I’m often asked questions such as “Why are you blaming the kids? Isn’t it the parents’ fault?” (Or “the Boomers’ fault?” or “GenX’ers fault?”) This question makes two false assumptions: first, it assumes that all generational changes are negative; second, it implies that a single cause (such as parenting) can be identified for each change.

it’s not just parents, but technology, media, business, and education working together
Note:NON SOLO GENITORI

Yellow highlight | Location: 284
First, the two things must be correlated with each other. For example, we can see whether teens who spend more time on social media are more depressed. Second, the two things must change at the same time and in the correct direction. If social media use and depression both increase during the same years, one might cause the other.

2 Lo sforzo educativo ridimensionato SAGGIO



Lo sforzo educativo ridimensionato


THE CASE AGAINST GUILT: A PARENT’S GUIDE TO BEHAVIORAL GENETICS – Selfish Reasons to Have More Kids: Why Being a Great Parent is Less Work and More Fun Than You Think – Bryan Caplan

Punti chiave: La paura di essere giudicati come genitori pigri – Quanto conta il nostro sforzo educativo? Poco, meno di quel che pensiamo – La natura vince… alla lunga – Genetica comportamentale: studi su gemelli e adottati – La natura umana è flessibile – Natura, famiglia, ambiente non condiviso (libertà fortuna) – Salute, intelligenza, successo, voti, reddito, carattere, Felicità, autostima, valori, riconoscimento ai genitori, sesso, amore, divorzio, orientamento sessuale – Il test di Segan

This may sound discouraging. No parent wants to hear that his sacrifices have been in vain.

two kinds of families are special: Families that adopt, and families with twins.
Note:CIÒ CHE SERVE
Yellow highlight | Page: 40
there are two kinds of twins: identical and fraternal. Identical twins share all of their genes…Fraternal twins share only half of their genes…
Note:DUE TIPI DI GEMELLI
Yellow highlight | Page: 40
if identical twins resemble each other more than fraternal twins, the reason is probably nature.

twins who were separated and raised by different families.
Note:L’ESPERIMENTO PERFETTO
Yellow highlight | Page: 40
If identical twins raised apart are more similar than fraternal twins raised apart, the reason almost has to be nature. If twins raised together are more similar than twins raised apart, the reason almost has to be nurture.

The result is a new discipline—behavioral genetics
Note:È NATA UNA NUOVA DISCIPLINA
Yellow highlight | Page: 40
Identical twins are much more similar than fraternal twins—even when separated at birth—and their similarity often increases as they age.
Note:ESITO
Yellow highlight | Page: 40
By the time adoptees reach adulthood, however, this resemblance largely fades away.

Most twin and adoption studies focus on people raised in advanced Western countries in modern times…If a mix-up sent a Haitian baby to food-rich America, and an American baby to hungry Haiti, the effect on height could be massive…

NURTURE AND ENVIRONMENT ARE NOT THE SAME
Yellow highlight | Page: 42
No two people have exactly the same environment. Two children who live under one roof have different teachers and friends.
Note:L’AMBIENTE È UNICO
Yellow highlight | Page: 42
researchers equate “nurtured in the same way” with “were raised by the same people.”
Note:CONVENZIONE
Yellow highlight | Page: 42
Any feature of children’s environment that varies despite the fact that they were raised by the same people. Researchers call such features “unique environment” or “nonshared environment,”
Note:AMBIENTE ORIGINALE O NON CONDIVISO
Yellow highlight | Page: 42
Anything from peers, germs, and television to parental favoritism, dumb luck, and free will could qualify as unique environment.

Instead of picturing a two-way race between nature and nurture, picture a three-way race

The fact that genes don’t explain everything does not imply that family environment explains the rest.
Note:SPIEGAZIONI RESIDUALI
NATURE AND NURTURE: DIRECT VERSUS INDIRECT EFFECTS
Yellow highlight | Page: 43
If researchers report that genes affect income, for example, the reason might be that genes matter for intelligence, and intelligence matters for income.
EFFETTI DIRETTI E INDIRETTI…. PROBLEMA IRRILEVANTE?
Yellow highlight | Page: 43
Since researchers bundle together direct and indirect effects, their results are a lot stronger than they look. Suppose an adoption study finds that nurture doesn’t influence smoking. A parent could not reasonably object, “Right, but since peers influence smoking, and parents influence peers, I still matter.” The flaw in this argument is that a normal adoption study includes any and all indirect effects.

MEASURING NATURE AND NURTURE EFFECTS

The clearest measures come from a thought experiment I call “Switched at Birth”

if your counterpart in the thought experiment is in the 51st through 55th percentiles, I’ll call that a “small” effect. If he’s in the 56th through 65th percentiles, I’ll call that a “moderate” effect. Anything more I’ll call “large.”

THE PARENTAL WISH LIST: CAN PARENTS MAKE THEIR DREAMS COME TRUE?
Yellow highlight | Page: 45
you’d still prefer your kids to become healthy, smart, happy, successful, virtuous adults who share your values and appreciate..The underlying assumption is that parents have the power to grant their own wishes…
Note:LA LISTA
WISH #1: HEALTH
Yellow highlight | Page: 46
Parents pressure their kids to eat right, get fresh air and exercise, brush their teeth, and stay away from tobacco and drugs…The main rationale for health-related nagging is to instill healthy habits…

Parents don’t affect life expectancy. Major twin studies find no influence of family environment on life span.

Parents have little or no effect on overall health. There’s more to health than staying alive.

The most striking evidence on nature, nurture, and happiness comes from the Minnesota Study of Twins Reared Apart. Twins raised apart were more alike in happiness than twins raised together.

The same goes for self-esteem.
Note:STIMA

Unhappy adults like to blame their problems on their parents’ lack of love and support. According to the best evidence, however, both groups are wrong.

WISH #4: SUCCESS

Strangers often advise you to follow your dreams, but parents are more likely to tell you to get your head out of the clouds…Being a successful lawyer is more fun than being a failed actor….
