Complex research papers and data flood academic journals daily, and science journalists play a pivotal role in disseminating that information to the public. This can be a daunting task, requiring a keen understanding of the subject matter and the ability to translate dense academic language into narratives that resonate with the general public.

Several resources and tip sheets, including the Know Your Research section here at The Journalist’s Resource, aim to help journalists hone their skills in reporting on academic research.

But what factors do science journalists look for to decide whether a social science research study is trustworthy and newsworthy? That’s the question researchers at the University of California, Davis, and the University of Melbourne in Australia examine in a recent study, “How Do Science Journalists Evaluate Psychology Research?” published in September in Advances in Methods and Practices in Psychological Science.

Their online survey of 181 mostly U.S.-based science journalists looked at how and whether they were influenced by four factors in fictitious research summaries: the sample size (number of participants in the study), sample representativeness (whether the participants in the study were from a convenience sample or a more representative sample), the statistical significance level of the result (just barely statistically significant or well below the significance threshold), and the prestige of a researcher’s university.

The researchers found that sample size was the only factor that had a robust influence on journalists’ ratings of how trustworthy and newsworthy a study finding was.

University prestige had no effect, while the effects of sample representativeness and statistical significance were inconclusive.

But there’s nuance to the findings, the authors note.

“I don’t want people to think that science journalists aren’t paying attention to other things, and are only paying attention to sample size,” says Julia Bottesini, an independent researcher, a recent Ph.D. graduate from the Psychology Department at UC Davis, and the first author of the study.

Overall, the results show that “these journalists are doing a very decent job” vetting research findings, Bottesini says.

Also, the findings from the study are not generalizable to all science journalists or other fields of research, the authors note.

“Instead, our conclusions should be circumscribed to U.S.-based science journalists who are at least somewhat familiar with the statistical and replication challenges facing science,” they write. (Over the past decade a series of projects have found that the results of many studies in psychology and other fields can’t be reproduced, leading to what has been called a ‘replication crisis.’)

“This [study] is just one tiny brick in the wall and I hope other people get excited about this topic and do more research on it,” Bottesini says.

More on the study’s findings

The study’s findings can be useful for researchers who want to better understand how science journalists read their research and what kind of intervention — such as teaching journalists about statistics — can help journalists better understand research papers.

“As an academic, I take away the idea that journalists are a great population to try to study because they’re doing something really important and it’s important to know more about what they’re doing,” says Ellen Peters, director of Center for Science Communication Research at the School of Journalism and Communication at the University of Oregon. Peters, who was not involved in the study, is also a psychologist who studies human judgment and decision-making.

Peters says the study was “overall terrific.” She adds that understanding how journalists do their work “is an incredibly important thing to do because journalists are who reach the majority of the U.S. with science news, so understanding how they’re reading some of our scientific studies and then choosing whether to write about them or not is important.”

The study, conducted between December 2020 and March 2021, is based on an online survey of journalists who said they at least sometimes covered science or other topics related to health, medicine, psychology, social sciences, or well-being. They were offered a $25 Amazon gift card as compensation.

Among the participants, 77% were women, 19% were men, 3% were nonbinary and 1% preferred not to say. About 62% said they had studied physical or natural sciences at the undergraduate level, and 24% at the graduate level. Also, 48% reported having a journalism degree. The study did not include the journalists’ news reporting experience level.

Participants were recruited through the professional network of Christie Aschwanden, an independent journalist and consultant on the study, which could be a source of bias, the authors note.

“Although the size of the sample we obtained (N = 181) suggests we were able to collect a range of perspectives, we suspect this sample is biased by an ‘Aschwanden effect’: that science journalists in the same professional network as C. Aschwanden will be more familiar with issues related to the replication crisis in psychology and subsequent methodological reform, a topic C. Aschwanden has covered extensively in her work,” they write.

Participants were randomly presented with eight of 22 one-paragraph fictitious social and personality psychology research summaries with fictitious authors. The summaries are posted on Open Science Framework, a free and open-source project management tool for researchers by the Center for Open Science, with a mission to increase openness, integrity and reproducibility of research.

For instance, one of the vignettes reads:

“Scientists at Harvard University announced today the results of a study exploring whether introspection can improve cooperation. 550 undergraduates at the university were randomly assigned to either do a breathing exercise or reflect on a series of questions designed to promote introspective thoughts for 5 minutes. Participants then engaged in a cooperative decision-making game, where cooperation resulted in better outcomes. People who spent time on introspection performed significantly better at these cooperative games (t (548) = 3.21, p = 0.001). ‘Introspection seems to promote better cooperation between people,’ says Dr. Quinn, the lead author on the paper.”

