A necessary condition for democracy to function properly is that citizens make informed electoral decisions. If voters are to respond to a party’s policy performance, knowledge of (and an understanding about) the parties’ policy positions is of primary importance. In particular, information plays a crucial role for both voters and parties in spatial voting models in which to secure, increase or even maximize their vote shares, parties are keen to take up favourable policy positions on whatever dimension is relevant in the specific election. At the same time, voters’ identification of the party yielding the highest utility regarding their vote choice depends on knowledge about parties’ positions.Footnote 1
There is a degree of uncertainty in each election, as voters will not know precisely the effect that a vote for a particular party or candidate will have on their welfare. Greater awareness of the positions of parties will, however, reduce uncertainty about the consequences of electing a particular party.Footnote 2 Hence, information has a twofold effect on voters. First, a voter’s own position is better informed and is more likely to be consistent with other issue orientations. Secondly, voters are better able to identify party positions correctly – the information effect we focus on in this article – and vote more consistently with their own preferences.
In models of vote choice, the information chain between parties and voters has mostly been analysed directly: parties offer information on their policy positions to the electorate, and based on this information a voter will then choose the party that is most proximate to her position (proximity) or the one on her side of the status quo (directional).Footnote 3 Such an approach relies on various assumptions, such as that political parties ‘communicate their messages’ via party manifestosFootnote 4 or that there is no news media bias in reporting on parties. If, however, the latter is not the case, the information chain is not a constant but a media-specific one. The news media do act strategically, either to increase their audience share or represent a particular political position, and thus can alter the type and amount of information.Footnote 5 That party placement is endogenous to the media/information environment would have serious implications for any analysis that uses issue distance to predict vote choice: issue distance is then not simply a function of preferences but also of the amount and quality of information available about a party.
In this article we therefore examine how information exposure and the availability of information influence voters’ knowledge about parties’ policy positions. We argue that news media play an important role in translating the nature of party competition for voters, and that the amount of information on parties in news stories impacts voters’ knowledge about political parties. In other words, as most citizens’ experience of the political world is mediated, news outlets play an important role in translating the electoral supply of party alternatives to citizens, and where news media cues are stronger, citizens will be more knowledgeable about party positions – in the sense that they know better where parties stand on an issue. In environments that lack such information voters are more likely to remain uncertain about the policy positions of parties. Thus we examine a respondent’s ability to determine a party’s position on a particular issue based on the amount of information she has received about that particular party.
We analyse the impact of news media information imbalance on citizens’ information level by examining their ability to place parties on the issue dimension of European integration. Our method of analysis links news media content indicators of the information environment to the individual level, which includes – amongst others – measures of individual perceptions of party positions. We use a within-subject design in which we compare for the same individual how variations in news information about all parties influence knowledge levels.
We proceed as follows: we first provide a framework for understanding the impact of the news information environment on political knowledge. Our next step is to clarify our analysis, presenting the within-subject design in detail and developing a measure of knowledge about party placements. Finally, our results demonstrate that the news information context has a mediating effect on political party knowledge and find that, as suggested by past research, this is partly conditioned by the quality of news outlets. These effects are small, but nonetheless have important implications for the interpretation of vote choice models if we consider that media effects can have a cumulative impact.Footnote 6
THEORETICAL FRAMEWORK AND HYPOTHESES
Politically informed voters are more likely to participate in politics and have a better overview of politics and policies.Footnote 7 For spatial voting to work effectively, voters also need to be informed about the policy positions of the various parties running in the electoral competition. Voters with more information will be more likely to be certain about the different parties’ policy positions; they will also be more likely to place parties accurately on different issue dimensions and express an informed vote.Footnote 8 On the other hand, citizens with ‘more uncertain information are less likely to be able to base decisions on that information’.Footnote 9 Information will be particularly relevant when voters have to judge the position of more than two actors (for example, political parties and candidates).
