Publication in West European Politics: New political parties through the voters’ eyes

Why do citizens at the ballot box prefer new political parties over established political parties?

Scholars mainly studied the formation of political parties on the macro-level. Because party establishment is by definition tied to electoral accomplishments, macro-level studies on successful party establishment explicitly, or implicitly, presuppose assumptions about the behaviour of individual citizens whose votes are necessary for electoral success. Against that backdrop, I argue that to explain the conditions of successful party establishment we need to understand the motivational underpinnings of voting for a new party on the individual level.

Using cross-national voter surveys and long-term panel data from Germany (2005-2013) and the Netherlands (1998-2002), the study contrasts the implicit assumptions about voter behaviour of two macro-level theories on party emergence: the equilibrium- and the protest-based approaches on party emergence. The empirical analysis shows that there are merits to both approaches, but in many cases, the individual-level assumptions of both models do not square with the observed voting behaviour.

Determinants of Voting for a New Political Party

Although proximity to a new party matters, the findings do not support the equilibrium perspective’s tenet that new parties gain votes from citizens whose views were not represented in the preceding election. Moreover, political discontent was found a fertile soil for new parties to gain electoral support, but the relationship between discontent and voting is more complex than theoretically suggested. These findings on individual voter behaviour may inform further theoretical work on the successful establishment of new political parties.

Interviews on Assessing and Improving the Credibility of Social Science Research

The MZES Open Social Science Conference 2019 is over. 80 participants from all world continents (except Oceania) have participated, discussing and practicing „New Standards in Research Transparency and Reproducibility“.

The entire conference was live-streamed, sparking vivid debates on twitter with several hundred tweets using the #ossc19 hashtag. If you have missed the conference, you can all watch all keynote speeches, presentations and discussions on YouTube.

Keynote lecture: Arthur Lupia | It’s Up to Us – Transparency and the Public Value of Science

After the conference, I gave two interviews to German Public radio on asseing and improving the credibility on social science research:

Talking about politics: When, with whom and to what effect?

When you talk to your spouse or friends, what do you talk about? Talk has political ramifications. According to moral psychologist Jonathan Haidt, human beings tend to disregard most information that contradict our pre-existing attitudes but social cues are the single influence with the potential to elicit a lasting change of mind.

However, although communication with friends and neighbours has the potential of transmitting new information and changing our minds, this potential will not materialize if we only converse with like-minded people. Considering ongoing debates about filter-bubbles and echo-chambers, this seems to be what is happening.

The Campaign Panel of the German Longitudinal Election Study allows shedding some light on the personal communication of ordinary citizens. In nine survey waves, respondents were repeatedly asked about the political conversations they have had in the past week: Whether they had any and with whom. Naturally, these measures are self-reported and therefore imperfect. Having these caveats in mind, here are some basic findings of research in collaboration with Lea Gärtner.

First, individuals differ strongly in whether and how often they talk about politics. Figure 1 shows the distribution of self-reported frequency of political conversations over the past week. Some people never touched upon this issue while a handful of people talked about politics every day.

Figure 1: Frequency of Political Conversations

We also investigated whether citizens only talk with like-minded people. In this case, „like-minded“ is operationalized as talking to a person who the respondent perceives as having the same vote intention. Specifically, we calculated the relative homogeneity of a person’s discussion network where „1“ denotes a respondent’s discussion network is not biased towards her own party. If the respondent intends to vote for CDU and the CDU polls at 30% then the discussion network is unbiased if it consists of 30% CDU voters. However, if 60% of the respondent’s conversation partners intend to vote CDU, then the respondent apparently prefers like-minded conversation partners and the coefficient would be „2“.

Figure 2: The Development of Homogeneity of Discussion Networks across the Election Campaign

Figure 2 provides three fundamental insights. First, citizens do prefer like-minded conversation partners. Regardless of party preference, the average citizen has twice as many conversation partners with identical vote preferences in her discussion network than we would have expected if discussion networks were unbiased. Second, the homogeneity of discussion networks does not increase when the election draws closer. Third, voters of AfD and (surprisingly?) voters of the Green Party have the strongest inclination to talk to like-minded people.

Finally, we should note that while we observe a bias towards congeniality, most of the respondents do not live in filter-bubbles. Although people prefer talking with like-minded others, other analyses show that most people also do talk to citizens with other points of view.

New publication in PVS: Why too many political science findings cannot be trusted and what we can do about it

For several months or years now I have been learning and thinking about the credibility of social scientific research. In the wake of this progress, I thoroughly revised my beliefs about the evidential value of published research findings. When I was conducting my master’s studies and was reading a scientific study published in a scientific journal by full-grown scientists, I believed and never questioned that was I was reading must be true. I knew that some studies were better than others and that scientists occasionally err. Still, when I heard that one of those full-grown scientists claimed that „most published research findings are false“ I was puzzled.

