Summary

Hi all,

 

My research this summer was about personality testing, and my primary purpose in conducting this research was to create a website detailing the structure and scoring of four different personality tests as well as assessing their reliability and validity based on the findings of existing research. The four tests I chose to study were the Minnesota Multiphasic Personality Inventory, the Eysenck Personality Questionnaire, the Myers-Briggs Type indicator, and the revised NEO personality inventory. Of the found that the NEO-PI-R was the most widely supported by psychologists, but a direct comparison of the four tests is difficult because they serve different purposes– the MMPI, for example, is used in clinical settings to analyze psychopathology, while the MBTI is used mostly in business settings today to determine the motivational styles of employees. The implications of the wide reach of personality tests are numerous, but one thing in particular that concerned me is the fact that in many companies, the MBTI is a required test for all employees and can sometimes affect whether and employee is hired and/or promoted, but its reliability and validity have been seriously questioned by many psychologists. As a whole, personality tests are useful, but there are many people who trust them implicitly to accurately categorize human personality, and my research has shown me that this is rarely the best course of action.
