Summer 2007: Internship with Baldwin Brothers

Natural Capital Institute

The Marion Institute has helped to sponsor some groundbreaking work in the world of Socially Responsible Investing [SRI]. Through the collaboration of Baldwin Brothers Inc. [BBI], Natural Capital Institute [a socially responsible investing research organization founded by Paul Hawken], Investors' Circle [IC], and The Rudolf Steiner Foundation [RSF] a new set of criteria for identifying and screening corporations that truly promote social and ecological change has been developed. Natural Capital Institute has performed in depth research on the existing SRI universe in over 600 mutual funds from around the world.

The results of this research can be viewed at www.responsibleinvesting.org where you will find the first comprehensive and queryable landscape of SRI. The report illustrates how the SRI industry has failed to respond to people who want to invest with conscience and what can be done to change it. You can also download the report here .
[PDF format, 5mb, requires Acrobat Reader 5.0 or later]
.

Visit the Responsible Investing database to unveil some of the findings from the report. Both will show you current portfolio practices, global fund allocations and how the industry should better respond to people who want to invest with conscience and purpose.

Although the SRI mutual fund database developed by this collaborative project can be useful for investors, NGOs, researchers and fund managers, the group’s primary concern was to address the following questions:

  1. Are the terms “socially responsible investing” or “social investing” so broad
    as to have little meaning? In other words, are the screening criteria and language employed by the SRI community adequate to express the scope and complexity of current business models as well as the problems facing humanity?
  2. Do SRI mutual funds play an important role in changing corporate practices?
    Or do they end up accomplishing the opposite purpose, serving as marketing tools used to appease investor sentiments and greenwash corporations?
  3. Should return on SRI funds be benchmarked against mainstream stock indices that are comprised of corporations that do not meet the same standards on social and environmental issues? Or should they be compared to companies with the highest standards of responsibility and reporting?
  4. For that matter, is there a socially responsible rate of return and if so how
    would it be determined?

Our research is ongoing as we zero in on the answers to these questions. Paul Hawken’s report addresses many of these issues but also raises many more.

Natural Capital Institute was founded by environmentalist and businessman Paul Hawken. He is author of six books including The Ecology of Commerce, The Next Economy, Growing a Business, and Natural Capitalism: Creating the Next Industrial Revolution. He founded and co-founded several companies including Smith & Hawken, Metacode, Groxis and several natural food companies that relied solely on sustainable agricultural methods.

"Marion Institute provides support and insight to emerging initiatives that make a profound difference in the world. Their work does not show up at the head of the parade, but is often the reason there is a parade at all. The Institute shows up early and presciently to bring forth the most innovative people and projects in the world."

Huang Wei Jia

Prof. Huang spoke about his education/background and what he did during the cultural revolution in class this Wednesday. I was really amazed.

Well, he'd just finished high school when the cultural revolution started. He worked in a factory for a while at this time when teachers that had spoken up about improving society were demoted. He started writing dictionaries with one such academic. That teacher asked Prof. Huang if he wanted to learn... in the three years, the teacher taught Prof. Huang secretly, until they were discovered. I don't know what happened as a consequence, but Prof. Huang started university when they reopened. After that, he taught for some years, married Prof. Ao and moved to America, where she went to get her graduate degree. For some years, he worked in a restaurant alongside doctors and engineers. He has since gone on to teach ancient Chinese at many universities, and has many books to his name.

He says that in those three years that he studied in secret, he learned far more than he did in university. He describes himself as a very lucky man to have been able to learn such treasure.

It has been a pleasure for me to be in his class this semester. He is such a cheerful man and he knows so many stories. Being in his class has afforded me a greater appreciation for the Chinese language.

E-mail to Mrs. Colasanti on Vaccination and Autism

Caution: Long e-mail. As a consolation, research has shown that children of better-educated mothers are healthier (citation needed :) )

Dear Mrs. Colasanti,

After talking with you on the phone the other day, I decided to look into the link between autism and vaccines. As I had expected to find, studies have show that there is no causal link between the two. In fact, if you use google to search "autism vaccine" most of the sources that say that there is a link base their information on sloppy investigative journalism. If you use Google scholar (which only searches research through citations, authenticating the research), you will find articles like the one I've listed below. Often what the media does is interview parents of children with autism... while scientific researchers observe trends and do statistical analyses. You mentioned that one out of 150 children have autism. Below I've copied an article published by USA today which has as its catchy title "Autism disorders affecting 1 in 150." This is higher than earlier estimates of 1 in 166. Below that I've attached an abstract from a reputable medical journal (JAMA Journal of the American Medical Association).

