S ummary . A new method of encouraging truthful answers to a questionnaire was investigated. 262 school pupils aged 12 and 13 years completed a revised version of the Junior Eysenck Personality Inventory. The scale was administered to half the group (controls) with the normal instructions while the others (experimental group) were, in addition, given information drawing attention to the existence of a ‘lie’ scale. The experimental group obtained a lower L score, and a higher score on psychoticism, and neuroticism (boys only); the effect on extraversion was not significant. The results from the experimental instructions were found to compare favourably with those from alternative ‘correction’ procedures, such as eliminating individuals with high L scores from the group analysis, or statistically adjusting scores on the basis of their correlation with L. It is thus suggested that the procedure of warning subjects about the presence of a ‘lie’ scale may prove useful as a standard practice in personality assessment.
