Computer simulations reveal partisan gerrymandering 

Post developed by Katherine Pearson 

How much does partisanship explain how legislative districts are drawn? Legislators commonly agree on neutral criteria for drawing district lines, but the extent to which partisan considerations overshadow these neutral criteria is often the subject of intense controversy.

Jowei Chen developed a new way to analyze legislative districts and determine whether they have been unfairly gerrymandered for partisan reasons. Chen, an Associate Professor of Political Science and a Research Associate at the Center for Political Studies, used computer simulations to produce thousands of non-partisan districting plans that follow traditional districting criteria. 

Simulated NC map

These simulated district maps formed the basis of Chen’s recent expert court testimony in Common Cause v. Lewis, a case in which plaintiffs argued that North Carolina state legislative district maps drawn in 2017 were unconstitutionally gerrymandered. By comparing the non-partisan simulated maps to the existing districts, Chen was able to show that the 2017 districts “cannot be explained by North Carolina’s political geography.” 

The simulated maps ignored all partisan and racial considerations. North Carolina’s General Assembly adopted several traditional districting criteria for drawing districts, and Chen’s simulations followed only these neutral criteria, including: equalizing population, maximizing geographic compactness, and preserving political subdivisions such as county, municipal, and precinct boundaries. By holding constant all of these traditional redistricting criteria, Chen determined that the 2017 district maps could not be explained by factors other than the intentional pursuit of partisan advantage. 

Specifically, when compared to the simulated maps, Chen found that the 2017 districts split far more precincts and municipalities than was reasonably necessary, and were significantly less geographically compact than the simulations. 

By disregarding these traditional standards, the 2017 House Plan was able to create 78 Republican-leaning districts out of 120 total; the Senate Plan created 32 Republican-leaning districts out of 50. 

Using data from 10 recent elections in North Carolina, Chen compared the partisan leanings of the simulated districts to the actual ones. Every one of the simulated maps based on traditional criteria created fewer Republican-leaning districts. In fact, the 2017 House and Senate plans were extreme statistical outliers, demonstrating that partisanship predominated over the traditional criteria in those plans. 

The judges agreed with Chen’s analysis that the 2017 maps displayed Republican bias, compared to the maps he generated by computer that left out partisan and racial considerations. On September 3, 2019, the state court struck down the maps as unconstitutional and enjoined their use in future elections. 

The North Carolina General Assembly rushed to adopt new district maps by the court’s deadline of September 19, 2019. To simplify the process, legislators agreed to use Chen’s computer-simulated maps as a starting point for the new districts. The legislature even selected randomly from among Chen’s simulated maps in an effort to avoid possible accusations of political bias in its new redistricting process.

Determining whether legislative maps are fair will be an ongoing process involving courts and voters across different states. But in recent years, the simulation techniques developed by Chen have been repeatedly cited and relied upon by state and federal courts in Pennsylvania, Michigan, and elsewhere as a more scientific method for measuring how much districting maps are gerrymandered for partisan gain. 

Rousing the Sleeping Giant? Emotions and Latino Mobilization in an Anti-Immigration Era

Post developed by Nicholas Valentino, Ali Valenzuela, Omar Wasow, and Katherine Pearson 

ICYMI (In Case You Missed It), the following work was presented at the 2019 Annual Meeting of the American Political Science Association (APSA).  The presentation, titled “Rousing the Sleeping Giant? Emotions and Latino Mobilization in an Anti-Immigration Era” was a part of the session “The Rhetoric of Race” on Friday, August 30, 2019.

Since the 2016 presidential campaign anti-immigration policies have been very popular among President Trump’s strongest supporters, though they do not present obvious benefits to the economy or national security. Strategists suppose that the intent of the anti-immigration rhetoric and policies is to energize the president’s base. 

But what about people who identify with the targets of these policies, specifically Latinos? Are they mobilized against anti-immigration proposals, or are they further deterred from political participation? 

New research by Nicholas A. Valentino, Ali Valenzuela, and Omar Wasow finds that anger was associated with higher voter turnout among Latinos, but the Latinos who expressed more fear had lower voting rates.

voting rates by race and emotion

The role of emotions in politics is complex. The research team begins with the observation that negative emotions do not always have negative consequences for politics. Indeed, negative emotions may promote attention and interest, and drive people to vote. They draw a distinction between different negative emotions: while anger may spur political action, fear can suppress it. 

