Dr. James Loren Pryor, M.D. is the psychologist for the school district in which Springfield Elementary School is located. Dr. Pryor is one of the few employees at Springfield Elementary School who seems to actually be qualified in his field, despite relying on long outdated psychological methods such as using calipers on children's heads to conduct a phrenology analysis of children's mental status; phrenology was discredited in the scientific community by the 1840s. He does have a slight tendency toward gullibility, as Bart easily tricked Pryor into sending him to a school for gifted children by. Later, however, Pryor recommended that Bart repeat the fourth grade and refused to back off of his recommendation, in spite of Bart's protests. Dr. Pryor also seems to be prone to occasional absent-mindedness. When Bart was in kindergarten, Homer and Marge saw him to discuss problems Bart was having with adjusting to school. Pryor said it was due to Bart's 'flamboyantly homosexual tendencies,' and then corrected himself when he realized he was looking at Milhouse's file instead of Bart's. (Source: Fandom.com, CC BY-SA)