Imperfect and incomplete information can manifest in different ways. First, a voter’s ordering of political actors based on electoral utility represents only a subsample of all available parties because a voter cannot calculate a utility if information on a party is missing. Citizens are then either forced to limit their options to this restricted choice set or rely on other cues and heuristics like party identification, candidate images or actor’s positions on other issues. This is not problematic per se, but due to the different origins and quality of information for different choice options, the decision-making process differs from a situation in which a citizen has information on all actors.
Secondly, a lack of information can also result in the misplacement of actors regarding their policy positions. For instance, Alvarez and Franklin show that a large proportion of respondents was not certain about the position of their own senator on particular policy positions, and that they were in general uncertain about the policy positions of the various political parties.Footnote 10 In these situations the working of the responsible party model is endangered: citizens’ policy positions communicated by vote choice will not result in correspondent policy decisions taken by the executive or legislative because the position of political actors differs from the perceived position of the voters that is used to determine the utility of different choice options.
Based on these severe consequences of information asymmetry across the set of party alternatives, we are overall interested in examining the mechanisms related to how voters become knowledgeable about party policy positions, but first and foremost, in exploring which role the media play in conveying information on party policy positions during a campaign. Gelman and King write that ‘information about candidates’ position on issues is […] the most important role of the media’Footnote 11 and we aim to examine whether (and under what conditions) the media can inform citizens about the policy positions of parties. Electoral campaigns are the ideal moments for information acquisition as elections are a priority for both parties and news media.Footnote 12 Based on these theoretical considerations, we test the following hypothesis:
Hypothesis 1: As information on party positions becomes more available, citizens will be better able to verify the accurate position of parties on issues.
While there may be some spill over of news information from personal discussions and social networks, we would not expect those who are not exposed to news media to be directly influenced by content.Footnote 13 In other words, the environment may be rich in information, but it will have little impact on citizens unless they consume it via a media outlet. Therefore, we test a second hypothesis:
Hypothesis 2: As information on party positions becomes more available, citizens who consume news on a daily basis will be better able to verify the accurate position of parties on issues than those who do not consume news content regularly.
There are reasons to expect that it is not simply the volume of information that matters but also the quality. In the growing body of comparative media effects research, one conclusion is that the quality of the news outlet – such as broadsheets and public service broadcaster (PSB) in comparison to tabloids or commercial broadcast – influences how informed voters are.Footnote 14 Citizens who obtain their information via quality news outlets might have a better understanding of the political space, as they are more likely exposed to policy-relevant news and party stances connected to it.Footnote 15 However, there is growing evidence that there are also knowledge gains for those who seek out information in low-quality sources, such as tabloids. Soft news with clear and easily accessible messages – and in particular, candidate appearances – in less serious news formats can serve to increase knowledge about candidates.Footnote 16 However, others have argued that soft news has a limited effect on political knowledge.Footnote 17 Therefore, our third hypothesis looks at the type of information, distinguishing between high- and low-quality information channels. We refrain from postulating a directional hypothesis due to contradicting evidence in other studies.
Hypothesis 3: The type of outlet in which information on political parties is retrieved affects knowledge of parties’ policy positions.
Analysing Media Effects by Linking News Content to Individuals
Because we want to understand how asymmetric information about parties in the information environment influences knowledge of political parties, we test whether watching or reading a particular news story alters what citizens know about political parties. Most studies that have sought to examine the impact of information levels on knowledge have tended to focus on how exposure to news, rather than the news content itself, has influenced political knowledge.Footnote 18 However, media are not neutral actors. They might privilege an issue or an actor relative to others, and report more about it. Therefore we examine both the individuals’ exposure to the news media and its content in order to capture potential different weights that news media assign to certain actors and their positions. Asymmetric information transmission is therefore inherent in the individuals’ news consumption.
Aside from ignoring the actual content of news, another issue in these studies is the problem of self-selection. Most research includes self-reports of exposure to news media and uses this to predict knowledge. However, we remain unsure about the causal direction when a relationship is uncovered:Footnote 19 Are more knowledgeable citizens more likely to seek out information than the less knowledgeable, or do news consumers become more knowledgeable from being exposed to news stories?
