If the Polgar's experiment is so accurate then, then it should be eminently repeatable across not just chess, but other domains. That is, if it's mainly nuture, not nature, people should be able to create other Polgars, if not Lebrons and Serena Williams and Stephen Hawkings.
If there's one thing that you absolutely do NOT need an experiment to discover, is that starting kids early, while affording them the possibility to become Lebron or Serena or Magnus, does not even remotely guarantee them to be in that category of excellence. If they don't have the talent, nothing you do will even get them close, even with lifelong training with the best teachers.
And do you think training kids with a GM will enable any typical kid to play blindfold chess at age 6? Seriously?!
Oh c'mmon man!
Struggled with math: MICHAEL FARADAY, CHARLES DARWIN, ALEXANDER GRAHAM BELL, THOMAS EDISON, JACK HORNER, E.O. WILSON and EINSTEIN ALBERT. To name a few.
Einstein was not bad at math.
Quote: How many Judit Polgar's has Laszlo been able to create outside of girls who had the same DNA?
Häää???????
Quote: How many players of even similar class have been created, credit with mainly using Laszlo's methods?
If I read the reports of the Polgar family correctly, the kids could not open their eyes without seeing a chess position in their home. Is that the method?
It's not in my eyes. The basic is intense training and creating a motivational surrounding in my eyes. But I'm very open to discussion in this point. If my point of view is right, we have a lot of players from the former soviet union with good training and teaching becoming a Kramnik, Kasparov, Karpov, ......
If something is supported by the Polgar case study, than it's the effect of intense training.
I don't draw that conclusion at all. I'm not saying intense training isn't helpful - it is, but I'm saying it won't make you a world champion without the talent.
I could surround my 5-year old daughter with chessboards, chess puzzles, etc. (she constantly comes and looks at chess with me on my computer) and she'll NEVER become even remotely what Judit could do at her age.
My own conclusion is my opinion on it, but I'd argue that the stories about Judit and her sisters have been misrepresented by Lazslo. Using Occam's razor, it's FAR more plausible and expected that Judit and her sisters were so strong because they shared special chess gifts in terms of DNA, and it was just sheer luck that Laszlo had 3 daughters that happened to overlap with his desire to examine parenting in chess.
With the genetic explanation, it's not only plausible but EXPECTED that you should not have other players of Judit's strength, even if Laszlo spreads his methods around, because people don't have the DNA-talent to achieve it.
And the argument that "well, parent's didn't go 'all-out' with Laszlo's methods" is also false. It's absolutely not an all-or-none effect, meaning that even if they didn't go all-out, he got plenty of press and attention that parents and academicians and scientists were looking at his stuff pretty seriously and considering it pretty seriously. Yet there was no chain of strong (even if not world-class strong) chess playing Polgar-method players from Laslzo, and no Laszlo-styled school of chess achieving outsized results by his early exposure methods.
What has been shown, is that yes, early exposure and good training helps people achieve their genetic potential and express their talent.
It does NOT support Polgar's attemption assertions that it was mainly because of heavy early exposure (and not talent/DNA) that enabled his daughters to become world champion level.
