Personality and Individual Differences (PAID) is a scientific journal published bi-monthly by Elsevier and founded in 1980. PAID is the official journal of the International Society for the Study of Individual Differences (ISSID). 
The journal has, e.g., published description of the revised version of Eysenck Personality Questionnaire—the article being one of the most cited of the journal. A sex and intelligence article by Helmuth Nyborg from 2005 led to strong reaction in the Danish media and a subsequent investigation of his study.
