Good review. When I read someone describe themselves as rational I wonder who they’re trying to convince, and why.
The Rational Optimist
As part of my ongoing obsession with figuring out how we evaluate technology, I finally got around to reading Matt Ridley’s The Rational Optimist. It was an exasperating read.
On the one hand, it’s a history of the progress of human civilisation. Like Steven Pinker’s The Better Angels Of Our Nature, it piles on the data demonstrating the upward trend in peace, wealth, and health. I know that’s counterintuitive, and it seems to fly in the face of what we read in the news every day. Mind you, The New York Times took some time out recently to acknowledge the trend.
Ridley’s thesis—and it’s a compelling one—is that cooperation and trade are the drivers of progress. As I read through his historical accounts of the benefits of open borders and the cautionary tales of small-minded insular empires that collapsed, I remember thinking, “Boy, he must be pretty upset about Brexit—his own country choosing to turn its back on trade agreements with its neighbours so that it could became a small, petty island chasing the phantom of self-sufficiency”. (Self-sufficiency, or subsistence living, as Ridley rightly argues throughout the book, correlates directly with poverty.)
But throughout these accounts, there are constant needling asides pointing to the perceived enemies of trade and progress: bureaucrats and governments, with their pesky taxes and rule of law. As the accounts enter the twentieth century, the gloves come off completely revealing a pair of dyed-in-the-wool libertarian fists that Ridley uses to pummel any nuance or balance. “Ah,” I thought, “if he cares more about the perceived evils of regulation than the proven benefits of trade, maybe he might actually think Brexit is a good idea after all.”
It was an interesting moment. Given the conflicting arguments in his book, I could imagine him equally well being an impassioned remainer as a vocal leaver. I decided to collapse this probability wave with a quick Google search, and sure enough …he’s strongly in favour of Brexit.
In theory, an author’s political views shouldn’t make any difference to a book about technology and progress. In practice, they barge into the narrative like boorish gatecrashers threatening to derail it entirely. The irony is that while Ridley is trying to make the case for rational optimism, his own personal political feelings are interspersed like a dusting of irrationality, undoing his own well-researched case.
It’s not just the argument that suffers. Those are the moments when the writing starts to get frothy, if not downright unhinged. There were a number of confusing and ugly sentences that pulled me out of the narrative and made me wonder where the editor was that day.
The last time I remember reading passages of such poor writing in a non-fiction book was Nassim Nicholas Taleb’s The Black Swan. In the foreword, Taleb provides a textbook example of the Dunning-Kruger effect by proudly boasting that he does not need an editor.
But there was another reason why I thought of The Black Swan while reading The Rational Optimist.
While Ridley’s anti-government feelings might have damaged his claim to rationality, surely his optimism is unassailable? Take, for example, his conclusions on climate change. He doesn’t (quite) deny that climate change is real, but argues persuasively that it won’t be so bad. After all, just look at the history of false pessimism that litters the twentieth century: acid rain, overpopulation, the Y2K bug. Those turned out okay, therefore climate change will be the same.
It’s here that Ridley succumbs to the trap that Taleb wrote about in his book: using past events to make predictions about inherently unpredictable future events. Taleb was talking about economics—warning of the pitfalls of treating economic data as though it followed a bell-curve curve, when it fact it’s a power-law distribution.
Fine. That’s simply a logical fallacy, easily overlooked. But where Ridley really lets himself down is in the subsequent defence of fossil fuels. Or rather, in his attack on other sources of energy.
When recounting the mistakes of the naysayers of old, he points out that their fundamental mistake is to assume stasis. Hence their dire predictions of war, poverty, and famine. Ehrlich’s overpopulation scare, for example, didn’t account for the world-changing work of Borlaug’s green revolution (and Ridley rightly singles out Norman Borlaug for praise—possibly the single most important human being in history).
Yet when it comes to alternative sources of energy, they are treated as though they are set in stone, incapable of change. Wind and solar power are dismissed as too costly and inefficient. The Rational Optimist was written in 2008. Eight years ago, solar energy must have indeed looked like a costly investment. But things have changed in the meantime.
As Matt Ridley himself writes:
It is a common trick to forecast the future on the assumption of no technological change, and find it dire. This is not wrong. The future would indeed be dire if invention and discovery ceased.
And yet he fails to apply this thinking when comparing energy sources. If anything, his defence of fossil fuels feels grounded in a sense of resigned acceptance; a sense of …pessimism.
Matt Ridley rejects any hope of innovation from new ideas in the arena of energy production. I hope that he might take his own words to heart:
By far the most dangerous, and indeed unsustainable thing the human race could do to itself would be to turn off the innovation tap. Not inventing, and not adopting new ideas, can itself be both dangerous and immoral.
I wonder if the fact that Ridley owns a coal mine may have influenced his stance against renewable energy?
Good review, and spot on too. You cannot both be in favour of free trade and the exchange and intermingling of ideas as a route to progress and against the very trade agreements and social policies that permit these benefits.
