Final answer:
Polygraph testing, often prohibited by the Employment Standards Act in some provinces, measures physiological arousal to assess honesty but lacks definitive evidence of its reliability. Other personality assessments, such as the MMPI, use true/false questions to assess personality traits without the same ethical or validity concerns.
Step-by-step explanation:
Personality Assessment and Integrity Testing
The use of graphic responses tests is a method of integrity testing. However, within the context of the Employment Standards Act in some provinces, certain methods are prohibited. Specifically, polygraph testing (C) is often banned due to questions about its validity and the ethical considerations surrounding its use. Polygraphs measure physiological arousal that may occur when a person is not being truthful. However, there is no definitive evidence indicating that lying is associated with a unique pattern of physiological arousal, which casts doubt on the reliability of polygraph testing as a measure of honesty.
When assessing personality for employment or legal purposes such as in law enforcement, a variety of tests can be used, including self-report inventories like the Minnesota Multiphasic Personality Inventory (MMPI), which consists of true/false questions. Unlike polygraph tests, the MMPI and other personality assessments like projective tests (e.g., the Rorschach Inkblot Test) or the Myers-Briggs Type Indicator (MBTI) do not fall under the same level of scrutiny or prohibition in employment contexts.
