1. Introducing empirical legal research
and structure of the book*
1.1 AN APPETIZER
Characterizing empirical legal research (abbreviated as: ELR) for lawyers,
legislators and regulators is not that easy. One reason is the difference
between the way lawyers and ‘empiricists’ think.
While both modes of thinking are grounded in rigorous analysis, lawyers and
empiricists often have different goals and approaches. Legal analysis places
a premium on argumentation and appeals to authority, is frequently geared
toward proving a particular view, is often focused on the particulars of an
individual case, and is directed at reaching a definitive conclusion. In contrast,
empirical analysis places a premium on observation, challenges assumptions, is
oriented toward the testing of hypotheses, is usually focused on describing pat-
terns that operate in the aggregate, and is a continuing enterprise in which new
work builds on that which came before and generates even more questions for
further investigation. (Lawless, Robbennolt and Ulen, 2010:10)
Although this contrast is exaggerated, there are notable differences between
the two types of work.
A second reason why a characterization is difficult is that ELR makes
it necessary to consider topics that students, scholars and practitioners of
law are often not acquainted with. When you hear about empirical legal
research, you probably think about data and how the data was collected.
You will wonder how the (legal or societal) problem at hand was ‘trans-
lated’ into a research(able) problem. One of your colleagues may ponder
the design of the study and the relationship between the ‘legal’ (normative)
part and the ‘social sciences’ part. Can they be bridged? It would not be
bad guesswork to think that discussions were held on what the ‘units of
analysis’ are (offenders, victims, business contract partners, judges, civil
servants, courts, asylum seekers, or internet service providers) and whether
or not ‘we will work with a sample and use statistics’. The same goes for the
researcher-j urist who is given the task to find relevant research evidence
from the past. Finally, on a dog’s day afternoon, there is that young assis-
tant visiting Wikipedia, trying to understand the role of ‘theories’ in the
current project, probably wondering what is meant by the word. Purely by
