Artistic representations of data can help bridge the US political divide over climate change

Visual art has been used to revamp the portrayal of climate change with the aims of engaging emotions and expanding nonexperts ’ psychological capacity to perceive its relevance. However, empirical evidence supporting the effectiveness of artistic representation of data as a tool for public communication is lacking. Using controlled experiments with two national samples of U

espite the passing of the Inflation Reduction Act, designed to curb greenhouse gas emissions, the U.S. public is still divided over how to address the challenges caused by climate change 1 .Opinion gaps have been widening between liberals and conservatives regarding the urgency to act and the policy direction(s) the country should take 1 .Many existing efforts attempt to mitigate the opinion gap by using data and scientific graphs to relay the reality of climate change [2][3][4] .Although data graphs confront viewers with imputable evidence, they may signal an intent of reasoning and heighten the skeptics' biased processing of attitudinally incongruent information 5,6 .Numerous calls have been made to infuse data-based communication with emotions and portrayals of shared experiences to unite individuals who may otherwise disagree 7 .
In response, scientist and artists in the U.S. have revamped graphical representations of climate change with visual art.For instance, line graphs of soaring temperatures were incorporated into watercolor portrayals of mountains and glaciers, and a chart showing the trend in hurricane strength was transformed into abstract art with contrasting colors 8,9 .The assumption behind artworks like these is that they can help "meet the imaginative deficit of scientific data", leading scientist-artists to disseminate the works via social media in hopes of raising public awareness 10 .The #ShowYourStripes campaign initiated by the UK climate scientist Ed Hawkins on social media, for example, allows residents in 179 U.S. cities and other places around the globe to transform local, century-long temperature data into a series of blue-to-red colored warming stripes.As seen on buildings, streets, scarfs, masks, and the cover of Greta Thunberg's "The Climate Book", the artistic visualization has become an iconic symbol that is widely used to encourage local climate action 11 .
However, as artistic representations of climate data proliferate, questions remain as to whether they are more effective than scientific data graphs in conveying factual evidence and boosting public trust in the accompanying information.Despite their prevalence, artistic visualizations can fail if their abstraction trumps clarity 12 .Viewers may beautify, trivialize, or even misinterpret the delineated issue when artistic portrayals make data obscure 13 .Those who lack interest or appreciation for visual art may feel particularly distanced or distracted by such a medium 14,15 .
Nonetheless, members of the scientific community commonly regard visual art as a beneficial tool for communicating their work 16 .As Nature found in a recent poll with its readers affiliated with various scientific disciplines (N = 350), almost all participants indicated they would consider collaborating with artists in public outreach efforts, believing that it would help "make emotional connections that enhance learning" 17 .Although studies have found that artistic visualizations can elicit strong emotions [18][19][20] , little evidence exists to show how they may help people retain knowledge better than data graphs as a more established visual language of science.It is also unclear if the use of artistic visualizations may diminish viewers' perceived credibility of the accompanied information as many people may lack trust in artists when it comes to science 12 .
Using an online controlled experiment with a non-probability sample of U.S. adults (N = 319), this study examined how artistic representations of climate data, as compared to scientific graphs, might influence viewers' emotions and recall of climate change information.We also investigated whether artistic representations of data were perceived as more or less credible than scientific graphs and studied how the art's impact on emotions might vary as a function of one's interest in visual art.
More importantly, we questioned if enhancing the data-based communication of climate change with visual art could help bridge the political divide on climate change.Liberal Democrats and conservative Republicans in the U.S. tend to interpret climate data through a political lens and use the provided data to justify their preexisting beliefs 4 .For example, an eye-tracking study found that when looking at a line graph featuring global temperature change, liberals paid more attention to the rising phase than the flat phase of the temperature curve while the opposite was true for conservatives 21 .However, liberals and conservatives did not differ in their attention when the graph was framed as unrelated to climate change 21 .As political motivations drive selective attention to graphical evidence, overreliance on data graphs for communicating climate change may exacerbate political division on this issue.
Artistic representations of data, nonetheless, can potentially attenuate the polarizing effect of data graphs by engaging certain emotions that mitigate motivated attention and reasoning.Specifically, avoidance emotions, such as anxiety, can "promote the consideration of opposing views and a willingness to compromise", regardless of the accuracy of the presented view 22,23 .For example, when experiencing anxiety, partisans were more likely to accept corrections to politically congruent misinformation from the opposing party 24 .As with other forms of climate art, artistic representations of data can evoke anxiety or similar emotions by portraying the tangible reality of climate change 18,25 .Such emotional experiences may motivate spectators to reassess the visualized data that contradicts their beliefs and reduce the perceived distance to climate change 26 .Although some anecdotal evidence exists to suggest this possibility 27,28 , empirical evidence is lacking.We hence raised a research question asking if individuals would be less politically polarized in their perceived relevance of climate change when viewing artistic visualizations than when viewing informationally equivalent data graphs.