Within political communications research, it is understood that the only way to truly rule out the problem of self-selection and a spurious relationship is to employ experiments. However, we know that experimental settings do not accurately reflect how citizens encounter or engage with news media content in the real world, and scholars have started to question the size of effects detected in experiments and whether some types of experiments can rule out selection problems.Footnote 20
Because we are interested in how variations in the news environment affect knowledge, our approach more closely follows that employed by Barabas and Jerit and Jerit, Barabas and Bolson when linking news media content to knowledge measures.Footnote 21 Barabas and Jerit compare how variations in news information on a particular topic influence knowledge on the same topic for the same individual. This within-subject design holds constant the individual level variables that might be endogenous. In this approach, there is no control group; all experimental subjects (individuals) are exposed to each level of treatment of the treatment variable. Each individual is compared against her baseline, allowing the researcher to control for unobserved individual characteristics. By asking the same respondent to place multiple parties on a dimensional policy scale, we can assess, for each individual, how different levels of information about each party influence the placement of each party. For instance, for a single individual we can see if greater levels of information about Party A compared to Party B lead to a more accurate placement of Party A. If the level of information about a party produces differences in a single individual’s ability to place a party, we are able to draw a much more robust conclusion about the influence of news information.Footnote 22 Hence, the outcome is party placement and the treatment is the amount of information about the party. Our design lets us determine the impact of varying party-specific information in addition to constant effects.
If the news media coverage does influence knowledge of party positions, what effect size would we expect? And given our sample size, would we expect this effect size to be statistically significant? Generally, as suggested by Zaller, traditional election study sample sizes are not powerful enough to detect media exposure effects that may be small.Footnote 23 And media effect sizes, particularly those based on survey data, do tend to be small. Research on the media effects on antisocial behaviour demonstrates that effect sizes in laboratory experiments tend to be larger than those in surveys.Footnote 24 Hence, we expect that our media effects measured in observational data would even be even smaller. However, taking into consideration that media effects might be cumulative, even these small effects can be of relevance in the long run.
DATA AND METHODS
European Parliament (EP) elections are considered less important than national elections by both parties, in their efforts to communicate their policy positions, and the news media that dedicate less time and coverage to these events.Footnote 25 This lack of attention is likely to lead to an information asymmetry amongst voters.Footnote 26 While the relevance of the European issue has increased over time, citizens still clearly consider the left-right dimension to be more important; therefore it is less likely to represent a general orientation to political preferences or a heuristic for voters.Footnote 27 Thus information provided by news media might be particularly important to communicate parties’ policy positions on the issue of European integration. As such, it is an ideal case to analyse whether the media content we are interested in (news about Europe), is what voters are responding to.
In order to test our hypotheses, we rely on data from the European Election Study 2009 (PIREDEU).Footnote 28 The survey carried out immediately after the election in June 2009 provides the data on citizens’ placement of parties. Respondents were asked to place all relevant parties in their country regarding their positions towards the issue of EU integration on an eleven-point scale. It also includes all measures necessary to establish a fine-grained link with the media content data for each respondent. For each of the coded news media, respondents are asked whether they read/watch it, and if so, how many times a week. Furthermore, it provides relevant individual characteristic variables. Data on the media content analysis based on campaign news coverage leading up to the EP election is used to provide a direct measure of the amount of electorally relevant information about each political party. Over a three-week period, the content analysis was carried out on a sample of national news media coverage in all twenty-seven EU member states (comprised of broadsheets, tabloids, public and commercial broadcasts).Footnote 29 The overall television sample consists of fifty-eight TV networks and the overall newspaper sample includes eighty-four different newspapers.Footnote 30 Finally, data on parties’ positions on Europe is captured from the Euromanifesto database and the European Election Candidate Study.
Turning to the measures used in our model, we start with our dependent variable (Perception Gap): the gap between what we refer to as the empirically verified party position and a respondent’s perceived party positions on the issue of European integration. Respondents are more knowledgeable about a party the closer they are to estimating its verified position.
