Parenting can feel harder when every decision arrives with a warning, a statistic or a “studies show” headline. In an April 1, 2026, Boston Globe interview, Brown University economist Emily Oster said the problem is not simply that parents have more information. It is that data often reaches them before they have chosen a question, and they must then sort strong evidence from weak claims while worrying that an ordinary moment could permanently damage a child.
Oster’s answer is neither “always follow the data” nor “ignore experts and trust your gut.” She recommends deciding whether a choice matters, identifying realistic options, examining the evidence for those options and then combining that evidence with the family’s preferences. The approach leaves room for instinct, but treats instinct as one part of a decision rather than a substitute for asking what is known.
The interview’s central distinction: evidence for a question versus data pushed into your feed
Oster made the distinction during a live recording of the Globe Opinion podcast Say More, held at the newspaper’s second annual Globe Working Mothers Summit on March 31, 2026. The published article is a lightly edited transcript of that conversation, not an independent review of every study mentioned. Its value is in showing how Oster thinks parents should reason when information is abundant and anxiety is high.
Useful evidence begins with a question a parent is actually trying to answer. For example: Should our family change a childcare arrangement? Is a particular diet workable for this child? How can we set a screen boundary that we can enforce? Those questions define the decision, the alternatives and the kind of evidence that could help.

The modern information stream often reverses that order. A parent opens a social-media app to relax and encounters an alarming claim about sleep, food, screens or development. The claim may be presented as settled science because it contains a chart, a citation or the phrase “studies show.” The parent is now doing two jobs at once: deciding whether the claim applies and assessing whether the underlying evidence is trustworthy. Oster described this environment bluntly: “A lot of that data is trash.”
Her point is not that all parenting data is useless. More data can improve an answer when investigators are studying a defined question and the findings are interpreted carefully. The difficulty is that a stream of disconnected claims can make every choice feel urgent, even when the decision has little lasting consequence or the evidence is too weak to support a confident rule.
Why information creates a feeling of permanent risk
Oster told the Globe that parents are often made to feel that each interaction is a possible turning point. “The current environment often makes us feel that every interaction with our child is an opportunity to ruin them forever,” she said. That framing converts routine care into a running audit: Was the snack optimal? Did the parent respond correctly to a tantrum? Did a missed activity erase an opportunity?
Such pressure is different from taking a serious decision seriously. It treats low-stakes moments as if they carry the same weight as health, safety or a major change in family circumstances. The result is not necessarily better decision-making. A parent who is flooded with warnings may spend attention on the most vivid claim rather than the most consequential choice.

Oster’s four-part decision process
Oster summarized her method in one sentence: “Good decision-making is about thinking, ‘What are my options?’ then trying to figure out what the evidence says about those options and combining that evidence with our preferences.” Applying that idea in practice involves four distinct moves.
- Ask whether the decision matters. Consider the possible consequences, how long they last and whether the choice is reversible. A minor clothing choice and a childcare change should not consume the same amount of research time or emotional energy.
- List the realistic options. Include the option of changing nothing. A comparison is useful only when it reflects what the family can actually do, not an idealized plan that depends on unlimited time, money or support.
- Examine the evidence for each option. Look for the question being studied, how outcomes were measured, whether the evidence applies to your circumstances and how much uncertainty remains. A headline alone cannot answer those questions.
- Add the family’s preferences. Work schedules, costs, culture, comfort with uncertainty, a child’s temperament and a parent’s own priorities all affect the decision. Preferences are not a failure to be objective; they are part of choosing among options.
This process allows “gut feeling” to have a legitimate place. A preference may be the reason one workable option fits a particular family better than another. But the parent first makes the options visible and checks what the available evidence can and cannot say.
Matching effort to the stakes
| Type of choice | Example raised in the interview | Reasonable level of analysis | What to keep in view |
|---|---|---|---|
| Low stakes or easily reversible | Whether a child wears mittens | A quick practical judgment | Comfort, weather and the child’s preference may be enough; an exhaustive evidence search is unlikely to improve the outcome. |
| Consequential and recurring | Childcare | Compare feasible arrangements and their trade-offs | Reliability, safety, cost, schedule, quality of care and what the family can sustain. |
| Health or nutrition decision | Diet | Clarify the goal, review applicable evidence and seek qualified advice when needed | Medical history, nutritional adequacy, feasibility and the difference between a general finding and individual care. |
| Family boundary requiring implementation | Screen use | Choose a workable policy and adjust it in practice | The household’s routines and enforcement matter as much as abstract information about effects. |
The table is an explanation of the framework, not a ranking of parenting choices or a claim that one policy is best. Stakes can differ between families, and a decision that is reversible for one household may be difficult for another.

