his university, he successfully fought to have his case held in public and was eventually exonerated. According to Scarr: "Eventually, Needleman was found guilty of misrepresentation and had to retract research reports in the journals that published them." However, no retractions were issued, only mild corrections. According to environmental psychology professor Colleen F. Moore, Scarr and Ernhart "found a published graph that was slightly in error, and Needleman eventually published a correction". The lawsuit and subsequent inquiry remain controversial; according to philosopher of science Clark N. Glymour, "Scarr and Ernhart are sometimes dismissed as tools of the lead industry, but I know of no evidence that they were other than sincere." However, Glymour thinks that Scarr and Ernhart were wrong on their methodological findings. EPA scientist Joel Schwartz told Newsweek in 1991 that a reanalysis of Needleman's data incorporating the factor of age, which had been excluded, "found essentially the identical results". By that point, Needleman's research had been superseded by newer research used to justify even lower limits of allowable lead.
