I’ve Just Met a Face

January 3, 2019

Each month, the Harvard Business Review has a feature called “Defend Your Research.” I confess, I am not a regular HBR reader, but as I was searching for something else, a serendipitous click whisked me to an episode of “Defend Your Research” that was about names, something I am interested in. The researcher, Anne-Laurier Sellier, had found that people look like their names. More specifically, people shown a photo of a stranger can make a better-than-chance guess as to what that person’s name is.(The HBR article is here.)

I was a tad skeptical. Hadn’t we been through something like this before with men named Dennis choosing to become dentists and women named Florence living in Florida? At least that research had a theory to explain the supposed connection — “implicit egotism” — even if the data turned out to be less than what met the researchers’ eye.* And now we have people named Charlotte choosing to look like a Charlotte?

Plausible or not, the empirical findings about faces and names were interesting, and I was curious to try my luck. Conveniently, Sellier had provided HBR two examples.

George, Scott, Adam, Bruce. Which could it be? “What if it's just that the other names on the list were rarer and less likely?” asks Scott Berinato, the HBR interviewer.

We controlled for that by offering only choices that were as popular as the actual name, based on the frequency of use. We controlled for most things we could think of, including ethnicity, name length, and the socioeconomic background of the subjects and of the people in the photos.

Any good researcher would control for these things. Everyone knows that. But “Bruce?” My spider sense suggested that the names Bruce and Scott are not really equivalent in popularity. To check, I went to the Social Security database on names.

The guy on the left looks like he’s about 40, the one on the right, early 30s. The HBR article came out in 2017. I guessed that the research was done a couple of years earlier. So I looked up the numbers for boy baby-names in 1975 for the older guy, 1983 for the younger. Here are the results.

And what are the answers to the name-that-face quiz? The man on the left is Scott. The man on the right is James. The correct name is two to three times more frequent than the second-most popular name on the list. It’s possible that Sellier’s subjects were putting together their estimate of the man’s age and their intuitive knowledge of name popularity. A better design might have been to show people four pictures of men roughly the same age and ask, “Which one is Scott?”

Maybe Sellier just picked the wrong examples to illustrate her point. After all, she says that she and her fellow researchers did this study in the US, France, and Israel and got positive results in all three countries. And they do have a theory — that people change their appearance so as to conform with the cultural stereotype of their name. “In America people presumably share a stereotype of what a Scott looks like. . . and Scotts want to fit that stereotype.”

I haven’t looked at Sellier’s publications. All I know is what I see in the HBR. Maybe, knowing that the HBR interviewer was named Scott, she picked a couple of photos — one Scott, one not-Scott — just for this occasion and selected Bruce and the other names on the spur of the moment. Still, I assume that a researcher being interviewed for a feature called “Defend Your Research” would bring examples that best illustrate her ideas. If this is the best she’s got, I’m afraid I remain unconvinced

The Charter School Advantage

December 31, 2018
Posted by Jay Livingston

In his Wall Street Journal op-ed that I criticized last week (here), Jason Riley begins with the story of a father who was desperate to get his kid into a charter school.

I thought he was going to tell me that the charter school had smaller classes or better graduation rates. Instead, he wanted to talk about something most parents take for granted when they send Johnny and Susie off to school each morning: physical safety. He didn’t take it for granted. He told me the atmosphere at the old school had been chaotic, that bullying was rampant, and that his son, a sixth-grader at the time, had become terrified of the place. One day the boy was attacked by other students in the school lavatory, and the father got a call to pick him up from the hospital. It was the final straw. “I didn’t know anything about charters,” said the father. “I was just looking for an escape.” After the new school assured him his child would not have to worry each day about being assaulted by his classmates, he was sold.

Riley uses this anecdotal evidence to support the decision by Trump’s Secretary of Education Betsy de Vos to rescind Obama administration efforts to reduce the disparity between discipline imposed on Black schoolkids and White schoolkids.

But this anecdote also speaks to another controversial issue in education — whether charter schools, compared with traditional public schools, do a better job of educating kids.  On that question, the scorecard is mixed. In most studies that compare charters with similarly situated publics, there’s little difference in students’ test scores. For the rest, in some places, the publics come out better. And in some cities — New York, for example —  some charters consistently outperform public schools.

