Cyril Burt fraud or framed?

"When Sir Cyril Burt died in 1971, he was widely regarded as Britain's most eminent educational psychologist whose studies of gifted and delinquent children, contributions to the development of factor analysis, and research on the inheritance of intelligence had led to an international reputation. Within five years of his death, however, he was being publicly denounced as a fraud who had fabricated data purporting to show that human intelligence is genetically determined. Careful examination of the published data revealed serious inconsistencies that raised questions about their authenticity. The case has divided the scientific community ever since, and spilled over on several occasions into the popular press."
