<abstract>The article presents two procedures for adjusting response distributions for data already collocted with open-ended response modes and hence vulnerable to an exaggerated presence of 50%. Each procedure infers the prevelance 50% had a numeric probability scale been used, then redistributes the excess. The two procedures are validated on some of our own existing data and then applied to judgments elicited from expert in groundwater pollution and bioremeditation</abstract>
