Generalized Additive Model

The GAM model is specified with a standard smoothing spline, which enables us to estimate the smoothed nonlinear cohort effects. By applying this specification, we assume that the cohort effect is smoothly changing. We follow Grasso by including age as a categorical variable with three levels (15-29, 30-59, 60+) and control for period specific differences as fixed effects (Grasso, 2014):

Robust Hierarchical APC Model

We used the robust HAPC technique (Bell and Jones, 2015) and work with the assumption that period trends are absent when examining citizenship norms over time. We included birth cohorts as random and fixed effects, which constrains period trends to 0 (Bell and Jones, 2015: 203). Still, period effects can to arise from the respondents’ social context, since they are included as random effects. We thus model respondents as nested in cohorts and periods as their distinct social contexts. In order to “assess the relative importance of the two contexts, cohort and period, in understanding individual differences” (Yang and Land, 2006: 87), we treat periods and cohorts as independent random variables (assuming a person born in 1965 might have been surveyed in either 2008 or 2017). This assumption is necessary because any combination of the two levels is conceivable (Rabash and Goldstein, 1994; Rabe-Hesketh and Skrondal, 2008: 473). Finally, due to the simultaneous occurrence of age, cohort and period effects, every APC statistical model requires the assumption that there are no countervailing temporal influences, which offset the impact of the other temporal effects.

This specification is embedded in country fixed-effects multi-level regressions to account for different levels of norm acceptance in each country. In line with common practice (Dalton, 2008b; Yang and Land, 2006), we controlled for gender. As HAPC models may provide misleading results for linear cohort and period effects (Bell and Jones, 2017), we avoided the assumption of linear effects by including age and cohort terms with polynomials on the second and third order. Further, we divided cohorts into independent groups, separated into 17 categories by the five-year span when the individuals turned 18. For each dependent variable and each country, we ran robust cross-classified hierarchical age-period-cohort mixed regression with the following specification (Bell and Jones, 2015):

On Dec 12 2018, we pre-registered research questions, indicators of interest and the analytical strategy. In addition, we pre-specified all details of the model specification by pre-registering the analytical code. The pre-analysis plan can be found here [Link to be included after peer review is concluded].

In a small number instances, the final analyses as reported in the manuscript deviates from the pre-analysis plan (PAP). In this appendix, we document and justify the deviations.

Country selection

In the PAP, we pre-registered several scenarios for how to report the results from the large number of country-samples. Adhering to what was pre- registered as preferred option, we report results for all democratic countries that are available in the EVS 2017 pre-release. As a secondary option we had pre-registered the option to report aggregated results for all countries or to report results for subgroups of countries. Yet, it was possible to report the evidence for all countries separately which was pre-registered as the preferable alternative.

Indicators

We registered attitudes towards expert governments as a primary variable of interest, attaching it the same status as attitudes towards authoritarian governments. However, in the main text we only plot attitudes towards authoritarian governments and we mention only briefly attitudes towards expert governments. Due to limitations in space, we decided that two analyses on abstract regime preferences (democracy, authoritarianism) would be sufficiently informative, considering that indicators on other types of attitudes should also be reported.

Note that the development of attitudes towards expert governments followed a similar trajectory as those indicators that are reported in the main text: there are no clear time trends or evidence for generational trends in direction of the democratic deconsolidation hypothesis. There is considerable increase for expert governments in the Netherlands and Switzerland which may deserve further country-specific attention. At the same time, there is generational decline in the acceptance of expert governments in Poland and considerable time trends in the same direction in Germany.

Predictions

In the pre-registration plan (and in the accompanying analysis syntax), we did not clearly specify the scenarios underlying the predicted mean attitude levels which are reported in the plots. We decided to set the scenario to the latest wave of the EVS (EVS 5), a female respondent, the average year in which the respondents turned 18 and the average grouped cohort year in wave 5 for the life-cycle effects. For the cohort effects, we only replaced the average year in which the respondents turned 18 with the average age group in wave 5.

Title

Essential to live in a country that is governed democratically, by age cohort

Original Interpretation

When asked to rate on a scale of 1 to 10 how essential it is for them to live in a democracy, 72 percent of those born before World War II check 10, the highest value. So do 55 percent of the same cohort in the Netherlands.

But, as Figure 1 shows, the millennial generation (those born since 1980) has grown much more indifferent. Only one in three Dutch millennials accords maximal importance to living in a democracy; in the United States, that number is slightly lower, around 30 percent.