In addition, priming individuals with non-directional goals, such as to comprehend or achieve accuracy, can help them autonomously engage with the shown information instead of defaulting to biased reasoning 29,30 .For instance, when being asked to thoughtfully evaluate a piece of graphical evidence (e.g., a line graph indicating the loss of Arctic ice), conservatives were more likely to agree that climate change was serious than when reading an article unrelated to environmental issues 4 .In a similar vein, individuals judged art pieces to be "more powerful, challenging, and personally meaningful" when asked to write interpretations of them 31 .We wondered if offering reflective primes, such as prompting viewers to reflect on the meaning of and emotions evoked by the shown visuals, would interfere with the proposed depolarizing effect of artistic visualizations.In other words, do artistic visualizations still mitigate the polarizing effect that could otherwise be exacerbated by data graphs when viewers are prompted to ponder what they have seen and felt from the images?A follow-up experiment with a non-probability adult sample (N = 352) was conducted to answer this question.
The art piece chosen as the experimental stimulus was created by Diane Burko, an American painter and photographer who exhibited her climate-themed paintings at various venues, including the National Academy of Sciences, Engineering, and Medicine and the Bernstein Gallery at Princeton University.The piece, titled Summer Heat, 2020, was selected due to its exemplary integration of fine art and a recognizable scientific graph (Fig. 1).The embedded graph references the renowned Keeling curve, which shows the accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory since 1958 32 .By having a simplified version of the Keeling curve juxtaposed with melted glaciers, the artwork conveys that "the causes and effects of climate change are crashing into each other" 33 .The red-colored map of Europe also reminds viewers of the recordbreaking heat that hit the area in 2020.
Based on Burko's art piece and the original Keeling curve, we created a 2 (artistic representation vs. data graph) * 2 (detailed graph vs. simplified graph) experimental design that allowed us to examine the effect of the visual format without being confounded by the distinct level of data specificity shown in the stimuli.For each condition, we first showed one standalone image (Fig. 1) to prompt reflections and gauge evoked emotions and then displayed one mockup Instagram post embedding the same image and a caption drafted by the authors (Fig. 2).With two billion active users, Instagram has expanded the collaborative space between art and science 34 , allowing scientist-artists to reach out to audiences that are less frequent visitors of science museums and art galleries 35,36 .The ecological validity of the stimuli would be enhanced by such a setup.We then measured information recall, perceived credibility, and perceived relevance of climate change after showing the mockup Instagram posts.
The study found that artistic representations of data elicited stronger emotional responses than data graphs.Although participants with a lower level of art interest reported stronger negative emotions from data graphs, those with a higher level of art interest tended to perceive stronger negative emotions from the artistic visualizations.Interestingly, both data graphs and artistic visualizations were perceived as equally credible by participants.When primed to reflect on the meaning and emotions evoked by the visuals, participants were less politically polarized in their perceived relevance of climate change when viewing artistic visualizations than when viewing data graphs alone.

Results
Artistic representations of data evoked stronger positive emotions than data graphs.Participants were recruited in April 2022 through online panels provided by Forthright, a research panel available through Bovitz, Inc. Upon passing the inclusion criteria (i.e., having visited Instagram in the past) and offering consent to participate, participants were randomly assigned to four treatment groups and completed an online survey that lasted ~15 min.The study received approval from the University of Wisconsin-Madison Institutional Review Board (ID: 2022-0232).
Results of the ANOVA (see Supplementary Table 1) and post hoc comparisons showed that artistic representations evoked stronger positive emotions than data graphs as the main effect of art was significant, F (1, 316) = 8.16, p = 0.005, η 2 = 0.025.Further, the stimuli with detailed graphs elicited stronger negative emotions than the ones with simplified graphs as the main effect of detailed was significant, F (1, 316) = 13.21,p = 0.000, η 2 = 0.04 (see Supplementary Table 2).In addition, the original art piece elicited the highest positive emotions (mean 2.17, s.d.1.06), whereas the edited data graph (i.e., the one without any label, title, or numeric scale) elicited the lowest levels of positive emotions (mean 1.54, s.d.0.82) and negative emotions (mean 1.59, s.d.0.77) (Fig. 3).
