Blake has developed a new measure of personality to assess whatpersonality type people have. It is called the “BlockbusterPersonality Type” measure. The measure includes images from the topten most popular Hollywood movies in the last ten years and asksrespondents to describe what is happening in the scenes. Responsesare scored in terms of how consistent they are with the originalmovies, and how much respondents show empathy for the differentcharacters in the scenes. As a result of this scoring, respondentsare classified as either being either “active heroes”, “passivevictims”, or “conniving villains”, reflecting the hidden desiresand goals that they were born with.

Blake wants to encourage people to use the test for selectionand recruitment in organisations around the world, so he collectsinformation about the test’s reliability and validity. He asks hisfirst-year psychology class to take the test at the start ofsemester and at the end of semester and compares their scores for ameasure of reliability. To test validity, he uses scores on thetest to predict how well his students do in their universitystudies.
