"We are victims of the post-Enlightenment view that the world functions like a sophisticated machine, to be understood like a textbook engineering problem and run by wonks. In other words, like a home appliance, not like the human body. If this were so, our institutions would have no self-healing properties and would need someone to run and micromanage them, to protect their safety, because they cannot survive on their own....
By contrast, natural or organic systems are antifragile: They need some dose of disorder in order to develop. Deprive your bones of stress and they become brittle. This denial of the antifragility of living or complex systems is the costliest mistake that we have made in modern times. Stifling natural fluctuations masks real problems, causing the explosions to be both delayed and more intense when they do take place."
"So in complex systems, we should limit government (and other) interventions to important matters: The state should be there for emergency-room surgery, not nanny-style maintenance and overmedication of the patient—and it should get better at the former.E, na linha do aqui escrito ontem:
In social policy, when we provide a safety net, it should be designed to help people take more entrepreneurial risks, not to turn them into dependents. This doesn't mean that we should be callous to the underprivileged. In the long run, bailing out people is less harmful to the system than bailing out firms; (Moi ici: Recordo as ideias de um anónimo engenheiro de província em Dezembro de 2008 em "Como eu olho para crise") we should have policies now that minimize the possibility of being forced to bail out firms in the future, with the moral hazard this entails."
"Experts in business and government are always talking about economies of scale. They say that increasing the size of projects and institutions brings costs savings. But the "efficient," when too large, isn't so efficient. Size produces visible benefits but also hidden risks; it increases exposure to the probability of large losses.Como eu gosto disto, desta crença nos anónimos, nos amadores, no sentido mais belo do termo:
...
So we need to distribute decisions and projects across as many units as possible, which reinforces the system by spreading errors across a wider range of sources. In fact, I have argued that government decentralization would help to lower public deficits. A large part of these deficits comes from underestimating the costs of projects, and such underestimates are more severe in large, top-down governments."
"The great names of the golden years of English science were hobbyists, not academics: ... America has emulated this earlier model, in the invention of everything from cybernetics to the pricing formulas for derivatives. They were developed by practitioners in trial-and-error mode, drawing continuous feedback from reality. To promote antifragility, we must recognize that there is an inverse relationship between the amount of formal education that a culture supports and its volume of trial-and-error by tinkering. Innovation doesn't require theoretical instruction, what I like to compare to "lecturing birds on how to fly."A combinar com esta leitura de ontem "Seven characteristics of resilience":
"A common mistake is to assume that resilience means to recover as is, which is an over narrow definition. Often failure means rebirth, creating something new, recognising that the old is no longer sustainable..
...
Trying to prevent final collapse will just expend energy that you will need post-collapse to create something new and more sustainable. (Moi ici: Uma forma simples de explicar porque é que a austeridade em Portugal trouxe mais desemprego do que o que estava nas contas de todos, mais de uma década a pedir dinheiro emprestado para manter o emprego sobre-dimensionado em vários sectores da economia)
...
Dynamic re-organisation is greatly facilitated by modularity (or finely grained objects to reference my three heuristics of complex adaptive systems). That means small units that can combine and recombine, or even split off and reform with ease. Not so small that there is no coherence, but small enough for recombination.
...
Diversity and what I call requisite variety are key. Without diversity, and dare I say it contradiction, a system lacks the capacity to evolve quickly as it has too few things to build on. Conformity and consensus are the enemy of managing under conditions of uncertainty."
