Can You Handle the Truth?

Yesterday Mike Murray started a new thread in the “All Things Chess” section of the USCF Forum. The title of his thread is a question, “Does chess develop transferable skills ?” (http://www.uschess.org/forums/viewtopic.php?f=23&t=21185&sid=fc8aa899349128eec2cc1414646786be) Mike begins his post answering the question by writing, “Evidently, not so much.” He then quotes from this blog by copying something I copied verbatim:

“…recent research into expertise has clearly indicated that, the higher the level of expertise in a domain, the more limited the transfer [of skills to other fields] will be… Moreover, reaching a high level of skill in domains such as chess, music or mathematics requires large amounts of practice to acquire the domain specific knowledge which determines expert performance. Inevitably, the time spent in developing such skills will impair the acquisition of other skills.”

Mr. Murray then gives a link to my post, and adds a link with which I was unfamiliar:
“see also” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4126200/

I would like to express my thanks to Mike Murray for drawing my attention to this paper.

Before deciding to write about what is currently known in regard to the question of whether or not chess is beneficial for children I took the time to read several papers pertaining to what has been learned by those who study these types of questions. These are the papers:

Educational benefits of chess instruction: A critical review

What put me on this path was the flap over what Malcolm Gladwell wrote in his book. “In Gladwell’s bestselling “Outliers” he discusses the “10,000-hour rule”: If you practice the necessary 10,000 hours you can reach the zenith of your field.” (http://www.salon.com/2014/07/15/is_malcolm_gladwell_wrong_scientists_debate_the_10000_hour_rule/)

In the same article Zach answers, “We found that, yes, practice is important, and of course it’s absolutely necessary to achieve expertise,” Hambrick told the Times. “But it’s not as important as many people have been saying.”

The article, Is Malcolm Gladwell wrong? Scientists debate the “10,000-hour rule: The argument between talent versus practices deepens with the release of a new study, by Sarah Gray, Tuesday, July 15, 2014. This particular article begins:

“A new study, published in the journal Psychological Science, is fueling the practice-versus-talent debate. The study was co-authored by Zach Hambrick, of Michigan State University, Brooke Macnamara, who is currently at Case Western Reserve University, and Rice University’s Frederick Oswald. According to the New York Times, this study is the “most comprehensive review of relevant research to date.”

“The paper, which looked at 88 different studies, covering a wide range of activities, from chess to music to sports, found that only 20 to 25 percent of a person’s ability — in music, sports and chess — came from practice. In academics, the Times reports, it is even lower; only 4 percent of a person’s academic ability came from practice. However, the authors note that academic skill was more difficult to measure, because it was tough to gauge how much people knew beforehand.”

The book by Malcolm Gladwell was a best-seller and the author, no doubt, made much money. Unfortunately for him, his theory has been refuted. Even so, their are many people who have not gotten the word. For example, I was sitting at a table in a Barnes & Noble with a chess board in front of me while reading a copy of the best chess magazine in the world, New In Chess, when an older fellow walked up and asked, “Putting in your 10,000 hours?” I asked if he were referring to Gladwell’s book and he answered in the affirmative. As he took a seat I told him Gladwell’s theory had been refuted. Having read the book, he was in disbelief. “The man would not have written the book if it were not true,” he said. Nothing I said could disabuse him of his belief. Fortunately, someone whom he knew arrived and he took his leave, but not before telling his friend that I was a “party pooper.” I have been called far worse…

This kind of thing happens all the time in our society. An example would be what the Bushwhackers said happened to Private First Class Jessica Dawn Lynch during the invasion of Iraq. Initial reports by the Bushwhackers said that before being captured and brutalized, PFC Lynch, in her best Rambo imitation, fired all the rounds in her weapon until the weapon was so hot it burned her hands, but still she continued, in great pain, to hold onto the weapon, using it to club Iraqi soldiers until there were so many of them she could no longer swing said weapon…or some such. I will admit to paraphrasing here, but you get the idea. The truth came out later, and I quote, “Initial official reports on Lynch’s capture and rescue in Iraq were incorrect. On April 24, 2007, she testified in front of Congress that she had never fired her weapon, her M16 rifle jammed, and that she had been knocked unconscious when her vehicle crashed. Lynch has been outspoken in her criticism of the original stories reported regarding her combat experience. When asked about her heroine status, she stated “That wasn’t me. I’m not about to take credit for something I didn’t do… I’m just a survivor.” (https://en.wikipedia.org/wiki/Jessica_Lynch#Further_reading) See The authorized biography, I Am A Soldier Too: The Jessica Lynch Story, by Pulitzer Prize-winning journalist Rick Bragg.” See also, “The truth about Jessica.” (http://www.theguardian.com/world/2003/may/15/iraq.usa2) People can still be found who will tell you all about the brave woman during the invasion of Iraq who made Rambo look like a wuss…

