I'm a PhD Candidate in Cognitive Science at UC San Diego. Through research, I try to better understand how metaphor shapes the way we perceive and think about the world.

Scientists Agree on Climate Change: A Gateway Belief


It doesn’t get much clearer. The Earth’s climate is warming. Humans are the reason. But how many people are actually aware of the scientific consensus on this issue?

Research by Sander van der Linden and colleagues shows that when people believe that scientists overwhelmingly agree about climate change, they increase their a) own beliefs in climate change and b) beliefs that humans are responsible. They feel c) more worried about climate change, and as a result of a, b, and c, they support public action to mitigate the effects of climate change.


At the beginning of the study, participants indicated the percentage of scientists they thought agree on global warming and they answered some questions about their own climate change beliefs. People then received a message about scientific consensus, which took the form either of a) a simple description, b) a pie chart, or c) a metaphorical comparison related to trusting engineers’ consensus about bridges (i.e., if 97% of engineers agreed that a bridge was unsafe, would you use it?) or doctors’ consensus about illness. All the messages included the info that “97 % of climate scientists have concluded that human-caused climate change is happening.”

Then participants again indicated what percent of scientists they thought agree on global warming and answered questions about their own beliefs. All messages “worked,” in the sense that people perceived greater scientific agreement after the messages telling them that 97% of scientists agree than if they hadn’t read anything about the consensus at all (though the simple description and pie chart were more effective than the metaphor. People shifted their climate change beliefs more after encountering one of the more straightforward messages than the more complex metaphor. Great food for thought, as many science communicators insert metaphors wherever they can).

Of course, having people believe that there’s strong scientific consensus about climate is only one step toward the larger goal of having them endorse actions that mitigate the effects of climate change. But in follow-up analyses, the researchers identified that perceiving scientific agreement is a gateway belief: believing that scientists agree about global warming led to other beliefs, ones that get us closer to the goal of actions in favor of mitigating climate change. Specifically, it led to greater belief that climate change was real, human-caused, and worrisome. These beliefs, in turn, led to greater support for public action against climate change. It’s often hard to know what leads to what, especially when it comes to beliefs we keep hidden in our own heads, but with some semi-fancy math, these researchers quantified those relationships.

These studies have some clear takeaways for science communicators (especially when communicating about climate change — but maybe these ideas apply to other topics too — need more research!)

  • Emphasize scientific consensus, that an overwhelming percentage of scientists agree that climate change is a real problem caused by human activity.
  • Don’t worry so much about immediately pushing for public action against climate change. When people understand that scientists agree, they come to agree themselves that climate change is a problem that should be addressed, and THEN they come to support public action. Be careful about skipping steps.

At the same time, there’s not only one right way to communicate about climate change. There are truly effective ways, ineffective and potentially backfiring ways, and many in between. There aren’t cut-and-dry rules because every audience is unique, and taking the audience into account — their beliefs, values, and past experiences, for example — is crucial. But this work sheds light on communication strategies that are probably pretty far toward the “truly effective” end of the ways-to-communicate-climate-change continuum.

Only one eye on the prize

From my journal, November 2015, my third year in grad school:


That gray silhouette is my mom. I call her most days, but sometimes we text instead. We probably spend half our time talking about daily life — yoga, work, what we’re cooking for dinner — and the other half of our time talking about our thoughts. My thoughts are often future-oriented. For example, I talk about trips that are scheduled for 6 months out as if they’re tomorrow because the future just always feels so imminent. I also talk a lot about my professional future, even though I’m not even sure what my professional goals are. I’m constantly asking myself (internally and aloud), what I can do to secure that all-fulfilling (and elusive) job that’ll allow me to positively impact the world, stay challenged, and help pay the bills for a comfortable home in a stimulating city.

My mom listens so much (thanks, Mom!). She validates my ideas, suggests other things to consider, and maybe most importantly, reminds me that the present is pretty great too. Goals are crucial, and we attain them by having our “eye on the prize.” But luckily we have two eyes. Our biological eyes may not be able to focus on two different things, but our metaphorical ones can. We can keep one eye on the prize while focusing the other on the present. When I do that, I remember that this current stage of my life — 4th year of my PhD, exploring different ways that metaphor shapes thought, in a mind-blowing Cognitive Science department in America’s Finest City — is pretty darn amazing.