In addition to answering multiple-choice survey questions, participants were given the opportunity to answer open-ended questions, such as “What characteristics do you [typically] consider when evaluating the trustworthiness of a scientific finding?”

Bottesini says those responses illuminated how science journalists analyze a research study. Participants often mentioned the prestige of the journal in which it was published or whether the study had been peer-reviewed. Many also seemed to value experimental research designs over observational studies.

Considering statistical significance

When it came to considering p-values, “some answers suggested that journalists do take statistical significance into account, but only very few included explanations that suggested they made any distinction between higher or lower p values; instead, most mentions of p values suggest journalists focused on whether the key result was statistically significant,” the authors write.

Also, many participants mentioned that it was very important to talk to outside experts or researchers in the same field to get a better understanding of the finding and whether it could be trusted, the authors write.

“Journalists also expressed that it was important to understand who funded the study and whether the researchers or funders had any conflicts of interest,” they write.

Participants also “indicated that making claims that were calibrated to the evidence was also important and expressed misgivings about studies for which the conclusions do not follow from the evidence,” the authors write.

In response to the open-ended question, “What characteristics do you [typically] consider when evaluating the trustworthiness of a scientific finding?” some journalists wrote they checked whether the study was overstating conclusions or claims. Below are some of their written responses:

  • “Is the researcher adamant that this study of 40 college kids is representative? If so, that’s a red flag.”
  • “Whether authors make sweeping generalizations based on the study or take a more measured approach to sharing and promoting it.”
  • “Another major point for me is how ‘certain’ the scientists appear to be when commenting on their findings. If a researcher makes claims which I consider to be over-the-top about the validity or impact of their findings, I often won’t cover.”
  • “I also look at the difference between what an experiment actually shows versus the conclusion researchers draw from it — if there’s a big gap, that’s a huge red flag.”

Peters says the study’s findings show that “not only are journalists smart, but they have also gone out of their way to get educated about things that should matter.”

What other research shows about science journalists

A 2023 study, published in the International Journal of Communication, based on an online survey of 82 U.S. science journalists, aims to understand what they know and think about open-access research, including peer-reviewed journals and articles that don’t have a paywall, and preprints. Data was collected between October 2021 and February 2022. Preprints are scientific studies that have yet to be peer-reviewed and are shared on open repositories such as medRxiv and bioRxiv. The study finds that its respondents “are aware of OA and related issues and make conscious decisions around which OA scholarly articles they use as sources.”

A 2021 study, published in the Journal of Science Communication, looks at the impact of the COVID-19 pandemic on the work of science journalists. Based on an online survey of 633 science journalists from 77 countries, it finds that the pandemic somewhat brought scientists and science journalists closer together. “For most respondents, scientists were more available and more talkative,” the authors write. The pandemic has also provided an opportunity to explain the scientific process to the public, and remind them that “science is not a finished enterprise,” the authors write.

More than a decade ago, a 2008 study, published in PLOS Medicine, and based on an analysis of 500 health news stories, found that “journalists usually fail to discuss costs, the quality of the evidence, the existence of alternative options, and the absolute magnitude of potential benefits and harms,” when reporting on research studies. Giving time to journalists to research and understand the studies, giving them space for publication and broadcasting of the stories, and training them in understanding academic research are some of the solutions to fill the gaps, writes Gary Schwitzer, the study author.

Advice for journalists

We asked Bottesini, Peters, Aschwanden and Tamar Wilner, a postdoctoral fellow at the University of Texas, who was not involved in the study, to share advice for journalists who cover research studies. Wilner is conducting a study on how journalism research informs the practice of journalism. Here are their tips:

1. Examine the study before reporting it.

Does the study claim match the evidence? “One thing that makes me trust the paper more is if their interpretation of the findings is very calibrated to the kind of evidence that they have,” says Bottesini. In other words, if the study makes a claim in its results that’s far-fetched, the authors should present a lot of evidence to back that claim.

Not all surprising results are newsworthy. If you come across a surprising finding from a single study, Peters advises you to step back and remember Carl Sagan’s quote: “Extraordinary claims require extraordinary evidence.”

