ABSTRACT

One obvious way to understand the relationship of individual differences to work-related behaviour is to examine the applied literature on personality testing in the workplace. Psychological tests, attempting to measure individual differences related to occupational behaviours, have been used for over 60 years, and there now exist nearly 80,000 occupational-related tests. Both world wars, particularly the second, were particularly important for the ‘testing business’ and most armed services are still active users of psychological tests for selection and training.