For a while, this was the prize that I kept my eye on. When I was an undergrad at Vassar, as I started to learn more about language and cognitive science and more about research, I set my eye on graduate school, and soon after set my eye on THIS graduate school. I wanted to be accepted so much that I cried. Then I was accepted. I came to UCSD and started grad school. In typical human fashion, as the former prize became the present, I looked forward again to the next prize. Even though that next prize is still foggy in my mind, I know there must be a prize there, and I know I want to position myself as best as possible to attain it. So one eye will stay there. But as for the other…

Metaphors for creativity: using our bodies for problem solving

It can be hard to be creative. Yet so many of our endeavors demand creativity. Creating art or writing a screenplay are obvious examples that demand creativity, but so do less obvious activities like creating a lesson plan for a high school history class, creating ads for a political campaign, or coming up with a bedtime story for your kid. What kinds of advice do we give each other for being creative? And does our advice actually help us come up with clever solutions or novel ideas.

To test whether the “on the one hand… on the other hand” metaphor is embodied, participants were asked to come up with novel uses for a university building complex. In round one, they generated as many ideas as possible while holding out their right hand and keeping their left behind their back. In round two, they were asked to come up with additional novel suggestions for this same question. Some participants kept their right hand out and left behind their backs, while others now put the right behind their back and held their left out. This second group of participants embodied the “on the one hand…on the other hand” metaphor, while the first did not.

Accordingly, those who did use both hands came up with more potential solutions overall, as well as more flexible and original ideas (as rated by independent coders) than those who only used one hand. Enacting this common metaphor for creativity (without actually saying or hearing “on one hand… and on the other hand”) actually fostered more and better solutions.

They also explored the effects of embodying the metaphorical advice to “think outside the box.” For this experiment, the researchers created a box that was 5 feet by 5 feet so that one person could comfortably sit in it (I wish there was an image of this!). They told participants they were studying the effects of different work environments, and while either sitting inside or outside the box, participants did a common creativity task called a Remote Association Task. For that task, participants receive 3 words (like “measure,” “worm,” and “video”), and have to think of a fourth word that can be combined with the previous three to make real words (in the example case, “tape” –> “tape measure,” “tapeworm,” and “video tape”). People who did this task while sitting outside the box came up with more correct answers than those who did it while sitting inside the box.

Literally thinking outside the box helped people figuratively think outside the box.

From this work, you could take away the lessons to hold both your hands out and make sure you’re sitting outside a big box when trying to do creative work. And maybe those strategies would help, but offering them was not the purpose of this paper. Instead, the authors focus on their contribution to the massive undertaking that is understanding the human mind, especially how we engage in such complicated processes as creativity. They point out that our bodies and minds are linked in ways that affect how we generate knowledge. By doing so, they shine light on one of the phenomena that make humans the endlessly fascinating creatures that we are.

Check out the full study to read about follow-up studies, and how different metaphors affect divergent thinking (coming up with many solutions) vs. convergent thinking (using different pieces of knowledge to settle on the one correct answer).

Cross-Country Love: Our Academic-Army Marriage

I live in San Diego. My husband Steven lives in San Antonio. We’ve been a long-distance couple since I began grad school (and he began working as on officer in the US Army). San Diego-San Antonio is actually the closest we’ve ever been to each other: it took at least two flights plus a few hours in the car to see each other when he lived in Kansas, and visits were not possible when he was deployed in Kuwait. We’re grateful that a non-stop flight can take us from one city to the other, but it’s far from ideal.

We were even more grateful that I was able to arrange my teaching and research so I could spend two months in San Antonio recently.

We’d been married for over a year, and the two months we recently spent together were our first opportunity to live together. It wasn’t a test of whether we’re truly compatible (we are, we always have been), and it wasn’t a vacation. We did real life (albeit a different real life than we’re used to), and we did it while living under the same roof. It was wonderful.


Here we’re at San Antonio’s Riverwalk, decked out for Christmas.

In the mornings, I made his breakfast while waiting for my own tea to brew. In the evenings, he tucked me in as tightly as possible, a practice we began referring to as Burrito Rose. We went to the gym together and made jigsaw puzzles. I cooked most dinners, he cleaned most dishes. We spied on neighbors, I gave him haircuts, he did our laundry. We settled into a precious rhythm, and the two months were wonderful for the person at my core.

For my academic mind, though, they left something to be desired. As I expected, working remotely and Skyping into the necessary meetings was a little boring. But this was a small price to pay for the freedom of working from a location that strengthened my relationship with Steven. The time in San Antonio helped me realize how much I prioritize freedom to work on what I want, when I want, where I want, but I also really value working with other smart people. Having little imposed structure to my workdays and fewer obligations to fulfill than normal allowed me time and space to reflect on my values and how they’ll factor into priorities for my career, or at least for my next career step. I asked myself, do I really like research that much? But how much does this submersion in relatively isolated research reflect what a research career would be like? How important is geography to me? How much money is important to me? How much free time do I need? Should I just graduate and move on with my life? Or should I shirk the subconscious sense that external signs of “progress” are to be constantly striven for?