This is how vaccines work:
1. There is an infectious disease that causes pain and suffering (the vaccine suspected in the autism case is the MMR (measles, mumps, and rubella) vaccine which 6 years ago contained mercury compunds)
2. There are always people with compromised immunity, so some people will not get vaccinated
3. If these people get sick, and others around them are vaccinated, the disease is confined to that person
4. If the community is not vaccinated and someone from the community gets the disease, we have a big problem
5. Now, with increased travel between countries, this is even more the case.

Dangerous thinking:
1. There is no scientific evidence whatsoever (even statistically... meaning that between surveys of children not vaccinated vs. vaccinated there is no significant difference in number of autism rates) that vaccines cause autism
2. Autism rates are apparently increasing (this is expected because we're getting better at diagnosing autism.. but sure, autism is probably increasing, though most likely not at such an alarming rate)
3. So, now people are looking for reasons for the increase in autism rates. This is very important, because we really don't want more children to develop autism if it is preventable. However, IT IS EXTREMELY DANGEROUS TO BLAME VACCINES and discourage parents from having their children vaccinated. (Please see the last article on whooping cough/pertussis in Boston.)
4. I feel sorry for your friend whose child is autistic...
5. But think about it this way, the reason that the vaccine is important for children is because children have weaker immune systems. It is likely that parents unknowingly transmit virulent strains of diseases to their children because of this.


Autism disorders affecting 1 in 150
http://www.usatoday.com/news/health/2007-02-08-autism_x.htm
The number of children who have an autism disorder — as many as 1 in every 150 — is significantly higher than previously thought, according to a new federal report being billed as the most complete assessment to date.

Earlier estimates placed the rate at 1 in 166 children. But Catherine Rice, lead author of the analysis released Thursday by the U.S. Centers for Disease Control and Prevention, says the previous estimates were based on smaller studies, some from other countries, using different study methods.

The largest U.S. study of childhood autism to date has found that about 1 in 150 have the disorder -- a higher prevalence than previous national estimates, the Associated Press reports.

The autism rate was about 6.6 per 1,000 in the new study, which is based on data from 2002. The report was released today by the U.S. Centers for Disease Control and Prevention. Last year, the agency had estimated the rate was about 5.5 in 1,000.

The study does not, however, definitively answer whether autism is increasing. "We can't make conclusions about trends yet," because the study's database is too new, said Catherine Rice, a CDC behavioral scientist who was the study's lead author.

In materials posted online by CDC, the researchers write that: "A common explanation for increases ... over time has been that changes have occurred in the level of community and professional awareness about the symptoms" and that autism diagnoses are being applied to a wider range of symptoms.

Advocates for people with autism say the results should help them push for more services. The findings may further stoke the impassioned debate over causes: Some blame thimerosal, a mercury-based preservative that was used in infant vaccines up until six years ago. Scientists concede that they don't know the cause but say the science doesn't support a link to vaccines.

For the new CDC report, researchers drew on information gathered in 2000 and 2002 by a multistate surveillance network on 8-year-olds who were identified as having an autism spectrum disorder (ASD). The category includes autism, PDD-NOS (pervasive developmental disorder not otherwise specified) and Asperger's disorder. All are marked by problems with language and communication and often are accompanied by repetitive or unusual behaviors. ASDs begin before age 3 but may not be diagnosed until later.

Researchers focused on 8-year-olds because most children with such disabilities will have been identified by that age, Rice says.

The 2000 study, which examined children who were born in 1992, involved sites in six states and 1,252 children with ASDs. The prevalence averaged 6.7 children out of every 1,000.

The 2002 study, which focused on children who were born in 1994, involved 2,685 with ASDs at sites in 14 states and found that autism prevalence ranged from a low of 3.3 in 1,000 children in Alabama to 10.6 in 1,000 in New Jersey. The overall average was 6.6 in 1,000 children, or about 1 in 150.

Estimates differ because ASDs vary and some states have better diagnosis and tracking, Rice says.

