Burt, Sir Cyril (1883-1971), was an English psychologist who pioneered in intelligence testing among children. His work led to the introduction of the Eleven-Plus examination, a test given to 11-year-old children in the United Kingdom to determine if their future education should be technical or in the arts. In 1976, after Burt's death, colleagues learned that he had falsified some of the research data upon which his theories were based.
