Measuring Personality
* Research has shown the personality tests are useful in hiring decisions and help managers forecast who is best for a job. * The most common means of measure personality is through self-report surveys, with which individuals evaluate themselves on a series of factors, such as “I worry a lot about the future.” * Problems with self-reports: respondents may lie or practice impression management to create a good impression. They rate themselves about half a standard deviation more conscientious and emotionally stable then if they are taking the test to learn more about themselves. Bad mood can affect the accuracy of the score. * Observer-ratings surveys: provide independent assessment of personality. Done by co-worker or another observer, sometimes with or without the subject’s knowledge. * Observer-ratings surveys are better predictors of success on the job. * Combination of self-report and observer-reports predicts performance better than any one type of information.
