DAUBERT & DANGER: THE FIT OF EXPERT PREDICTIONS IN
CIVIL COMMITMENTS
A lexander  Scherr .............................................................................. I
In civil commitments, courts face the task of predicting the dan-
gerousness of a mentally ill person and often turn to experts for
help. Recently, the reliability of expert predictive testimony has
improved; yet the best predictions still fall far short of reasonable
certainty. Predictive science itself remains under scrutiny and is
the subject of extended research and debate.
The modern handling of expert testimony, initiated in Daubert v.
Merrell Dow Pharmaceuticals, Inc., might suggest that courts
should exclude such unreliable expertise. The Daubert rules seem
to imply a reliability standard under which trial courts should ex-
clude expertise that lacks scientific validity. Such a test should
require the exclusion of predictive expertise.
Yet no appellate court has ever done so; this Article assesses
why. This Article reviews Daubert and its progeny, describes the
science of prediction, and analyzes how predictive uncertainty af-
fects and interacts with civil commitment law. It analyzes judicial
decisions on the admissibility of predictions under both Daubert
and the alternate Frye standard.
From this review, a more complex view of Daubert emerges. In-
stead of a test of scientific reliability, Daubert requires courts to
weigh the reliability of expertise against its fit to the demands
of a given case. Courts may admit even such deeply unreliable
expertise as predictive testimony where it bears a sufficiently
strong fit to the needs of the case. This Article proposes a meth-
odology and an analytical structure with which to assess fit under
Daubert, and suggests further directions for both doctrinal and
theoretical development of the standard.
