Leonardo: I CD sono brutti

Questo post di Leonardo non è bellissimo (secondo me, ma forse è invidia, la mia), ma ha una frase geniale, che capovolge una famosa citazione di Arthur C. Clarke:

Any sufficiently advanced technology is indistinguishable from magic. [Profiles of the Future, 1961: una raccolta di saggi, non un romanzo]

Questo invece è Leonardo:

Questa cosa – che si potesse ascoltare musica senza il consumo di elettricità – i ragazzini non lo concepiscono: la sola idea che un oggetto possa riprodurre una canzone (anzi “suonare” una canzone, i dischi in vinile si “suonavano”) senza la preventiva pressione di un tasto ON, ha del magico, come ogni tecnologia desueta: dateci un altro secolo di microonde, e i nostri nipoti guarderanno con occhi sbarrati la pentola che bolle.

The Evolved Self-management System | Nicholas Humphrey su Edge

Abbiamo parlato di Nicholas Humphrey su questo blog qualche tempo fa, recensendo il suo Seeing Red, che avevo trovato molto interessante.

Ora Humphrey sviluppa su Edge una riflessione molto stimolante, secondo me: che l’effetto placebo “funziona” perché rimuove un “divieto” e “consente” una sorta di auto-cura, rassicurandoci che i suoi benefici eccedono i costi e che ci possiamo fidare del guaritore. Allo stesso modo, argomenta Humphrey, solo di recente l’ambiente culturale ha consentito alle personalità di uscire dai loro gusci e di sfuggire al conformismo, liberando enormi risorse di creatività.

Andate avanti da soli, cliccando sul link qui sotto. Ma poi tornate qui, perché ho un’altra cosa da mostrarvi.

The Evolved Self-management System | Conversation | Edge

Now, when people are cured by placebo medicine, they are in reality curing themselves. But why should this have become an available option late in human evolution, when it wasn’t in the past.

I realized it must be the result of a trick that has been played by human culture. The trick isto persuade sick people that they have a “license” to get better, because they’rein the hands of supposed specialists who know what’s best for them and can offer practical help and reinforcements. And the reason this works is that it reassures people—subconsciously —that the costs of self-cure will be affordable and that it’s safe to let down their guard. So health has improved because of a cultural subterfuge. It’s been a pretty remarkable development.

I’m now thinking about a larger issue still. If placebo medicine can induce people to release hidden healing resources, are there other ways in which the cultural environment can “give permission” to people to come out of their shells and to do things they wouldn’t have done in the past? Can cultural signals encourage people to reveal sides of their personality or faculties that they wouldn’t have dared to reveal in the past? Or for that matter can culture block them? There’s good reason to think this is in fact our history.

Go back 10 or 20,000 years ago. Eccentricity would not have been tolerated. Unusual intelligence would not have been tolerated. Even behaving “out of character” would not have been tolerated. People were expected to conform, and they did conform, because they picked up the cues from their environment about the right and proper—the adaptive—way to behave. In response to cultural signals people were in effect policing their own personality.

Alla fine del suo intervento su Edge, Humphrey cita un dibattito con Richard Dawkins in cui aveva difeso l’efficacia dell’effetto placebo a fronte dello scetticismo del suo interlocutore. Il video è un po’ lunare, ma interessantissimo. Il brain-storming di due grandi pensatori non convenzionali, pronti ad ascoltarsi e a cambiare idea.

Questa crisi è una crisi di bilancia dei pagamenti – FT.com

In un articolo – fondamentale, secondo me, per capire quello che sta succedendo – Martin Wolf del Financial Times argomenta che la crisi dell’eurozona è una crisi di bilancia dei pagamenti.

