Politics and Policy Pre-Analysis Plan (PAP) Workshop

Tuesday 4 July 2023
Turfmarkt 99
2511 DP The Hague

An increasing number of scholars at Leiden are using experimental methods to study topics in politics and policy. One challenge of experimental methods is that a considerable amount of work must be done before data is collected and there are few opportunities to fix errors or shortcomings once an experiment is in the field. Further, there are few opportunities to get feedback when it is most important as most conference outlets frown upon the presentations of research designs.  

To help remedy this problem, we are organising a workshop to allow researchers working at Leiden the opportunity to present and get feedback on their research designs before they are fielded.

At the final workshop of this academic year, we’ll host a guest lecture by Professor Kevin Cope and discuss pre-analysis plans of two scholars.


13:00—13:45 hrs Prof. Kevin Cope with the guest lecture on Experimental Studies on the Normative Force of Law: The Problem of 'Treatment Resistance'
14:00—14:25 Prof. Mila Versteeg with the PAP on 'Unpacking the Rule of Law: A Survey Experiment'
14:25—14:50 Dr Marion Collewet with the PAP on 'Financial innovation: a checking account to help people not have so much month left at the end of the money'

Experimental Studies on the Normative Force of Law: The Problem of 'Treatment Resistance

An important question in legal theory and policy is under what conditions are people willing to put aside their policy preferences to uphold higher-order legal values? That is, when does constitutional or international law have 'normative force'? Around two dozen experimental studies have attempted to measure this question empirically, but their designs contain an inherent limitation: respondents in the treatment group whose priors are strongly contrary to the treatment message on the legality of a policy are effectively 'treatment resistant': it is difficult to successfully treat them. Where a significant portion of the treatment and/or control group is not successfully treated, the results will be biased towards a null finding. In this lecture, Professor Cope will talk about models underlying the problem of 'treatment resistance' and will demonstrate an actionable solution to this problem.

Professor Kevin Cope

Professor Kevin Cope is a legal scholar and political scientist whose research investigates legal and political decision-making using empirical, comparative, and formal theoretical methods. Substantively, he is most interested in immigration, international political economy, human and civil rights, and judicial ideology. Cope is the past co-president of the Society for Empirical Legal Studies and a co-editor of the inaugural Oxford University Handbook on Comparative Immigration Law.

Cope’s work is published in journals such as the Journal of Legal Studies, Journal of Theoretical Politics, Political Science Research and Methods, Journal of Empirical Legal Studies, Michigan Law Review, American Journal of Comparative Law, and American Journal of International Law. He is also widely published in popular press.

Cope earned his J.D. from Northwestern University School of Law, his Ph.D. in political science from the University of Michigan, his LL.M. from Georgetown University Law Center, and his B.A. from the Ohio State University.
