But in an interview with The New York Times after a newspaper raised doubts about Justin's accomplishments, Ms. Chapman admitted that many of the records attesting to his superior intelligence were a sham. Ms. Chapman said she falsified the records of the I.Q. test given when Justin was 3. The SAT scores, she said, belonged to a former neighbor's son. She also said Justin had studied the manual for the Stanford Binet Intelligence Scale before taking the test in April 2000.