Title

Having a democratic Political System is a bad or very bad way to run this country

Original Interpretation

The decline in support for democracy is not just a story of the young being more critical than the old; it is, in the language of survey research, owed to a cohort effect rather than an “age” effect. Back in 1995, for example, only 16 percent of Americans born in the 1970s (then in their late teens or early twenties) believed that democracy was a bad political system for their country. Twenty years later, the number of antidemocrats in this same generational cohort had increased by around 4 percentage points, to 20 percent. The next cohort—comprising those born in the 1980s—is even more antidemocratic: In 2011, 24 percent of U.S. millennials (then in their late teens or early twenties) considered democracy to be a bad or very bad way of running the country. Although this trend was somewhat more moderate in Europe, it was nonetheless significant: In 2011, 13 percent of European youth (aged 16 to 24) expressed such a view, up from 8 percent among the same age group in the mid-1990s (see Figure 2).

Our Assessment

In our data, there was a period effect between 99 and 2008 that may partially account for the findings in Figure 2.

However, in our data the period effect occured only in: Austria, Bulgaria, Croatia, Czech, Republic, Netherlands.

Examining the presence of period effects when only considering countries that were included in the Foa Mounk analysis: declining period effect were found in the 2000s in: Netherlands no period effects in 2000s in: Poland, Germany very small effects in: Spain not in our sample: Romania, UK

In general: these investigations shows that there is not a lot of overlap between the country sample underlying Figure 2 and the country sample underlying our study

Title

The widening Political Apathy Gap

Original Interpretation

In fact, in both Western Europe and North America, interest in politics has rapidly and markedly declined among the young. At the same time, it has either remained stable or even increased among older cohorts. In 1990, both a majority of young Americans (those between the ages of 16 and 35) and a majority of older Americans (36 years and older) reported being fairly interested or very interested in politics—53 and 63 percent, respectively. By 2010, the share of young Americans professing an interest in politics had dropped by more than 12 percentage points and the share of older Americans had risen by 4 percentage points. As a result, the generation gap had widened from 10 percentage points to 26 percentage points. Among European respondents, who on the whole report less interest in politics than do their American counterparts, this phenomenon is even starker: The gap between young and old more than tripled between 1990 and 2010, from 4 to 14 percentage points. This is attributable almost solely to a rapid loss of interest amongyoung respondents. Whereas the share of Europeans aged 36 or older who were interested in politics remained stable at 52 percent, among the young that figured dropped from 48 to 38 percent

Our Assessment

one partial explanation of discrepancies between Figure 3 and our study might lie in the complex S-shaped curves in the developmeht of political interest across generations that our study has revealed and that is not visible in the Foa Mounk analysis as they dichotmized generation membership/age-groups.

In addition, we observe a small uptick among the very young generations and the Foa Mounk data does not cover that because we use a more recent data source

Title

Support for autoritarianism by income in the US

Original Interpretation

In the United States, among all age cohorts, the share of citizens who believe that it would be better to have a “strong leader” who does not have to “bother with parliament and elections” has also risen over time: In 1995, 24 percent of respondents held this view; by 2011, that figure had increased to 32 percent. Meanwhile, the proportion of citizens who approve of “having experts, not government, make decisions according to what they think is best for the country” has grown from 36 to 49 percent. One reason for these changes is that whereas two decades ago affluent citizens were much more likely than people of lower income groups to defend democratic institutions, the wealthy are now moderately more likely than others to favor a strong leader who can ignore democratic institutions (see Figure 4 below).

Our Assessment

Figure 4 only concerns the US which is not included in our sample. As noted by Norris (2017), the signs of democratic deconsolidation that can be observed in the US do not occur at the same magnitude or not at all in other (European) countries. Yet, Europe is the focus of our analysis.

Title

Across the globe, the young are less invested in democracy

Original Interpretation

It is not just that the proportion of Americans who state that it is “essential” to live in a democracy, which stands at 72 percent among those born before World War II, has fallen to 30 percent among millennials. It is also that, contrary to Ronald Inglehart’s response to our earlier essay in these pages,3 a similar cohort pattern is found across all longstanding democracies, including Great Britain, the Netherlands, Sweden, Australia, and New Zealand (see Figure 1). In virtually all cases, the generation gap is striking, with the proportion of younger citizens who believe it is essential to live in a democracy falling to a minority.

Global rise in share of citizens wishing for a strong leader who does not have to bother with elections

Original Interpretation

The share of citizens who approve of having a strong leader who does not have to bother with parliament or elections, for example, has gone up markedly in most of the countries where the World Values Survey asked the question—including such varied places as Germany, the United States, Spain, Turkey, and Russia.

Our Assessment

All analyses are based on extremely small sample sizes but the figure does not show uncertainty of the estimates.

The analysis does not take into account the possibiltiy that acceptance of democracy increases in both age-groups. In such a case (which is a frequent occurance in the data we analyzed) the analyses presented in Figure 2 is somewhat misleading.

Support for Democracy among European Youth (16-26) Respondents, 1999-2001 and 2017

Original Interpretation

In three countries (France, Italy, and Poland), only a minority of those aged 16 to 26 view democracy as the best form of government. In the UK, just over half of young respondents take this view. Even in Germany, which has so far shown less strong democratic deconsolidation than other countries, only about three in five respondents believe this
