Il discernimento SAGGIO
La nostra scuola è costruita per i ritardati o i geni?
la situazione
- Grouping students of the same age in classes according to their abilities, i.e. tracking (National Association for Gifted Children)
- Accelerating students through the curriculum according to their readiness, ignoring age or grade level (A Nation Deceived)
- Using personalization software to replace a human tutor (How Khan Academy Will Help Find The Next Einstein)
- democratic equality (“education as a mechanism for producing capable citizens”)
- social efficiency (“education as a mechanism for developing productive workers”)
- social mobility (“education as a way for individuals to reinforce or improve their social position”)
TROPPO POCA DISEGUAGLIANZA?
La concorrenza su internet
Perché tanti monopoli? Suppose I am managing the incumbent firm X, and you want to enter the market with firm Y. In textbook economics, Y just has to copy what X does. But that does not work in the Internet context. Most people say that is because of network effects and lock-in, but I think there is a more important reason.
The problem with your copying me is that by the time you finish copying the current version, I will be two or three versions ahead of you

Massimo in 4
Conversations are typically limited to about four people, because four gives people the biggest bang for the buck

Cosa ha causato la recessione? Il fallimento di Lehman? No, la stretta monetaria

Adam Smith equivocato
Per molti, ancora oggi, non è un esponente del laissez faire. Sbagliato
The worst passages in Mr. Norman’s very good book, that is, come from accepting the assumption that markets are highly imperfect yet easily corrected—and that government, implicitly assumed to be capable of such delicate corrections, should step in. Such a plan runs against Mr. Norman’s own conservatism and Smith’s evolutionary thinking, which would favor spontaneous developments, not “policies” laid on in all directions by self-described experts.
“Far from always being choked back by rules and law, markets vividly illustrate how personal freedom and prosperity can be enlarged by them,” Mr. Norman claims. “Far from being intrinsically opposed, states and markets rely and benefit from each other.” Tell that to the farmer in Iowa facing retaliation from China and other countries for American tariffs. Tell it to the west-sider in Chicago excluded from employment in a new factory or a new grocery store by governmental restrictions that would have made Smith’s blood boil.

La storia con i se e con i ma
The correlational studies demonstrate that experts with strong theoretical commitments to a covering law and cognitive-stylistic preferences for explanatory closure are more likely to reject close-call Counterfactual that imply that “already explained” historical outcomes could easily have taken radically different forms.
