Fig. 1From: Estimating the proportion of guilty suspects and posterior probability of guilt in lineups using signal-detection modelsPosterior probability of guilt (PPG) as a function of base rate of guilt. Solid curve based on d’ = 1.8; dashed curve, d’ = 1.0 (c = 1 in both cases). Red lines at PPG = 0.95 (reasonable doubt) and 0.51 (probable cause)Back to article page
