Can You Outsmart Your Genes? An Interview with Author Richard Nisbett

(Editor’s Note: inter­view­ing Richard Nis­bett, author of the excel­lent Intelligence and How to Get Itrecent book Intel­li­gence and How to Get It: Why Schools and Cul­tures Count, was in our To Do list. We then found that fel­low blog­ger David DiS­alvo was faster than we were and did a great job, so here we bring you David’s inter­view and take.)

While the debate over intel­li­gence rages on many fronts, the bat­tle over the impor­tance of hered­ity rages loud­est. It’s easy to see why. If the camp that argues intel­li­gence is 75 to 85 per­cent genet­i­cally deter­mined is cor­rect, then we’re faced with some tough ques­tions about the role of edu­ca­tion. If intel­li­gence is improved very lit­tle by schools, and if the IQ of the major­ity of the pop­u­la­tion will remain rel­a­tively unchanged no mat­ter how well schools per­form, then should school reform really be a priority?

More to the point, if our genes largely deter­mine our IQ, which in turn under­lies our per­for­mance through­out our lives, then what is the role of school? For some in this debate the answer to that ques­tion is sim­ply, “to be the best you can be.” But that seems lit­tle com­fort for those who aspire to “be” more than what their IQ cat­e­gory pre­dicts they will.

Those on the other side of this debate ques­tion whether hered­ity plays as big a role as the strong hered­i­tar­i­ans claim. And for the role it does play, they ques­tion whether hered­itabil­ity implies immutabil­ity. Hered­ity of height, for exam­ple, is about 90 per­cent, and yet aver­age height in sev­eral pop­u­la­tions around the world has been steadily increas­ing due to non-genetic influ­ences, like nutri­tion. If such a strong hered­i­tary trait can be rad­i­cally altered by envi­ron­men­tal factors–and height is but one exam­ple of this–then why is intel­li­gence different?

It is not, argues the camp that might best be described as intel­li­gence opti­mists. For them, the pes­simism that col­ors the strong hered­i­tar­ian posi­tion isn’t only dis­cour­ag­ing, it’s dan­ger­ous. Too much is hang­ing in the bal­ance for pes­simism about the poten­tial of our chil­dren to prevail.

Richard NisbettRichard Nis­bett is a cham­pion of the intel­li­gence opti­mist camp, and with his lat­est book, Intel­li­gence and How to Get It: Why Schools and Cul­tures Count , he has emerged as the most per­sua­sive voice mar­shalling evi­dence to dis­prove the heredity-is-destiny argu­ment. Intel­lec­tual advance­ment, Nis­bett argues, is not the result of hard­wired genetic codes, but the province of con­trol­lable fac­tors like schools and social environments–and as such, improv­ing these fac­tors is cru­cially impor­tant.

Improving the world, and one’s brain, at the same time

My wife and I just came back from an inspir­ing Gold­man Prize Award cer­e­mony, where seven grass­roots envi­ron­men­tal change­mak­ers were rec­og­nized for their work and resiliency, and shared their pas­sion and pur­pose with every­one attend­ing the event. We did hear too from Al Gore, Tracy Chap­man, Robert Red­ford, and the founder of the awards 20 years ago, Richard Goldman.

The BBC recently pub­lished an Op-Ed by Mr. Gold­man on the story behind the Awards them­selves: arti­cle Here. He explains how…

  • - “One morn­ing in 1989, as I sat with my daily break­fast and news­pa­per, I read about the most recent Nobel lau­re­ates and won­dered if there was a com­pa­ra­ble award for envi­ron­men­tal work.”
  • - “We asked a staff mem­ber at our foun­da­tion to do some research and he found that noth­ing yet existed to recog­nise envi­ron­men­tal work on an inter­na­tional stage, thus the Gold­man Prize was born.”
  • - “Our choice to focus specif­i­cally on grass­roots envi­ron­men­tal lead­ers was unique at the time.”

Mr. Gold­man, and the seven win­ners, are clearly help­ing improve the state of the world.

Now, the “state of the world” does include their very own brains — you may have seen this recent paper on how Vol­un­teer Pro­gram Pro­vides Health Ben­e­fits To Older Women

  • - “She and her col­leagues found that EC vol­un­teers showed greater improve­ments in mem­ory and exec­u­tive func­tion than those who did not par­tic­i­pate in the pro­gram. In fact, the older adults with the low­est base­line per­for­mance in these areas — those most at risk for health dis­par­i­ties — demon­strated the most sig­nif­i­cant gains.”
  • - “Both stud­ies high­lighted above show that every­day activ­ity inter­ven­tions (e.g., EC) can appeal to older adults’ desires to remain socially engaged and pro­duc­tive in their post-retirement years. Simul­ta­ne­ously, these activ­i­ties pro­vide mea­sur­able phys­i­cal and cog­ni­tive health benefits.”

