Do jurors expect to hear scientific evidence in criminal cases?

Many jurors expect to hear scientific evidence in criminal cases.

Shelton (2008) surveyed a jury pool to learn what percentage of jurors expected to hear scientific evidence in different types of criminal cases.

Scientific evidence of some kind was expected by 46% of jurors in every criminal case, by 74% in murder cases, by 43% in rape cases, by 73% in breaking and entering cases, and by 55% in crimes involving a gun.

Roughly half to three-fourths of jurors expect to hear scientific evidence in criminal cases.
