"The Justice may believe this appropriate either (1) to avoid prejudice which might arise because the assertion that the principle, or technique, has a "scientific" basis may import an objectivity which could unduly influence the jury as a lay fact-finder or (2) to assist the presiding Justice in his responsibility to determine relevance, within the definition of Rule 401 M.R.Evid., i. e., whether the proffered testimony is likely to make the existence of any fact or consequence more probable or less probable than it would be without the evidence."

Decided: 1/25/1985

The proffer stated that the expert would testify concerning: (1) the "forgetting curve," i.e., the fact that memory does not diminish at a uniform rate; (2) the fact that, contrary to common understanding, stress causes inaccuracy of perception and distorts one's subsequent recall; (3) the "assimilation factor," which indicates that witnesses frequently incorporate into their identifications inaccurate information gathered after the event and confused with the event; (4) the "feedback factor," which indicates that where identification witnesses discuss the case with each other they can unconsciously reinforce their individual identifications; and (5) the fact that studies demonstrate the absence of a relationship between the confidence a witness has in his or her identification and the actual accuracy of that identification.[6] ...

Cir.1923), is much criticized, has never been adopted in Maryland, and I am opposed to its adoption. (2) The decision here is out of step with that of a number of respected courts as to the basis for admission of evidence concerning expert opinions related to fingerprints ballistics, X-ray, and the like. (3) The decision here is out of step with our prior Maryland holdings concerning expert testimony. ... It is because 457*457 he stated a reason for his conclusion that the voices are identical, not relying solely upon his aural comparison, that the case goes back for a new trial, although Chief Judge Prescott said in Miller v.