The research team fielded a nationally-representative panel survey of white and Latino registered voters before and after the 2018 midterm elections. Respondents were asked about their experience with Immigration and Customs Enforcement (ICE) officials and their exposure to campaign ads focused on immigration. Participants were also asked to rate their emotional reactions to the current direction of the country. 

The results showed that Latinos interacted with ICE more frequently than whites did, but both groups had the same level of exposure to campaign ads. Latinos reported more anger than whites, and also more fear. In fact, among the negative emotions in the survey, fear among Latinos was highest.  

In the sample the validated voting rate among Latinos was 39%; among whites in the sample it was 72%, demonstrating the under-mobilization of Latino voters. Whether Latinos vote in greater numbers in 2020 may depend on whether they are mobilized by anger against anti-immigration rhetoric, or whether they are deterred by fear stemming from policies like ICE detention and deportation. 

Toward a Typology of Populists

Post developed by Pauline Jones, Anil Menon, and Katherine Pearson 

ICYMI (In Case You Missed It), the following work was presented at the 2019 Annual Meeting of the American Political Science Association (APSA).  The presentation, titled “Putin’s Pivot to Populism” was a part of the session “Russia and Populism” on Sunday, September 1, 2019. 

The rise in populism around the world has received much attention, but not all populists are the same. In a new paper, Pauline Jones and Anil Menon present an original typology of populists that goes beyond typical left-wing versus right-wing classifications. 

To better understand the different types of populists and how they operate, Jones and Menon examine two key dimensions: position within the political landscape (outsider versus insider), and level of ideological commitment (true believer versus opportunist). 

Populists tend to frame their criticism of political elites differently depending on whether they are political outsiders or government insiders. While outsiders are free to criticize those in power broadly, populists who hold political power are more likely to tailor their criticisms to their political opponents. Insiders are also more careful not to attack members of the elite with whom they will need to build political coalitions. 

Many populists evoke the past, but outsiders and insiders tend to do so differently. Whereas outsiders focus on the near past as a critique of a corrupt elite, political insiders instead focus on the distant past to evoke better days of shared national values. 

Jones and Menon also draw distinctions between true believers in populism and those who embrace populism for purely strategic reasons. True believers will remain strongly committed to enacting their populist agenda once in office; opportunists will use populist rhetoric to gain power, but won’t support their platform strongly if elected.  

The intersection of these two dimensions leads to the classification of populists into four types, illustrated in the table below: Oppositional, Classical, Strategic, and Pivot. 

Classification of populists

The most common variety of populist is the oppositional populist, who are outsiders and true believers. Oppositional populists put their agenda before all else and distance themselves from the mainstream elite. 

Classical populists sometimes start out as outsiders who become insiders once they are elected to office. Like oppositional populists, they are strongly committed to enacting their agenda; unlike oppositional populists, classical populists can enact their agenda from a position of power. Because they are insiders, classical populists are more selective about criticizing elites. 

Pivot populists are a rare group of political insiders who adopt populist rhetoric with little or no commitment to the populist ideology. Jones and Menon point to Russia’s Vladimir Putin as an example of a pivot populist who has adopted populism to bolster support for his regime while deflecting blame for the country’s problems. 

The final category is strategic populists. Like Donald Trump in the United States, strategic populists are outsiders with a weak commitment to the populist agenda. Strategic populists are broadly anti-elite, and also use their rhetoric to create divisions among the people. Once in power, they are unlikely to alienate elites by pursuing populist policy goals. 

Using Text and Images to Examine 2016 Election Tweets

Post developed by Dory Knight-Ingram 

ICYMI (In Case You Missed It), the following work was presented at the 2019 Annual Meeting of the American Political Science Association (APSA).  The presentation, titled “Using Neural Networks to Classify Based on Combined  Text and Image Content: An Application to Election Incident Observation” was a part of the session “Deep Learning in Political Science” on Friday, August 30, 2019.

A new election forensics process developed by Walter Mebane and Alejandro Pineda uses machine-learning to examine not just text, but images, too, for Twitter posts that are considered reports of “incidents” from the 2016 US Presidential Election. 