Individuals interested in visual art were more likely to perceive negative emotions from artistic visualizations.In addition, we wondered if the emotional impact of artistic visualizations would vary for those with different levels of interest in visual art.Art interest was measured with the mean of five items on individuals' self-reported interest in visual art (Cronbach's alpha = 0.89, mean 4.35, s.d.1.36).Two interaction terms were created and entered in the analysis of covariance (ANCOVA) models to examine how the effect of artistic representation on positive and negative emotions may vary as a function of art interest (see Supplementary Tables 3 and 4).Results suggested that the interaction term was only significant when predicting negative emotions, F (1, 314) = 7.14, p = 0.008, η 2 = 0.022.Although data graphs evoked stronger negative emotions than artistic visualizations among people with a lower level of art interest, those with a higher level of art interest tended to perceive stronger negative emotions from the artistic visualizations than from data graphs (Fig. 4).
Posts containing artistic visualizations were perceived to be as memorable and credible as those containing data graphs.Post exposure to the mockup Instagram posts, participants answered a series of multiple-choice questions testing their recall of the caption text.We then recoded each answer into correct (coded as 1) and incorrect (coded as 0) and used the sum of correct answers to measure participants' information recall (KR-20 = 0.63, mean 2.89, s.d.1.56).The ANOVA results based on a combination of both  sub-samples suggested that the main effect of art on information recall was only marginally significant, F (1, 668) = 4.26, p = 0.039 (see Supplementary Table 5).Furthermore, we measured participants' perceived credibility of the Instagram posts with six items (Cronbach's alpha = 0.85, mean 4.70, s.d.1.08).Results of the ANOVA indicated that the posts containing artistic visualizations were perceived as credible as the ones containing data graphs as the main effect of art was not significant, F (1, 668) = 0.39, p = 0.535 (see Supplementary Table 6).
Prompting reflection on artistic visualizations mitigates political division on the perceived relevance of climate change.Lastly, we wondered if participants' perceived of climate change would be less polarized along political lines when viewing artistic visualizations than when viewing data graphs.Political leaning was measured by an index combining partisanship and political ideology.Perceived relevance of climate change was measured by three items (Cronbach's alpha = 0.87, mean 4.77, s.d.1.47).To examine how the relationship between political leaning and perceived relevance of climate change would vary for those who received different stimuli, we created an interaction term multiplying political leaning and a dichotomous variable contrasting the artistic and graphical treatments.Results of the ANCOVA showed that the interaction term was significant, F (1, 314) = 8.14, p = 0.005, η 2 = 0.025 (see Supplementary Table 7).The relationship between political leaning and perceived relevance of climate change was stronger among participants who viewed data graphs than among those who viewed artistic visualizations (Fig. 5a).In other words, participants were less politically polarized in their perceived relevance of climate change when viewing artistic visualizations than when viewing data graphs.
As shown in Fig. 5, this effect disappeared when participants were not primed to reflect on the meaning of and emotions evoked by the shown visuals (Fig. 5b).We duplicated the experimental design and recruited another non-probability sample using the same procedure (N = 352) in August 2022 to examine the potential role of a reflective prime in moderating the depolarizing effect of artistic visualizations.In the follow-up study, participants only received the mockup Instagram posts without viewing the stand-alone images first or answering any reflective question.Results showed that the relationship between political leaning and perceived relevance of climate change did not vary for those assigned to different groups as the interaction term was insignificant, F (1, 347) = 0.10, p = 0.76 (see Supplementary Table 8).

Discussion
Scientific data visualizations, such as the figures and charts presented in Al Gore's 2006 documentary "An Inconvenient Truth", and the disputed "hockey stick" graph, have merged as powerful symbols that fuel popular debates surrounding climate change 37 .However, they may not be efficacious as communication devices for unifying an increasingly divided public who has been repeatedly shown to ignore or devalue evidence that contradicts what they believe 30 .An artistic revamping of scientific graphs, nevertheless, could enrich the narrative inherent to data with emotions while expanding the viewers' psychological capacity to conceive of their position within larger ecologies.
Using controlled experiments and national samples of U.S. adults, this study offers pioneering evidence that artistic visualizations can be more impactful than data graphs in conveying the relevance of climate change to lay audiences with diverse values and interests.Our findings not only inform ongoing conversations about how science and art can work together to reckon with the impending environmental crisis, but they also suggest new opportunities for practitioners and researchers in climate science, communication, environmental humanities, psychology, and sociology to continue collaborative, interdisciplinary work in this area.