How transparent are the authors about their data? For instance, are the authors posting information such as their data and the computer codes they use to analyze the data on platforms such as Open Science Framework, AsPredicted, or The Dataverse Project? Some researchers ‘preregister’ their studies, which means they share how they’re planning to analyze the data before they see them. “Transparency doesn’t automatically mean that a study is trustworthy,” but it gives others the chance to double-check the findings, Bottesini says.

Look at the study design. Is it an experimental study or an observational study? Observational studies can show correlations but not causation.

“Observational studies can be very important for suggesting hypotheses and pointing us towards relationships and associations,” Aschwanden says.

Experimental studies can provide stronger evidence toward a cause, but journalists must still be cautious when reporting the results, she advises. “If we end up implying causality, then once it’s published and people see it, it can really take hold,” she says.

Know the difference between preprints and peer-reviewed, published studies. Peer-reviewed papers tend to be of higher quality than those that are not peer-reviewed. Read our tip sheet on the difference between preprints and journal articles.

Beware of predatory journals. Predatory journals are journals that “claim to be legitimate scholarly journals, but misrepresent their publishing practices,” according to a 2020 journal article, published in the journal Toxicologic Pathology,Predatory Journals: What They Are and How to Avoid Them.”

2. Zoom in on data.

Read the methods section of the study. The methods section of the study usually appears after the introduction and background section. “To me, the methods section is almost the most important part of any scientific paper,” says Aschwanden. “It’s amazing to me how often you read the design and the methods section, and anyone can see that it’s a flawed design. So just giving things a gut-level check can be really important.”

What’s the sample size? Not all good studies have large numbers of participants but pay attention to the claims a study makes with a small sample size. “If you have a small sample, you calibrate your claims to the things you can tell about those people and don’t make big claims based on a little bit of evidence,” says Bottesini.

But also remember that factors such as sample size and p-value are not “as clear cut as some journalists might assume,” says Wilner.

How representative of a population is the study sample? “If the study has a non-representative sample of, say, undergraduate students, and they’re making claims about the general population, that’s kind of a red flag,” says Bottesini. Aschwanden points to the acronym WEIRD, which stands for “Western, Educated, Industrialized, Rich, and Democratic,” and is used to highlight a lack of diversity in a sample. Studies based on such samples may not be generalizable to the entire population, she says.

Look at the p-value. Statistical significance is both confusing and controversial, but it’s important to consider. Read our tip sheet, “5 Things Journalists Need to Know About Statistical Significance,” to better understand it.

3. Talk to scientists not involved in the study.

If you’re not sure about the quality of a study, ask for help. “Talk to someone who is an expert in study design or statistics to make sure that [the study authors] use the appropriate statistics and that methods they use are appropriate because it’s amazing to me how often they’re not,” says Aschwanden.

Get an opinion from an outside expert. It’s always a good idea to present the study to other researchers in the field, who have no conflicts of interest and are not involved in the research you’re covering and get their opinion. “Don’t take scientists at their word. Look into it. Ask other scientists, preferably the ones who don’t have a conflict of interest with the research,” says Bottesini.

4. Remember that a single study is simply one piece of a growing body of evidence.

“I have a general rule that a single study doesn’t tell us very much; it just gives us proof of concept,” says Peters. “It gives us interesting ideas. It should be retested. We need an accumulation of evidence.”

Aschwanden says as a practice, she tries to avoid reporting stories about individual studies, with some exceptions such as very large, randomized controlled studies that have been underway for a long time and have a large number of participants. “I don’t want to say you never want to write a single-study story, but it always needs to be placed in the context of the rest of the evidence that we have available,” she says.

Wilner advises journalists to spend some time looking at the scope of research on the study’s specific topic and learn how it has been written about and studied up to that point.

“We would want science journalists to be reporting balance of evidence, and not focusing unduly on the findings that are just in front of them in a most recent study,” Wilner says. “And that’s a very difficult thing to as journalists to do because they’re being asked to make their article very newsy, so it’s a difficult balancing act, but we can try and push journalists to do more of that.”

5. Remind readers that science is always changing.

“Science is always two steps forward, one step back,” says Peters. Give the public a notion of uncertainty, she advises. “This is what we know today. It may change tomorrow, but this is the best science that we know of today.”

Aschwanden echoes the sentiment. “All scientific results are provisional, and we need to keep that in mind,” she says. “It doesn’t mean that we can’t know anything, but it’s very important that we don’t overstate things.”