The lies the Bushwhackers told about former NFL star Pat Tillman are even more egregious, and the truth still has not been told to WE THE PEOPLE. I do not mean to single out the Bushwhackers. “Presidential aide Arthur Schlesinger has written that President Kennedy said just days before the assassination that Johnson was a man “incapable of telling the truth.” (See Robert F. Kennedy and His Times, page 655. I have taken this from the masterful work by Douglas P. Horne, Chief Analyst for Military Records, Assassination Records Review Board, “Inside the Assassination Records Review Board: The U.S. Government’s Final Attempt to Reconcile the Conflicting Medical Evidence in the Assassination of JFK – Volume 5.”)

Another example would be the prosecutor who, while the defandant is on the stand, looks the jury in the eye and says, “The defendant is obviously a scurrilous scumbag!” The public defender then leaps to his feet saying, “Your Honor, I most strenuously object.” At which time the judge says to the prosecutor, “The objection is sustained. Mr. Prosecutor. I cannot believe a man with your credentials would would say such a thing.” To which the prosecutor says, “Yes Your Honor. Forgive me. It will not happen again.” The judge then say, “That last remark will be stricken from the record and the jury will disregard the comment made by the esteemed prosecutor.”
When the trial ends and the jury is marched into chambers to decide the fate of the accused, the only question to be decided is which one will be chosen foreman. Once a foreman is chosen he will say, “Do we really need to spend any time voting? It is more than a little obvious the defendant is a scurrilous scumbag.”
Someone will mention the judge said to disregard the remark and will be turned on by the rest of the pack while the foreman says forcefully, “What the hell do you mean? The ESTEEMED prosecutor said the defendant was a scurrilous scumbag, and he would not have said it if it were not true!” Meanwhile the rest of the pack will nod in agreement, saying, “Uh huh, uh huh, right on, right on, right on.” The poor defendant will be lucky to have a show of hands before being declared guilty.

Debunking the Polgar Sisters Case

Mark Weeks writes the “Chess For All Ages” blog, and he is confused about the facts (http://chessforallages.blogspot.com/2015/02/confusion-about-facts.html) when it comes to the statement, “‘chess makes you smarter.” Many are confused when it comes to chess and intelligence because much has been written, but little understood, about the role chess has played in improving the “smarts” of a human being. Inquiring minds what to know so I asked for a little help from my friends in order to learn what is known by the most intelligent and learned people who study these kinds of questions. Numerous papers have been published concerning the issue and they are quite expensive. In my impecunious situation I would not have been able to read the papers except for the fact that friends in the world of academia gave me a helping hand. I profusely thank them for their kindness. I have read numerous papers recently, which made my eyes bleed…For the next several days I will share what I have learned with the chess community.

Judit Polgar retired from chess recently, bringing an end to the experiment conducted by the Polgar sisters father, Laszlo. Many women have written that if only there were more female chess players there would be more women in the top echelon of chess. For example, see “USCF President Ruth Haring’s “Numbers Game” (https://xpertchesslessons.wordpress.com/?s=USCF+President+Ruth+Haring%27s+%22Numbers+Game%22). Anjelina Belakovskaia is planning on a run for the USCF policy board and has written, ” I know that there is much more needs to be done and as a professional chess player myself (WGM), a business person, a Mom of 3 chess playing kids and a coach running Belakovskaia Chess Academy, I feel I can bring a lot to the table. From improving professional chess image, to attracting more girls into chess…” (http://www.uschess.org/forums/viewtopic.php?f=23&t=20700&sid=be60acd8a7253d079b536fc53c4dad14) She wants more girls in spite of the fact that the USCF’s own numbers show that girls drop out of chess at, or near, puberty. These women play, or have played chess, so they seem to think that if it was good for them, it will be even better for the game if many more girls play chess, and it will translate into many more elite female chess players. What I wanted to know is what the empirical evidence shows. I found the answer in a paper published in 2011 by Robert Howard of the School of Education, University of New South Wales, Sydney 2052, Australia, Does high-level intellectual performance depend on
practice alone? Debunking the Polgar sisters case.