I’m so grateful that I could continue to work while spending two months with Steven. We probably benefitted more than we had anticipated, and I proved to myself that I can be productive while working remotely. I’ll be back there soon, and someday home will actually be the same place for both of us.

Reframing the war on science

America’s kind of tense right now. Leading up to and following the November 2016 election, there’s a lot of talk of “the two Americas” and “the Divided States of America.” Americans are divided on a lot of issues, including scientific topics like vaccine safety and global warming. To many, it’s surprising that we disagree about these things because according to scientists who research these topics, there are no debates at all: vaccines do not cause autism and humans are responsible for global warming

At the same time, the current administration in the US has sent numerous messages that they devalue science (for example, by censoring scientists at organizations like the USA and EPA and establishing a Committee on Vaccine Safety). Actions like these seem to be only fueling the divided science beliefs.

In response, many people have declared that we’re in a war on science: This idea is expressed in headlines like Facts are the reason science is losing the current war on reason, How the Anti-Vaxxers are Winning, and documentary titles like The Vaccine War. (There are so many pieces that talk about the war on science).

Scientific American

I’m a PhD student in Cognitive Science, a firm believer in the scientific method and basing beliefs and actions on evidence. I highly value scientific funding, vaccinations, and measures that reduce the effects of climate change. As Americans, we have freedom of speech, and we should exercise that freedom to speak up when scientific knowledge and interests are being trampled on. I agree with the ideas expressed in blog posts like The War on Facts is a War on Democracy and I’m a Scientist. This is what I’ll Fight for and many of the ideas that continuously populate threads on Twitter like #defendscience and #resist. But I’m much less enthusiastic about the widespread use of a war metaphor to get those ideas across.

Here’s why.

Metaphors shape thought

The metaphors we use to describe complex social problems actually shape the way we think about them. For example, when crime was described as a beast ravaging a town, people tended to suggest harsh law enforcement policies — similar to how they’d likely react to a literal beast ravaging their town. On the other hand, when that same crime was described as a virus, people suggested fewer harsh enforcement policies. Instead, they turned their focus to curing the town of problems that may underlie the crime, like improving education and welfare services.

People make inferences in line with the metaphors used to describe complex issues, so it’s important to reflect on what the war on science implies. It does have some helpful implications. Wars are serious, and often require urgent action. These are probably the messages that those who perpetuate the war on science want us to infer, even if not consciously.

But the war also suggests that there are enemies and casualties. There are two sides locked in combat, and neither will back down until they win (or they’re decimated). I like this quote from A Gentleman in Moscow, a novel I just happened to be reading while working on this post: After all, in the midst of armed conflicts, facts are bound to be just as susceptible to injury as ships and men, if not more so. In other words, we sometimes do stupid things in wars. We shirk thoughtfulness and conscientiousness, and instead we just fight. As I see it, our current political situation (for lack of a better word) needs all the thoughtfulness and conscientiousness we can give it.  

I recently expressed my concern in a conversation on Twitter:

The war metaphor challenges those who are not already on the “side” of science. It tells them they’re the enemy. When people feel that they’re being attacked, even idealistically, they’re likely to strengthen their stance and gear up to fight back. No matter how many scientists tweet about science or participate in the March for Science on Earth Day, people who have found themselves on the “anti-science” side of this war are not going to decide all of a sudden that climate change must be real after all or that they should rush their kids to the pediatrician for overdue vaccines (especially if we tell them we’re marching to fight the war on science!). People who have already been labeled as the enemy of science may as well go out and buy a new gas guzzler and decide that their kids are just fine without vaccines.

Others have already pointed out that actions like the science march are already in jeopardy of isolating anti-science proponents as opponents (for example see  Daniel Engber’s piece for Slate and Robert Young’s in the New York Times). Using war metaphors has the potential to only hammer that point home.

Alternative frames?

If we want to stop thinking about ourselves as engaged in a war on science, we need an alternative. Proponents of and believers in science are experiencing a sort of struggle, but it doesn’t have to be a fight between the left and right, Democrats and Republicans, Coastal Elite and Middle America. Maybe we can reframe the situation as a challenge that unites all humans. Science communicators want to share how important it is to address climate change and to have children vaccinated for the good of all people. We can all be on the same side, working to better the world we live in, and it’s important that we convey that message in our communications.