Authors of a study published in PNAS in January analyzed more than 14,000 psychology papers and found that replication success rates differ widely by psychology subfields. That study also found that papers that could not be replicated received more initial press coverage than those that could. 

The authors note that the media “plays a significant role in creating the public’s image of science and democratizing knowledge, but it is often incentivized to report on counterintuitive and eye-catching results.”

Ideally, the news media would have a positive relationship with replication success rates in psychology, the authors of the PNAS study write. “Contrary to this ideal, however, we found a negative association between media coverage of a paper and the paper’s likelihood of replication success,” they write. “Therefore, deciding a paper’s merit based on its media coverage is unwise. It would be valuable for the media to remind the audience that new and novel scientific results are only food for thought before future replication confirms their robustness.”

    Our Verdict

    When comparing oat milk to almond milk, we picked the almond milk.

    Why?

    This one’s quite straightforward, and no, it’s not just our bias for almonds

    Rather, almonds contain a lot more vitamins and minerals, all of which usually make it into the milk.

    Oat milk is still a fine choice though, and has a very high soluble fiber content, which is great for your heart.

    Just make sure you get versions without added sugar or other unpleasantries! You can always make your own at home, too.

    So, no question/request too big or small

    ❝[About accidental scalding with water] Is cold water actually the best immediate treatment for a burn? Maybe there is something better, or something I should apply after the cold water.❞

    If this is a case of spilled tea or similar—as in your story, which (apologies) we clipped for brevity—indeed, cold running water is best, and nothing else should be needed. It’s up to you whether you want to invest the time based on the extent of the scalding, but 10 minutes is recommended to minimize tissue damage.

    If it’s a more severe scalding or burning, seek medical attention immediately. If it’s a burn to anywhere other than the airway, cold running water is still best for 10 minutes, but if you have to choose between that and professional medical attention, don’t delay the help.

    If it’s a burn you’ve given 10 minutes of cold running water and it still hurts and/or has blistered, cover it in a sterile, non-adhesive dressing that extends well beyond the visible burn (because the actual damage probably extends further, and you don’t want to find this out the hard way later). If the burn is to the face, do still irrigate but not cover it; wait for help.

    Do not apply any kind of cream, lotion, oil, etc. No matter how tempting, no matter where the burn is.

    All of the above also goes for splashed oil, chemical burns, and electrical burns too (but obviously, make sure to get away from the electricity first).

    Source: this ex-military writer was trained for this sort of thing and, suffice it to say, has dealt with more serious things than spilled tea before now.

  • 10 Simple Japanese Habits For Healthier & Longer Life

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    You don’t have to be Japanese or live in Okinawa to enjoy the benefits of healthy longevity. A lot of it comes down to simple habits:

    Easy to implement

    We’ll not keep the 10 habits a mystery; they are:

    1. Start the day with hot water: drinking hot water in the morning helps with hydration, warming the body, and aiding digestion.
    2. Enjoy a hearty breakfast: Japanese breakfasts are traditionally filling, nutritious, and help promote energy and longevity. Typical components include rice, miso soup, fish, and pickles.
    3. Take balanced meals: Japanese education emphasizes nutrition from a young age, promoting balanced meals with proteins, fiber, and vitamins & minerals.
    4. Enjoy fermented foods: fermented foods, such as nattō and soy-based condiments, support digestion, heart health, and the immune system.
    5. Drink green tea and matcha: both are rich in health benefits; preparing matcha mindfully adds a peaceful ritual to daily life too.
    6. Keep the “80% full” rule: “hara hachi bu” encourages eating until 80% full, which can improve longevity and, of course, prevent overeating.
    7. Use multiple small dishes: small servings and a variety of dishes help prevent overeating and ensure a diverse intake of nutrients.
    8. Gratitude before and after meals: saying “itadakimasu” and “gochisousama” promotes mindful eating, and afterwards, good digestion. Speaking Japanese is of course not the key factor here, but rather, do give yourself a moment of reflection before and after meals.
    9. Use vinegar in cooking: vinegar, often used in sushi rice and sauces like ponzu, adds flavor and offers health benefits, mostly pertaining to blood sugar balance.
    10. Eat slowly: Eating at a slower pace will improve digestion, and can enhance satiety and prevent accidentally overeating.

