“…Researchers have paid special attention to instructions in death penalty trials, as over a dozen studies have tested the infl uence of death penalty jury instructions in states including California (Haney & Lynch, 1994, Missouri (Wiener et al, 1995 ), North Carolina (Luginbuhl, 1992 ), South Carolina (Eisenberg & Wells, 1993 ), Florida (Otto et al, 2007 ); Pennsylvania (Foglia, 2003 ), and Tennessee (Blankenship, Luginbuhl, Cullen, & Redick, 1997 ). Results are generally the same as with other jury instructions: jurors have poor comprehension of instructions, generally ranging from 25 to 70 % accuracy depending on the topic (e.g., Blankenship et al, 1997 ;Frank & Applegate, 1998 ;Wiener et al, 1995 ).…”