Mebane and Pineda show how to combine text and images into a single supervised learner for prediction in US politics using a multi-layer perceptron. The paper notes that in election forensics, polls are useful, but social media data may offer more extensive and granular coverage. 

The research team gathered individual observation data from Twitter in the months leading up to the 2016 US Presidential Election. Between Oct. 1-Nov. 8, 2016, the team used Twitter APIs to collect millions of tweets, arriving at more than 315,180 tweets that apparently reported one or more election “incidents” – an individual’s report of their personal experience with some aspect of the election process. 

At first, the research team used only text associated with tweets. But the researchers note that sometimes, images in a tweet are informative, while the text is not. It’s possible for the text alone to not make a tweet a report of an election incident, while the image may indeed show an incident. 

To solve this problem, the research team implemented some “deep neural network classifier methods that use both text and images associated with tweets. The network is constructed such that its text-focused parts learn from the image inputs, and its image-focused parts learn from the text inputs. Using such a dual-mode classifier ought to improve performance. In principle our architecture should improve performance classifying tweets that do not include images as well as tweets that do,” they wrote.

“Automating analysis for digital content proves difficult because the form of data takes so many different shapes. This paper offers a solution: a method for the automated classification of multi-modal content.” The research team’s model “takes image and text as input and outputs a single classification decision for each tweet – two inputs, one output.” 

The paper describes in detail how the research team processed and analyzed tweet-images, which included loading image files in batches, restricting image types to .jpeg or .png., and using small image sizes for better data processing results. 

The results were mixed.

The researchers trained two models using a sample of 1,278 tweets. One model combined text and images, the other focused only on text. In the text-only model, accuracy steadily increases until it achieves top accuracy at 99%. “Such high performance is testimony to the power of transfer learning,” the authors wrote. 

However, the team was surprised that including the images substantially worsened performance. “Our proof-of-concept combined classifier works. But the model structure and hyperparameter details need to be adjusted to enhance performance. And it’s time to mobilize hardware superior to what we’ve used for this paper. New issues will arise as we do that.” 

The Politicization of Policies to Address Climate Change

Post developed by Erin Cikanek, Nicholas Valentino, and Katherine Pearson 

ICYMI (In Case You Missed It), the following work was presented at the 2019 Annual Meeting of the American Political Science Association (APSA).  The presentation, titled “The Politicization of Policies to Address Climate Change” was a part of the session “The Dynamics of Climate Policy Support in the US” on Friday, August 30, 2019.

Climate change is a truly polarizing issue. Partisans on either side of the issue have such deeply entrenched beliefs that there is little that can change minds. But this wasn’t always the case. For example, in 1988 Democrats and Republicans were in close agreement about the amount of money the government should spend on environmental protection. More recently, partisans have become more polarized in their level of concern about climate change. 

How do scientific policy issues become so polarized, and how quickly does this happen? New research by Nicholas Valentino and Erin Cikanek measures public awareness of Carbon Dioxide Removal (CDR) polices, and explores whether attitudes toward these policies are as politicized as climate change overall. 

Valentino and Cikanek conducted two studies to examine political polarization of CDR. First, they surveyed a large, nationally representative sample of people to measure how much they knew about climate change. The questions covered a broad set of issues and strategies for dealing with the problem. This survey revealed that the public has a high level of knowledge about climate change. 

The study also demonstrates that partisanship is highly predictive of knowledge about climate change. Democrats responded with significantly more accuracy than Republicans did. When respondents were asked specifically about technologies to remove carbon dioxide from the atmosphere, overall knowledge was lower, but Democrats and Republicans answered questions with the same level of accuracy, as shown in the figure below.  Valentino and Cikanek note that “this pattern is consistent with the possibility that elite rhetoric has come to suppress accuracy on general climate change knowledge among Republicans, but this has not yet occurred for knowledge in this newer domain (CDR).” 

climate change

The second study experimentally tested whether CDR policies are sensitive to partisan cues. CDR policies have not been debated as much or as publicly as climate change in general. Are these policies as susceptible to political polarization?  

Survey respondents were randomly assigned to one of three groups. A control group was asked about current climate change policies, as well as carbon reduction policies. The first treatment group received information that applied partisan stereotypes to the CDR policies: Republican hesitation about CDR because it might hinder business, and Democratic encouragement to save the environment. The second treatment group received information that ran counter to those stereotypes: Republican support for a pro-business solution to climate change, and Democratic concern that the solution may encourage businesses to pollute. 

