ABSTRACT: This article reports on a study of the factors associated with jurors'
assessments of experts' believability. A total of 156 former jurors from 24 civil cases
tried in Dallas Country, Texas, responded to a telephone survey. Multivariate analysis
revealed no statistically significant associations between the occupations of the experts
or the characteristics of the jurors, on the one hand, and the believability of the experts,
on the other hand. Perceived qualifications, familiarity with the facts, good reasoning,
impartiality, and the side calling the expert were associated with believability. We
conclude that jurors make expert-specific decisions based on rational criteria.