There is no consensus in the literature on how to obtain empirically verified party positions. Some studies use the average perceived party position calculated on the basis of mass surveys as a proxy for the verified position, while others work with expert judgements or data from candidate surveys and electoral party manifestos. Each approach suffers from drawbacks that might jeopardize the validity of our empirical results.Footnote 31 For our measurement of party positions we use the information provided by parties, namely from the candidate survey and the manifesto study, for a multiple imputation procedure to generate verified party positions for a large set of parties competing in the 2009 EP elections, which results in an efficient measure of party positions.Footnote 32
Figure 1 provides information on our dependent variable, Perception Gap. It shows the mean perception gap for each party covered in our analyses. In general, respondents are not able to accurately place parties on the EU issue dimension. The smallest average perception gap for a party exceeds one point on the scale, while for some parties the gap is almost five points.Footnote 33 That we find respondents who do not accurately perceive party positions is not surprising and fits well with the research showing that the EU dimension is less important, even in EP elections, than the left-right dimension. Given these large perception gaps, it is important to explore the factors that reduce the gap, particularly the influence of news media information.
Fig. 1 Mean perception gap for each party (with 95% confidence intervals) Note: the figure shows the average gap between the respondents’ placement of the party and the party’s verified position based on our estimation for each party (parties are sorted by the average size of the gap between their verified position and the respondent’s perceived placement of the party).
To measure the party-specific information available in the news environments, we focus on news stories from our media content analysis that mention the EU. Within each story we code the party associated with political actors that appear in the story. Our measure of the information available about a party in news stories is the total number of media mentions or ‘hits’ (excluding mentions of government ministers) that a party received in all news stories that mention the EU. Our measure of ‘media hits’ is intended to capture the amount of party information available that should assist voters in becoming knowledgeable about party positions on European integration. The more times a party or members of the party are mentioned in the news story about the EU, the more information about the party’s position on the EU should be available in the story.
This measure of media hits varies across parties in a country and news outlets such that we have media hits on parties in television broadcasts and newspapers across all member states. To capture decreasing returns of additional information on knowledge, in all models we use the log of media hits. To grasp the potential differences in information transmission based on the type of outlet, we calculate the media hits in high- and low-quality outlets by counting media hits by party in the different types of outlets. We provide a descriptive account of the number of media hits in Figure 2.
Fig. 2 Relationship between media hits in quality and non-quality news sources for each party Note: the figure displays the log value of the count of times a political party (a party actor or in its entirety) appeared in all news stories about the EU.
Clearly, there is a positive relationship between the two measures. Parties featuring prominently in one type of outlet are also more frequently featured in the other type. Moreover, the number of media hits varies substantially between parties, indicating that the amount of available information on different parties is far from universally equal and will vary considerably across an individual – which is a benefit of our within-subject design.
Our measure of a respondent’s media exposure is constructed from the voter survey: each respondent was asked to indicate the number of days she used the newspapers and TV news broadcasts coded in the media analysis. From this set of questions we constructed a measure of the days of media use overall, which is the maximum number of days consuming news in any of the outlets.Footnote 34 There are two advantages to our measure. First, we capture the probability of being exposed to the content we have coded. Secondly, asking respondents about specific outlets (for example, how many days a week spent reading The Guardian) minimizes over-reporting.Footnote 35 When modelling the impact of high- and low-quality news information, we create two separate exposure variables that capture exposure to the separate categories of news content. In the model, we link the amount of information available about a party and an individual’s level of exposure by interacting media hits with the maximum number of days spent reading or watching the outlets used to calculate the number of media hits.
Because a respondent may use an outlet other than the ones coded in the media analysis, we also include an exposure measure to news outlets other than those coded. The latter cannot be measured in days of media consumption because the data are not available in the voter survey. Here, we rely on a binary measure that identifies respondents who had exposure to uncoded news outlets and those who had not. In the analytical models focusing on either quality or non-quality news, this variable refers to whether a respondent is consuming non-quality news – in the model measuring the impact of quality news – or whether a respondent is consuming quality news – in the model measuring the impact of non-quality news.