The partisan cues had very little effect on the response to CDR policies. Interestingly, the counter-intuitive partisan cues backfired: when Republican respondents read the treatment showing Republican support for CDR, they opposed it slightly more. The very weak effect of partisan cues on support for CDR may show that CDR policies may be more resistant to polarization. 

The more politicians discuss scientific policy issues, the more polarized the discussion tends to become. However, Valentino and Cikanek see reason to hope that compromises remain possible for issues like carbon removal, which have not yet been subjected to partisan rhetoric. 

Whites’ Responses to Police Violence Depend on the Race of the Victim

Post developed by Nicole Yadon, Kiela Crabtree, and Katherine Pearson

ICYMI (In Case You Missed It), the following work was presented at the 2019 Annual Meeting of the American Political Science Association (APSA).  The presentation, titled “Breeding Contempt: Whites’ Reactions to Police Violence against Men & Dogs” was a part of the session “Race and Politics: New Theoretical and Methodical Insights v. Old Paradigms” on Thursday, August 29, 2019.

Of 987 individuals killed by police officers’ use of fatal force in 2018, 209 were black, and, of those, 200 were black men. The targeting and killing of unarmed black men has become a point of interest for news cycles and social movement organizations alike and is indicative of a fraught relationship between communities of color and police. With increasing press coverage over the past decade, academics have also begun to focus on the intertwining relationship between police use of force and race, complementing a long-standing literature which links blacks to perceptions of criminality, violence, and hostility. One area that is not well-developed, however, is how news coverage of police shootings influences attitudes towards police and policies related to policing for white Americans.

Building from research on race, media coverage, and policing, new research by Nicole Yadon and Kiela Crabtree examines reactions to police and policing by white people after they read about a police officer shooting a white man, a black man, or a dog. They find that news reports about police shootings change attitudes about police, but the strength of the reaction varies depending on who the victim is. 

Specifically, Yadon and Crabtree’s study examines white individuals’ feelings towards police following exposure to news of a fatal police shooting. They designed a survey that presents participants with a fictional but realistic news report about a fatal police shooting. In one version the shooting victim is a black man, another reports that the victim is a white man, and in the third version the victim is a dog. Key information about the shooting remains the same across all three versions. A control story, unrelated to race or police shootings, was given to a control group for purposes of comparison with the three treatment groups. This experiment was conducted via Amazon’s Mechanical Turk (MTurk) platform, with 802 white participants. After reading one of the news reports, participants were asked a series of questions about their perceptions of the events in the article and about their attitudes towards police more broadly.

When asked whether they agree or disagree that police officers rarely abuse their power, the control group who had not read about a police shooting had a neutral response — about 0.49 on the 0 to 1 scale. Respondents who read about a white man or a dog being shot by police had a markedly different reaction. Participants who read an article about a white man shot by police had a 7 percentage point decrease in belief that police rarely abuse their power while those who read about a dog shot by a police officer had an 8 percentage point decrease. This is equivalent to survey respondents moving from feeling neutral about whether police abuse their power to a slight disagreement that abuse of power is rare after reading about either a White victim or dog victim. 

Importantly, when white survey participants read about a black victim of a police shooting, it did not change their perception of abuse of power by police officers. Put differently, those who read about a black victim held views abuse police abuse of power that were indistinguishable from those who read the control story. The evidence suggests, then, that white respondents react more strongly to a police shooting if the victim is a dog than a black man. 

Belief that police rarely abuse power

 

A separate set of questions focused on interest in varying forms of political participation following exposure to the news story. Do white people feel moved toward political participation in response to a story about a police shooting? First, the survey asked whether respondents would support a civilian review board to oversee the police department in their community. Those who read about a police officer shooting a black man or a dog were no more likely to support a civilian review board than the control group. However, those who read about the shooting of a white man were more than 7 percentage points likely to support civilian review in their community.

Support for local civilian review board

A second question asked about interest in signing a petition urging Congress to take action towards reducing excessive use of force by police. In contrast to the civilian review board question, levels of support for signing a petition were very low across all groups. In fact, white participants do not appear increasingly motivated to urge Congress to take action against excessive police force regardless of the victim’s identity.