Peter Bell, president of Cure Autism Now, says the report is "confirmation of our worst fears, and that is that autism is on the rise. Every two or three years, we're given an estimate that is higher than the previous one."

CDC Director Julie Gerberding said in a statement that it's still unknown whether there's an actual increase in autism or just better studies. "We do know, however, that these disorders are affecting too many children," Gerberding said.

States facing rising autism rates have struggled to provide services. Rice says the new information can be used by communities to help plan for the future needs of these children. "We know the best outcomes come when kids are identified early," Rice says.

The revised estimates will "increase awareness and hopefully get legislation to follow that will give services to those with autism," says Marguerite Colston of the Autism Society of America.



Association Between Thimerosal-Containing Vaccine and Autism

Anders Hviid, MSc; Michael Stellfeld, MD; Jan Wohlfahrt, MSc; Mads Melbye, MD, PhD

JAMA. 2003;290:1763-1766.

Context Mercuric compounds are nephrotoxic and neurotoxic at high doses. Thimerosal, a preservative used widely in vaccine formulations, contains ethylmercury. Thus it has been suggested that childhood vaccination with thimerosal-containing vaccine could be causally related to neurodevelopmental disorders such as autism.

Objective To determine whether vaccination with a thimerosal-containing vaccine is associated with development of autism.

Design, Setting, and Participants Population-based cohort study of all children born in Denmark from January 1, 1990, until December 31, 1996 (N = 467 450) comparing children vaccinated with a thimerosal-containing vaccine with children vaccinated with a thimerosal-free formulation of the same vaccine.

Main Outcome Measures Rate ratio (RR) for autism and other autistic-spectrum disorders, including trend with dose of ethylmercury.

Results During 2 986 654 person-years, we identified 440 autism cases and 787 cases of other autistic-spectrum disorders. The risk of autism and other autistic-spectrum disorders did not differ significantly between children vaccinated with thimerosal-containing vaccine and children vaccinated with thimerosal-free vaccine (RR, 0.85 [95% confidence interval {CI}, 0.60-1.20] for autism; RR, 1.12 [95% CI, 0.88-1.43] for other autistic-spectrum disorders). Furthermore, we found no evidence of a dose-response association (increase in RR per 25 µg of ethylmercury, 0.98 [95% CI, 0.90-1.06] for autism and 1.03 [95% CI, 0.98-1.09] for other autistic-spectrum disorders).

Conclusion The results do not support a causal relationship between childhood vaccination with thimerosal-containing vaccines and development of autistic-spectrum disorders.

Whooping cough makes a comeback

It sounds like something straight out of Dickens, closer to 1804 than 2004 -- a rattling, breath-robbing, rib-cracking cough, symptoms that linger for months, loss of sleep and weight.

The diagnosis -- pertussis, better known as whooping cough. At one time, public-health specialists had figured it was destined for extinction in the United States, just like polio and smallpox. But it's still here, six decades after vaccinations for the bacterial illness became routine -- a testament to the hardiness of infectious diseases.

"The bad news is that this disease is not gone," said Dr. Ken McIntosh, an infectious-disease specialist at Children's Hospital Boston. "I certainly have seen people with it, and they're miserable. And they're making everybody else in their lives miserable, and they're quite contagious. So it's not a nice disease to have."

The Centers for Disease Control and Prevention received reports of 11,647 cases of pertussis last year, compared with 1,707 in 1980 -- when the disease seemed to be dying out.

So, what explains the upsurge? And is it a true increase -- or a reflection of better reporting and testing?

Years ago, when pertussis was pervasive, children were regularly exposed and developed natural immunity.

"When the vaccine was licensed in the late 1940s and early 1950s, we saw a real drop in pertussis," said Dr. Susan Lett, medical director of the immunization program at the state Department of Public Health. "That was because all the adults at that point had had pertussis as kids, and their children were getting vaccinated, and so we saw a steep decrease."

In effect, the bacteria had no easy targets left.

But as the vaccine came into wider use, an important shortcoming was identified: The shot's effectiveness wanes within five to 10 years.

"What happened was that people at that time were so much in appreciation of the benefits of the vaccine that they did not think about the limitations," said Dr. Trudy Murphy, a medical epidemiologist in the CDC's National Immunization Program.

Doctors considered giving adolescents and adults another round of shots, but it turned out that side effects from the vaccine were amplified in older recipients. So that ceased to be an attractive option.