Years later I am being involved in organizing the MZES Open Social Science Conference 2019, which brings together scholars from around the globe to discuss research credibility and what we can do improve it. Now, I have penned a commentary on Open Science with a particular focus on political science. Rather than being fatalistic, the commentary hopes to be analytic and constructive. The article is a review of the existing meta-scientific literature on the credibility of quantitative findings in political science. At best, the paper will serve as a primer for those who are not yet versed in these discussions and it will contribute to the ongoing debates about research credibility.

The article is now published online at Springer PVS and will be published in print in the Issue 1/2019 of the German Political Science Quarterly.

Why Too Many Political Science Findings Cannot Be Trusted and What We Can Do About It: A Review of Meta-Scientific Research and a Call for Academic Reform

Open Science Talk in Zurich: Warum wir sozialwissenschaftlichen Forschungsbefunden oft nicht trauen können

The IKMZ (Institut für Kommunikationswissenschaft und Medienforschung) invited me for a talk on the credibility of social scientific research. The presentation sparked an engaged debate about the incentive structures in academia and about what we can do to better align individual researcher rationality with the collective good of reliable research.

Release of unique longitudinal survey data: Repeatedly questioned respondents of the Short-term Campaign Panel 2013 and 2017

For which party have citizens voted back in 2013 who cast their ballot for the AfD in 2017? Were these voters AfD-adherents all along or did they abstain at the previous election or were they even voters of leftist parties at the previous elections?

In survey research, there are two ways of finding out: First, you can ask citizens after the federal elections 2017 about their vote choice at the recent election and then you also ask them to remember their vote choice at the previous election. The problem is that human beings are bad at remembering things. Just as we forget where we put our keys (only 5 minutes ago!) we also forget who we voted for four years ago. We are very bad at remembering. Research by Ruth Dassonneville shows that only half of those voters who have actually switched party choices between elections do remember that they had switched.

Therefore, the better option is having asked those voters already in 2013 about their vote choices and then to ask them again right after the elections in 2017.  This requires tracing respondents for a long period of time which means a lot of survey administration (and comes with other caveats, such as panel attrition). However, in addition to the accurate recall, such longitudinal survey data provide so many other benefits. For each individual, you can trace how his or his opinions about Merkel and immigrants (and how the personality or individual sense of efficacy changed) over all these years.

Such a longitudinal dataset is now available for the German Federal Elections 2013 and 2017.

  • Respondents surveyed 18 times
  • before/after German federal elections 2013 & 2017
  • N=2,725
  • about 5,000 substantive variables
  • free, open and well documented (German only at the moment)

You can find the data here.

This dataset is provided by German Longitudinal Election Survey. Other GLES panel datasets include GLES 2017 Campaign Panel (web, N=20,000), Long-Term Panel surveys (based on probability facetoface sampling), RCS (2 waves, telephone).

MZES Open Social Science Conference: Call for Papers published

With my amazing colleagues Nate Breznau and Eike Mark Rinke, I have the pleasure to organize a conference on a topic that is of personal importance for me. It concerns the practices and politics of doing research and is about establishing new standards of reproducibility and transparency in social science research.

Here is our call for papers. Please forward it to friends and colleagues and consider participating. Feel free to contact me with any questions you might have.

CfP — MZES Open Social Science Conference 2019: Practicing New Standards in Transparency and Reproducibility

This conference is a forum for practicing and discussing credibility, transparency and replicability in the social sciences.

About a decade ago, John Ioannidis claimed that “most published research findings are false”. While seeming outrageous at the time, a growing body of meta-scientific research in the behavioral and social sciences substantiated this claim, causing uncertainty about the trustworthiness of published scientific findings. We believe that threats to the validity of published findings in the social sciences are widespread and systemic. Therefore, this conference promotes introspection about the current state of social science research and exchange on the opportunities for institutional and methodological improvement in the future.

The conference is supported by the Berkeley Initiative for Transparency in the Social Sciences (BITSS) and will take place from 25-27 January 2019 in Mannheim, Germany.

Article at LSE Business Review: For free trade, but against TTIP: public opinion and the backlash against globalisation

LSE Business Review has published an article of ours (Jungherr, Mader, Schoen, Wuttke) summarizing the paper „Context-driven attitude formation: the difference between supporting free trade in the abstract and supporting specific trade agreements“, published in Review of International Political Economy. 

Considering current discussions about the eminent trade war between the US and Europe and related discussions about „TTIP light“, we hope this piece has some value for explaining public support and opposition towards free trade and specific free trade agreements:

Why some people care about politics and others hardly bother at blog – Blog Post at International Society of Political Psychology

Theory in a nutshell

Why some people value political engagement and even find pleasure in engaging with politics while others hardly bother about the political domain, is a crucial question for the functioning of democratic societies. In my dissertation, I investigate what we can learn from motivation studies (largely neglected by political scientists) to understand the roots of political engagement. My contribution is to investigate the nonpolitical origins of political engagement in early childhood experiences, more specifically, the level of need satisfaction provided in the parental home during socialization’s formative phase.

I had the opportunity to write about these thoughts and the findings from two analyses of longitudinal cohort data at the ISSP blog. Please feel free to provide any comments and criticism.