Referring to the movie Hidden Figures, NPR blogger Marcelo Gleiser points out that if there is a central lesson in the movie, it is that united we win; that what makes America great is not segregation and intolerance, but openness and inclusiveness.

I considered the possibility that guiding people to trust empirical evidence and the scientific process might be better framed as a puzzle — a challenge, no doubt, but at least everyone’s working toward a common goal.

Marisa makes a really important point. The peacekeeper in me would love a frame that emphasizes hey, guys! We’re all in this together!, but that ship may have already sailed. At this point, it’s important not to downplay the gravity of discrediting and distrusting science. This is not a game.


I’ve had quite a few conversations on the war on science, but I still don’t have a one-size-fits-all framing suggestion for talking about America’s disconnect in belief in science. But when we’re considering talking about this issue as a war, it’ll be helpful to step back and assess our goals and the potential consequences of the words we use.

Right now, there are deep social and political divides in American society — and though it’s crucial to stand up for what we believe in (especially science and facts!), we should be careful about taking up arms in a war on science that might deepen those divides. 

I welcome other comments on the framing of the war on science. Do you find the war helpful? Why? Are there other frames we could use to avoid deepening ideological divides?

Just start

From my journal, halfway through my third year, April, 2016. On beginning my dissertation proposal.

For many people, a dissertation only encompasses a piece of your grad school work. Knowing that, how do I know what the right scope is for a dissertation proposal?

Feelings of paralysis, which I’m not very familiar with.

My advisor says, just start. Write an outline. Write a second one, trying something different. Keep trying things.

Less than a year later, I’ve been starting to talk and think about breaking ground on my actual dissertation. Quickly, I start to feel similar feelings: but where do I start? 

I really enjoy Alain de Botton‘s website The Book of Life. While wondering what projects to write about for my dissertation proposal, I came across a helpful post: How to dare to begin. He points out: “In general, we can only start working when the fear of not doing anything finally exceeds the fear of doing it badly.”

He advises people to visit the studio, not the gallery. The gallery houses polished works, while the studio houses those in progress. This is hard to do for academic writing because people keep their unpolished work hidden, but it’s important to remember that when you’re reading the published work, you’re seeing the gallery products. But they all began in a studio.

de Botton also reminds readers that “the imperfect can still be very good, noble and admirable. For something to be loved and valued, it really isn’t necessary for it to be perfect.” This especially resonates with me right now because I often hear that “the best dissertation is a done dissertation.” 

Next, remember that in the grand scheme of things, like all human life on this planet, the thing you’re afraid to start is pretty darn small in scope. Actually, it basically doesn’t matter at all. And finally, scrutinize your fears. If you’ve taken his advice up to here, you’ll probably realize that your fears don’t have a leg to stand on.

Once you start, you just have to make sure you Keep Going.

Communicating climate change: Focus on the framing, not just the facts

Humans are currently in a war against global warming. Or is it a race against global warming? Or maybe it’s just a problem we have to deal with? The Conversation

If you already consider climate change a pressing issue, you might not think carefully about the way you talk about it – regardless of how you discuss it, you already think of global warming as a problem. But the way we talk about climate change affects the way people think about it.

For scientific evidence to shape people’s actions – both personal behaviors like recycling and choices on policies to vote for – it’s crucial that science be communicated to the public effectively. Social scientists have been increasingly studying the science of science communication, to better understand what does and does not work for discussing different scientific topics. It turns out the language you use and how you frame the discussion can make a big difference.

The paradox of science communication

“Never have human societies known so much about mitigating the dangers they faced but agreed so little about what they collectively know,” writes Yale law professor Dan Kahan, a leading researcher in the science of science communication.

Kahan’s work shows that just because someone has scientific knowledge, he or she won’t necessarily hold science-supported beliefs about controversial topics like global warming, private gun possession or fracking.

Instead, beliefs are shaped by the social groups people consider themselves to be a part of. We’re all simultaneously members of many social groups – based, for example, on political or religious affiliation, occupation or sexuality. If people are confronted with scientific evidence that seems to attack their group’s values, they’re likely to become defensive. They may consider the evidence they’ve encountered to be flawed, and strengthen their conviction in their prior beliefs.

Unfortunately, scientific evidence does sometimes contradict some groups’ values. For example, some religious people trust a strict reading of the Bible: God said there would be four seasons, and hot and cold, so they don’t worry about the patterns in climate that alarm scientists. In cases like this one, how can communicators get their message across?