Of course, those ben­e­fits do not accrue only for older adults (or just for women), but may help all of us grad­u­ally build Cog­ni­tive Reserves through the added nov­elty, vari­ety and challenge.

Learning about Learning: an Interview with Joshua Waitzkin

In 1993, Para­mount Pic­tures released Search­ing for Bobby Fis­cher, which depicts Joshua Waitzkin’s early chess suc­cess as he embarks on a jour­ney to win his first National chessJoshua Waitzkin cham­pi­onship. This movie had the effect of weak­en­ing his love for the game as well as the learn­ing process. His pas­sion for learn­ing was reju­ve­nated, how­ever, after years of med­i­ta­tion, and read­ing phi­los­o­phy and psy­chol­ogy. With this rekin­dling of the learn­ing process, Wait­zkin took up the mar­tial art Tai Chi Chuan at the age of 21 and made rapid progress, win­ning the 2004 push hands world cham­pi­onship at the age of 27.

After read­ing Joshua’s most recent book The Art of Learn­ing, I thought of a mil­lion top­ics The Art of LearningI wanted to dis­cuss with him–topics such as being labelled a “child prodigy”, bloom­ing, cre­ativ­ity, and the learn­ing process. Thank­fully, since I was pro­fil­ing Wait­zkin for an arti­cle I was for­tu­nate enough to get a chance to have such a con­ver­sa­tion with him. I hope you find this dis­cus­sion just as provoca­tive and illu­mi­nat­ing as I did.

The Child Prodigy

S. Why did you leave chess at the top of your game?

J. This is a com­pli­cated ques­tion that I wrote about very openly in my book. In short, I had lost the love. My rela­tion­ship to the game had become externalized-by pres­sures from the film about my life, by los­ing touch with my nat­ural voice as an artist, by mis­takes I made in the growth process. At the very core of my rela­tion­ship to learn­ing is the idea that we should be as organic as pos­si­ble. We need to cul­ti­vate a deeply refined intro­spec­tive sense, and build our rela­tion­ship to learn­ing around our nuance of char­ac­ter. I stopped doing this and fell into cri­sis from a sense of alien­ation from an art I had loved so deeply. This is when I left chess behind, started med­i­tat­ing, study­ing phi­los­o­phy and psy­chol­ogy, and ulti­mately moved towards Tai Chi Chuan.

S. Do you think being a child prodigy hurt your chess career in any way?

J. I have never con­sid­ered myself a prodigy. Oth­ers have used that term, but I never bought in to it. From a young age it was always about embrac­ing the bat­tle, lov­ing the game, and over­com­ing adver­sity. Grow­ing up as Read the rest of this entry »

Epigenetics: Nature vs. Nurture?

In yesterday’s inter­view with Michael Pos­ner, he says:

- “There is a grow­ing num­ber of stud­ies that show the impor­tance of inter­ac­tion between our genes and each of our envi­ron­ments. Epi­ge­net­ics is going to help us under­stand that ques­tion bet­ter, but let me share a very inter­est­ing piece of research from my lab where we found an unusual inter­ac­tion between genet­ics and parenting.”

- “Good par­ent­ing, as mea­sured by dif­fer­ent research-based scales, has been shown to build good effort­ful con­trol which, as we saw ear­lier, is so impor­tant. Now, what we found is that some spe­cific genes reduced, even elim­i­nated, the influ­ence of the qual­ity of par­ent­ing. In other words, some children’s devel­op­ment really depends on how their par­ents bring them up, whereas oth­ers do not — or do to a much smaller extent.”

Now check out this fas­ci­nat­ing arti­cle in the Econ­o­mist:Domes­ti­ca­tion and intel­li­gence in dogs and wolves | Not so dumb animals

- “Monique Udell of the Uni­ver­sity of Florida … won­dered whether learn­ing rather than evo­lu­tion explained his obser­va­tions. Her team there­fore worked with a mix­ture of pet dogs, dogs from ani­mal shel­ters that had had min­i­mal inter­ac­tion with peo­ple, and wolves raised by humans.”

Is Intelligence Innate and Fixed?

iq test, intelligenceGiven the recent James Wat­son “race and IQ” con­tro­versy, I took on to read Stephan Jay Gould’s clas­sic book The Mis­mea­sure of Man, in which he debunks IQ (and the under­ly­ing “g”) as mea­sure of defined, innate, “intel­li­gence”. Fas­ci­nat­ing read­ing overall, very tech­ni­cal in some areas.