We also include a set of control variables at the party, individual (subject specific) and country levels to ensure that any evidence of media effects is not a mere consequence of an omitted variable bias.Footnote 36 On the party level, we control for incumbency, as the positions of incumbent parties might be perceived as more certain. At the individual level, we include voters’ political interestFootnote 37 and level of EU identity, and take into account how likely a respondent says she is ever to vote for a party (propensity to vote): those who are likely to vote for a party might be more likely to know where it stands on the issue of Europe. Additionally, we include a measure that identifies respondents with problematic answering patterns such as assigning the same position to all parties. Finally, on the country level, we include a measure of programmatic diversity and the effective number of electoral parties. The coding for all variables is given in Table 1.Footnote 38
Table 1 Operationalization of Variables
RESULTS
Media Effects on Party Placements Knowledge
Following the necessities of a within-subject design and acknowledging the potential importance of contextual factors, we set up a three-level data structure. To perform our within-subject design, the lowest level (party level) is nested in the level of individuals (respondent level), and the latter is nested in the contextual level (country level). Therefore, the data structure resembles a stacked data matrix with a comparative framework that has been commonly used to analyse, for example, party choice.Footnote 39
We do not restrict the sample to specific parties or just voters. However, the need to match four different datasets results in the loss of some cases, especially at the party level. Moreover, respondents drop out due to missing information on some of the control variables used. Still, our analysis covers 174 parties, 19,233 individuals and twenty-eight countries.Footnote 40 The overall number of cases on the lowest level is 107,822 (which is equivalent to the sum of parties rated by all respondents in all countries). All models presented below are linear random intercept three-level models applying full maximum-likelihood estimation.
Even though perception gaps are quite large, does the availability of party news media and media consumption decrease those gaps? In order to examine these effects, we ran five different models: an intercept-only model (null model), two models for all media hits, one without (Model 1a) and one with interactions (Model 1b), and two models differentiating between quality and non-quality media hits (Models 2 and Model 3).Footnote 41 The results are presented in Table 2. Based on the null model, we calculated the intra-class correlations (ICC) for both higher levels. The ICC for the respondent level is 0.20, which means that about one-fifth of the variation regarding the gap between verified and perceived party position is located between individuals. Only 5 per cent of the variation is located on the highest level (between countries). Hence, more than 70 per cent of the variation is within subjects (between parties).Footnote 42
Table 2 Party Placement Knowledge and News Information: Explaining the Gap between Verified and Perceived Party Positions
Notes: ARefers to all media hits in Models 1a and 1b, media hits in quality outlets in Model 2 and media hits in non-quality outlets in Model 3; BRefers to consumption of coded outlets in Models 1a and 1b, consumption of quality outlets in Model 2 and consumption of non-quality outlets in Model 3; CRefers to consumption of uncoded outlets in Models 1a and 1b, consumption of non-quality outlets in Model 2 and consumption of quality outlets in Model 3; *p<0.05; **p<0.01; ***p<0.001.
As is evident in Table 2, any given model is only able to explain a small amount of the dependent variable’s variation. Based on the comparison of the error variance components of the explanatory models and the null model, the R2 values are always close to 0.05. However, the models are rather parsimonious and a low R2 value is common when applying regression estimation to extremely large samples. Moreover, the R2 values are no indication as to whether the causal mechanisms regarding media effects have to be rejected or not.
As stated, we are also interested in the effect of media hits conditioned by media consumption on respondents’ capacity to locate parties correctly on the issue of EU integration. Consequently, these variables are introduced as part of cross-level interactions in Models 1b, 2 and 3, making it rather unhelpful to interpret regression coefficients or significance levels as presented in Table 2. Instead, we interpret them on the basis of marginal effect plots.
