Persuasion in the Courtroom
William C. Costopoulos*
INTRODUCTION
Persuasion is defined as an act of influencing the minds of others by
arguments or reasons, by appeals to both feeling and intellect; it is the
art of leading another man's will to a particular choice, or course of
conduct. No one doubts this is what trial lawyers do every day in the
courtroom-and that is what this article is about.
Much literature has been written on this subject, a literature which
reflects many new insights about human behavior and communication.
In experimental social psychology, persuasion is one of the major areas
of specialization. Volumes have been written on propaganda and com-
munications, psychological warfare, advertising and industry, scientific
mind-changing, religious conversions, confessions and indoctrination,
and brain washing. Some of the questions raised in this literature have
a profound impact on the art of persuasion in the courtroom. For
example, why are some trial lawyers perceived as highly trustworthy by
some people, yet, at the same time, untrustworthy by others? When both
sides of an argument are presented, will the arguments heard first have
any advantage over those heard last? Is persuasion in the guise of an
emotional appeal as effective as a rational communication? What
characteristics of recipients affect their persuasibility? Though the voice
is the most frequently used channel of communication in the court-
room, is it the most effective? If not, what is? Charts? Films? Drama?
This article is an attempt to answer these questions in light of the
-experiments in social psychology on persuasion, with support from the
knowledge other sciences have provided us. Also, these issues will be
-discussed from the vantage point of the trial lawyer.., who may have
never conducted. an experiment in social psychology, but who is, never-
theless, a master of the art.