Charter school boosters claim that charter students do better because their schools are unencumbered by the teachers’ unions and educational bureaucracies that hobble public schools. But critics point out that charter schools have one way of improving their test averages that is not available to the public schools, and it has nothing to do with unions or regulations: charter schools can get rid of bad students. If you can force out the low scorers, the school average will be higher not because the school does a better job of teaching but just because of the way an average is calculated.

That’s true. But the expulsion option has an impact far beyond the math. Difficult and disruptive kids don’t just bring down the class average because of their individual low scores. They affect the general atmosphere of the class and the school. As Riley’s anecdote illustrates, troublemakers make it harder for other kids to learn and harder for teachers to teach.

I wrote about this back in 2012 (here), but I was reminded of it a few weeks ago in a conversation with an expert on educational testing and measurement who also had once taught in a middle school. We were talking about rating teachers on the basis of student test scores. Disruptive kids in the classroom, he said, can undermine the efforts of a teacher. Even the good teacher who gets one kid like that is not going to score well on these measures. With more than one, the problem grows almost exponentially.

That atmosphere in the public school in Riley’s WSJ op-ed was chaotic not because of the UFT and not because of the Board of Ed. The “bureaucratic” regulation responsible for it was the law that requires public schools to find a place for all kids, even the very difficult ones.

“Other Than That, Merry Christmas”

December 28, 2018

Some countries have a ceremonial head of state — a person who stands above or at least apart form partisan politics and who therefore can more easily be seen as representative of the whole country. The UK has the Queen. It is the Queen, not the prime minister, who delivers the Christmas message.

When surveys ask Brits for the person they most admire, the Queen always wins. This year, Theresa May, the head of the government, didn’t even make the top five.

In the US, both roles — political/govermental leader and ceremonial head of state — fall to the president. The overlap can get tricky, but most US presidents, on ceremonial occasions, have tried to to avoid politics and to appeal to widely shared values and symbols. Their Christmas messages, for instance, project warmth and hope. Even if they mention problems (the suffering of those who are ill, poor, homeless, bereaved), they emphasize the American spirit that helps us overcome setbacks.

Donald Trump seems incapable of playing that role for more than a minute. The pre-recorded Christmas message from the Trumps (Donald and Melania) stayed true to the genre. But on Christmas day, Trump quickly returned to the spirit of Christmas Trump — belittling and combative. On Twitter, he wrote, “I hope everyone, even the Fake News Media, is having a great Christmas!” And speaking to reporters he concluded with, “It’s a disgrace what’s happening in this country. But, other than that I wish everybody a Merry Christmas.”*

Since 1946, the Gallup Poll has been asking Americans “What man that you have heard or read about, living today in any part of the world, do you admire most?” Nearly every year, the most admired man is the president or president-elect. In the graphic below, the names in red are most-admired men who were not.

When a president is not the most admired, it’s because of policy failures (Truman and Korea, LBJ and Vietnam plus domestic strife, Carter and stagflation) or personal failure (Nixon and Watergate). But with Trump, it’s something else. In most of the years in the chart, the president was not really doing anything unusually admirable. The admiration was directed to him not as a person or politician but as the symbol of the nation. For better or worse, he is our Queen. What has kept Trump from the top of the list for both years of his presidency is his unwillingness or inability to play that symbolic role.

(Earlier blogposts about our lack of a Queen are here and here )

---------------------
* I doubt that anyone was surprised that Trump lumped together this supposed national disgrace and the national holiday. After all, at his very first ceremonial occasion, the inauguration, he spoke of “this American carnage.” (In that speech, he assured us that the carnage would “stop right now.” That was two years ago. Apparently, the carnage has not been stopped but merely transformed into disgrace.)

The Ferguson Effect Goes to School

December 27, 2018
Posted by Jay Livingston

The “Ferguson Effect” has disappeared from the headlines. It doesn’t come up much in political discussions. But now, conservatives are pushing the same idea applied to schools.

In case you’ve forgotten, proponents of the Ferguson Effect sketch out this scenario:

• A White cop kills a Black person, usually an unarmed Black person.
• Black people protest.
• The government, dominated by liberals, pressures police to be less aggressive, especially towards African Americans. Sometimes cops who have killed Black people are prosecuted.
• Cops, to avoid being exposed to prosecution and accusations of racism, withdraw from proactive policing.
• Crime in Black neighborhoods increases.
• Conclusion: A policy intended to reduce racism winds up hurting Black people.

