3 … Evidence-Based Jurisprudence meets Legal Linguistics. Unlikely Blends Made in Germany, BYU L. Rev. 43 (2018), S. 1473–1501, gemeinsam mit Friedemann Vogel

German legal thinking is infamous for its hair-splittingly sophisticated dogmatism. Some of its other research contributions are frequently overlooked, both at home and abroad. Two such secondary streams recently coalesced into a new corpus-based research approach to legal practice: Empirical legal research (which had blossomed in Germany already by 1913) and research on language and law (following German pragmatist philosopher Wittgenstein 1922). The article introduces these research traditions in their current German incarnations (Evidence-Based Jurisprudence and Legal Linguistics) and shows how three common features – their proclaimed pragmatism, their skepticism towards legal authority and their big data strategy – inspired a new corpus-based research agenda: Computer Assisted Legal Linguistics (CAL²).

2 … Unpacking the Board. A Comparative and Empirical Perspective on Groups in Corporate Decision-Making, BBLJ 11 (2014), S. 1–54

Collegial decision-making is relevant for a host of legal questions and in particular for corporate law. What do we know about its empirical effects? Less than we could. As of yet, pertinent review articles usually (1) assume rather than analyze how much the law actually mandates collegial decision-making, (2) rely mostly on “classical” studies of decision-making or those from behavioral economics, while underrating a century’s worth of previous empirical research, and (3) review the evidence anecdotally with little regard for the robustness of each study’s findings. As a consequence, scholars from corporate law and economics even today rely on theories and evidence which were disproved years ago. The present paper is a remedy. It combines a thorough comparative analysis of corporate statutes with a comprehensive research of empirical evidence, resulting in an assessment of the robust empirical effects of collegial decision-making. Finding that groups tend to deteriorate decision quality and exacerbate cognitive biases, this paper calls upon corporate law to design institutional remedies. Knowing more about these empirical effects will help scholars to identify and eliminate faulty arguments, and thereby improve governance policy and the legal discourse as a whole.

1 … Juristische Eselsbrücken. Anregungen zum Einsatz der Mnemonik im Rechtsstudium, StudZR 7 (2010), S. 125–143

Von allen Arbeitsmitteln des Juristen ist sein Gedächtnis wohl das wichtigste, zumindest vor dem Examen. Dennoch investieren Jura-Studenten weniger als Studenten anderer Fachrichtungen in die Förderung ihres Erinnerungsvermögens. Dabei haben Psychologen längst wissenschaftlich fundierte Untersuchungen über mnemonische Lernhilfen vorgelegt. Der folgende Text befasst sich erstmals im juristischen Schrifttum mit diesem Thema und bietet einfache Eselsbrücken zur Bewältigung juristischer Lerninhalte an. Eine zumindest grundlegende Beschäftigung mit Mnemonik ist jedem Studenten anzuraten; sie ist Lernhilfe und soft skill zugleich und schafft freie Zeit für die wirklich interessanten juristischen Probleme.
