What is the test for "prejudicial or damaging" evidence in a criminal case?

naturally flows from relevant, highly probative evidence. '[All] evidence which tends to prove guilt is prejudicial or damaging to a defendant's case. The stronger the evidence, the more it is "prejudicial." The "prejudice" referred to in Evidence Code section 352 applies to evidence which uniquely tends to evoke emotional bias against the defendant as an individual and which has very little effect on the issues. In applying [Evidence Code] section 352, "prejudicial" is not synonymous with "damaging."' [Citation.]" (People v. Karis (1988) 46 Cal.3d 612, 638.)