  • Common Hospital Blood Pressure Mistake (Don’t Let This Happen To You Or A Loved One)

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    There’s a major issue in healthcare, Dr. Suneel Dhand tells us, pertaining to the overtreatment of hypertension in hospitals. Here’s how to watch out for it and know when to question it:

    Under pressure

    When patients, particularly from older generations, are admitted to the hospital, their blood pressure often fluctuates due to illness, dehydration, and other factors. Despite this, they are often continued on their usual blood pressure medications, which can lead to dangerously low blood pressure.

    Why does this happen? The problem arises from rigid protocols that dictate stopping blood pressure medication only if systolic pressure is below a certain threshold, often 100. However, Dr. Dhand argues that 100 is already low*, and administering medication when blood pressure is close to this can cause it to drop dangerously lower

    *10almonds note: low for an adult, anyway, and especially for an older adult. To be clear: it’s not a bad thing! That is the average systolic blood pressure of a healthy teenager and it’s usually the opposite of a problem if we have that when older (indeed, this very healthy writer’s blood pressure averages 100/70, and suffice it to say, it’s been a long time since I was a teenager). But it does mean that we definitely don’t want to take medications to artificially lower it from there.

    Low blood pressure from overtreatment can lead to severe consequences, requiring emergency interventions to stabilize the patient.

    Dr. Dhand’s advice for patients and families is:

    • Ensure medication accuracy: make sure the medical team knows the correct blood pressure medications and dosages for you or your loved one.
    • Monitor vital signs: actively check blood pressure readings, especially if they are in the low 100s or even 110s, and discuss any medication concerns with the medical team.
    • Watch for symptoms of low blood pressure: be alert for symptoms like dizziness or weakness, which could indicate dangerously low blood pressure.

  • Antioxidant Matcha Snack Bars

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The antioxidants in this come not just from the matcha, but also the cacao nibs and chocolate, as well as lots of nutrients from the hazelnuts and cashews. If you’re allergic to nuts, we’ll give you substitutions that will change the nutritional profile (and flavor), but still work perfectly well and be healthy too.

    You will need

    For the base:

    • ⅔ cup roasted hazelnuts (if allergic, substitute dessicated coconut)
    • ⅔ cup chopped dates

    For the main part:

    • 1 cup raw cashews (if allergic, substitute raw coconut, chopped)
    • ½ cup almond milk (or your preferred milk of any kind)
    • ½ cup cacao nibs
    • 2 tbsp lime juice
    • 1 tbsp matcha powder
    • 1 tbsp maple syrup (omit if you don’t care for sweetness)

    For the topping (optional):

    • 2oz dark chocolate, melted (and if you like, tempered—but this isn’t necessary; it’ll just make it glossier if you do)
    • Spare cacao nibs, chopped nuts, or anything else you might want on there

    Method

    (we suggest you read everything at least once before doing anything)

    1) Blend the base ingredients in a food processor until it has a coarse sticky texture, but isn’t yet a paste or dough.

    2) Line a cake pan with baking paper and spread the base mix on the base; press it down to compact it a little and ensure it is flat. If there’s room, put this in the freezer while you do the next bit. If not, the fridge will suffice.

    3) Blend the main part ingredients apart from the cacao nibs, until smooth. Stir in the cacao nibs with a spoon.

    4) Spread the main part evenly over the base, and allow everything you’ve built (in this recipe, not in life in general) to chill in the fridge for at least 4 hours.

    5) Cut it into blocks of the size and shape you want to eat them, and (if adding the optional topping) separate the blocks slightly from each other, before drizzling with the chocolate topping. Put it back in the fridge to cool this too; an hour should be sufficient.

    6) Serve!

    Enjoy!

  • Super Gut – by Dr. William Davis

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    You may be wondering: what sets this book apart from the other gut health books we’ve reviewed? For this one, mostly it’s depth.

    This is the most scientifically dense book we’ve reviewed on gut health, so if you’re put off by that, this might not be one for you. However, you don’t need prior knowledge, as he does explain things as he goes. The advice in this book is not just the usual “gut health 101” stuff, either!

    A particular strength of this book is that it looks at a wide variety of gut- and gut-related disorders, and ways certain readers may need to do different things than others, to address those problems on the path to good gut health.

    The style, for all its hard science content, is quite sensationalist, and that may take some getting used to for non-Americans. However, it doesn’t affect the content!

    Bottom line: if you just want simple basic advice, then probably best to skip this one. However, if you are sincerely serious about gut health (or just like reading this sort of thing because learning is satisfying), then this book is packed with relevant and detailed information.

    Click here to check out Super Gut, and get to know and improve yours!