A growing body of research suggests that instead of bombarding people with piles of evidence, science communicators can focus more on how they present it. The problem isn’t that people haven’t been given enough facts. It’s that they haven’t been given facts in the right ways. Researchers often refer to this packaging as framing. Just as picture frames enhance and draw attention to parts of an image inside, linguistic frames can do the same with ideas.

One framing technique Kahan encourages is disentangling facts from people’s identities. Biologist Andrew Thaler describes one way of doing so in a post called “When I talk about climate change, I don’t talk about science.” Instead, he talks about things that are important to his audiences, such as fishing, flooding, farming, faith and the future. These issues that matter to the people with whom he’s communicating become an entry into discussing global warming. Now they can see scientific evidence as important to their social group identity, not contradictory to it.

Let me rephrase that

Metaphors also provide frames for talking about climate change. Recent work by psychologists Stephen Flusberg, Paul Thibodeau and Teenie Matlock suggests that the metaphors we use to describe global warming can influence people’s beliefs and actions.

Ready for combat?
Thomas Hawk, CC BY-NC

The researchers asked 3,000 Americans on an online platform to read a short fictional news article about climate change. The articles were exactly the same, but they used different metaphors: One referred to the “war against” and another to the “race against” climate change. For example, each article included phrases about the U.S. seeking to either “combat” (war) or “go after” (race) excessive energy use.

After reading just one of these passages, participants answered questions about their global warming beliefs, like how serious global warming is and whether they would be willing to engage in more pro-environmental behaviors.

Metaphors mattered. Reading about the “war” against global warming led to greater agreement with scientific evidence showing it is real and human-caused. This group of participants indicated more urgency for reducing emissions, believed global warming poses a greater risk and responded that they were more willing to change their behaviors to reduce their carbon footprint than people who read about the “race” against global warming.

The only difference between the articles that participants read was the metaphors they included. Why would reading about a war rather than a race affect people’s beliefs about climate change in such important ways?

The researchers suggest that when we encounter war metaphors, we are reminded (though not always consciously) of other war-related concepts like death, destruction, opposition and struggle. These concepts affect our emotions and remind us of the negative feelings and consequences of defeat. With those war-related thoughts in mind, we may be motivated to avoid losing. If we have these war thoughts swimming around in our minds when we think about global warming, we’re more likely to believe it’s important to defeat the opponent, which, in this case, is global warming.

There are other analogies that are good at conveying the causes and consequences for global warming. Work by psychologists Kaitlin Raimi, Paul Stern and Alexander Maki suggests it helps to point out how global warming is similar to many medical diseases. For both, risks are often caused or aggravated by human behaviors, the processes are often progressive, they produce symptoms outside the normal range of past experiences, there are uncertainties in the prognosis of future events, treatment often involves trade-offs or side effects, it’s usually most effective to treat the underlying problem instead of just alleviating symptoms and they’re hard to reverse.

People who read the medical disease analogy for climate change were more likely to agree with the science-backed explanations for global warming causes and consequences than those who read a different analogy or no analogy at all.

Golden past or rosy future?

Climate change messages can also be framed by focusing on different time periods. Social psychologists Matthew Baldwin and Joris Lammers asked people to read either a past-focused climate change message (like “Looking back to our nation’s past… there was less traffic on the road”) or a similar future-focused message (“Looking forward to our nation’s future… there is increasing traffic on the road”).

The researchers found that self-identified conservatives, who tend to resist climate change messages more than liberals, agreed that we should change how we interact with the planet more after reading the past-focused passage. Liberals, on the other hand, reported liking the future-focused frame better, but the frames had no influence on their environmental attitudes.

And the frames didn’t have to be words. Conservatives also shifted their beliefs to be more pro-environmental after seeing past-focused images (satellite images that progressed from the past to today) more than after seeing future-focused ones (satellite images that progressed from today into the future). Liberals showed no differences in their attitudes after seeing the two frames.

Many climate change messages focus on the potential future consequences of not addressing climate change now. This research on time-framing suggests that such a forward-looking message may in fact be unproductive for those who already tend to resist the idea.

There’s no one-size-fits-all frame for motivating people to care about climate change. Communicators need to know their audience and anticipate their reactions to different messages. When in doubt, though, these studies suggest science communicators might want to bring out the big guns and encourage people to fire away in this war on climate change, while reminding them how wonderful the Earth used to be before our universal opponent began attacking full force.