Taken together, Yadon and Crabtree’s results suggest that exposure to a news story about a police shooting draws strong reactions from white people. Of concern, however, is that such reactions are largely limited to viewing either a white man or a dog victim. Indeed, across most of the items which measure attitudes towards police, there are no statistically significant differences when comparing the control condition with the black victim treatment. Such connections are increasingly important to study as cities move toward tightening oversight of police forces and many such initiatives are presented to citizens at the ballot box. Thus, the attitudes citizens hold about police are not only their own. The public’s opinion has potentially lasting effects for the future of policing in local communities.

‘13 Reasons Why’ and Young Adults’ Risk of Suicide

By Michael Rozansky. Original post for the Annenberg Public Policy Center.  

One of the most heavily watched and debated fictional portrayals of suicide in recent years was the Netflix series “13 Reasons Why,” which raised outcries about potential contagion stemming from its portrayal of a female high-school student’s suicide.

Google searches about suicide spiked after the release of Season 1, physicians said that several children created lists of “13 reasons why” they wanted to kill themselves, and one hospital saw an increase in admissions of children who exhibited suicidal behavior. But two studies conducted after the series was released found some beneficial effects.

Given the series’ popularity and its potentially harmful effects, researchers at the University of Vienna, the University of Leuven, the University of Michigan, and the Annenberg Public Policy Center (APPC) conducted a study to more fully understand the effects of the show through a survey of U.S. young adults, ages 18 to 29, before and after the May 2018 release of its second season.

In the study, published today in the journal Social Science & Medicine, researchers found that:

  • Viewers who stopped watching the second season partway through reported greater risk for future suicide and less optimism about the future than those who watched the entire season or didn’t watch it at all;
  • Students – who were nearly 60 percent of the sample – were at an overall higher risk for suicide. Of the viewers who dropped out of watching the series midway, students were at a significantly higher suicide risk than non-students (see Figure 1);
  • The show appeared to have a beneficial effect on students who saw the full second season: They were less likely to report recent self-harm and thoughts of ending their lives than comparable students who didn’t watch the series at all. And viewers in general were more likely to express interest in helping a suicidal person, especially compared with those who stopped watching;
  • Netflix’s warning about the show’s potentially disturbing content that preceded Season 2 mainly appeared to increase viewing but did not appear to prevent vulnerable viewers from watching the season.

“Although there’s some good news about the effects of ‘13 Reasons Why,’ our findings confirm concerns about the show’s potential for adverse effects on vulnerable viewers,” said Dan Romer, APPC’s research director and the study’s senior author. “It would have been helpful had the producers done more to enable vulnerable viewers to watch the entire second season, which is when the show had its more beneficial effects.”

Fig. 1: Predicted suicide risk

Background on the study

Suicide is the second-leading cause of death among 15- to 29-year-olds. Media portrayals of suicide have been shown to have helpful and harmful effects. Stories of suicide in news and fictional media can elicit suicide – especially when they explicitly show suicide methods – in a phenomenon called the Werther effect, after Goethe’s novel “The Sorrows of Young Werther.” By contrast, news stories about people who have overcome a suicidal crisis have had a positive impact, a more recently documented phenomenon that is known as the Papageno effect, after the character in Mozart’s opera “The Magic Flute.”

For this study the researchers surveyed 18- to 29-year-olds, who reported having access to Netflix, both shortly before the second season was launched and a month later. A total of 729 respondents completed both the initial internet survey and the follow-up, which used validated scales to measure future suicide risk, hopelessness, recent self-harm, and related outcomes. Women were over represented in this sample (82 percent), perhaps because “13 Reasons Why” involved a female protagonist.

An indicator of distress

“13 Reasons Why” seemed to be particularly upsetting for young people who were already at a higher risk of suicide and who empathized with the main character, 17-year-old Hannah, who is bullied and sexually assaulted before deciding to end her life. As the researchers wrote, “We hypothesized that watching only some of the series could be an indicator of distress that led those viewers to discontinue exposure to the upsetting content.” The results appeared to support that idea, in that those who watched only some of the second season showed elevated risk of future suicide, an outcome that was stronger for current students.

At the same time, students who watched the entire second season reported less self-harm after watching than those who did not watch at all. Thus the findings suggest that over the course of a month following the second season, the show exerted a beneficial effect on some students.

