I'm not sure the results of my testing describe me correctly. Accuracy depends to some degree on who has created the test and the amount of research underlying it. A professional test author will write descriptions associated with different scores based on the way knowledgeable acquaintances have actually described people obtaining the score. The authors of self-assessment tests found in popular magazines base their interpretations more often on their own intuitions than on actual research findings. Accuracy depends partly on the length of the test.
Longer tests are generally more accurate than shorter tests.
Ten items is about the minimum number of items for a reasonably valid personality scale. Accuracy also depends on how precisely the test tries to categorize you. A test that tries to predict whether people perceive you as above average or below average with regard to a trait will be correct about 70 percent of the time. If you are uncertain about the accuracy of your test results, you should share them with people who know you well to get their views. That depends on the scales the test contains.