The result: Even though millions of US children have been immunized against whooping cough, the eroding effectiveness of the shot leaves them vulnerable to infection as they enter adolescence.

And, with the passage of time, there are fewer and fewer living Americans who were exposed to the bacteria when it was commonplace, meaning fewer people have natural immunity. The consequence, Lett said, is a "growing pool of susceptibles" -- more people whom the bacteria can successfully attack.

But McIntosh said the reported increase more likely reflects doctors being diligent about alerting health authorities to outbreaks, as well as improvements in laboratory tests used to confirm the disease.

"People are recognizing it more," McIntosh said, "and that's a good thing."

Nowhere is it recognized more than in Massachusetts. The state recorded about 1,700 cases of whooping cough last year -- one of every seven cases reported in the nation.

That doesn't necessarily mean we have more cases here. It's more likely proof of the state's aggressive testing for the disease, which began in the 1980s.

When pertussis kills, which is rare (19 Americans died in 2003), its victims are almost always infants.

Babies start getting immunized against pertussis when they are 2 months old, with another shot at the age of 4 months, and a final inoculation at 6 months.

"So what we really worry about is the 16-year-old who has pertussis, and it's unrecognized, and then the teenager baby-sits an infant younger than 6 months," said Dr. Alfred DeMaria, the state's director of communicable disease control.

Infants are especially susceptible -- and can become far sicker -- because their capacity to battle disease has yet to mature.

In anyone, whooping cough can cause significant discomfort, with dramatic bouts of coughing interfering with sleep and producing fits of vomiting.

And the effects are persistent: Studies have shown that 62 percent of adults with pertussis are still coughing three months after symptoms first appear.

Two drug companies -- GlaxoSmithKline and Aventis Pasteur -- have developed booster shots that target pertussis, along with diphtheria and tetanus. Last month, Glaxo sought US Food and Drug Administration approval for its product, and Aventis executives said they intend to apply for a license for their booster within a few weeks.

The new formulations are less potent than the shots given to infants, and drug company trials suggest they don't deliver the side effects that doomed earlier boosters.

"It is so important to express to people the importance of vaccination," said Lisa Rae, whose son, Kyle, contracted pertussis as an infant in suburban Philadelphia. "I remember stories my Mom told us about whooping cough. This wasn't anything we ever expected."

Meeting with Joan Kaufman

I met with Prof. Kaufman yesterday. The work that she has done is really quite amazing. Among other things... she mentioned a few projects that she's working on:

-AID orphans outreach in Anhui
-Corporate Social Responsibility project (which reminded me about my upcoming internship with Baldwin Brothers Inc.)
-Summer intensive program for Chinese administrators (for AIDS management)

She spent a lot of time in China in the 1980s... in Beijing and Heilongjian (near Qiqihaer). And presently, she makes trips to China every three months.

She knows so much about health in China... I really enjoyed talking with her.

Inverse Power of Praise

by Po Bronson
NY Times

What do we make of a boy like Thomas?

Thomas (his middle name) is a fifth-grader at the highly competitive P.S. 334, the Anderson School on West 84th. Slim as they get, Thomas recently had his long sandy-blond hair cut short to look like the new James Bond (he took a photo of Daniel Craig to the barber). Unlike Bond, he prefers a uniform of cargo pants and a T-shirt emblazoned with a photo of one of his heroes: Frank Zappa. Thomas hangs out with five friends from the Anderson School. They are “the smart kids.” Thomas’s one of them, and he likes belonging.

Since Thomas could walk, he has heard constantly that he’s smart. Not just from his parents but from any adult who has come in contact with this precocious child. When he applied to Anderson for kindergarten, his intelligence was statistically confirmed. The school is reserved for the top one percent of all applicants, and an IQ test is required. Thomas didn’t just score in the top one percent. He scored in the top one percent of the top one percent.

But as Thomas has progressed through school, this self-awareness that he’s smart hasn’t always translated into fearless confidence when attacking his schoolwork. In fact, Thomas’s father noticed just the opposite. “Thomas didn’t want to try things he wouldn’t be successful at,” his father says. “Some things came very quickly to him, but when they didn’t, he gave up almost immediately, concluding, ‘I’m not good at this.’ ” With no more than a glance, Thomas was dividing the world into two—things he was naturally good at and things he wasn’t.