Questa tesi era già stata sostenuta – anche se all’epoca era passata pressoché inosservata – dal Rapporto annuale presentato dall’Istat il 26 maggio 2010:

Un terzo elemento, che contribuisce a spiegare la diffusione globale dell’impatto sull’economia reale e la caduta eccezionalmente veloce nelle esportazioni mondiali, risiede nell’entità senza precedenti raggiunta dagli scambi internazionali e dai contestuali squilibri nel conto corrente di bilancia dei pagamenti su scala mondiale (Figura 1.7). Negli anni precedenti la crisi si era determinata una crescita degli squilibri nel conto corrente di bilancia dei pagamenti, associata alla crescita del ruolo degli scambi internazionali (Figura 1.7). Gli avanzi di Cina, Giappone ed esportatori di petrolio, dall’inizio del decennio al 2008, sono passati approssimativamente dallo 0,5 al 2,0 per cento del Pil mondiale, mentre la gran parte dei disavanzi corrispondenti hanno riguardato le economie avanzate e, in particolare, gli Stati Uniti. Anche all’interno dell’area dell’euro (Uem) si è prodotta una polarizzazione crescente, ai cui estremi troviamo la Germania, che nel 2008 ha raggiunto un avanzo di quasi 170 miliardi di euro (circa 250 miliardi di dollari), e all’altro Spagna, Francia, Italia, Portogallo e Grecia, che insieme hanno totalizzato un disavanzo di oltre 255 miliardi di euro (circa 380 miliardi di dollari).

Merkozy failed to save the eurozone – FT.com

The German faith is that fiscal malfeasance is the origin of the crisis. It has good reason to believe this. If it accepted the truth, it would have to admit that it played a large part in the unhappy outcome.

Take a look at the average fiscal deficits of 12 significant (or at least revealing) eurozone members from 1999 to 2007, inclusive. Every country, except Greece, fell below the famous 3 per cent of gross domestic product limit. Focusing on this criterion would have missed all today’s crisis-hit members, except Greece. Moreover, the four worst exemplars, after Greece, were Italy and then France, Germany and Austria. Meanwhile, Ireland, Estonia, Spain and Belgium had good performances over these years. After the crisis, the picture changed, with huge (and unexpected) deteriorations in the fiscal positions of Ireland, Portugal and Spain (though not Italy). In all, however, fiscal deficits were useless as indicators of looming crises (see charts).

Now consider public debt. Relying on that criterion would have picked up Greece, Italy, Belgium and Portugal. But Estonia, Ireland and Spain had vastly better public debt positions than Germany. Indeed, on the basis of its deficit and debt performance, pre-crisis Germany even looked vulnerable. Again, after the crisis, the picture transformed swiftly. Ireland’s story is amazing: in just five years it will suffer a 93 percentage point jump in the ratio of its net public debt to GDP.

Now consider average current account deficits over 1999-2007. On this measure, the most vulnerable countries were Estonia, Portugal, Greece, Spain, Ireland and Italy. So we have a useful indicator, at last. This, then, is a balance of payments crisis. In 2008, private financing of external imbalances suffered “sudden stops”: private credit was cut off. Ever since, official sources have been engaged as financiers. The European System of Central Banks has played a huge role as lender of last resort to the banks, as Hans-Werner Sinn of Munich’s Ifo Institute argues.

If the most powerful country in the eurozone refuses to recognise the nature of the crisis, the eurozone has no chance of either remedying it or preventing a recurrence. Yes, the ECB might paper over the cracks. In the short run, such intervention is even indispensable, since time is needed for external adjustments. Ultimately, however, external adjustment is crucial. That is far more important than fiscal austerity.

In the absence of external adjustment, the fiscal cuts imposed on fragile members will just cause prolonged and deep recessions. Once the role of external adjustment is recognised, the core issue becomes not fiscal austerity but needed shifts in competitiveness. If one rules out exits, this requires a buoyant eurozone economy, higher inflation and vigorous credit expansion in surplus countries. All of this now seems inconceivable. That is why markets are right to be so cautious.

The failure to recognise that a currency union is vulnerable to balance of payments crises, in the absence of fiscal and financial integration, makes a recurrence almost certain. Worse, focusing on fiscal austerity guarantees that the response to crises will be fiercely pro-cyclical, as we see so clearly.