The researchers added: “One explanation for the beneficial finding is that those at higher risk who persisted to the end were able to empathize with the challenges faced by the main characters and to take away a life-affirming lesson applied to their own lives.” The second season may have conveyed this message with more effectiveness than the first season, which mainly focused on the harm that the suicide inflicted on the victim’s friends and family.

“Given that we know that the Werther effect is a real phenomenon with detrimental consequences, the public outcry about potential contagious effects as a response to the first season is justified,” said the study’s lead author, Florian Arendt of the University of Vienna, Austria. “However, the second season appeared to have more content that could engender a beneficial effect than the first season, and this may have helped those who watched it in its entirety to walk away with more beneficial outcomes.”

Viewers who watched the full second season were also more likely to be sympathetic to a hypothetical friend who appeared to be suicidal. Here again the findings suggest that the show may have succeeded in creating empathy for those in a suicidal crisis.

Evidence the show “can harm some… and may actually help others”

In an accompanying commentary on the study in Social Science & Medicine, Anna S. Mueller of the University of Chicago’s Department of Sociology and Comparative Human Development said the findings “offer the strongest evidence to date that 13RW can harm some youth and the results demonstrate that it may actually help others, which is rarely considered in the media and suicide literature.”

Mueller, who was not connected with the study, said, “It also has important implications for what scholars should do next.” That includes “unpacking how exposure to suicide – whether through media or a personal relationship – transforms an individual’s vulnerability to suicide.”

What should Netflix do?

Romer said, “Producers of shows such as ‘13 Reasons Why’ need to be aware of the potential effects of their shows, particularly on vulnerable audiences. One way to do this would be to make the series less aversive to people who are sensitive to a story about suicide, because they may not get to the parts of the story that have more uplifting effects.”

The researchers noted that the study had limitations, including the one-month time frame for the observed effects. Also, it did not assess respondents’ experiences surrounding sexual assault, an important element in the series in both seasons, which could have influenced reactions.

Romer and Arendt’s co-authors are Patrick E. Jamieson, director of the Annenberg Health and Risk Communication Institute at the Annenberg Public Policy Center; Sebastian Scherr, of the School for Mass Communication Research, University of Leuven, Belgium; and Josh Pasek, of the Department of Communication Studies and Center for Political Studies, Institute for Social Research, University of Michigan.

Winners and Losers:
 The Psychology of Attitudes Toward 
Foreign Trade

Post developed by Katherine Pearson and Diana Mutz

Foreign trade is a complex issue, but the public still has strong opinions about the issue. Diana Mutz demonstrated that social psychology can help to understand attitudes about trade when she delivered the 2019 Miller Converse lecture. A recording of her talk “Winners and Losers: The Psychology of Attitudes Toward Foreign Trade” is available below.

Most people rely on small-scale social experiences to understand large-scale interactions such as international trade. From this understanding, people tend to embrace beliefs about trade that are not necessarily accurate. For example, folk beliefs suggest that impersonal transactions are more dangerous than personal ones, that trade is zero-sum, and that trade “deficits” mean that a country is losing more jobs as a result of imports than it gains due to exports. These beliefs are inaccurate, yet understandable, generalizations from the world of face-to-face social exchange.

Contrary to popular wisdom, trade preferences do not reflect people’s economic self-interest. Mutz demonstrates that, surprisingly, these attitudes are not influenced by a person’s occupation, industry of employment, community job loss, geographic location, or individual job loss. Instead, perceptions of what is in the collective economic interest determine attitudes toward trade. Coverage of trade in the media has a large influence on these perceptions. Media coverage of foreign trade was mostly negative until 2016. As media coverage of trade has become more balanced since 2016, support for trade has also increased.

Politicians from all parties have been unwilling to champion trade when running for office because foreign trade is seen as a political liability in the United States. As the world economy changes, Mutz asserts that leaders will need to advocate for trade and for safeguards against its negative effects. She cautions that it’s unhelpful to leave the public out of that conversation altogether as has been common in the past.

For an additional perspective, Mutz compares attitudes about trade in the United States and Canada. She finds that attitudes about trade in the two countries are different due to differing attitudes toward competition. Americans value competition more, and believe in the fairness of unequal outcomes. In the U.S., nationalism reduces support for foreign trade, but in Canada the opposite is true. Canadians who hold the strongest beliefs about national superiority want to promote more trade and immigration.

