Presentation LMU Munich Titel Living in Novaland: can we Simulate the Experience of States and Public Policies in an Artificial Online State? Achim Goerres, University of Duisburg-Essen What if we could experimentally manipulate all characteristics of states and public policies and estimate their effects on citizens? This presentation puts forward the first evidence from a pilot of Novaland. Novaland is an artificial liberal democracy that only exists online and that has characteristics realistically drawn from German, Romanian and US contexts. The pilot consists of an experimental online platform based on text, images and audio in which volunteers (a) are surveyed before they go into the experience, (b) are randomly assigned to different experiences, such as defined by income, quality of government or state corruption, (c) interact with each other simultaneously and (d) thereby co-create collective decisions, such as elections or donation pools, that then determine the course of Novaland and thereby the subsequent experiences of the participants. The pilot gives us many insights into the usefulness of such full experiential simulations in the social sciences. Can this technically and organizationally be done? Do participants behave in an externally valid manner? Do they behave sincerely? What is the potential of such an approach for finding causal effects? The project is financed by a Consolidator Grant of the European Research Council. More details about the project at https://bit.ly/politsolid and about the presenter at www.achimgoerres.de
