 Friedman, R. D. (1991). Character Impeachment Evidence: Psycho-Bayesian Analysis and a Proposed Overhaul, 38 U.C.L.A. L. Rev. 637, 642-643. The prohibition against propensity evidence is deeply engrained. Given the prohibition, a violation of it must be considered prejudicial without regard to whether, in determining the facts, the jury likely relied more on the evidence than would be rational; any reliance at all is deemed improper. And because the propensity evidence is likely to affect the jury powerfully, both in guiding its fact finding and in altering the effective burden of proof, the prejudice is often extreme. Nevertheless, evidentiary rule makers have concluded that, because the jury is so dependent on the testimony of witnesses, it must have a relatively full base of information on which to assess their credibility.
