During the 2016 US elections, a popular quiz circulated on Facebook and other social media platforms. The quiz asked twenty single-sentence questions about the quiz-taker's views on various aspects of foreign and domestic policy, taxation, immigration, and government spending on health and education. At the end, it provided a chart, showing the political position of the quiz-taker as well as those of the candidates, allowing the quiz-taker to see with whose policy positions s/he most closely aligned.
Other versions of this quiz created a graph with authoritarianism/libertarianism on the x axis and left/right-wing bias on the y axis. It then displayed a number of politicians: Bernie Sanders, Hillary Clinton, Donald Trump, and so on along with the position of the quiz-taker as revealed by his/her answers. Yet another, simpler version gave a single answer, telling the quiz-taker which politician best represented his/her views and then listing all that person's major policy positions.
Some version of a quiz like this, which people can take online on their computers or phones and which only takes a few minutes to complete could provide a highly effective method first of making people think about the policy areas that are really important to them and what they actually believe (and an understanding of which candidates support these positions and what they pledge actually to do in office). A simple quiz on all policy areas could then lead to other quizzes with a more detailed analysis of specific policy areas, and it could perhaps include a link to a website where the policy positions of each candidate are clearly and simply outlined.
