Suppose that a researcher wants to measure all of the major aspects of personality.The researcher proceeds by using his or her own judgment to choose a large set of traits that seem diverse,interesting,and important.Which of the following would be a likely shortcoming of this approach?
1)Despite being a large set of traits,it might completely miss some important aspects of personality
2)Some of the traits within this set might be rather similar to each other,and therefore somewhat redundant
3)Other researchers might measure different sets of traits,making it difficult to communicate,compare,or combine results.