For instance, in the early grades, Thomas wasn’t very good at spelling, so he simply demurred from spelling out loud. When Thomas took his first look at fractions, he balked. The biggest hurdle came in third grade. He was supposed to learn cursive penmanship, but he wouldn’t even try for weeks. By then, his teacher was demanding homework be completed in cursive. Rather than play catch-up on his penmanship, Thomas refused outright. Thomas’s father tried to reason with him. “Look, just because you’re smart doesn’t mean you don’t have to put out some effort.” (Eventually, he mastered cursive, but not without a lot of cajoling from his father.)

Why does this child, who is measurably at the very top of the charts, lack confidence about his ability to tackle routine school challenges?

Thomas is not alone. For a few decades, it’s been noted that a large percentage of all gifted students (those who score in the top 10 percent on aptitude tests) severely underestimate their own abilities. Those afflicted with this lack of perceived competence adopt lower standards for success and expect less of themselves. They underrate the importance of effort, and they overrate how much help they need from a parent.

When parents praise their children’s intelligence, they believe they are providing the solution to this problem. According to a survey conducted by Columbia University, 85 percent of American parents think it’s important to tell their kids that they’re smart. In and around the New York area, according to my own (admittedly nonscientific) poll, the number is more like 100 percent. Everyone does it, habitually. The constant praise is meant to be an angel on the shoulder, ensuring that children do not sell their talents short.

But a growing body of research—and a new study from the trenches of the New York public-school system—strongly suggests it might be the other way around. Giving kids the label of “smart” does not prevent them from underperforming. It might actually be causing it.

For the past ten years, psychologist Carol Dweck and her team at Columbia (she’s now at Stanford) studied the effect of praise on students in a dozen New York schools. Her seminal work—a series of experiments on 400 fifth-graders—paints the picture most clearly.

Dweck sent four female research assistants into New York fifth-grade classrooms. The researchers would take a single child out of the classroom for a nonverbal IQ test consisting of a series of puzzles—puzzles easy enough that all the children would do fairly well. Once the child finished the test, the researchers told each student his score, then gave him a single line of praise. Randomly divided into groups, some were praised for their intelligence. They were told, “You must be smart at this.” Other students were praised for their effort: “You must have worked really hard.”

Why just a single line of praise? “We wanted to see how sensitive children were,” Dweck explained. “We had a hunch that one line might be enough to see an effect.”

Then the students were given a choice of test for the second round. One choice was a test that would be more difficult than the first, but the researchers told the kids that they’d learn a lot from attempting the puzzles. The other choice, Dweck’s team explained, was an easy test, just like the first. Of those praised for their effort, 90 percent chose the harder set of puzzles. Of those praised for their intelligence, a majority chose the easy test. The “smart” kids took the cop-out.

Why did this happen? “When we praise children for their intelligence,” Dweck wrote in her study summary, “we tell them that this is the name of the game: Look smart, don’t risk making mistakes.” And that’s what the fifth-graders had done: They’d chosen to look smart and avoid the risk of being embarrassed.

In a subsequent round, none of the fifth-graders had a choice. The test was difficult, designed for kids two years ahead of their grade level. Predictably, everyone failed. But again, the two groups of children, divided at random at the study’s start, responded differently. Those praised for their effort on the first test assumed they simply hadn’t focused hard enough on this test. “They got very involved, willing to try every solution to the puzzles,” Dweck recalled. “Many of them remarked, unprovoked, ‘This is my favorite test.’ ” Not so for those praised for their smarts. They assumed their failure was evidence that they weren’t really smart at all. “Just watching them, you could see the strain. They were sweating and miserable.”

Having artificially induced a round of failure, Dweck’s researchers then gave all the fifth-graders a final round of tests that were engineered to be as easy as the first round. Those who had been praised for their effort significantly improved on their first score—by about 30 percent. Those who’d been told they were smart did worse than they had at the very beginning—by about 20 percent.

Dweck had suspected that praise could backfire, but even she was surprised by the magnitude of the effect. “Emphasizing effort gives a child a variable that they can control,” she explains. “They come to see themselves as in control of their success. Emphasizing natural intelligence takes it out of the child’s control, and it provides no good recipe for responding to a failure.”

In follow-up interviews, Dweck discovered that those who think that innate intelligence is the key to success begin to discount the importance of effort. I am smart, the kids’ reasoning goes; I don’t need to put out effort. Expending effort becomes stigmatized—it’s public proof that you can’t cut it on your natural gifts.

