Women in chess: role of innate-ability beliefs

5/30/2015 – What could the chess world learn from problems in the academic world, with regard to the participation of men and women? This "gender gap" is much bigger in physics or music composition than in molecular biology or psychology. A recent study found what matters is whether people believe you need to be brilliant to succeed in the field. Prof. Wei Ji Ma tells us what this study might mean for chess.

Women in chess: the role of innate-ability beliefs

By Wei Ji Ma

Gender differences in chess achievement were recently thrown into the spotlight once again, by a rather sardonic article by Nigel Short. Since the available statistical evidence indicates that gender differences in achievement are largely or entirely due to differences in participation (Chabris and Glickman, 2006, summarized here; Bilalic et al., 2009), the causes of this participation gap should be the primary focus of attention. Even if, like Short, one does not believe those studies, the participation gap might be of interest in its own right.

Much has been written about why far fewer women than men play chess, including on this site by Natalia Pogonina and Peter Zhdanov, (here, here, here and here) and most recently by Nisha Mohota. Although these articles have brought up highly plausible mechanisms, the debate would be aided by having more hard data available. In particular, wouldn’t it be great to have a large data set about the chess world in parallel with data about similar fields that have more female participation, so that possible causes of the participation gap can be tested for?

The bad news is that it is difficult to find many mind sports that are comparable to chess in terms of popularity and organization. The good news is that such a comparison can easily be made in academia, where different disciplines have widely different proportions of women. A detailed statistical study of gender disparity in academic fields in the United States appeared in January in the journal Science, and I believe that as a chess community, we can learn from it. The lead authors were Sarah-Jane Leslie from Princeton University and Andrei Cimpian from the University of Illinois at Urbana-Champaign; the latter was kind enough to fact-check what I write about his paper here.

“Hard” sciences such as physics and statistics on average have a larger gender gap than social sciences and humanities – no surprise there. However, this is only part of the story. According to 2013 data from the National Science Foundation in the United States, there is large variation within each category: whereas women earned only 19% of PhDs in physics and 18% in computer science, they earned no less than 54% of PhDs in molecular biology – amounting to gender parity. Within the humanities and social sciences, those numbers ranged from 78% in art history and 72% in psychology to a dismal 27% in philosophy and 28% in music theory and composition.

What, then, are the factors that cause not just the gender disparity between “hard” and “soft” sciences, but also the variation within each? The key claims of Leslie and Cimpian’s paper are:

  1. that fields vary in the degree to which its practitioners believe that innate ability (“genius” or “brilliance”) is required for success; and

  2. that society often promotes the notion that men have greater innate abilities than women.

If both claims are true, then the variation in the size of the gender gap can be explained relatively easily: women might be reluctant to enter or continue in fields where they believe they don’t have what it takes, or practitioners in those fields might discourage them to enter or continue.

The authors offer strong evidence for both claims. From a survey answered by 1820 faculty, postdoctoral researchers, and graduate students across the United States, they estimated the strength of the innate-ability beliefs in 30 academic disciplines. There was a clear negative correlation between the strength of the innate ability beliefs and the proportion of female PhDs (correlation coefficient of -0.60 across all 30 fields, with a p-value smaller than 0.001). The following figure from the paper shows the correlation, split out between “hard sciences” (A) and social sciences and humanities (B).

The more emphasis on brilliance, the lower the proportion of female PhDs. For example, mathematicians (whether male or female) widely believe that you have to be a genius to be successful, whereas neuroscientists (whether male or female) consider hard work to be more important; neuroscience produces a much larger proportion of female PhDs than mathematics. Philosophers believe that innate ability is critical, education scientists not so much; education produces a much larger proportion of female PhDs than philosophy. A follow-up paper by first author Meredith Meyer reported a very similar negative correlation between the proportion of female PhDs in a field and the innate-ability beliefs about that field held by people outside of academia.

