight into why individuals keep pursuing objectives that end up harming the group in which they belong - and, in time, harming themselves too.
Rönn introduces the concept of "Darwinian demon", to describe destructive incentives, but he also postulates that "Darwinian angels" can arise, which lead individuals away from behaviours that cause group-harm and ultimately self-harm.
Along the way, Rönn explains the "group selection vs. individual selection vs. gene selection" controversy in evolutionary theory. He shows how, when matters are organised appropriately, selection happens on multiple levels in parallel. This has implications for humanity today.
The book analyses three fundamental races - the race for more resources, the race for more power, and the race for more intelligence. In our present world, each of these races is poised to bring humanity to catastrophe. Can we organise Darwinian angels in time?
Rönn reviews two ways in which destructive incentives can be changed: top-down control (which, alas, involves its own risks of catastrophe) and bottom-up decentralised adoption of reputation markets (which have their own drawbacks). The best solution may be a hybrid.
The solutions suggested in the book are unlikely to be sufficient, in the form presented, but they have the great benefit of encouraging a richer discussion of this important topic.
