Education expert, author, and New York University professor Diane Ravitch believes that students are more than just their test scores. Her bestselling book, The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education, positions Ravitch as one of the most outspoken critics of the recent wave of education reformers. Her current viewpoints are a sharp departure from the beliefs she held in the 1990s when she served as Assistant Secretary of Education under both President George H. W. Bush and President Bill Clinton. Ravitch shared with us her recipe for improving academic achievement in our nation’s schools.

Please note: This is part two in a two-part series. Read the first installment here.

GOOD: What do you say to reformers who say that poverty doesn’t matter and teachers should be able to get the same results regardless of a child’s income?


DIANE RAVITCH: People who say that poverty doesn’t matter are just blowing smoke. When you look at the Harlem Children’s Zone, it is a model that takes care of medical issues and social problems and family problems. Whether it has effects on test scores or not, that’s great because human needs should be addressed. HCZ gets good results but not amazing results. On the last state tests, only 40 percent of the kids were proficient. In Geoffrey Canada’s seventh grade where the kids had been there for three years, only 15 percent of them met the state standards.

By the way, HCZ proves that resources do matter because his organization has over $200 million in assets. I suspect that if any neighborhood public school in Harlem had the resources of Geoffrey Canada—if they too could have a classroom with 15 children with two teachers, they could get the same results, or even better.

GOOD: Why then the reluctance to talk about poverty’s connection to educational achievement?

DR: ?It’s a lot easier to talk about firing teachers than doing something about poverty. At least 20 percent of our kids live in poverty—which puts us up there with third world countries like Mexico and Turkey. Davis Guggenheim compares us to Finland. Finland has fewer than four percent of children in poverty.

To say that the schools are responsible for poverty—no, it’s the economy, it’s industrialization, it’s the shipping of jobs overseas. We have some serious economic problems and somehow the entire onus is on teachers. For the past several months I’ve been on the road talking to teachers and they are deeply demoralized. We can’t improve our schools by beating up on teachers.

GOOD: Are there adjustments needed in the way unions roll out tenure or react to teacher evaluations?

DR: Unions don’t write the rules. Wherever you have a contract, it’s signed by both parties. Management and unions sit together and negotiate the contract. If management doesn’t like the contract, it should insist on changing the rules. Tenure doesn’t mean you have lifetime employment. Tenure means after you’ve taught for a certain number of years—in most places it’s three years and in some it’s four—someone in management decides that you’re good enough that you get due process rights.

Teachers don’t give themselves tenure. Management gives them tenure. Management has three to four years to say, you’re not a good teacher; you’re fired. That’s not what they do in other countries. What they do in other countries is they get teachers help—they get support, they get mentored.

We have a problem in this country. We have 3.5 million teachers and about 300,000 leave the teaching profession every year. Some of them retire, some of them are fired, some of them leave voluntarily because they think it’s not for them. They don’t feel successful. The working conditions are miserable and they haven’t had any support.

One of the academic experts in Waiting for “Superman” says we should be firing six to ten percent more teachers every year. That would mean we’d have to find 500,000 new teachers every year. That’s really hard because there are only 1.5 million college graduates every year. We’re doing very little to create a strong and resilient teaching profession.

Instead we’re creating a revolving door where we say if you’re no good, you’re out and let’s bring in Teach For America. They’ll send in 8,000 kids to stay for two years and then they’re gone. This is no way to build a profession. What we’d do if we’re serious about education—which I think we’re not—would be to develop a strong teaching profession. That’s what they’ve done in other countries that we look at enviously, like Finland and Korea and Japan.

GOOD: What should the average citizen be doing to advocate for public education?

DR: I was in San Diego last week and I’m very impressed with what’s happening there. There’s a partnership between the school board, the district leadership, and the teachers union. They’re trying to develop what they call “community based school reform.” In every school there’ll be this same partnership between the principal, the teachers, the parents, the kids—and people will work in a collaborative atmosphere, not a confrontational one.