It is important to keep in mind that beliefs about the importance of innate ability in a field are just that: beliefs. The degree to which they are justified is difficult to assess and was not part of this study. Another caveat is that correlation does not equal causation: it might be that innate-ability beliefs do not cause lower female participation. This concern was addressed by Cimpian and colleagues in a series of laboratory experiments. In one of these, the experimenters made up a story about a new science major being introduced at a university. If the study participants were told that this major required brilliance, then significantly fewer women were motivated to pursue it, whereas if they were told that it required hard work and dedication, there was no gender gap. This strongly suggests that there is a causal link between beliefs about brilliance being required and low female participation.

The authors performed a more detailed analysis in which they determined how important innate-ability beliefs were compared to other possible factors such as the number of hours worked per week, the selectivity of admissions, and the importance of abstract thinking versus empathy. None of these other factors came even close to the role of innate-ability beliefs in terms of accounting for the proportion of female PhDs.

As to the second claim of cultural stereotypes linking men but not women to brilliance, there is strong evidence from laboratory experiments. In one, the experimenter told children a short story about a “really, really smart person” at work. The experimenter then showed the child two pictures of men and two of women and asked the child to guess who this smart person was. Five-year-olds generally chose their own gender as smart (and thus showed no evidence of a stereotype), but six- and seven-year-olds started to show a bias towards choosing men more frequently than women. Where those prejudices come from is perhaps not surprising: parents google “is my son gifted?” 2.5 times as often as “is my daughter gifted?” Authors like Lisa Bloom, politicians like Jo Swinson, and even a campaign by Verizon Wireless have pointed out that girls get praised for their looks, while boys get praised for their smarts. The belief that mostly men are geniuses is further promoted by popular culture, from Good Will Hunting to House M.D., and persists among highly educated adults: on Ratemyprofessors.com, the word “genius” is used much more for male than for female professors. Objectively, there is no scientific basis for claiming that women are less brilliant than men; for example, in American schools, girls are 11% more likely to be in a gifted program than boys.

In short, in a field like physics or music composition, practitioners (men and women alike) believe that one needs to be a genius to succeed, and in society as a whole, women are considered unlikely to be geniuses. The disastrous consequences of these two belief sets combined are easy to imagine: women select themselves out because they don’t think they are suitable, interviewers and admission committees discriminate against women, or women in these fields drop out at higher rates due to the pressure of having to fight a stereotype (stereotype threat). In a schematic by Cimpian:

The strength of the Science paper stems from having data from many survey respondents and many academic fields, and it is does not seem a stretch to assume that its message also applies to chess, another institutionalized intellectual endeavor. Chess might be similar to physics, philosophy, and music composition: innate-ability beliefs are front and center in the ways chess players and society at large talk about chess. Chess prodigies are considered born, not made, and popular culture widely uses chess as a cue for genius. Leslie and Cimpian’s study would suggest that the primary reason why women are not motivated to pursue chess or are discouraged by others is that they or people around them do not believe they have the brilliance everyone believes to be needed for success in chess. (Again, this is regardless of the extent to which brilliance is truly required.)

Where to go from here? There are logically two possible starting points for improvement: the cultural stereotypes and the innate-ability beliefs. Of these, the latter might be easier to address than the former. In chess, László Polgár has been the leading warrior against innate-ability beliefs, arguing that hard work and good training are sufficient for success. Although his pedagogical experiment was by no means scientifically controlled, his message was an important one. In fact, the advice for educators offered by the authors of the Science paper has a very similar flavor:

If educators, academics, and administrators wish to increase the diversity of a particular discipline, our work suggests that they may wish to alter the messages they send regarding what is needed for success in the discipline. A brief summary of suggestions on how to begin to do this can be found here. In addition to potentially increasing diversity, a very impressive body of work by Stanford psychologist Carol Dweck and her colleagues reflects that everyone -- regardless of gender -- benefits from viewing success as requiring hard work, dedication, and effort, rather than simply being a matter of raw, inherent talent. Moving away from "brilliance required" cultures may thus have a range of beneficial effects. – From Gender Gaps in Academia, retrieved on May 2nd, 2015.

These pointers might be relevant for chess educators interested in addressing the participation gap in chess in a more fact-based manner.