Start with the question, not the headline
Rewrite a broad warning as a specific decision. “Are screens bad?” is too broad to guide a family. “What screen routine can we maintain on school nights, and what changes would tell us it is not working?” is a decision question. It makes room for the child’s age, the content, timing, family schedule and the outcome the parent cares about.
Separate evidence quality from confidence of presentation
A polished graphic, a large sample claim or a confident influencer does not establish that a finding is reliable or applicable. Parents can ask what was compared, what outcome was measured, how long the observation lasted and whether the result shows an association or a demonstrated cause. When those details are unavailable, the appropriate conclusion may be uncertainty rather than a new rule.

Check whether the finding fits the situation
Even a well-conducted study answers the question it examined, not every nearby question. A result involving a particular age group, setting or exposure may not transfer directly to a different child or household. Oster’s framework therefore treats applicability as part of evidence assessment, not an afterthought.
Include preferences without disguising them as facts
A parent may prefer a plan that is easier to maintain, costs less, preserves sleep or aligns with family values. Saying that openly is clearer than presenting the preference as if it were a scientific conclusion. The decision can be evidence-informed while still being personal.
Screens are the research area Oster says needs the most practical help
Oster said, “The place with the biggest gaps is screens.” In the interview, she was not claiming that one universal screen rule had been proven superior. She was describing a need for better evidence that helps families make boundaries work in ordinary life.
That distinction matters. Parents can find many statements about possible screen effects, but an abstract association does not automatically tell a household what to do at 7 p.m. on a difficult weekday. A useful answer would address implementation: how a boundary is explained, what happens when a child resists, how parents handle exceptions, and which outcomes signal that a routine should change. Oster identified this practical gap as a priority rather than supplying a settled prescription.
A family applying her method could define its goal first—protecting sleep, reducing conflict, preserving shared time or something else—then compare feasible routines and watch the outcomes that matter to that family. If a plan repeatedly fails, that is information about the plan’s fit, not proof that the parents have failed.

Medical and reproductive examples she discussed
Breast-milk storage: an anecdote, not a new guideline
Oster recounted that readers of her ParentData newsletter helped fund a breast-milk-storage study after a researcher contacted her. She said the resulting data suggested breast milk could be left out longer than previously thought. The Globe interview did not identify the researcher, study title, methods or numerical result.
That account should therefore be understood as Oster’s description of a project and its apparent finding, not as a verified change to medical guidance. Parents deciding how to store milk should consult current advice from an appropriate health authority or clinician for their circumstances. The interview supplies no basis for a new time limit.
Preventing fourth-degree vaginal tearing
Oster also said she wanted better evidence about preventing fourth-degree vaginal tearing. She presented this as a research priority. The interview does not establish which interventions work, how large the evidence gap is or what an individual patient should do.
Because this is a serious medical issue, a reader should not turn a stated research need into a treatment recommendation. Questions about risk, prevention and delivery planning belong with an obstetric clinician who can account for the patient’s history and current pregnancy.

The interview is not a standalone assessment of the balance of pandemic risks and harms, nor does it provide the underlying studies needed to resolve that historical debate. Reporting her position accurately means keeping it attributed to Oster rather than presenting it as an independently established conclusion. The episode illustrates the same broader problem she describes: consequential decisions require explicit options, evidence and values, while later certainty can hide how much uncertainty decision-makers faced at the time.
Why basic care matters more than perfect optimization
Against the pressure to optimize every exchange, Oster emphasized fundamentals. She objected to advice framed as a catalogue of parental losses and mistakes and pointed instead to enough food, a safe place and someone who loves the child. “The things that really matter in the data are a lot simpler than the idea that every single interaction is an opportunity to mess up,” she said.
This is not an argument that details never matter. Safety, health and reliable care deserve attention. It is an argument about proportion: a child’s basic conditions and durable relationships should not be obscured by an endless search for the perfect response to every small event.
A practical routine for parents facing a new claim
- Pause before adopting the claim. Notice whether it arrived unasked and whether it is provoking fear without identifying a decision.
- Name the decision. Write down what you may actually change and what outcome you want.
- Rate the stakes. If the choice is minor or reversible, a quick judgment may be sufficient. If it affects health, safety, care or a major routine, spend more time checking evidence.
- List feasible alternatives. Include your current arrangement and acknowledge constraints such as money, work and support.
- Inspect the source and uncertainty. Find out what was measured and whether the claim applies. If the original study or guidance is unavailable, lower your confidence.
- State your preferences. Explain which trade-offs your family accepts and why.
- Choose, observe and revisit. A decision can be updated when new information appears or the family’s circumstances change.
What this interview can—and cannot—answer
The conversation explains Oster’s philosophy of decision-making and her concerns about an information environment that amplifies fear. It does not provide a complete scientific review of screens, school reopening, breast-milk storage, diet, childcare or childbirth injuries. It contains no named study statistics that can be used as general parenting facts, and the milk-storage anecdote includes no published method or numerical result.

Oster’s larger message is a discipline of attention. Data is most useful when it answers a question a family has chosen, at a level of effort that matches the decision’s stakes. Preferences then help determine which workable option belongs in that family’s life. That approach does not remove uncertainty, but it can stop every passing claim from becoming a new emergency.