Turning to the control variables first, we find a very stable pattern over all explanatory models. On the party level, both a higher propensity to vote (PTV) for a party and incumbency in the national arena decrease the perception gap significantly. The more likely it is for a respondent to vote for a party, the better is her knowledge of the party’s policy position. This is good news for the link between electoral competition and meaningful choices: all other things equal, respondents know more about parties that they actually consider voting for. This is perfectly rational in a world of limited resources and, in particular, the low information environment surrounding second-order elections. Moreover, the position of parties in government is better known, which could be a direct consequence of policies – even on EU issues.
On the respondent level, individuals classified as guessing party positions produce – unsurprisingly – larger gaps between verified and perceived positions, whereas the more politically interested and those identifying as European are more likely to correctly place parties. Consistent with past research, individual-level factors do a substantial job of explaining the variation in knowledge (in our case, party knowledge). It has to be noted, though, that we find much weaker effects of political interest in Models 2 and 3. In the latter, the coefficient is not significant.
On the country level, neither the diversity of party placements nor the effective number of electoral parties has a significant effect on the perception gap. Taking into account the rather low ICC on the country level, it is not surprising that country-level variables have no effect on the gap between perceived and verified party positions.
What do our results show about the effect of media hits and media consumption on the perception gap of party positions? One of our main variables of interest is the amount of information about a party in the media. The results of Model 1a are consistent with Hypothesis 1: the more information about a party – defined as media hits – available to a respondent, the better able she is to place the party. For the same individual, the more prominently a party features in the media, the smaller the gap between the verified position and the respondent’s placement of that party. Put differently, given our within-subject design, for this same respondent, the gap, on average, widens when less information is available about another party. This main effect of media hits does not depend on the nature of the source: we get significant and negative coefficients regarding media hits in general as well as for media hits in quality and non-quality outlets (Models 2 and 3).Footnote 43 The marginal effects plot on the lower-right corner of Figure 3 further supports this conclusion.Footnote 44 Furthermore, the effect is, in absolute terms, larger for non-quality outlets. With regard to Hypotheses 3, we conclude that while both types of media hits decrease the perception gap, the information provided by non-quality outlets has a significantly larger effect, which might be due to the larger quantity of soft news.
Fig. 3 Marginal effects of media hits and consumption on perception gap
Turning to media consumption for the coded content, Models 1a and 1b measure the highest number of days per week on which any of the coded outlets is followed. For Models 2 and 3, we restrict the outlets considered to quality and non-quality outlets, respectively. For all models with interactions, media hits and consumption of coded outlets should be considered together: thus, we specified an interaction term capturing how consumption conditions the impact of party visibility in the media (see Hypothesis 2). In Model 1b, which does not distinguish between media outlets, the interaction term is not significant. However, when we look at Models 2 and 3 we find evidence for both Hypotheses 2 and 3: we see the differential impact of types of information and consumption. Quality information does not only reduce the gap, but given the negative coefficient for the interaction term, quality information reduces the gap even further the more respondents are exposed to it. Yet while information in non-quality outlets overall reduces the gap to the largest extent, the positive interaction term reveals that more frequent consumption of non-quality news reduces this effect: it narrows the gap such that higher levels of consumption of low-quality news have minimal effects on knowledge about party placements.
The marginal effects of a one-unit change in media hits for different levels of consumption are displayed in the upper plots as well as the lower-left plot of Figure 3. These effects provide information on significance levels conditioned on days of consumption and enable comparison between different numbers of days. The first graph displays an almost flat marginal effect: there is no change in the effect of media hits as consumption of all media increases. This would suggest that Hypothesis 2 cannot be confirmed. However, in the graphs differentiating between types of outlets, in the upper-right plot we see that as the consumption of quality news outlets increases, the gap between the verified party position and the respondent’s placement decreases. In the lower-left graph on non-quality outlets, we see the opposite marginal effect: the impact of party visibility on reducing the gap between the respondent and the verified placement diminishes as consumption of non-quality news increases. Note that these effects are only significant if we compare no or low consumption to high levels of consumption. These results make it necessary to state Hypothesis 2 more precisely: the more often quality news is consumed, the better the ability to place a party correctly. However, this does not apply to non-quality news information, where we find a decreasing effect with higher levels of consumption. Hence, it is more about quality than quantity of information. This finding is further supported by the indicator on media consumption for non-coded outlets. As described above, we include a dummy variable indicating whether the respondent consumes other (uncoded) media outlets: these are non-quality outlets for respondents consuming quality outlets (Model 2) and quality outlets for respondents consuming non-quality outlets (Model 3). In Model 2, we find that such consumption increases the perception gap, while there is a negative coefficient in Model 3. In substantive terms, the consumption of non-quality outlets in addition to quality outlets makes it more difficult for respondents to locate parties, while it is the opposite for the additional consumption of quality outlets.