ChessBase articles on the gender gap in chess

Women can compete
2/10/2005 – At the recent US Championship a historic event went almost unnoticed. Chouchanik Airapetian became the first woman ever to receive a gender neutral invitation to the event. "Shoushan" predicts that in five years a woman will win the overall US Championship!

The question of the week
7/28/2005 – Science, like chess, attracts bright people, and there are many more males in both fields. So can we conclude that men are smarter? Not necessarily, says Marilyn vos Savant in PARADE Magazine. "Chess was developed by males for intellectual sparring with other males. Maybe females simply don’t find the game as fascinating." Questionnaire...

Are men smarter than women?
8/9/2005 – Recently we reported on an article about science and chess attracting more men than women, and the possibility that this might be due to a difference in the general intelligence level of the genders. The questionnaire attached to the article brought an overwhelming result: neither gender is smarter. Interesting how the 50 personalities are ranked.

Sex Differences in Intellectual Performance
1/30/2007 – Is the disparity between women and men in the sciences the result of an innate difference in cognitive ability or the result of a social phenomena such as selective participation or discrimination? Chess is a good way to objectively study this question, since the rating system tracks players throughout their careers. A paper by two scientists reports on the results of such a study.

Women in Chess – a matter of opinion
9/21/2007 – The recently ended International Women's Chess Tournament in Baku was a great success, with sponsors and organisers promising further such tournaments in the future. Our reporter Zahir Ahmadov used the opportunity to conduct an informal questionnaire on the state of women's chess: are men better at the game, and if so why. Interesting reactions.

Do men and women have different brains?
6/30/2009 – In a recent thought-provoking article WGM Natalia Pogonina and Peter Zhdanov presented their views on the topic of why women are worse at chess than men. A number of our readers were unconviced: they think that efforts at "explaining" differences between the sexes only from environmental factors are doomed at the outset. Recent studies seem to support this. Feedback and articles.

Should we abolish women's chess titles?
10/14/2009 – Women make up about 10% of the World Chess Federation's estimated one million members. The caliber of the top female players is rising dramatically, yet FIDE persists in the "anachronistic and demeaning practice of awarding separate titles for women at lower levels of accomplishment." Time to drop gender-segregated titles for women, says Barbara Jepson in the Wall Street Journal.

When knowing is losing – gender factors in chess
7/9/2009 – Normally knowing your enemy is an advantage. Not so in chess games between the sexes. In a study published in the European Journal of Social Psychology Dr Anne Maass (et al.) pitted male and female players against each other via the Internet. Women showed a 50% performance decline when they were aware that they were playing a male opponent. Very thought-provoking!

Male chess players show elevated aggressiveness against women
8/12/2010 – Recent research at Stockholm University shows that equally strong male and female chess players employ different opening strategies. The males tend to play aggressive openings against female opponents of the same playing strength, even if it increases the probability of losing the game. That has to be classified as irrational behavior. Paper by Swedish researcher Patrik Gränsmark.

Gender differences in chess
1/9/2012 – A new and very commendable women's live rating list of top players is being maintained by the Russian chess news portal ChessPro. Fired by this list we did a little additional research to find out how many female players there are in the top 100 and top 1000. What would you estimate? And what are the possible reasons for the superiority of males in certain intellectual activities? Latest research.

Gender differences in chess – feedback and a new theory
1/30/2012 – We recently told you about a report on the gender differences in chess – why it is that there is just one woman in the top 100 players in the world, and just 2.2 percent in the top 1000, according to the FIDE rating list. Naturally we received a large number of more or less adamant opinions from our readers, which we now share with you, together with a pet idea of our own.

Do Women Have a Chance against Men in Chess?
3/8/2012 – As we know all too well: most of the strongest players in the world are male. In the past we have speculated on the reasons for this gender discrepancy, with vigorous reader participation. On International Women's Day Peter Zhdanov, who is married to a very strong female player, provides us with some valuable statistics, comparing men and women on a country-by-country basis. Eye-opening.

Explaining male predominance in chess
6/19/2014 – There are two theories to explain male predominance at the apex of intellectual achievement: some attribute it to some innate evolutionary ability differences, others to social factors of present-day society. Robert Howard of Sydney, Australia, has sent us the most profound and well-researched article we have seen on this subject – we urge everyone to read and ...