It sounds great, but the California legislature has proposed another $140 million in budget cuts and there’ll probably be another 1,000 teachers losing their jobs and class sizes going up. Because of the atmosphere in the country, what we’re hearing from Washington and from Davis Guggenheim and Waiting for “Superman,” people are saying, well, we’re spending enough on education, why should we tax ourselves for our schools? So instead of improving schools we’re going to see budget cutting and a loss of experienced teachers all across the country.

GOOD: There’s no silver bullet that can improve public education, but given everything you know, if you could change one thing, what would it be?

DR: I have asked in Washington and been rejected, why not require every school that receives federal funding have a full program of the arts and music and visual arts and performance arts. They said they can’t do that. But those are things that bring kids together. Those are things that motivate kids to come to school—especially in the inner city. No Child Left Behind has so dumbed things down that large numbers of kids just spend their days preparing to take the next test.

  • Foreign aid’s hidden benefit: Recipients are more likely to pay the generosity forward

    Foreign aid may not improve how recipients view donor countries – but it can set off a chain of goodwill that spreads far beyond the original act of giving.

    That is what a colleague and I found when we studied how South Koreans responded to COVID-19 vaccines donated by the United States.

    The South Korean government reserved donated Johnson & Johnson vaccines for military reservists and, for medical reasons, excluded anyone under 30. As a result, we could compare the views of South Koreans just above and below that threshold.

    We found that the donated vaccines did not improve people’s views of the United States. South Koreans who received American vaccines reported similar views of the U.S. as those who had not been vaccinated.

    Yet the results were striking in another way. Those who received donated American vaccines became more supportive of their own government sending aid abroad. Recipients shifted from neutrality on the matter to expressing moderate support for foreign aid, scoring about one point higher on a seven-point scale than those who didn’t make the eligibility cutoff.

    There is also evidence that these effects extend beyond direct recipients. South Koreans who were simply told that the U.S. was providing vaccine aid to developing countries also became more supportive of their own government doing the same – though this effect was concentrated among political moderates.

    Together, these patterns point to what social scientists call “generalized reciprocity” – the impulse not to repay kindness directly but to pass it on. In this way, one act of aid can prompt another, and spread across borders.

    Why it matters

    From Washington and London to Berlin and Tokyo, foreign aid budgets have been cut. In November 2020, former U.S. Agency for International Development Administrator Samantha Power invoked a common assumption when she argued that providing vaccines abroad would restore American leadership – that the value of aid lies in the goodwill it generates toward the donor.

    Our findings suggest this is one way aid can matter, but not necessarily the most important.

    Instead, aid may foster a form of international cooperation that does not depend on treaties or direct reciprocity between nations but emerges from ordinary people’s willingness to pass on goodwill.

    If aid can trigger chains of giving across borders, then how we assess its value may need to change. Current frameworks tend to emphasize donor nations’ direct returns or strategic benefits, but the cooperative effects we identify are largely invisible to those metrics.

    This suggests that current cuts may be shutting down effects that policymakers have not yet learned to measure – a form of international cooperation that, once set in motion, can generate cascading effects well beyond what any single donor nation could achieve alone.

    What we don’t know

    Important questions remain: Do similar patterns emerge with other forms of aid – such as disaster relief, food assistance or long-term development programs? And how long do these effects last?

    There are also hints that the threshold for triggering this response may be lower than previously thought. The effect persisted even when using eligibility for donated vaccines, rather than actual receipt, as the measure – suggesting proximity to aid, not just receipt, may be enough to activate the impulse to give.

    If evidence that past recipients of aid have themselves become donors strengthens public support for giving in donor countries, then aid may be more self-sustaining than critics assume – reinforced not just by its immediate effects, but by the example it sets.

  • Photographic memory is a myth – here’s what research really says about remembering
    Photo credit: F.J. Jimenez/Moment via Getty ImagesYour memory is not a camera.

    Hollywood loves a superpower. Not all involve capes or cosmic rays. Some are cognitive: characters who can remember everything. In movies and on TV, viewers repeatedly encounter those with extraordinary minds who glance once at a page, a room or a face – and later recreate every detail with surgical precision.

    You see it everywhere: “Suits,” “Sherlock” and “The Girl with the Dragon Tattoo.” Even in children’s literature there’s fifth grader Cam Jansen, who activates her photolike memory by saying “Click!”

