Divertente, ironico, dissacrante. Il penultimo capitolo, la geo ingegneria, è forse un po' noioso (oppure ho preteso troppo dal mio poor English affrontandolo in lingua originale).
Alcuni punti di vista decisamente anticonvenzionali lasciano sconcertati ma, temo, è tutto vero.
I sedili per proteggere i bimbi non funzionano, l'inquinamento genera il calore ma al contempo ci protegge, i pazienti muoiono perché i medici non si lavano le mani,..

The Driving Force Behind Levitt and Dubner’s Book “Superfreakonomics,”
“Superfreakonomics” is a collection of studies that were performed by various economists and analyzed by the authors. These studies seek to outline unexpected ways in which the individual or society as a whole responds to outside influences. The book also attempts to break down the reasons behind why people make the choices they do given certain circumstances, and how some data sets show those choices to be misinformed. More than that, as economists, Levitt and Dubner better inform you why specific social interactions occur and the motivation behind them. They force you to reconsider how you view the world and question why people behave the way they do.
At the outset, the authors disclaim that “many of [their] findings may not be useful, or even conclusive” (Levitt and Dubner, 2009). While this holds true for many of the extremely enjoyable excerpts within the book, this is beside the point. What this book really tries to achieve is to provoke thought and create interest in using the study of economics to provide insight into how social interactions are incentivized and how what you think to be true may actually be false based on unconsidered data. The authors also want you to really think about human nature and the expected behavior of people. Too often, it is easy for us to take information at face value and simply decide how we feel about a particular situation based on our own background and personal knowledge. Although we can often be right in doing this, many times the correct or simplest answer is not the most obvious one. It is in this complacency that we fail to see the world through the eyes of an economist, someone who uses data to show the hidden meaning in how the world works.
Whether you agree with the authors’ conclusions and analysis or not, some of their findings are eye-opening and at times mind-blowing. Examples such as how “a street prostitute is like a department-store Santa,” or why a group of Queens, New York residents stood idly by while a rape occurred right in front of their eyes introduce you to a reality that may surprise you (Levitt and Dubner, 2009). These concepts are laid out in a well-reasoned fashion, and are certainly thought-provoking, while simultaneously challenging the norms with which you would have considered the situations presented.
Throughout the body of work of “Superfreakonomics,” some of the stories feel on point and others do not. While the authors attempt to let the reader know that their theories are not the end of the story, some of the conclusions drawn feel forced and are often controversial at best, and misleading at worst. That does not make the book any less worthy of your time, but that fact must be noted and taken with a grain of salt before committing to what it is they are trying to accomplish with the book. If you dedicate yourself to reading this book with an open mind, the stories will be more insightful and have more of an impact. That being said, just because you are open to what Levitt and Dubner propose does not mean you have to agree with them. Even in disagreeing, the reasoning they use to make their points is powerful enough to allow you to draw some of the same conclusions they arrived at and may drive you to do your own research regarding any questions the authors left unanswered.
In reading this book, what really makes it worthwhile is the change that can occur in your own thought processes. “Superfreakonomics” truly challenges and alters your perception of the world and makes you see things in a different light. It amplifies your understanding of the issues discussed in the book in ways that other similar books do not. This book is highly recommended for anyone that believes there can be more than one side to every story.

Moltissimi anni fa, pochi giorni prima della morte del Grande Timoniere (quindi doveva essere la fine d’agosto o l’inizio di settembre del 1976), in viaggio alla volta della Sardegna con gli zii, ci fermammo a mangiare da quello che all’epoca era il più reputato ristorante di Castiglion della Pescaia. Mi pare si chiamasse Romano (non esiste più da tempo). Ci servì di secondo dei gamberoni, o delle mazzancolle, spettacolari, fritti con una spolverata di pan grattato. Chiedemmo il bis. Il secondo piatto faceva schifo, tanto che accusammo Romano di aver riutilizzato lo stesso olio.
I sequel, nei libri ancor più che nei film e nei ristoranti, sono in genere peggiori dell’originale. Penso che la ragione vada divisa, ma non in parti eguali, tra autore e lettore. Al lettore manca l’effetto sorpresa: sa già quello che si deve aspettare, i punti di forza del modo di scrivere e di argomentare dell’autore li dà per scontati, i punti deboli e le cadute di stile li trova ormai, più che irritanti, insopportabili. Ma le responsabilità principali le ha in genere l’autore che, spinto dal successo del libro precedente, dai diritti che gli intasano il conto bancario e dalle pressioni della casa editrice, ti propina more of the same. E questo more of the same è, magari, qualche cosa che (saggiamente) l’editor aveva espunto dal primo volume, o una compilation frettolosa di articoli pubblicati sui quotidiani sull’onda del successo.
L’unico capitolo che meriti di essere letto, secondo me, è il quinto, “What do Al Gore and Mount Pinatubo have in common?”

And yes, just as your grandmother always told you, practice does make perfect. But not just willy-nilly practice. Mastery arrives through what Ericsson calls “deliberate practice.” This entails more than simply playing a C-minor scale a hundred times or hitting tennis serves until your shoulder pops out of its pocket. Deliberate practice has three key components: setting specific goals; obtaining intermediate feedback; and concentrating as much on technique as on outcome [p. 61]
To build this fast, flexible, muscular, encyclopaedic system, Feied and Smith turned to their old crush:object-oriented programming. They set to work using a new architecture that they called “data-centric” and “data-atomic.” Their system would deconstruct each piece of data from every department and store it in a way that allowed it to interact with any other piece of data, or any other 1 billion pieces. [p. 72]
[…] “Are people really altruistic?” is the wrong kind of question to ask. People aren’t “good” or “bad”. People are people, and they respond to incentives. [p. 125]
To solve this puzzle, Semmelweis became a data detective. [p. 135]
[…] “McNamara is selling safety but Chevrolet is selling cars.” [p. 158]
Indeed, if we hadn’t played with Mother Nature by using ammonium nitrate to raise our crop yields, many readers of this book wouldn’t exist today. (Or they would at least be too busy to read, spending all day scrounging for roots and berries.) [p. 160]
Because cows – as well as sheep and other cud-chewing animals called ruminants –are wicked pollutants. Their exhalation and flatulence and belching and manure emit methane, which by one common measure is twenty-times more potent as a greenhouse gas than the carbon dioxide released by cars (and, by the way, humans). The world’s ruminants are responsible for about 50 percent more greenhouse gas than the entire transportation system. [p. 167: poco sotto spiega perché il movimento "locavore" peggiora il problema, dal momento che la fase di produzione pesa per l'80% delle emissioni e i piccoli produttori sono molto più inefficienti dei grandi, mentre la fase di trasporto pesa soltanto per l'11%; però, ci spiega Mary Roach in Gulp, gli erbivori non ruttano]

因此，宇宙中最強力的定律之一是『始料不及後果定律』(the law of unintended consequences)」 －p.30
大多數的施予，其實是經濟學家所謂的『非純粹利他』(impure altruism)，或『榮耀性利他』(warm-glow altruism)；你施予他人，並非只是因為你想幫助他們，也因為這樣的行為使你看起來有善心，或使你有好的感覺，或減少你的不安感覺。
「『始料不及後果定律』(the law of unintended consequences)是宇宙中最強力的定律之一。舉例而言，政府經常立法意圖保護最脆弱而需要被照顧者，但這些立法卻適得其反地傷害到他們。」 －p.200

Quite interesting, especially in the epilogue where monkeys were shown to exhibit all kinds of human behaviours after being taught the way of money. But overall the chapters have no logical connections, the subject matters are only lightly touched upon, and the book feels rather inconsequential on the whole.