The key take-away? In the last chap­ter, A Pos­i­tive Con­clu­sion, he writes that

- “Flex­i­bil­ity is the hall­mark of human evolution…In other mam­mals, explo­ration, play and flex­i­bil­ity of behav­ior are qual­i­ties of juve­niles, only rarely of adults. We retain not only the anatom­i­cal stamp stamp of child­hood, but its men­tal flex­i­bil­ity as well…Humans are learn­ing animals”

He then relates this story from T.H. White’s novel The Once and Future King

- God, he recounts, cre­ated all ani­mals as embryos and called each before his throne, offer­ing them what­ever addi­tions to their anatomy they desired. All opted for spe­cial­ized adult features-the lion for claws and sharp teeth, the deer for antlers and hoofs. The human embryo stepped forth last and said: Please God, I think that you made me in the shape which I now have for rea­sons best known to Your­selves and that it would be rude to change. If I am to have my choice, I will stay as I am. I will not alter any of the parts which you gave me…I will stay a defence­less embryo all my life, doing my best to make myself a few fee­ble imple­ments out of the wood, iron, and the other mate­ri­als which You have seen fit to put before me..” “Well done”, exclaimed the Cre­ator in delighted tone. “Here all you embryos, come here with Read the rest of this entry »

The Gene Delusion: IQ and the environment

An anony­mous reader of Andrew Sullivan’s blog writes a superb com­ment, repro­duced here:

One thing Wat­son and oth­ers for­get is that the brain is highly mal­leable based on envi­ron­ment. Although he is the father of DNA he knows very lit­tle about neu­ro­plas­tic­ity and neu­ro­ge­n­e­sis. Pre­vi­ously it was thought that the human brain was ‘hard­wired’ after a cer­tain age. This is not true. Not only is not true, but the human mind is capa­ble of adap­ta­tion but actual neu­ron growth even late in life. Ten years ago this was thought impossible.

Neu­ro­ge­n­e­sis and neu­ro­plas­tic­ity proves that a nur­tur­ing social and fam­ily set­ting shifts IQ, per­spec­tive, and emo­tional IQ. The so-called bell curve isn’t genetic. Oppressed Tibetans and Chi­nese eth­nic minori­ties –whose test scores soar in the United States and Canada– are 20–30 points lower in their home­land. That 20–30 points deficit is in the same range of a lot of groups that are attacked or threat­ened (Mus­lims in France, Chris­tians in Nige­ria, Blacks in Amer­ica). Con­versely when oppressed groups are removed from their envi­ron­ment their IQ, emo­tional health returns to a nor­mal rate, thus prov­ing that is NOT genetic.

It is plas­tic, shift­ing and based upon the environment.

That is why peo­ple Read the rest of this entry »

Brain Health Newsletter, February Edition, and Brain Awareness Week

We hope you are enjoy­ing the grow­ing cov­er­age of Brain Fit­ness as much as we are. Below you have the Brain Fit­ness Newslet­ter we sent a few days ago-you can sub­scribe to this monthly email update in the box on the right hand side.

In this post, we will briefly cover:

I. Press: see what CBS and Time Mag­a­zine are talk­ing about. Sharp­Brains was intro­duced in the Birm­ing­ham News, Chicago Tri­bune and in a quick note car­ried by the Amer­i­can Psy­cho­log­i­cal Asso­ci­a­tion news service.

II. Events: we are out­reach part­ners for the Learn­ing & the Brain con­fer­ence, which will gather neu­ro­sci­en­tists and edu­ca­tors, and for the Dana Foundation’s Brain Aware­ness Week.

III. Pro­gram Reviews: The Wall Street Jour­nal reviewed six dif­fer­ent pro­grams for brain exer­cise and aging, and the one we offer is one of the two win­ners. A college-level coun­sel­ing cen­ter starts offer­ing our stress man­age­ment one. And we inter­view a Notre Dame sci­en­tist who has con­ducted a repli­ca­tion study for the work­ing mem­ory train­ing pro­gram for kids with ADD/ ADHD.

IV. New Offer­ings: we have started to offer two infor­ma­tion pack­ages that can be very use­ful for peo­ple who want to bet­ter under­stand this field before they com­mit to any par­tic­u­lar pro­gram: learn more about our Brain Fit­ness 101 guide and Exer­cise Your Brain DVD.

V. Web­site and Blog Sum­mary: we revamped our home page and have had a very busy month writ­ing many good arti­cles. We also hosted two “Blog Car­ni­vals”- don’t you want to know what that means?