Repeating her experiments, Dweck found this effect of praise on performance held true for students of every socioeconomic class. It hit both boys and girls—the very brightest girls especially (they collapsed the most following failure). Even preschoolers weren’t immune to the inverse power of praise.

Jill Abraham is a mother of three in Scarsdale, and her view is typical of those in my straw poll. I told her about Dweck’s research on praise, and she flatly wasn’t interested in brief tests without long-term follow-up. Abraham is one of the 85 percent who think praising her children’s intelligence is important. Her kids are thriving, so she’s proved that praise works in the real world. “I don’t care what the experts say,” Jill says defiantly. “I’m living it.”

Even those who’ve accepted the new research on praise have trouble putting it into practice. Sue Needleman is both a mother of two and an elementary-school teacher with eleven years’ experience. Last year, she was a fourth-grade teacher at Ridge Ranch Elementary in Paramus, New Jersey. She has never heard of Carol Dweck, but the gist of Dweck’s research has trickled down to her school, and Needleman has learned to say, “I like how you keep trying.” She tries to keep her praise specific, rather than general, so that a child knows exactly what she did to earn the praise (and thus can get more). She will occasionally tell a child, “You’re good at math,” but she’ll never tell a child he’s bad at math.

But that’s at school, as a teacher. At home, old habits die hard. Her 8-year-old daughter and her 5-year-old son are indeed smart, and sometimes she hears herself saying, “You’re great. You did it. You’re smart.” When I press her on this, Needleman says that what comes out of academia often feels artificial. “When I read the mock dialogues, my first thought is, Oh, please. How corny.”

No such qualms exist for teachers at the Life Sciences Secondary School in East Harlem, because they’ve seen Dweck’s theories applied to their junior-high students. Last week, Dweck and her protégée, Lisa Blackwell, published a report in the academic journal Child Development about the effect of a semester-long intervention conducted to improve students’ math scores.

Life Sciences is a health-science magnet school with high aspirations but 700 students whose main attributes are being predominantly minority and low achieving. Blackwell split her kids into two groups for an eight-session workshop. The control group was taught study skills, and the others got study skills and a special module on how intelligence is not innate. These students took turns reading aloud an essay on how the brain grows new neurons when challenged. They saw slides of the brain and acted out skits. “Even as I was teaching these ideas,” Blackwell noted, “I would hear the students joking, calling one another ‘dummy’ or ‘stupid.’ ” After the module was concluded, Blackwell tracked her students’ grades to see if it had any effect.

It didn’t take long. The teachers—who hadn’t known which students had been assigned to which workshop—could pick out the students who had been taught that intelligence can be developed. They improved their study habits and grades. In a single semester, Blackwell reversed the students’ longtime trend of decreasing math grades.

The only difference between the control group and the test group were two lessons, a total of 50 minutes spent teaching not math but a single idea: that the brain is a muscle. Giving it a harder workout makes you smarter. That alone improved their math scores.

“These are very persuasive findings,” says Columbia’s Dr. Geraldine Downey, a specialist in children’s sensitivity to rejection. “They show how you can take a specific theory and develop a curriculum that works.” Downey’s comment is typical of what other scholars in the field are saying. Dr. Mahzarin Banaji, a Harvard social psychologist who is an expert in stereotyping, told me, “Carol Dweck is a flat-out genius. I hope the work is taken seriously. It scares people when they see these results.”

Since the 1969 publication of The Psychology of Self-Esteem, in which Nathaniel Branden opined that self-esteem was the single most important facet of a person, the belief that one must do whatever he can to achieve positive self-esteem has become a movement with broad societal effects. Anything potentially damaging to kids’ self-esteem was axed. Competitions were frowned upon. Soccer coaches stopped counting goals and handed out trophies to everyone. Teachers threw out their red pencils. Criticism was replaced with ubiquitous, even undeserved, praise.

Dweck and Blackwell’s work is part of a larger academic challenge to one of the self-esteem movement’s key tenets: that praise, self-esteem, and performance rise and fall together. From 1970 to 2000, there were over 15,000 scholarly articles written on self-esteem and its relationship to everything—from sex to career advancement. But results were often contradictory or inconclusive. So in 2003 the Association for Psychological Science asked Dr. Roy Baumeister, then a leading proponent of self-esteem, to review this literature. His team concluded that self-esteem was polluted with flawed science. Only 200 of those 15,000 studies met their rigorous standards.