Differing perspectives on trade in these countries can be explained by variation in two different types of ingroup favoritism. First, Americans in Mutz’s studies systematically preferred trade agreements in which their fellow Americans benefited more than trading partners. In fact, there was no level of job benefits to foreign countries that would justify the loss of even a single American job. This was not the case among Canadians. In addition, Americans demonstrated their competitive attitudes toward trade by demonstrating greater support for trade agreements that not only benefit their country but also disadvantage the trading partner. Canadians, in contrast, preferred the kind of “win-win” trade agreement that economists suggest benefits all countries involved.

Attitudes about race drive attitudes about trade and Mutz finds that the reverse may also be true. In a study that asked respondents to select which students should be admitted to college, participants who had just watched an ad against foreign trade were less supportive of admitting Asian-American students, as well as students from Asia.

Mutz concludes that, while many of these results are distressing, attitudes remain malleable. Efforts to change opinions toward trade that emphasize similarity and shared values are more effective than efforts emphasizing pocketbook gains. Since 2016, her data shows that there has been an increase in support for foreign trade and a realization that it comes with benefits as well as negative consequences.

Portrait of a birther: White conservatives with political knowledge more likely to believe Obama conspiracy

Post developed by Morgan Sherburne for Michigan News.

White conservatives who not only have racial animus but are also knowledgeable about politics were the most likely group to believe that former President Barack Obama was not born in the United States, according to a University of Michigan Institute for Social Research study.

Michael Traugott and Ashley Jardina

The study, published in the Journal of Race, Ethnicity and Politics, teased out motivations of white voters for believing the so-called birther rumor. It found that white conservatives who ranked as having a high amount of knowledge were most likely to support the idea that Obama was not born in the U.S.

“This is a piece of social science research about biased perceptions in the political world and what their consequences might be,” said the study’s co-author Michael Traugott, a researcher at the Center for Political Studies at ISR. “It’s relevant because the whole concept of fake news is about devaluing information that doesn’t conform to either what you believe or what you want other people to believe, therefore suggesting a basis upon which it can be discounted or thrown away.”

Traugott and co-author Ashley Jardina, a former U-M doctoral student and now an assistant professor of political science at Duke University, say politically knowledgeable conservatives may be more likely to believe the rumor because they may follow what’s called a “motivated reasoning model.”

“One of the most interesting things about the motivated reasoning model is that the more resources the person has—which could be political information—the better they are able to argue against new information that doesn’t fit their worldview,” said Traugott.

Traugott and Jardina explored a portrait of a birther among white Americans using data from the 2012 American National Election Study. The ANES, conducted in person among a nationally representative sample of respondents, asked several questions assessing belief in contemporary conspiracy theories.

As recently as 2017, nearly a third of U.S. adults believed it was possible Obama was born outside the U.S., according to the researchers.

The survey also assessed participants’ knowledge by asking them to identify the office held by several political figures. A respondent’s score on the scale was the proportion of correctly answered questions.

The researchers found that 62 percent of very strong Republicans reported that Obama was born in the U.S. compared to 89 percent of very strong Democrats. Thirty-eight percent of very strong Republicans reported that Obama was probably born in another country, while 11 percent of very strong Democrats reported the same.

To estimate the impact of racial attitudes on the birther rumor, the researchers compared two conspiracy theories detailed in the 2012 ANES survey: the Obama birther rumor and the existence of the Affordable Care Act “death panels,” or, the idea that the ACA authorized government panels to make end-of-life decisions for people on Medicare.

Additionally, the researchers found:

  • Strong Republicans with higher levels of racial animus are more inclined to believe the birther rumor, but not the death panel rumor.
  • Republicans both low on resentment and low on knowledge are also more inclined to believe the birther rumor.
  • Democrats with higher levels of racial resentment are not significantly inclined to adopt either rumor.
  • Democrats low on knowledge and high on resentment are more likely to adopt birther beliefs.
  • High-knowledge Democrats with high levels of racial resentment are less likely to believe the rumor.

“Until recently, the relationship of party identification to things like voting behavior had weakened, but it has strengthened again,” Traugott said. “We expected partisanship would play a role in attitudes about Barack Obama, and because he was an African American, racial attitudes would play a role as well. These things are now increasingly important because of this kind of tribalism that’s infecting contemporary politics.”

