Mind That Gap: What PIAAC Has to Say on Why and Where Education is Associated with Political Efficacy
Francesca Borgonovi & Artur Pokropek
Philosophers from Aristotle to Rousseau have held the belief that functioning democracies are founded on

Countries differ in overall levels of political efficacy…
Figure 1 illustrates large differences between countries in the extent that individuals agree/disagree that people like them have no say in what the government does. Can PIAAC say anything about why in some countries political self-efficacy is comparatively high and in others it is comparatively low? We find that, in countries where individuals have higher levels of literacy and numeracy, political efficacy is higher. Interestingly, there is no statistically significant association between political efficacy and key features of the political system such as high levels of respect for the rule of law, low levels of corruption, high levels of GDP per capita and electoral rules (e.g., first past the post, majority systems or proportional systems).
… but also in how polarised levels of political efficacy are
Successful democracies involve all citizens in decision making. Our study shows that the importance of cognitive abilities in explaining differences in political efficacy differs systematically across countries. Some contries manage to involve all citizens. In others, citizens with low levels of literacy and numeracy are only involved to a small extent. A key finding is that, in countries with high quality public institutions, cognitive abilities play a less important role in explaining who expresses political efficacy than in countries with lower quality public institutions. In constrast, cognitive abilities play a very important role in countries with proportional representation and a minor role in countries with first-past-the-post or majority representation. These results suggest that the development of political efficacy is closely tied with the cognitive capacity individuals have to evaluate information.
Winner-take-all systems are simple and transparent, since the number of political parties is small compared to the number of potential electoral choices enjoyed by systems opting for proportional representation.