After reviewing those 200 studies, Baumeister concluded that having high self-esteem didn’t improve grades or career achievement. It didn’t even reduce alcohol usage. And it especially did not lower violence of any sort. (Highly aggressive, violent people happen to think very highly of themselves, debunking the theory that people are aggressive to make up for low self-esteem.) At the time, Baumeister was quoted as saying that his findings were “the biggest disappointment of my career.”

Now he’s on Dweck’s side of the argument, and his work is going in a similar direction: He will soon publish an article showing that for college students on the verge of failing in class, esteem-building praise causes their grades to sink further. Baumeister has come to believe the continued appeal of self-esteem is largely tied to parents’ pride in their children’s achievements: It’s so strong that “when they praise their kids, it’s not that far from praising themselves.”

By and large, the literature on praise shows that it can be effective—a positive, motivating force. In one study, University of Notre Dame researchers tested praise’s efficacy on a losing college hockey team. The experiment worked: The team got into the playoffs. But all praise is not equal—and, as Dweck demonstrated, the effects of praise can vary significantly depending on the praise given. To be effective, researchers have found, praise needs to be specific. (The hockey players were specifically complimented on the number of times they checked an opponent.)

Sincerity of praise is also crucial. Just as we can sniff out the true meaning of a backhanded compliment or a disingenuous apology, children, too, scrutinize praise for hidden agendas. Only young children—under the age of 7—take praise at face value: Older children are just as suspicious of it as adults.

Psychologist Wulf-Uwe Meyer, a pioneer in the field, conducted a series of studies where children watched other students receive praise. According to Meyer’s findings, by the age of 12, children believe that earning praise from a teacher is not a sign you did well—it’s actually a sign you lack ability and the teacher thinks you need extra encouragement. And teens, Meyer found, discounted praise to such an extent that they believed it’s a teacher’s criticism—not praise at all—that really conveys a positive belief in a student’s aptitude.

In the opinion of cognitive scientist Daniel T. Willingham, a teacher who praises a child may be unwittingly sending the message that the student reached the limit of his innate ability, while a teacher who criticizes a pupil conveys the message that he can improve his performance even further.

New York University professor of psychiatry Judith Brook explains that the issue for parents is one of credibility. “Praise is important, but not vacuous praise,” she says. “It has to be based on a real thing—some skill or talent they have.” Once children hear praise they interpret as meritless, they discount not just the insincere praise, but sincere praise as well.

Scholars from Reed College and Stanford reviewed over 150 praise studies. Their meta-analysis determined that praised students become risk-averse and lack perceived autonomy. The scholars found consistent correlations between a liberal use of praise and students’ “shorter task persistence, more eye-checking with the teacher, and inflected speech such that answers have the intonation of questions.”

Dweck’s research on overpraised kids strongly suggests that image maintenance becomes their primary concern—they are more competitive and more interested in tearing others down. A raft of very alarming studies illustrate this.

In one, students are given two puzzle tests. Between the first and the second, they are offered a choice between learning a new puzzle strategy for the second test or finding out how they did compared with other students on the first test: They have only enough time to do one or the other. Students praised for intelligence choose to find out their class rank, rather than use the time to prepare.

In another, students get a do-it-yourself report card and are told these forms will be mailed to students at another school—they’ll never meet these students and don’t know their names. Of the kids praised for their intelligence, 40 percent lie, inflating their scores. Of the kids praised for effort, few lie.

When students transition into junior high, some who’d done well in elementary school inevitably struggle in the larger and more demanding environment. Those who equated their earlier success with their innate ability surmise they’ve been dumb all along. Their grades never recover because the likely key to their recovery—increasing effort—they view as just further proof of their failure. In interviews many confess they would “seriously consider cheating.”

Students turn to cheating because they haven’t developed a strategy for handling failure. The problem is compounded when a parent ignores a child’s failures and insists he’ll do better next time. Michigan scholar Jennifer Crocker studies this exact scenario and explains that the child may come to believe failure is something so terrible, the family can’t acknowledge its existence. A child deprived of the opportunity to discuss mistakes can’t learn from them.

