01

1980–1995

1980–1995: Posthumous institutional condemnation for fraud, followed by renewed debate without definitive rehabilitation

No legal proceedings

In 1980, the British Psychological Society's Council publicly accepted the conclusion that Burt had fabricated data. Subsequent books re-examined the case, some defending Burt and others finding his later data unreliable. In 1992, the BPS considered it no longer appropriate to issue another institutional verdict.

1976–années 1990

1976–1990s: Controversy over Margaret Howard and Jane/J. Conway, collaborators difficult to identify

Investigation

After Burt's death, journalists and researchers sought to identify Margaret Howard and J./Jane Conway, described as collaborators or co-authors. The initial inability to locate them fuelled allegations that Burt had invented assistants to make his research appear independently supported.

1947–1967

1947–1967: Editorial control, self-citations and alleged pseudonymous publications in British Journal of Statistical Psychology

No legal proceedings

Burt exercised exceptional influence over the Journal, later the British Journal of Statistical Psychology, while publishing extensively in it himself. The Burt affair subsequently included allegations that he used pseudonyms or collaborators' names to produce articles supporting his theories and rebutting criticism.

1943–1966

1943–1966: Almost identical correlations in twin studies despite increasing sample sizes

No legal proceedings

Burt's studies of identical twins raised apart reported almost unchanged IQ correlations even as the number of pairs increased significantly. This consistency, noted after his death, became one of the principal indications used to suspect fabrication or reconstruction of data.

années 1940–1960

1940s–1960s: Influence on school selection and controversy over 11-plus and equal opportunities

No legal proceedings

Burt's ideas about general intelligence, psychometric measurement and individual differences influenced the intellectual culture of British school selection. The 11-plus system and early selection were criticised for their social impact and bias towards middle-class children.

années 1920–1940

1920s–1940s: Eugenicist involvement and research on poverty, fertility and "deficiency"

No legal proceedings

Burt was an important figure in the British eugenics movement and participated in research linking intelligence, poverty, crime, fertility and heredity. This work contributed to social policies and debates now strongly criticised for biological determinist and class-based assumptions.

II. Documented background

Documented biographical or institutional milestones (elections, appointments, foundings, acquisitions…). These are not controversies and are not counted as such.

  1. 1909–années 1930

    1909–1930s: Strongly hereditarian theory of intelligence based on social and educational comparisons

    Burt's early work on intelligence tests led him to describe general intelligence as largely innate and hereditary. His comparisons between children from different social backgrounds formed part of a view in which class differences partly reflected natural abilities.

III. Constellation of documented links

No documented link with another published profile for now.

Two profiles are linked when a documented controversy of one names the other. The link points to that controversy and its sources; it does not indicate a personal relationship.