“The Polgar sisters case often is cited as evidence that practice alone is key to chess skill and that
almost anyone can become a grandmaster (Ericsson & Charness, 1994; Forbes, 1992; Vinkhuyzen, van
der Sluis, Posthuma, & Boomsma, 2009). It has featured in the popular media, with the suggestion of
major educational implications (Colvin, 2008; Flora, 2005; Gladwell, 2008; Ross, 2006). As described
by Hearst and Knott (2009, pp. 136–137), “The Polgars’ father, Laszlo, was a teacher who believed that
there is really no such thing as innate talent or genius and that any reasonably normal intelligent person could achieve great success in a specialized field if he or she were given extensive and concentrated training in that field from an early age, starting particularly before they were six years old. . .”. The three sisters (born in 1969, 1974, and 1976) were raised in Hungary and home-schooled. They learned chess at a very young age and reportedly studied chess many hours a day (Forbes, 1992; Polgar & Truong, 2005). They excelled, two becoming grandmasters, and one still is the strongest-ever female player.
The Polgar case often is regarded as if it had been scrutinized carefully by expert reviewers and
reported in a scientific journal. But it never has been. If so submitted with the bare-bones facts cited by researchers (e.g. early starting ages, many daily practice hours, two becoming grandmasters), would the usual claims for it pass reviewer scrutiny?”

Examination method

“Here, the Polgar case was examined closely. Each sister’s expertise development was quantified
and compared with the other sisters’ development and with other groups and an individual. Two
data sets were used; longitudinal rating data from the international chess federation (FIDE) and data
from an online survey. Practice in chess is defined here as playing games and studying chess material
(Howard, 2009).
One comparison group was other players entering the international chess domain around the same
time; between the sisters’ entry dates of July 1980 and January 1987. The sisters had much more
practice on average because the other players mostly attended school, and there are no reports of
others having a Polgar-type upbringing. Most players do not study a lot. Charness, Tuffiash, Krampe,
Reingold, and Vasyukova (2005) reported a mean 6.3 h per week of “serious study” in chess players.
A second comparison was with an archetypal chess prodigy (ACP, born in 1990). He entered the
domain in January 2001, with a later start than the sisters (he reports taking up the game seriously at
age 8), gained the grandmaster title at age 13, and reached the number one ranking spot at age 19 in
2010. He lacked a Polgar upbringing and must have received much less practice, as detailed below.”

“The sisters started serious practice around the same age and studied about the same number of
hours daily, often being coached together (Polgar & Truong, 2005). Yet there are wide differences in
their rating development and their peak ratings.”

Conclusions

When examined closely, the Polgar case does not show that almost anyone can become a grandmaster
and that practice alone is key. From starting age to the late 1990s, the Polgars probably received
more practice than anyone ever has. Despite their much greater practice levels, two sisters’ peak ratings
are quite comparable to those of other players first on the list around the same time and to those
of eight surveyed and much less practiced grandmasters, and are well below that of less-practiced
ACP. If only practice and an early start were important, there should have been little difference among
them in their rating trajectories and peak ratings. All should have made the top ten and they should
have had a lasting stranglehold on the open world championship. A plausible alternative account is
that the Polgars have much natural talent for chess, one sister has more than the others, and ACP has
more than all three. No claim is being made here that the data presented show the existence of natural
talent, only that this interpretation is plausible.
The present study has limitations. It was not possible to directly survey the Polgars or ACP nor
to administer any tests to them. One might argue that some kind of practice really was key, that
training methods have improved and this somehow accounts for the results, or that everyone in the
present study on the list from 1980 to 1987 really had a Polgar upbringing. One could argue that too
many variables are confounded, or that ACP received some very special type of practice. Nature and
nurture are notoriously difficult to separate and there is no claim that they were separated here. Such
objections are irrelevant to the present purposes of demonstrating that an interpretation of the Polgar
evidence that invokes natural talent is plausible. In conclusion, the Polgar case does not stand up to
the claims often made for it.”
