Jurymen... have been prone to say that once the opening statements were
made there was nothing left to the case.I
[A]s many as 80 to 90 percent of all jurors have reached their ultimate
verdict during or immediately after opening statements?
Finally,... keep an open mind regarding each issue in the case until all of
the evidence has been received?
I. INTRODUCTION
The question of when and how jurors form opinions about evidence
presented at trial has been the focus of seemingly endless speculation. For
lawyers, the question is how to capture the attention and approval of the jury
at the earliest possible point in the trial. Their goal is to maximize the
persuasiveness of their arguments--or at least to minimize the persuasiveness
of those of the opposing side. Judges, in contrast, are more concerned about
prejudgment. They regularly admonish jurors to suspend judgment until after
all the evidence has been presented and after the jurors have been instructed
on the law.4
