“…It has been shown that when given appropriate instructions relatively naive subjects can answer personality inventories so as to appear neurotic (Keehn, 1962;Stanley & Salas, 1965), extraverted, aggressive or extremely normal (Braun & Gomez, 1966;Gomez & Braun, 1967;Handler & Shrader, 1966;Radcliffe, 1966;Stanley & Salas, 1965). Lie scales are often included in personality inventories in order to detect subjects attempting to give a favourable impression of themselves, the most notable exception being the 16 PF and its derivatives, although it is clear that such a scale is required (Handler & Shrader, 1966;Radcliffe, 1966). None of these inventories, however, includes a scale designed to detect malingerers.…”
