Laszlo Polgar

Laszlo grew up determined to have a family, and a special one.

from Socrates to Einstein.

Yellow highlight | Location: 253

He decided that traditional education was broken,

the school system was frustratingly one-size-fits-all,

producing “the gray average mass,” as Laszlo put it.

Yellow highlight | Location: 262

For his first genius, Laszlo picked chess.

chess was suddenly pop culture.

Laszlo and Klara decided they would educate her at home

When she was seventeen, Susan became the first woman to qualify for the men’s world championship,

Yellow highlight | Location: 283

The Polgar sisters became “national treasures,”

Yellow highlight | Location: 284

In January 1991, at the age of twenty-one, Susan became the first woman to achieve grandmaster status

Yellow highlight | Location: 287

None of the sisters ultimately reached Laszlo’s highest goal of becoming the overall world champion, but all were outstanding.

Yellow highlight | Location: 291

Laszlo’s experiment had worked.

Yellow highlight | Location: 291

if his early specialization approach were applied to a thousand children, humanity could tackle problems like cancer and AIDS.

Like the Tiger Woods story, the Polgar story entered an endless pop culture loop in articles,

Gary Klein is a pioneer of the “naturalistic decision making” (NDM) model of expertise;

Yellow highlight | Location: 313

it frequently bred confidence but not skill.

Yellow highlight | Location: 314

He first began to doubt the link between experience and expertise

Yellow highlight | Location: 322

Kahneman marveled at the “complete lack of connection between the statistical information and the compelling experience of insight.”
Note:L intuito nn pagava

Yellow highlight | Location: 325

experience simply did not create skill in a wide range of real-world scenarios,

Yellow highlight | Location: 327

repetition did not cause learning.

Yellow highlight | Location: 327

Chess, golf, and firefighting are exceptions, not the rule.
Note:Conclusione di k

Yellow highlight | Location: 329

Do specialists get better with experience, or not?

Yellow highlight | Location: 330

Whether or not experience inevitably led to expertise, they agreed, depended entirely on the domain in question.

Narrow experience made for better chess and poker players and firefighters, but not for better predictors of financial or political trends,

Kahneman was focused on the flip side of kind learning environments; Hogarth called them “wicked.”

Expert firefighters, when faced with a new situation, like a fire in a skyscraper, can find themselves suddenly deprived of the intuition formed in years of house fires, and prone to poor decisions.

“Anything we can do, and we know how to do it, machines will do it better,”

Yellow highlight | Location: 360

“you can get a lot further by being very good in tactics”—that is, knowing a lot of patterns—“and have only a basic understanding of strategy.”

Yellow highlight | Location: 362

computers are tactically flawless

Yellow highlight | Location: 363

What if, Kasparov wondered, computer tactical prowess were combined with human big-picture, strategic thinking?

The captain and primary decision maker was Anson Williams, a British engineer with no official chess rating.

In traditional chess, Williams was probably at the level of a decent amateur.

Yellow highlight | Location: 384

As a teenager, he had been outstanding at the video game Command & Conquer,

grandmasters never had photographic memories after all.
Note:Conclusione

Yellow highlight | Location: 407

Rather than struggling to remember the location of every individual pawn, bishop, and rook, the brains of elite players grouped pieces into a smaller number of meaningful chunks based on familiar patterns.

Yellow highlight | Location: 411

Chunking helps explain instances of apparently miraculous, domain-specific memory, from musicians playing long pieces by heart to quarterbacks recognizing patterns of players in a split second and making a decision to throw.

Your restaurant server doesn’t just happen to have a miraculous memory; like musicians and quarterbacks, they’ve learned to group recurring information into chunks.

Chunking can seem like magic, but it comes from extensive, repetitive practice. Laszlo Polgar was right to believe in it.

Treffert documented the almost unbelievable feats of savants like pianist Leslie Lemke, who can play thousands of songs from memory.

savants reproduce “tonal” music—the genre of nearly all pop and most classical music—more easily than “atonal” music,

They do not merely regurgitate. Their brilliance, just like the Polgar brilliance, relies on repetitive structures,