Taking these findings together, we demonstrate a somewhat complicated picture that, nevertheless, seems to be a valid representation of prior studies on the differing effects of quality and non-quality outlets. The difference between the outlet types is much more prominent in regard to consumption patterns (Hypothesis 2), meaning that, all in all, the consumption of quality outlets decreases the perception gap to a larger degree than the consumption of non-quality outlets. Having said that, the information provided in non-quality outlets has a larger impact on the perception gap than its quality counterpart (Hypothesis 3).
CONCLUSION
The analysis we present has contributed to the scholarly debate on media effects on political knowledge. We have argued that where information is asymmetric about political parties, this has implications for models that use respondents’ placement of parties in predicting vote choice. We have demonstrated that respondents are more likely to place parties closer to their verified position when more information is available. Our analysis shows that the news media play an important mediating role in supplying voters with this information. Our findings of a significant but small effect for the information environment reflect the complex array of factors that influences knowledge, but given the cumulative effect of news media information, these effects are supposed to exert an increasing, consistent influence in the long run. Furthermore, given the increasing number of news articles about the European integration project,Footnote 45 and hence the increasing availability of EU news, we assume the effect will become stronger in the future.
As in other research where findings across types of outlets is not consistent, we find, on the one hand, that while available information reduces the perception gap in general, this effect is stronger for low-quality information. On the other hand, consumption of non-quality news – and, by consequence, low-quality information – reduces the gap between verified and perceived positions, but the effect gets smaller the more often an individual reads non-quality press or watches non-quality news programmes. Hence, while we can observe an overall soft news effect for non-quality outlets, which provide easily accessible and new short messages, the more complex analytical news in quality outlets can unfold a stronger effect the more individuals are exposed to them.
Our analysis has also extended the use of a within-subject design to test media effects cross-nationally. It allows us to arrive at more robust findings regarding the impact of information on knowledge about party positions. The design provides the possibility of testing how different levels of information about parties can lead to, within the same individual, different levels of knowledge about political parties. In this way, we have controlled for problems with self-selection and other confounding factors because they will be constant across individuals. This is a useful design, therefore, when using observational data.
Turning to the issue of European integration, a number of studies show that when the EU is more visible in the news or salient in a country, voters give greater weight to the distance they have from the government party on the EU dimension.Footnote 46 Our findings suggest that the actual distance a voter may perceive herself from a party is endogenous to the information environment because it provides – to a varying degree – resources to locate parties correctly. More knowledgeable, and hence reliable, EU issue distances are produced for more visible parties. Therefore, that party positions are more salient when there is more information may be an effect of learning rather than EU issue priming.Footnote 47 As information is not equally available for all parties, this effect varies, and parties’ EU issue positions will impact vote choice models differently. In other words, the utility of voting for a certain party with regards to the issue of EU integration varies due to the amount of available information and the source’s quality.
How can these results be generalized? Given the fact that parties and the news media put greater emphasis on issues that are already available in their electoral campaigns, the knowledge gains should be even larger in contexts with longer and more intense campaigns compared to the European Parliament elections.Footnote 48 This applies to both general elections and issue dimensions such as the left-right dimension. Overall, knowing more is not just a desirable goal; it also makes voters less likely to feel disappointed with their vote choice during the election period.