Artistic representations of data, as with other forms of climate art, can evoke strong emotions.Interestingly, the chosen art piece elicited more positive emotions than the comparable data graphs despite the negative valence intended by the artist.This could be in part due to the esthetically pleasing experience associated with art appraisal in general and the distanced perspective that the study participants have adopted for art reception (i.e., viewing art as part of a paid study) 38 .Nonetheless, participants with higher levels of interest in visual art were more likely to feel negative emotions from the artistic pieces.As negative emotions can function as prerequisites for meaning making related to art 38 , spectators with higher level of art interest may obtain richer interpretations from the shown art than those with lower interest.It is imperative for scientist-artists to be aware of audience differences and not assume homogenous emotional or cognitive responses to their work.
Nonetheless, when appraised in-person, climate change art can evoke distinct emotions as a function of various (artistic) features, including color, depicted content, even the size of the artwork or where it is installed 18 .Therefore, the findings obtained from one piece of artwork created by one American artist may not be generalizable to all climate change art.Future research should expand on the findings of this study and further explore how different types of visual art-created by other scientists and artists-can increase the perceived relevance of climate change for people living in countries other than the U.S. As artistic representations of data have been increasingly created and used to encourage pro-climate actions around the world 18 , it is imperative to investigate how this innovative approach of public-facing communication might work, for instance, in some of the Global South countries that are more vulnerable to the risks of climate change.
Despite the potential lack of global generalizability of our results, it should be emphasized that artistic representations have been consistently perceived as more emotionally positive than equivalent non-art pieces.For example, when viewing 80 pieces of fine paintings vs. commercial visuals, a group of Asian nonexperts reported higher levels of positive emotions when viewing the art 39 .Future studies should create or select a diverse set of comparable artistic and graphical representations of climate change data not only to examine its emotional and cognitive effects, but also to identify the specific characteristics that are associated with certain responses.An evidence-based understanding of such relationships will inform future practice that leverages both art and science to facilitate public engagement with climate change.
Relatedly, the observed effect might not be exclusively attributable to the artistic format.Noticeably, the painting stimuli contained complementary visual elements (e.g., the map of Europe, melted glaciers, etc.) that were not present in the data graphs.The results thus do not preclude the possibility that combining multiple non-artistic representations of the shown elements may elicit similar responses as the artwork.Future studies should consider using experimental stimuli that only vary in the visual format to rule out this possibility.Research along this line will also contribute additional insights into how a combined use of different forms of visual discourses may enhance the data-based communication of climate change.
Although previous research has suggested that artistic and abstract representations may lack effectiveness as visual aids for learning 12 , we did not find empirical support for such concern.Participants reported no significant difference in their perceived credibility or recall of the shown information accompanied by distinct visual stimuli.Nonetheless, a qualitative interview with 11 citizens living in the Netherlands observed that while most interviewees did not perceive artistic information visualizations to be necessarily untrustworthy, they voiced concerns about the lack of objectivity and scientific rigor in artistic visuals depicting climate change in general 12 .It is worth future efforts to identify the specific characteristics of artistic visualizations that can enhance their perceived credibility, such as the source 40 .
More importantly, as political partisans often engage in identity-protective attention and reasoning when viewing graphical evidence, it is critical to enhance or revamp conventional graphs with visual representations that elicit emotional and/or cognitive processes attenuating such tendency.Results of this study suggest that artistic representations of data, as compared to scientific data graphs, mitigate the political division in individuals' perceived relevance of climate change when the appraisal process involves self-reflection (i.e., writing about what they have seen and felt from the images).However, to further understand how and why prompted reflection upon art pieces may help bring politically divided citizens together on the issue of climate change, researchers should consider conducting mixed methods research that concordantly collects and analyzes quantitative and qualitative data.
As visual art has been increasingly used to convey climate change to a wide range of audiences in the U.S. and beyond, it should be executed in a way that not only engages people through esthetics, but also enables contemplation and introspection.Using artistic representations of data to merely attract attention or adorn informational texts may not fulfill art's full potential as a tool for public engagement.However, it should be noted that no artworks are created with unanimous goals in mind.A review of science-art programs in the U.S. revealed that although many of them aimed to inspire public action or activism, other programs attempted to foster interdisciplinary work between artists and scientists or enhance learning through creativity 16 .Future researchers should be aware of the diverse motivations behind the creation of artistic representations of scientific information and examine how they are processed in various cultural, educational, and communication contexts.The advent of advanced data visualization tools, AI-generated art, and increasing collaborations between scientists and artists will quickly expand the ways in which climate science can be creatively represented to the public.Examining how the combined use of science and art may influence unconcerned and uninterested audiences outside of traditional informal learning settings (e.g., on Instagram and TikTok) is worth prioritizing in future research.Nonetheless, the increasing popularity of social networks may assimilate what people have seen and felt by empowering ubiquitous liking and sharing of an infinite number of images on a day-to-day basis.With regards to climate change, online audiences are risk being "caught between image regimes" that are governed more by fear than by concerns "for the welfare of humans, planet or even the technological infrastructure of the system itself" 41 .
