Using Principal-Agent Theory, our new paper argues delegating governmental tasks to #AI undermines feelings of being in control, leading to a "failure-by-success": Initial AI efficiency drives wider adoption, ultimately eroding citizens' sense of control, a cornerstone of democratic legitimacy

As part of our ECPR GC24 section, we will also organise a methods panel called ‘Anatomies of Methodological Failure’, chaired by the brilliant Petro Tolochko, where we want to discuss failures in projects using computational methodologies. CSS Polsky Commsky 👉 bit.ly/polcomm-ECPR
This panel implements a novel approach by hosting presentations on failures in methodologically novel research enterprises. This includes, for example, computational text analysis, agent-based modelling, or exponential random graph modelling. The aim of the panel is to provide room for learning and understanding the promises and pitfalls of new methods increasingly shaping political communication research. Please send us a short description of what you intended to do, including the research interest (broadly stated or a more explicit research question), the data you wanted to analyse and the method(s) you wanted to apply, and how this did not work out, i.e., what the problem was and how/why you could (not) fix it.