Chess gender debate in the international press
4/21/2015 – The latest issue of the Dutch magazine New in Chess carried an article entitled "Vive la Différence!". In it the former World Championship challenger Nigel Short provocatively claims that there are genetic reasons why men are more successful in chess than women. This two-page article went viral, was picked up by the international news services and generated a world-wide media storm.

Vive la Différence – the full story
4/22/2015 – Yesterday we reported on the extraordinary news storm that had broken out over an article, by Nigel Short, that appeared in the magazine New in Chess. Going through the follow-up stories and readers' reactions it became clear that many had not read the original article. So we asked the NIC publishers for permission to reproduce it in full. Now you can judge for yourself.

Women's chess in India – myths and facts
5/2/2015 – A week ago Nigel Short unleashed a storm in the international press with his article on the gender difference in chess. Now one of India's top female players, IM Nisha Mohota, has thankfully taken it upon herself to describe the situation in her country – where chess is not very attractive for women players. Nisha tells us what can and must be done to alleviate an unfortunate situation.

"Since the available statistical evidence indicates that gender differences in achievement are largely or entirely due to differences in participation"

What did Lasker say? If somebody disagrees with him in chess, he could just checkmate him.
In soft subjects, we don't have such easy refutations.
So mediocrities do mediocre papers, and we get statements like the above. The number of Ph.Ds in any subject is never a valid measure of anything, except the number of Ph.Ds. A more relevant metric is the quality and quantity of their research. In Physics and Math, men dominate, just as they do in chess.

@Supposedly -- "Why are we still talking about this?"

OK, I'll bite. Because We Ji Ma wanted to pad his CV with a worthless article?!
Supposedly Supposedly 5/30/2015 02:32
I agree.
I like how the diagram is shaped like a phallus too.
Exabachay Exabachay 5/30/2015 02:58
Read the article and then comment. The article and the results are very much common sense and are well-founded and valid. This is actually the best and most substantial article I've read on this matter.

Chess is for sexually frustrated people. It applies mostly to geeky guys than to women...

Chess is surely not like theoretical physics. But it could be like philosophy, and music composition. In physics it's not only intuition, but it has mathematical reasoning too(an extra step we should not overlook easily). In general, physicists do not stop after getting the solution intuitively, and they have an extra challenge of creating the mathematical explanation(or else it has no meaning). The discovery of Higgs Boson particle is a nice example. The idea of Higgs particle is in 1964(obviously using mathematical equations), and LHC confirmed the particle in 2013 !!!. So physicists are seeing nature using mathematical equations, and not (only) intuition. Einstein does not say with (only) intuition that "Gravity slows time", but he has given the world his "General relativity" equations and which nature the obeys !. Chess may not be compared with scientific fields, and the thinking process in scientific fields is different in general.

Not completely applicable to chess which has a number of other social factors (such as age variation) to deal with. Some of the factors Dr. Wei gives can be applied to chess, but there are so many other factors to control for that are not present in the higher sciences. Chess is more of a social activity as opposed to those hard professional subjects that he mentions. These subjects have to compete with other more palatable careers. In addition, it is bewilderment that men also represent the larger number of best chefs in the world. Why is that? Certainly not because of lack of numbers of women engaged in cooking. It may be more interesting to know WHY there are disparate numbers of participation rather than simply analyzing the numbers themselves.

Thank you Wei Ji Ma! This is the first article, since the issue first appeared, that is intelligent and SPECIFIC! The author doesn't jump to fast conclusions or make simplistic generalisations, but instead offers a very interesting perspective on the apparent gender gap. I, for one, am interested in this matter for two reasons mainly: 1) Human curiosity. 2) Fairness in Society!
Daniel Pi Daniel Pi 5/31/2015 04:09
I agree with parts of the conclusion, but the study he's discussing seems to be methodologically unsound. Are the sample sizes of PhDs large enough to produce useful results? For what variables are they controlling? I can imagine a lot of confounding factors and common causation. On its face, I am skeptical that the results of that paper are statistically sound...
