LEGITIMIZING CHARACTER EVIDENCE


                                Justin Sevier*

                                  ABSTRACT

    Modern   consensus among  legal commentators  is that character evidence-
when   used  to show   that an  individual behaved   in accordance   with  her
predisposition to commit some  act-is an illegitimate form offact-finding proof
This consensus  is codified in the Federal Rules of Evidence, which forbids the
use ofmost  propensity evidence at trial. Defenders ofthe ban suggest, without
empirical proof  that jurors would overvalue the probative worth ofpropensity
evidence  and that the public would balk at the inclusion of such evidence as a
matter  of legal procedure. This Article suggests that this view is misguided, its
assumptions  are incorrect, and that policymakers should consider lifting the ban
on propensity evidence.

    This Article reports the results of three original experiments, which examine
 the conditions under which the public is willing to legitimize legal verdicts that
 rely on propensity evidence.  The psychological  literature suggests that two
 elements must be satisfied for the public to legitimize an evidentiary rule: (1) the
 public must perceive the rule as promoting  decisional accuracy, such  that it
 increases the likelihood that the factfinder reaches the correct verdict, and (2)
 the rule must promote  procedural justice,  such that people believe that the
fact finder has reached  its decision according to notions of fair play. Social
psychology  research  on  person perception  suggests  that jurors are more
competent  to evaluate character evidence than legal commentators believe, and
research on procedural justice suggests that the inclusion ofpropensity evidence
may  increase the popular legitimacy of legal verdicts.

    These  experiments, which  surveyed  over 1,200  participants, support the
position  that propensity evidence  is a legitimate form  of trial proof They
demonstrate  that jurors attend to propensity evidence when  it is presented to
them,  but they afford such evidence significantly less weight than they do most
other evidence at trial. Moreover, jurors demonstrate marked competency   with
propensity  evidence: they discriminate between potential accuracy-enhancing
