The first aim of the project is thus to gather data on equality concepts of parties in ten OECD countries since 1980. For instance, parties could focus on equal chances, equal rights, or economic equality. The categorization is done via online crowdcoding of political texts. Every text fragment is repeatedly coded by multiple crowd coders until an agreement threshold is reached – following the idea of the wisdom of the crowd, according to which the aggregation of independent judgments by non-experts can match or outperform real experts. Previous work by the group leader has looked at the scope conditions under which the results of the crowd can match the results of experts for complex tasks. Based on 5000 test questions calibrated by the research group, the category scheme consisting of various equality  concepts will be “scaled up” to 1 million coder decisions in a reproducible manner.

This interplay of the crowd and experts will result in a database that allows the research group and the interested public to compare dominant equality concepts between parties, countries, and over time. For instance, we will test the assumption that (certain) parties have abandoned material equity.

The second aim is to find out how differences in equality concepts affect political decisions and – eventually – a broad set of (mostly economic) inequality outcomes. We draw on regression analyses and case studies in politically and economically diverse settings to decipher distinct pathways to (in)equality; i.e., different combinations of equality concepts, policy profiles, and inequality patterns.