My son, Luke, is in kindergarten. He seems supersensitive to the potential judgment of his peers. Luke justifies it by saying, “I’m shy,” but he’s not really shy. He has no fear of strange cities or talking to strangers, and at his school, he has sung in front of large audiences. Rather, I’d say he’s proud and self-conscious. His school has simple uniforms (navy T-shirt, navy pants), and he loves that his choice of clothes can’t be ridiculed, “because then they’d be teasing themselves too.”

After reading Carol Dweck’s research, I began to alter how I praised him, but not completely. I suppose my hesitation was that the mind-set Dweck wants students to have—a firm belief that the way to bounce back from failure is to work harder—sounds awfully clichéd: Try, try again.

But it turns out that the ability to repeatedly respond to failure by exerting more effort—instead of simply giving up—is a trait well studied in psychology. People with this trait, persistence, rebound well and can sustain their motivation through long periods of delayed gratification. Delving into this research, I learned that persistence turns out to be more than a conscious act of will; it’s also an unconscious response, governed by a circuit in the brain. Dr. Robert Cloninger at Washington University in St. Louis located the circuit in a part of the brain called the orbital and medial prefrontal cortex. It monitors the reward center of the brain, and like a switch, it intervenes when there’s a lack of immediate reward. When it switches on, it’s telling the rest of the brain, “Don’t stop trying. There’s dopa [the brain’s chemical reward for success] on the horizon.” While putting people through MRI scans, Cloninger could see this switch lighting up regularly in some. In others, barely at all.

What makes some people wired to have an active circuit?

Cloninger has trained rats and mice in mazes to have persistence by carefully not rewarding them when they get to the finish. “The key is intermittent reinforcement,” says Cloninger. The brain has to learn that frustrating spells can be worked through. “A person who grows up getting too frequent rewards will not have persistence, because they’ll quit when the rewards disappear.”

That sold me. I’d thought “praise junkie” was just an expression—but suddenly, it seemed as if I could be setting up my son’s brain for an actual chemical need for constant reward.

What would it mean, to give up praising our children so often? Well, if I am one example, there are stages of withdrawal, each of them subtle. In the first stage, I fell off the wagon around other parents when they were busy praising their kids. I didn’t want Luke to feel left out. I felt like a former alcoholic who continues to drink socially. I became a Social Praiser.

Then I tried to use the specific-type praise that Dweck recommends. I praised Luke, but I attempted to praise his “process.” This was easier said than done. What are the processes that go on in a 5-year-old’s mind? In my impression, 80 percent of his brain processes lengthy scenarios for his action figures.

But every night he has math homework and is supposed to read a phonics book aloud. Each takes about five minutes if he concentrates, but he’s easily distracted. So I praised him for concentrating without asking to take a break. If he listened to instructions carefully, I praised him for that. After soccer games, I praised him for looking to pass, rather than just saying, “You played great.” And if he worked hard to get to the ball, I praised the effort he applied.

Just as the research promised, this focused praise helped him see strategies he could apply the next day. It was remarkable how noticeably effective this new form of praise was.

Truth be told, while my son was getting along fine under the new praise regime, it was I who was suffering. It turns out that I was the real praise junkie in the family. Praising him for just a particular skill or task felt like I left other parts of him ignored and unappreciated. I recognized that praising him with the universal “You’re great—I’m proud of you” was a way I expressed unconditional love.

Offering praise has become a sort of panacea for the anxieties of modern parenting. Out of our children’s lives from breakfast to dinner, we turn it up a notch when we get home. In those few hours together, we want them to hear the things we can’t say during the day—We are in your corner, we are here for you, we believe in you.

In a similar way, we put our children in high-pressure environments, seeking out the best schools we can find, then we use the constant praise to soften the intensity of those environments. We expect so much of them, but we hide our expectations behind constant glowing praise. The duplicity became glaring to me.

Eventually, in my final stage of praise withdrawal, I realized that not telling my son he was smart meant I was leaving it up to him to make his own conclusion about his intelligence. Jumping in with praise is like jumping in too soon with the answer to a homework problem—it robs him of the chance to make the deduction himself.

But what if he makes the wrong conclusion?

Can I really leave this up to him, at his age?

I’m still an anxious parent. This morning, I tested him on the way to school: “What happens to your brain, again, when it gets to think about something hard?”

“It gets bigger, like a muscle,” he responded, having aced this one before.