What happened in the 2018 Midterm Elections?

Elections experts Ken Goldstein, Walter Mebane, and Vincent Hutchings analyzed the results and key lessons of the 2018 Midterm Elections at a round table discussion hosted by the Center for Political Studies on November 13, 2018. A recording of the event is available below.

Ken Goldstein began his presentation by noting that there are still races that do not have a clear winner a week after the election, including the Senate and Governor’s races in Florida and the Governor’s race in Georgia.

Leading up to the Midterm Elections, some observers anticipated big wins for the Democratic Party. Goldstein observed that while there was a general lack of exuberance on the part of Democrats on election night, further reflection reveals that there were meaningful shifts in this election. Although the “blue wave” of Democratic wins didn’t materialize, the number of congressional seats changing away from the President’s party was of similar magnitude to past midterm elections.

Goldstein drew attention to the behavior of independent voters. Exit poll data show that independents favored Republican candidates for the House of Representatives in the past two midterm elections, as well as the 2016 General Election. In contrast, independent voters were more likely to vote for Democratic House candidates in 2018 by a margin of 12 percentage points.

Were the polls leading up to the election predictive of the actual outcome? Goldstein said they were fairly accurate, but reminded the audience that many congressional seats were not in play in this election. There are few high-quality state-level polls, which makes forecasting less accurate. More probability-based surveys that weight responses for education and race of the respondent would improve the accuracy of predictions.

Looking at the big picture trends, Goldstein observed that there was a substantial increase in the number of women running for office and winning, as well as large increases in non-white voters. He shared a map showing what the results of the presidential election would look if votes followed the same partisan break-down as the 2018 midterms. However, Goldstein cautioned that presidential campaigns are very different from congressional campaigns, and that a presidential candidate running a nation-wide campaign will face challenges in changing districts, especially in the Midwest.

Next, Walter Mebane presented analyses he has conducted using election forensics. Mebane coined the term “election forensics” to describe a set of statistical methods he developed to determine whether the results of an election accurately reflect the intentions of the electors.

Using Twitter data from the 2016 General Election Mebane analyzed reports of election incidents, including wait times and problems with voting. During the 2016 General Election people used Twitter to report different kinds of election incidents depending on their partisan affiliation. These incidents tended to be reported in replies to people with similar partisan affiliations.

Mebane discovered that there are partisan differences in the types of incidents that Twitter users shared during the 2016 General Election. For example, Republicans were less likely to report a long line to vote, but more likely to report registration problems. A significant conclusion from this finding is that such observational biases and communication silos suggest partisans tended to form different impressions of how the 2016 election went, supported by the divergent reported experiences. These patterns will probably continue in 2018, according to Mebane.

Vincent Hutchings, Professor of Political Science at the University of Michigan

Vincent Hutchings analyzed the shifting demographics of the American electorate. Hutchings presented data showing that Democratic voters have become more racially diverse in the past 20 years, while Republican voters have remained predominately white. Similarly, the Congress elected in 2018 is the most diverse in the history of the United States, but the increase in diversity has been primarily among Democrats elected to Congress.

Reviewing voting data by race, gender, age, marital status, and education, Hutchings notes that each demographic group voted for Democrats at a higher rate than they did in the 2014 Midterm Elections. However, the magnitude of change was different for each group.

Some elections experts wondered whether women would vote for Democrats at higher rates in 2018 in response to the #MeToo movement, the contentious confirmation of Justice Kavanaugh, and controversial remarks about women made by President Trump. Hutchings showed that, among white voters, men and women both shifted toward Democratic candidates, but the gender gap didn’t change. Married men and married women both moved toward the Democratic Party House candidates at roughly equal rates in 2018 compared to 2014. No matter how Hutchings examined gender, he found no evidence that white women behaved differently than comparable men, relative to their preferences four years ago.

Votes by gender and marital status

Similarly, Hutchings observed meaningful trends related to generation and education. Voters under 30 years old voted for Democrats at a higher rate than voters under 30 in 2014. Democrats also increased gains among college-educated white voters compared to the 2014 Midterm Elections. Hutchings concluded that, while media may focus on gender differences between Democratic and Republican voters, more important differences are emerging along generational and educational lines, and these are trends to watch