The fault, according to this model, is not in our cops but in our liberals.

For the schools version, just substitute teachers and administrators for police; substitue disruption/violence/bullying for crime. The villain remains the same — liberal government policies. The equivalent of consent decrees forced on police departments is an Obama-era policy that threatened schools with loss of funds for disproportionately punishing Black kids.

Betsy de Vos, Trump’s Secretary of Education, is rescinding that policy, and conservatives are cheering. Here is Jason S. Riley in the Wall Street Journal:

Racial parity in school discipline, regardless of who was being disruptive. . . is as silly as demanding racial parity in police arrests, regardless of who’s committing crimes.

If the Obama policy means that Black kids are less likely to be punished for an offense, then Black kids’ misbehavior that will increase. The losers will be the other kids in their schools. And since US schools are racially homogeneous, the anti-racism policy will wind up hurting Black people. According to Riley, this Ferguson Effect has already happened since the Obama policy went into effect in 2014.

The result is that more schools have been disciplining fewer students in order to achieve racial balance in suspension rates and stay out of trouble with the federal government. . .  In Oklahoma City, principals told teachers not to request a suspension “unless there was blood.”

The “blood” thing is a great quote, but if you are making generalizations about a nationwide policy, Oklahoma City is a very small n. Elsewhere in his article, Riley cites the report by the National Center for Education Statistics (here), a national survey, so that’s where I went for a broader view. The NCES asks teachers whether misbehavior is undermining their teaching.

(Click on a graph for a larger view.)

The graphs show no sharp changes after 2014. Misbehavior that interfered with teaching began to rise in 2007-2008 and continued to rise at about the same rate. Enforcement of school rules showed no change.

What were the effects of this supposed pullback in punishment? More bad stuff. Here’s Riley again.

After school districts in Los Angeles and Chicago softened their policies to curb suspensions, teachers reported more disorder, and students reported feeling less safe. Following a similar move in Philadelphia, truancy increased and academic achievement fell. Schools in Wisconsin that followed the guidance also saw subsequent reductions in math and reading proficiency.

Riley gives us three cities and one state, each with its own negative outcomes. It’s possible that these outcomes are related — more students feel unsafe so they stay away from school, and achievement falls. But Riley doesn’t tell us whether Los Angeles students, with their lower feelings of safety, also scored worse on tests of achievement. Or whether in Wisconsin, where achievement scores dropped, students also felt less safe. He mentions “disorder” but not actual crime or even bullying. Nor does he tell us the magnitude of these changes.

Were these cities and outcomes representative, or were they merely a few unusually juicy cherries that Riley picked? To get the more general picture, I went back to the NCES survey.  Had 2014 brought in a new era of  fear?

Fear decreased in the 1990s, and it leveled off in about 2010, and did not rise appreciably after that. There is no discernible effect of the 2014 policy. Bullying shows a roughly similar pattern.

In private schools, less affected by the Obama rules, bullying declined from 2013 to 2015. In public schools, it remained unchanged — hardly the effect Riley claims.

Finally, there is actual victimization. (The data is from the National Crime Victimization Survey.)

Victimization at school increased from 2010 to 2013. In 2014, the year when the new policy was introduced, victimization declined and has not risen since. So what can we say about the unintended consequences of the Obama policy? Where are those bad outcomes claimed by conservatives? On average nationwide, schools have not seen an increase in violence, crime, bullying, or fear.

This doesn’t mean that Riley is totally wrong. In some schools and some cities, decreased punishment of Black kids may have had the effects he claims. But it’s also possible that in some schools, the Obama policy had the good effects its proponents hoped for — Black schoolkids feeling less alienated, less resentful, and more positive towards school. At the very least, the policy did not lead to the nationwide crisis that conservatives would predict.

For the next two years (and perhaps more), thanks to DeVos-Trump, school staff will once again be free to punish who they wish, how they wish, without having to worry about charges of racism and without having to worry about federal pressure. If conservatives are right, bad things (bullying, crime) will decrease, and good things (attendance, learning) will increase, especially for Black kids.

Will that happen? No doubt, in 2020, our president will claim that because of this policy, schools are now beautiful, the best they have ever been in US history. The Wall Street Journal will publish cherry-picked success stories. The rest of us will have to wait for more systematic evidence.