    Most recently, it appeared in the television series “The Pitt,” set in a hospital emergency department. When the digital patient board suddenly went offline, medical student Joy Kwon saved the day by effortlessly reciting from memory every lost detail – names, rooms, doctors, conditions, vitals. It’s a gripping moment. The stakes are high, recall is perfect, and the implication is clear: Some people have minds that function like high-resolution cameras.

    The idea of photographic memory is simple and powerful: Experience is captured objectively, stored completely and retrieved perfectly. See it once, keep it forever.

    There’s just one problem. There’s no scientific evidence it exists.

    Your memory doesn’t record, it reconstructs

    As a memory researcher, I understand that belief in photographic memory is common and the idea is compelling. But it is simply wrong.

    Human memory does not work like a recording device. It’s a reconstructive process even among those with the most extraordinary skills. When you recall an event, memory doesn’t just hand you your experiences the same way every time. It’s never a matter of simply accessing, retrieving and playing back a static record of a stored slice of the past.

    Rather, you reconstruct the past by piecing together the remnants of experience available to you in the moment of recollection. It’s a process shaped by a range of factors, including the search cues you use; your present knowledge, attitudes and goals; and your current state of mind or mood.

    Because each of these factors is dynamic and changing, you’ll remember the past differently today – if ever so slightly – from how you remembered it yesterday, and differently from how you’ll remember it tomorrow. What you remember is not only incomplete but also inexact.

    A closer look at extraordinary memory

    Some people, such as memory competition champions, do have extraordinary memories. They can memorize thousands of digits or entire decks of cards in minutes. Their feats are real, but they don’t come from a memory that takes mental snapshots.

    Instead, these people rely on strategies – mental frameworks built through thousands of hours of deliberate practice to scaffold their memory in specific domains. Without these strategies and in other aspects of life, their recall looks pretty much like everyone else’s. Experts’ performance reflects better methods, not different machinery.

    In the scientific literature, the ability that comes closest to photographic memory is eidetic imagery: a form of visual mental imagery in which people claim they can briefly continue to “see” pictures they carefully studied and that are then removed from view.

    This ability is rare, is seen mostly in children, and usually disappears by adolescence. Even at its peak, however, it falls short of the Hollywood ideal. Eidetic images fade quickly and are not perfectly accurate. They can include distortions and even details that were not seen.

    It’s exactly what you’d expect from a reconstructive memory system – and exactly what you would not expect from a literal recording.

    Forgetting is a feature and not a flaw

    The myth about photographic memories feeds into the idea that your memory has failed if you can’t remember – that if your memory worked right, it would operate like a camera. When you can’t retrieve information or you lose it entirely, it can feel like something has gone wrong.

    In reality, forgetting is functional. Without it, we’d never get by.

    For instance, people use their memories of the past to forecast the future. Perfect memory would be a liability. Forgetting washes out the details of specific episodes and retains the gist so you can apply past experiences to novel situations, not just those that exactly match what happened before.

    Forgetting also guards your emotional health. The dulling of memories for negative events, like say an embarrassing episode, makes it easier for you to move on than if you reexperienced all the details in full force every time the event came to mind.

    Forgetting protects your sense of self as well. Memories of your past form the foundation of your identity. To help maintain a stable self-concept, people selectively modify or even forget those memories that challenge their views of themselves.

    The rare individuals who come closest to having near-perfect memory often reveal the downsides. People with highly superior autobiographical memory can remember nearly every day of their lives in vivid detail. If you ask one of these people to recall what they did on Nov. 24, 1999, they likely can tell you.

    Their extraordinary ability seems to come from a habitual, even compulsive, reflection on their past and a focus on anchoring memories to dates. However, this skill is limited to autobiographical events, and they are prone to various kinds of memory distortions and errors just like everyone else.

    While this ability might sound like an advantage, many people with highly superior autobiographical memory describe it as exhausting. They struggle to move past negative experiences because their memories make them seem as sharp as ever.

