"Data Still Needs Theory: Collider Bias in Empirical Legal Research"

Abstract: Big data is characterised not only by the amount but also the kinds of information that can be created, stored, and processed. This explosion of data, accompanied by the capacity to analyse them, has catalyzed large n, quantitative approaches to the study of law and legal institutions. But neither size nor quality guarantees the validity of causal inferences drawn from observational data. For example, although the inclusion of control variables can help isolate causal effects, not all variables are good controls. Bad controls are not harmless and can create the impression of a causal relationship where none exists. This spurious association is called collider bias. We introduce the concept of collider bias and give motivated examples of how it can arise in empirical legal research. The selection of good controls requires knowledge and assumptions about causal structures. Theory and domain knowledge are essential for quantitative analysis, even in the era of big data.

‘Shahla Ali's work is an innovative meta-analysis of the trends in the institutionalization of mediation at the macro level. It has an ambitious approach that had not been attempted yet, and paves the way for other future research, as well as providing guidance to policy makers and professionals.’ – Luigi Cominelli, The University of Milan, Italy‘Professor Shahla Ali has performed a valuable service for conflict resolution policy makers around the world. Providing diverse and mixed data reports of the uptake and resistance to court (and some private) mediation programs in ten different legal systems, she artfully surveys important legal, social and cultural differences in the uses and effectiveness of voluntary and mandatory mediation programmes. While some seek efficiency, others seek efficacy, through party-tailored solutions or regional integration dispute resolution schemes. Different programme motivations (and the varied role of lawyers) provide variation, not uniformity, in the use of mediation to resolve civil, family, labour and commercial disputes. A must-read for any dispute system designer, or court administrator or mediator.’ – Carrie Menkel-Meadow, University of California, Irvine and Georgetown University Law Center, US‘Professor Ali's book offers the most comprehensive, qualitative study and insights on Global Court Mediation I have encountered. It should be in the hands of every court in the world.’ – Judge Dorothy Nelson, United States Court of Appeals, 9th Circuit
