International Society for the Study of Individual Differences

The International Society for the Study of Individual Differences (ISSID) is a scientific society founded in 1983 that fosters research on the measurement, structure, dynamics and biological bases of individual differences in temperament, intelligence, attitudes, and abilities. Its first president (and one of its founders) was Hans Eysenck. The society investigates the major dimensions of individual differences in the context of experimental, physiological, pharmacological, clinical, medical, genetical, statistical, and social psychology.

ISSID holds Personality and Individual Differences (PAID) as its official scientific journal[1] and hosts a conference on individual differences every other year. The current president is Philip Corr, professor of psychology at City University London.
