Assessing the Reliability and Validity of Personality Tests

Within the past few decades, popular psychology has become a powerful driving force for psychological research; it influences which studies get funding, which theories gain traction, which even psychologists achieve notoriety. Personality psychology in particular has grown in the past several years, and as such there are a number of different personality tests available on the internet. Millions of people make use of these tests, so it is important that they have accurate information about which tests are legitimate and which are not. My research seeks to assess the most commonly used personality tests on several main factors. To do this, I ask the following questions: How do psychologists measure the reliability of a personality test? What does the existing empirical evidence suggest about the reliabilities of well-known personality tests? How do psychologists measure the validity of a personality test? What does the existing empirical evidence suggest about the validities of well-known personality tests? What value and applications do personality tests provide both within and outside the field of psychology? After conducting a literature review, I will create a website in order to spread information to the public about my findings.