With these considerations in mind, we would caution against a "reductionism" approach to examining the interplay between climate science and (visual) art which exclusively focuses on portraying the imagined states of loss and problems associated with warming temperatures 42 .Instead, future researchers should use our findings as motivation to further explore how (1) alternative visual discourses infused with hope and (2) community participatory creation of art (e.g., through a collaboration between scientist-artists and target audiences) may be more effective in mitigating political polarization in the U.S. on the issue of climate change.

Methods
Sample.Forthright panelists were recruited through both online and offline channels, including digital networks and mail campaigns via address-based probability sampling methods.Participants (total N = 671) were asked if they had ever visited Instagram to view others' shared photos or videos before proceeding to offer consent to participate in the study.For both samples, nearly half (50.7%) of the participants self-identified as females, 74.4% of them were white, and the average age of the sample was 44 years old (s.d.17.03).The sample's educational profile generally reflected that of the general U.S. population-27.6% of participants reported the highest degree they received as a high school diploma/GED and another 22.6% of the sample had a bachelor's degree from a 4-year college.
Homogeneity of treatment group participants.Results from a series of analysis of variance (ANOVA) showed homogeneous distributions of demographics, including age, gender, educational attainment, race, and household income across the four treatment groups.Members of each group also reported no significant difference in their preexisting concern with climate change, science education, art education, political ideology, frequency of social media use, and interest in experiencing visual art via Instagram.
Art interest was measured by asking participants to indicate their agreement and disagreement with five statements on a seven-point scale (1 = "strongly disagree", 4 = "neither agree nor disagree", 7 = "strongly agree"), including "I like to talk about visual art with others"; "Many people that I know are interested in visual art"; "I'm interested in visual art"; "I am always looking for new works of visual art"; "During my everyday life, I spontaneously notice visual art" 19 .
To measure information recall, we asked five multiple-choice questions regarding the shown images and caption text.The answers were then recoded into correct as 1 and incorrect or not remembered as 0, and the sum of correct answers was used as the dependent variable.
(1) According to the post, which atmospheric gas was mentioned as influencing the climate?Perceived credibility of the mockup Instagram posts was measured by asking respondents to indicate agreement or disagreement on six statements using a seven-point scale (1 = strongly disagree, 7 = strongly agree), including the post "is trustworthy/is from a reputable source/is accurate/contains incorrect information (reversely coded)/is unbiased/is objective".The mean value was used as an index for viewers' perceived credibility of the post.
Perceived relevance of climate change was measured by asking respondents to indicate agreement or disagreement with three statements on a seven-point scale (1 = strongly disagree, 7 = strongly agree), including "This post seems relevant to my daily life"; "The post highlights the consequences of climate change that would affect me personally"; and "This post makes me think about my role in the current climate situation" 18 .
To measure political leaning, we standardized and combined party identification and political ideology.Party identification was measured on a sevenpoint scale (1 = strong Democrat, 4 = Independent, 7 = strong Republican).Political ideology was measured by the mean of two items asking respondents to report their ideology on economic and social issues respectively using a seven-point scale (1 = very liberal, 4 = moderate, 7 = very conservative).
In addition, to ensure the homogeneity of treatment group participants, we measured age, gender, education, race, preexisting concern with climate change, science education, art education, frequency of social media use, and interest in experiencing visual art via Instagram as these factors may possibly interfere with how respondents react to the stimuli.Specifically, age was measured by asking respondents to report the year when they were born.Respondents reported their gender, education, and race by selecting an option from the provided lists.
Preexisting concern with climate change was measured by asking respondents' agreement with three statements, including "Climate change is a current problem"; "Climate change is affecting the weather"; and "I am concerned about climate change" on a seven-point scale (1 = strongly agree, 4 = neither agree nor disagree, 7 = strongly disagree) (Cronbach's alpha = 0.94, mean 5.35, s.d.1.67).Science/art education was measured by asking if participants' college degree is in a scientific/art or science/art-related field as well as the number of college-level science/art courses ever taken.We also asked participants to report their frequency of visiting six popular social media sites, including Facebook, Twitter, TikTok, YouTube, Instagram, Snapchat on an eight-point scale, ranging from 0 (never) to 7 (multiple times a day).Last, participants reported their frequency of doing art-related activities on Instagram, including "view visual art", "comment or like visual art", and "post something related to visual art" on the same eight-point scale (Cronbach's alpha = 0.90, mean 3.7, s.d.2.4).