    Accurate – and empowering – view of memory

    Beliefs about “perfect memory” shape how people judge studentseyewitnessespatients and even themselves. They influence legal decisions, educational practices and unrealistic expectations about what human minds can – and should – do.

    Letting go of the camera metaphor could be a step toward better understanding how memory works. The brain is not a roll of film, it’s a storyteller – one that edits, interprets and reshapes the past in light of the present.

    And that’s not a limitation. It’s a superpower.

  • How workplace stress hijacks the nervous system to cause headaches − and a neurologist’s guide to managing them
    Photo credit: Sean Gladwell/Moment via Getty ImagesOngoing stress can send the nervous system into a state of heightened sensitivity.

    Many people finish the workday not just tired but wired. Their mind keeps racing, their body feels tense, and even in moments that should be restful they feel a lingering sense of urgency. Conversations replay in their mind, unfinished tasks resurface, and their nervous system seems unwilling to power down.

    You may recognize this experience. It has become so common that it is often accepted as the norm in modern professional life. Yet this persistent state of activation carries consequences for physical health, especially for people prone to headaches.

    As a board-certified neurologist who specializes in headache medicine, I see a lot of patients whose pain increases from the high-pressure work culture prevalent today. While it might seem beyond your control, there are some steps you can take.

    Stress and the nervous system

    Stress is not inherently harmful. In fact, when experienced in short bursts, stress can be beneficial by increasing focus, improving performance and preparing the body to handle challenges. However, problems arise when stress becomes chronic and relentless.

    The nervous system perceives and processes both stress and pain. Built to be highly adaptable, it continually responds to internal signals and external factors, constantly recalibrating to maintain balance. When the brain continuously perceives ongoing demands without adequate recovery, it keeps the body in a prolonged state of alertness.

    During these periods of ongoing stress, hormones such as cortisol and adrenaline remain persistently elevated. In this sensitized state, signals that would typically be ignored or interpreted as minor can start to feel much more intense.

    This state leads to an increase in heart rate and sustained muscle tension, with the nervous system transitioning into continuous fight or flight mode. In the context of headaches, this sensitization can lower the threshold for pain, making it easier for a headache to start and harder for it to stop.

    Over time, this constant activation can disrupt the body’s natural balance and create an environment for headache disorders to develop or worsen.

    Chronic stress acts as both a trigger and an exacerbating factor for migraines. The neurological system of people who experience migraines is comparatively more responsive to environmental changes, including variations in sleep patterns, the environment, hormonal fluctuations and stress intensity.

    This means that persistent exposure to stress may drive up frequency and severity of migraine episodes. In addition, muscle tension in the neck, shoulders and scalp – a frequent effect of stress – can cause tension headaches, too.

    Extended periods of sitting, sustained concentration and physical tension during the workday can contribute to the development of tension headaches in the later hours of the day.

    The role of sleep

    Chronic stress can also have a profound impact on sleep quality. Many people who feel persistently wired at the end of the workday struggle to fall asleep or stay asleep. That fitful sleep may lack the restorative qualities necessary for recovery.

    Poor sleep can, in turn, perpetuate the stress cycle, leaving the brain further sensitized and increasing the likelihood of headaches the following day. This loop can be difficult to break, as fatigue reduces resilience and amplifies the sense of being overwhelmed that comes with stress.

    In addition to affecting sleep, chronic stress impairs concentration and cognitive function. When the brain remains in a state of constant vigilance, scanning for demands and threats, it becomes harder to focus, be creative and solve problems. As a result, productivity declines, errors become more frequent and frustration mounts, adding to the overall stress burden.

    Headaches that occur alongside these cognitive challenges can further disrupt daily life, making even routine tasks feel difficult.

    Managing work stress

    Understanding the connection between stress and the nervous system points to some steps you can take to shift the nervous system out of its constantly activated state. You’ll never eliminate stress entirely – that’s neither realistic nor necessary. But it is possible to create intentional space for the body to reset:

    Small, consistent strategies that address both biological and lifestyle causes of headaches can minimize the effects of chronic stress and encourage nervous system regulation. Over time, these strategies can gradually reduce headache frequency and severity, improving overall quality of life.
